Onkyo AV receiver

No matter what you want to hear or see, the Onkyo receiver delivers everything in superb sound: music, games and, of course, movies. All settings are simple and easy to make. It's the perfect match for your Teufel sound system.

  • Teufel Onkyo Receiver
    Complete package

    The Onkyo receiver comes with a remote control, FM and MW antenna and measurement microphone.

    If you choose the bundle set, you will also receive speaker and subwoofer cables.
  • For vinyl fans

    The Onyko receiver has a phono input (MM) e.g. for TEAC record players.
  • Now with Amazon Music

Finish

Beautifully finished. Made from sturdy MDF with inner struts. Teufel speakers have a timeless design and long durability.

  • Teufel Stereo-Lautsprecher Ultima 20 Mk3
    Lettering against high-gloss tweeter and matte speaker cabinet
  • Teufel Stereo-Lautsprecher Ultima 40 Mk3
    Easy to clean finish with scratch-resistant surface
  • Teufel Stereo-Lautsprecher Ultima 40 Mk3
    High-quality fabric mesh with revolving bevel - the frequency response is only minimally affected
Innovative technology

The smaller Ultima also produces a big sound, because it is full to the brim with the latest speaker technology.

Unmatched in every situation
The Ultima 20 is a high-quality bookshelf / rear speaker that makes no compromises. As an individual stereo pair or as part of a home cinema set surround set up, the Ultima 20 comes into its own. The appearance and acoustics fit perfectly with those of its big brother. The speakers can be positioned on a shelf, on speaker stands or wall mounted.
A centre speaker with that little bit extra
Two large mid-range drivers in a D'Appolito arrangement ensure powerful, distortion-free sound and high speech intelligibility for games and movies - even at low volumes. The sound is of course exactly matched to the Ultima 40 or 20. It can be easily mounted on the wall, but thanks to its slim design, it also looks great on a stand or on a shelf.

Design and materials

No shortcuts were taken when it came to optimising our Ultima speakers. Here are the highlights of the new range:

  • Teufel Stereo-Lautsprecher Ultima 40 Mk3
    High-gloss tweeter and matte speaker cabinet
  • Teufel Stereo-Lautsprecher Ultima 40 Mk3
    Easy to clean finish with scratch-resistant surface
  • Teufel Stereo-Lautsprecher Ultima 40 Mk3

  • Teufel Stereo-Lautsprecher Ultima 40 Mk3
    Modern, timeless design
  • Teufel Stereo-Lautsprecher Ultima 40 Mk3
    The solid, gently curved MDF housing is the result of more than 30 years of Teufel experience and modern speaker technology.
3-way system
The foundation for good sound lies in the design of the 3-way system, which has been further developed and improved over many years. The drivers work together in harmony across all frequency ranges, resulting in an extremely smooth and clear sound reproduction.
  • Teufel Stereo-Lautsprecher Ultima 40 Mk3
    Close-fitting driver for a vivid, balanced sound reproduction
  • Teufel Stereo-Lautsprecher Ultima 40 Mk3
    Two large bass reflex tubes with a trumpet tube attachment minimise any current noise - no other manufacturer makes this much effort.
  • Teufel Stereo-Lautsprecher Ultima 40 Mk3
    All drivers were measured with a laser using Klippel measurement technology in order to detect the smallest tolerances.
Double bass – a real Teufel in every respect

Especially if you're looking for full bass without a subwoofer, this full-range speaker is the right choice. Two large 165 mm fibreglass woofers provide a particularly precise low-frequency reproduction. The long stroke ensures distortion-free playback even at high levels. You don't need an additional subwoofer.

Teufel Stereo-Lautsprecher Ultima 40
T 10 Subwoofer

For the first time Teufel offers a subwoofer that can be used either as a front-firing or down-firing subwoofer. Don't let the 150-Watts fool you. The new Class-D amplifier is highly efficient and produces extremely low-noise like classic amplifiers that consume 300-Watts.

  • First-class active subwoofer, which can be used either as a front-firing or down-firing subwoofer
  • 250 mm diameter woofer
  • Power: 150-Watt, highly efficient Class-D power amplifier with low power consumption
  • Automatic on and off
  • Extensive configuration options and protection circuit
  • Can be tilted forwards or backwards, and feet are adjustable
  • Integrated wireless module - works with Trios, Duett, One, Cinebar/Cinesystem Pro, CoreStation and Impaq, the Onkyo receiver requires the Subwoofer Wireless Receiver.
Dolby Atmos und DTS:X

Dolby Atmos is an object-based reproduction method from Dolby Laboratories. The procedure assigns an individual signal to each speaker. An impressively realistic sound experience is achieved by the reflective loudspeakers radiating upwards, whose sound waves reflect on the ceiling and thus return to the listener.

The result is authentic 3D sound. You can hear leaves rustling around you, rain pouring down in the rainforest, or airplanes and helicopters flying overhead.

Dolby Atmos has established itself as a playback method and is used on most new Blu-rays. Streaming providers such as Netflix also play films in Dolby Atmos.

DTS: X is the competing format to Dolby Atmos. The complete set presented here is 100% compatible to both formats.

A 5.1.2 set contains two reflectors. If you use the set in rooms over 20 m² we recommend four reflective loudspeakers.

"delivers very decent bass for its size"
Stereoplay 11/2018
"Once in position, the Berlin speakers allowed the music to be experienced as lively, full-bodied and balanced. The timbre of the Ultima 20 Mk3 was slightly on the bright side, but never tinny. The bass didn't hide away either, even with electronic beats [...]."

"[...] The Ultima 20 Mk3 offers a shaken sense of balance and also delivers very decent bass for its size [...]."

"played dynamically and created a lively sound image"
Audio 11/2018
"An Ultima sounds like an Ultima, that's what we expected. It played dynamically and created a lively sound image. Even though the reproduction sometimes seems too closed and Marla Glen's voice showed a hint of too much colour, the loudspeaker was pleasantly striking compared to the 2016 model with a somewhat airier high-frequency reproduction. This gave the sound a little more three-dimensionality."

"The Ultima 40 is a bargain when it comes to third generation and is a winner the best sense. Not one thing out of place, sonically perfectly balanced sound. Not quite a miracle, but a loudspeaker with which you can enjoy listening to any kind of music. I don't know of a better alternative for all people who only want to spend a little money and still want to enjoy a louder sound. This is also in part, as the Ultima 40 has been developed to work practically with smaller amplifiers and installation in smaller rooms." (Translated from German)

"If you’re looking for a full surround sound system, you have the option of the 5.1 Ultima Series which is an absolute gem of a system"
Outer Audio 05/2019
"If you’re looking for something different, then the Teufel Ultima 40 is certainly one to check out. I put these on par with the Klipsch R-24F. However, I would say the R-24F has a more controlled bass response than the Ultima 40. If you’re looking for a stereo pair, then you should definitely consider the Ultima 40 Active over the passive model. You’ll get better value for money by not having to spend extra on an amplifier and cabling as well as a more efficient speaker with factory fitted and tested amplification. If you’re looking for a full surround sound system, you have the option of the 5.1 Ultima Series which is an absolute gem of a system and also very affordable for the size and quality you get."

Help regarding this product
Do I also have a 6.1/7.1 playback for a 5.1 recording?
Usually, all 6.1/7.1 AV Receivers can generate a 6.1/7.1 playback from a 5.1 recording. The procedure is comparable with the Dolby Pro Logic Decoder, which generates a matrix circuit from the stereo signal of a centre channel.

The AV Receivers thus generate a rear centre channel from the rear R/L channels of a 5.1 recording through the matrix circuit. The stronger the rear R/L effects on the DVD, the stronger the signal from the rear centre.
Can I connect the LT 4 directly to a DVD player or PC?
No.

The LT 4 is a partially active system that requires AV receiver operation. It has a built-in amplifier that only supplies bass tones in the subwoofer housing That is why an "AV Receiver", i.e. a combination of radio receiver and multichannel amplifier, is essential for using the LT 4.

The subwoofer is connected from the Line In R input to the AV receiver's sub out jack using a mono RCA cable, while the three front satellites are connected to the three speaker outputs of the AV Receiver using the speaker cable and are supplied with power from there.

Connect signal-emitting source appliances such as DVD player or PC etc. directly to the corresponding input jacks on the AV Receiver.
When would it be worth upgrading my 5.1 system to 6.1/7.1 sound?
Naturally 5.1 channel systems that play back all of the sound tracks contained on the DVDs already offer an excellent home cinema experience.

For the new 6.1 or 7.1 sound formats, a rear centre channel is controlled in addition to these channels. This channel, coded in the stereo effect channels, enables the better positioning of effects and music signals directly behind where you are sitting.

If using two speakers for the rear centre channel, the optimal seating position is not tailored to an individually specified position, i.e. you don't have to be seated in the exact centre.

In the following cases we would recommend upgrading to a 6.1 or 7.1 system:

• Your sitting position is not always dead centre, or you often have several viewers

• You have had a 5.1 system for a very long time and would like an improvement

• Your AV amplifier/receiver is designed as a 6.1 or 7.1 receiver and offers the corresponding connection possibilities

• You can also set up one and/or two rear centres. If you are currently building/renovating your house or flat, we would recommend you lay the cables for the additional rear centre channels in any case.

• Modern BluRay players usually issue a true 7.1 surround sound signal at all digital outputs and are thus optimally suitable - presuming the relevant AV Receiver - as a signal transmitter for a 7.1 channel home cinema system.
How do I upgrade my system to a 6.1 or 7.1 sound format?
The choice of speaker(s) depends on the AV Receiver/amplifier. This has an additional power amplifier for one rear centre (6.1) or its two (7.1). You can easily see this by the wattage (e.g. 6 x 100 watt or 7 x 100 watt). To the existing (side) rear speakers for right/left (5.1 technology), one or two additional rear centres are utilised in addition (6.1 or 7.1 technology).

• My AV amplifier/receiver has six connections/power amplifiers (6.1):

In this case we recommend connecting the same centre at the rear that you also used in the front area.

• My AV amplifier/receiver has 7 connections/power amplifiers (7.1):

If you already use dipoles or direct emitters for your 5.1 system, then you have a choice of either supplementing two more dipoles or two direct emitters. For wall assembly and a short distance from the seating location to the rear wall (less than 1.00 metres), we would recommend dipoles. As soon as you want to set up the speakers on bases or on a shelf, then direct emitters would be the better choice.

Information:
Even if the AV Receiver/amplifier only has the connection and power amplifier performance for one rear centre, it is still possible to connect two instead of just one speaker through series connection.

Exception:
• The AV amplifier/receiver has seven connections/power amplifiers, but I can only set up one rear centre. As the 7.1 AV amplifiers/receiver also offer the option of operating just one of the two outputs (usually can be set in the speaker set-up!), you can also only connect just one rear centre.

Here we recommend connecting the same centre to the rear that you also used in the front area. For short distances to the listening location (less than 1.00 metres), a dipole would be the better choice - especially if you are also using dipoles at the sides.
Is it a problem if the speakers are at different distances to where you are sitting?
Since the distance and volume of every individual speaker can be adjusted for the digital home cinema receivers, asymmetrical set-ups can be easily compensated. 
How do I equalise my home cinema system with the help of a sound level meter?
Take the level meter with you to the listening position and point the measuring device directly towards the front centre speaker. Now start the sound generator of the receiver (or of the sound card or DVD player) and equalise all speakers in succession to the same level.

The position and alignment of the measuring device should not be changed during this procedure. For a Teufel sound level meter, proceed as detailed in the following:

1. Remove the protective tab from the battery.

2. Set the weighting to "A" - only the "A" position considers the full frequency range during measuring!

3. Set the response to Slow.

4. Set the Range to 70.

5. Start the test noise from your AV device.

6. Change the volume for every individual channel at the AV device so that the level meter shows 75 dB (meaning between +4 and +6).

7. Done!
What is the difference between the 5.1 and 7.1 configuration?
Compared with the 5.1 set, the 7.1 set has two extra speakers for the back rear centre channel.

The 5.1 channel set plays back all sound tracks on DVDs/Blu-rays and creates an excellent home cinema experience.

With the 7.1 sound format, a rear centre channel is also generated in addition to these channels and distributed to two further speakers (the "rear centre"). This channel, which is encoded in the stereo effects channels, allows better location of effects and music signals directly behind the sitting position.

If you use two speakers for the rear centre channel (i.e. installed 7.1 set), the optimum sitting position is not restricted to one specific place, so you don't have to be sitting exactly in the middle and several listeners can enjoy the best sound.
Where is the optimal place for the centre of my Lautsprecher Teufel Surround System in a 5.1/6.1/7.1 configuration?
Because the centre plays back spoken dialogue, this speaker must be positioned as centrally as possible under or over the TV/monitor or the screen.

If the centre is placed outside the area of 40 centimetres to 1.20 meter height, it should be slightly inclined or angled towards the listener.


My Bluetooth speaker produces a lesser quality sound with my Windows PC or laptop.
It could be that the speaker is connected as a device with speakerphone function. Please go to: settings menu > devices and printer > BOOMSTER (or other Bluetooth device). Right click on the device and remove the check mark next to the “speakerphone” option.
The iTeufel Air can't connect to my home network. What do I do?
Check that your password doesn't contain any special characters.
The AirPlay connection to my iTeufel Air is constantly being disrupted. What can I do?
Your WLAN may be set to transmission channel 13. This channel is only used within Europe. In some cases, devices that were developed for other countries are not supported by this channel.

Solution: Change the transmission channel on your WLAN router. We recommend channel 11.
What is AirPlay?
AirPlay technology from Apple allows you to stream your iTunes to an AirPlay-enabled playback device such as the iTeufel Air. In this way, each and every song, album, and playlist from your iTunes music collection can be conveniently accessed at the touch of a button.

Playback can be directed from an iPhone, iPod touch, iPad, or PC. If iTunes is installed on a PC or Mac, it is even possible to stream audio files to mulitple devices simultaneously for multiroom plackback.

AirPlay can be used with either WLAN, an ethernet connection, or a combination of both.
Do I need a THX amplifier for the THX speakers?
Not necessarily!

The receiver/amplifier must have bass management where the frequencies are distributed for the THX front/centre speakers and the THX subwoofer (cut-off frequency 80 Hz).

Also, the amplifier should exhibit a minimum rating of 100 watt per channel and match the speakers for performance (amplifier sine wave output = approx. long-term load of speaker).
Are THX speakers suitable for listening to music?
Of course.

Since THX speakers are optimised to play back multi-channel signals (4 or 5.1 channels), the front speakers permit the precisely staggered and very true to detail spatial playback, while the surround speakers ensure realistic room characteristics.

Both are also ideal requirements for playing back music.
Is THX compatible with Dolby Digital and DTS?
Absolutely!

The objective of THX home cinema systems is to play back film soundtracks with as much authenticity and quality as the original mix from the sound studio.

In all studios used for film dubbing, the soundtracks are mixed in a 4-channel version (Dolby Surround) and in a 5.1 channel version. The acoustics, equalizer settings and speaker configurations are absolutely identical.

THX systems are thus always able to play back soundtracks produced in this way absolutely true to the original. Because of the high technical and tonal requirements, the THX standard can be compared with the TÜV (German Technical Control Board) for cinema sound.

As opposed to the THX quality standard, DTS and Dolby Digital are procedures for compressing sound data.
What is so special about a THX System?
THX systems are the ultimate home cinema components.

All THX-licensed devices and speakers must demonstrate certain technical properties so that they can play back movie soundtracks produced for cinemas and correspondingly powerful cinema sound systems absolutely true to the original for home cinemas as well. This is only possible up to a certain point with conventional hi-fi systems.

The most important requirements for excellent home cinema sound are:

• That despite the considerable size difference between cinemas and home cinemas, the movie soundtrack can be played back in comparably smaller rooms with the correct tonal balance and three-dimensionality.

• That all sound channels are played back very precisely despite the complexity of a multi-channel soundtrack to be able to precisely locate and allocate all noises and voices.

• That the subwoofer is perfectly coupled to the main speakers.

• That the front speakers are (by sound) identical - indispensable for harmonious sound playback.

THX systems satisfy these requirements perfectly, as they consider all running processes concerning playback while the movie soundtrack is being mixed.
What are the differences between THX Ultra 2, THX Select and THX Multimedia?
THX is a quality standard that guarantees the best possible playback for a specific room size. Since THX was originally developed for cinema theatres, the specifications apply to room sizes that far exceed the average living room size.

THX currently differentiates three standards for speakers: THX Ultra 2, THX Select and THX Multimedia.

THX Select 2 only applies to AV Receivers/amplifiers.
THX Ultra 2 corresponds to the earlier THX with the uncompromising design of the components.

Comparison of the three THX standards:

Front speaker
• THX Ultra 2: Angle of radiation and frequency response strictly limited requirement, D'Appolito arrangement of speaker systems prescribed.
• THX Select: More generous specifications for angle of radiation and frequency response.
• THX Multimedia: Radiation behaviour corresponds to THX Select.

Surround speaker
• THX Ultra 2: Dipoles are compulsory.
• THX Select: Dipoles recommended, but not compulsory.
• THX Multimedia: Direct emitters in every respect.

Subwoofer - transfer frequency

• THX Ultra 2: 80 Hz
• THX Select: 100 Hz
• THX Multimedia: 130 Hz

Volume level

• THX Ultra: Continuous load 105 dB (front) / 102 dB (surround).
• THX Select: Short term load 105 dB (front) / 102 dB (surround).
• THX Multimedia: 103 dB at the listening location/desk at approx. 50 cm distance.

Performance profile

• THX Ultra 2:
More output performance than normal AV Receivers. Complies with the strictest requirements for minor background noise and minor distortion. Is designed for performance needs of large listening rooms up to 150 m².
• THX Select:
Structure of AV Receiver is simpler and thus more reasonably priced. Less performance required, therefore suitable for smaller and medium-sized listening rooms up to approx. 50 m².
• THX Multimedia:
Pure PC and/or multimedia speakers for use at the computer.

Speaker set-up

• THX Ultra 2: Arrangement and set-up strictly regulated.
• THX Select: Set-up and arrangement simpler and more flexible.
• THX Multimedia: Set-up of front speakers on the desk, rear speakers to the side and behind where you are sitting.
How can I upgrade my THX system to a 7.1 sound format?
With the THX 7.1 amplifiers/receivers, there is always the option of connecting two rear centre speakers. We would also recommend using four rear speakers. Due to the elaborate development of our rear speakers, our models can be used very flexibly for any application. Here we have to differentiate as follows: - You have a THX Select/Ultra 2 device and want to connect two rear centre speakers: if you already use dipoles or direct radiators in your 5.1 system, you have the choice of adding either two more dipoles or two direct radiators as rear centres. For wall mounting and/or at a short distance from seat to rear wall (less than 1.00 m), we would recommend dipoles that are also operated in dipole mode (for System 4 THX, for example, order 2 x additional S 400 D). As soon as you want to place the speaker on stands or on a shelf, we would recommend direct radiators (for System 4 THX, e.g. order 2 x additional S 400 FCR). As soon as you already use direct radiators with your 5.1 system, we would recommend the same type of direct radiators for the upgrade. You have a THX Ultra 2 unit and want to connect two rear centres: a circuit especially developed for THX Ultra 2 devices allows you to use two more direct radiators or two more dipoles in addition to the dipoles used as rear effect loudspeakers.
I want to save a Chromecast stream on the direct selection keys (not applicable to all devices). How can I do this?
For technical reasons, it is not possible to store Chromecast streams on the direct selection keys.
One advantage of streaming with Chromecast is that you can continue to use your usual music app. How can I check if my apps already support Chromecast?
Chromecast built-in already supports 100+ apps, including many popular music services, and works with the Chrome browser. You’ll find an exact overview of all Cast-enabled apps here:

https://www.google.com/intl/en_us/chromecast/built-in/apps/

Tip: If you didn’t find your app on this list, you may want to contact the provider directly and ask when Chromecast will be integrated. In the meantime, you should have no trouble finding an alternative from the large selection of Chromecast-enabled apps.
Ich habe eine eigene Sammlung von Musik mit hoher Qualität und möchte diese über eine Chromecast unterstützende Musik-App abspielen. Wieso werden mir die Titel nicht anzeigt?
Chromecast built-in can stream CD-quality audio up to 48 kHz. If your collection has a higher sampling rate, you can stream it via the Teufel Raumfeld App.
I also want to use Chromecast's multi-room function and stream to multiple speakers at the same time. How can I do this?
Multi-room streaming is also possible with Chromecast. To do this, create a grouping of speakers within the free Google Home app which you will need to install on your smart device. You can name created groups on the app.

After you create and name your groups, they will appear alongside individual Cast-enabled speakers in your music app.

Google Home App (Play Store)

App Store iOS
I use the Spotify app to stream to my speakers. I don't see any or not all of my Chromecast speakers under "Available devices". What could be the reason?
In order to stream with Chromecast built-in, you’ll need the most recent version of the Spotify App. We recommend updating your app and trying again. Please note that you will also require a Spotify premium account in order to stream to your speakers.
I like watching YouTube videos. Can I now use Chromecast to wirelessly output the sound of YouTube videos while watching them?
The wireless transmission of audio content from YouTube is possible with the following:

1: A computer running on either the Windows 10/8.1/8/7 32 bit, Mac OS X 10.9 (or higher) or Linux operating systems.

2: A current version of the Chrome browser. You can download the most recent version here:
https://www.google.com/intl/en/chrome/browser/desktop/

3: The Chromecast built-in extension for the Chrome browser (if not already integrated)

4: A least one Teufel Streaming device with Chromecast built-in registered to the same Wi-Fi network as the computer using the Chrome browser

Begin a YouTube video. Select the “streaming” option from the “more” menu in the Chrome browser. This will call up a menu displaying all Teufel Streaming devices in the network that can play back the audio.

Restrictions:
  • The video displayed on your screen and audio from your speaker may not be in perfect sync.
  • It is not currently possible to directly cast audio from the YouTube app for iOS or Android.

Step 1: Install the “Google Home App” and open the menu on the left side.

Step 2: Tap on the option “Screen/Audio streaming” and select the Teufel Streaming device you wish to cast audio to. An active connection will be displayed in your smartphone’s status bar.

Unfortunately, this option is not currently available for smart devices operating on iOS systems.

Step 3: Switch back to the YouTube App and start a video as you normally would. The audio will play from the Teufel Streaming device you just selected.

Please note that the picture and audio may not be in perfect sync.
Ich streame Musik direkt aus dem Chrome-Browser. Die Wiedergabe ist jedoch manchmal verzerrt oder setzt kurz aus. Was kann ich dagegen machen?
The most frequent cause of distortion and drops in playback is insufficiently fast data transfers from the PC to the WiFi speaker. Data transfer rates can be affected by the WiFi router and the internet connection. We recommend enhancing the performance by increasing the WiFi signal strength in the vicinity of your PC and speaker.
Ich verfüge über eine sehr große eigene Musiksammlung. Seit ich das Update mit Chromecast built-in durchgeführt habe, reagiert das System öfter nicht. Was kann ich dagegen unternehmen?
The processing of a large number of music files requires Teufel Streaming system resources. This is normal and comparable to a computer that has multiple programs running at the same time. For most music libraries, this does not pose a problem. For exceptionally large libraries, however, such as those in the terabyte range, the system might be strained to a point where normal streaming is compromised.

Solution: Restart all Teufel Streaming devices and deactivate Chromecast built-in.
Der Stream auf meine Teufel Streaming Geräte über Chromecast beginnt erst nach langer Wartezeit oder startet gar nicht. Woran kann das liegen?
There are many possible reasons why your music stream doesn’t start or only begins after a long delay. The following are the most common causes:

1) Chromecast built-in functionality can vary between providers. It’s therefore important to abide by the instructions given by the provider for using this technology. For instance, some request that users first cast and then start an audio stream while others recommend the reverse order of actions. If you are unsure whether you are casting correctly, please ask your app’s service team for assistance.

2) It can take around 20 seconds or even longer in some cases for a stream to be processed. Contact the provider of the music or audio service you use to learn more.
How can I tell if my Teufel Streaming/Raumfeld devices are compatible with Chromecast built-in?
Chromecast is supported by Teufel Streaming / Raumfeld devices which have a Raumfeld logo on the front panel and no external Wi-Fi antenna on the rear panel. Chromecast is also supported by the Raumfeld Soundbar / Sounddeck and the Teufel Sounddeck Streaming / Teufel Soundbar Streaming.
Wie kann ich das Chromecast built-in für aktivieren?
Chromecast built-in can be activated on your Teufel Streaming device once it has updated its firmware to version 1.60 and actualised the Teufel Raumfeld App (iOS/Android). The app will then automatically display the presence of Chromecast-enabled devices present in the network.

Manual activation can also be completed at any time in the Teufel Raumfeld App’s menu under “Music services”.
How must I set the impedance selector switch of my receiver for Teufel speakers?
Here is more detailed information from the AUDIOVISION trade magazine (Issue 4/03) on the subject of impedance settings of the AV Receiver:

Actually, it should be quite simple: Connect the speaker cable to the amplifier and speakers with the correct polarity and you're done. Unfortunately, many manufacturers of home cinema receivers put stumbling blocks out for the users in the form of specifications on the rear of the device and/or in the operating instructions. These usually look like the following (translations): Minimum connection impedance six ohm! Or, speaker impedance six to eight ohm. And what is the problem? There are hardly any six ohm and only a few eight ohm speakers available in Germany. Most of the speakers sold in Germany have a nominal impedance of four ohm. So theoretically, you shouldn't connect them to most of the receivers and amplifiers.

To explain why it is possible after all, we would like to briefly explain the electrical engineering principles: The impedance of a speaker is nothing other than its electrical resistance which it puts up against the flow of current.

• Low resistance = high current
• High resistance = low current

Important to know for operation with an amplifier is that the impedance is not the same for all frequencies but can, for example, change between 50 and 200 hertz by 50 percent. So it isn't entirely correct to speak of impedance for a speaker per se, rather one must always consider the behaviour across the entire range between 20 and 20,000 hertz. To still achieve a reasonable connection value for amplifiers (which, by the way, says nothing about the output impedance of the amplifier itself but rather only which impedances may be connected to it), the creators of the DIN Standard have applied the following stratagem: Only the minimum value of the impedance in the audible range is decisive for the nominal impedance value. This is where the most current flows and the amplifier is subjected to the highest load. Speakers with eight ohm nominal impedance may only exhibit a minimum of 6.4 ohm, and those with four ohm nominal impedance 3.2 ohm. Six ohm are not defined in the DIN (which is applied internationally), but one could use the above values to interpolate that they may exhibit a minimum of 4.8 ohm.

From the definition it is apparent that the nominal impedance is only a rough benchmark, because it says nothing about how the entire course of the impedance looks. No matter whether it only reaches less than 6.4 ohm at one point and is otherwise beyond that, or if the impedance moves close to 3.2 ohm across the entire range, but does not drop below that. The last speaker is surely much more stressful for the amplifier, but has just a nominal impedance of four ohm as the other higher ohm one.

Conventional speakers usually exhibit one to two minima in the bass range, and there is one frequently in the treble range. These minimum values are usually not especially broadband. Aside from the minima, the impedance is usually far higher than the nominal impedance. The amplifiers are really stressed in the bass range because firstly, this is where the most energy is for music and especially the home cinema sound, and secondly, they have to let the most current flow through the impedance minima here.

And lastly, the main reason why many manufacturers don't want four ohm speakers to be connected: In extreme cases - for deep frequencies of consistently 3.2 ohm - the amplifiers in multichannel operation become very hot. A lot of current also means a lot of power loss and thus at lot of waste heat. However, much has to come together before that happens - namely high performance for a longer period of time and setting up the device without sufficient ventilation.

But this extreme case is seldom met in practice. As mentioned above, most of the speakers are not as critical by far, and it is extremely rare to listen to an exorbitant volume for a longer period of time. That is why it is not a problem from a technical point of view to connect speakers with four ohm nominal impedance to all modern home cinema amplifiers and receivers.

However, there is one small catch: The question of warranty. Should a defect occur to the device - which doesn't even have to do anything with the speakers - and the manufacturer notices that four ohm speakers were connected despite the specifications to the contrary, he could refuse repairs due to improper use. As discussions with manufacturers and distributors have shown, this is highly unlikely because they are also aware of the problems.

And for purely legal reasons, Lautsprecher Teufel may not give you a warranty either that your amplifier or receiver will tolerate four ohm speakers. We can only pass along one experience: For several years, the listening tests of the trade magazines are done exclusively with four ohm speakers, and not a single defect has occurred as yet even though the devices are driven to their limits. Also, the performance of each device is usually measured at four and eight ohm irrespective of the specifications of the manufacturers, and the load here is also considerable. It has been a long time since measurement laboratories have seen failures due to to low load impedance.

There are still some special cases, which should be briefly mentioned: Amplifiers/receivers with impedance switches give cautious natures the possibility to stay on the safe side under all possible conditions, even with the warranty. The four ohm setting of the corresponding switch reduces the supply voltage of the power amplifiers so much that excessive heat cannot occur even under unfavourable circumstances. However, the maximum power is then reduced somewhat.

During the listening tests of the trade magazine, these devices are always switched to the "eight ohm" setting to tease out the maximum performance reserves. A defect here has yet to occur. When choosing devices, take a close look because there are devices that only permit speakers with a minimum of six ohm despite the impedance selector switch, like the Pioneer VSX-D2011, for example. This is remarkable in another respect: It possesses a THXSelect license. This license is only issued if certain measured values are complied with that are determined at four ohm for at least the front and centre speakers.

If the THX laboratory had proceeded according to manufacturer's specifications, the VSX-D2011 would never have received a licence, as it would not have been permitted to perform the necessary measurements. By the way: this is also the case for other THX Select devices. But you needn't worry here: The THX logo not only offers additional security, but also a good lever should a manufacturer once refuse a warranty.

The AUDIOVISION TIP

Overheating is the main problem that can occur through the combination of four ohm speakers with power amplifiers that are not released for this.
Therefore, in case of doubt:

• Always set up the AV Receiver or amplifier in well ventilated places and never in a closed housing or close to the heater.

• Occasionally check the temperature of the device.

• Reroute the bass elements via set-up at the subwoofer, if possible.
What's behind THX Optimode?
THX Optimode is the latest development of the THX Digital Mastering Program consisting of a series of tests that enable every home cinema user to adjust his system exactly in picture and sound to the Optimode DVD currently in the DVD player.

The first DVD that supported the new feature was "Fight Club" in the Special Edition by 20th Century Fox (NTSC version). The offer has been continually expanded in the meantime.

The tests, which can be played on NTSC as well as PAL DVDs, consist of video tests that are helpful in optimally setting and configuring the TV or video projector, as well as audio tests that guarantee that the sound system is configured perfectly.

The special thing about these tests is the fact that the measuring signals are identical to the reference signals that were used during the final mixing of the relevant DVD. The home cinema system can therefore be co-ordinated accurately and individually to every single DVD with THX Optimode.

The goal of the entire procedure is that the sound and particularly the picture should appear in the home cinema exactly as the producer imagined. Let's assume the film producer wanted to create a certain mood in the film using specific colouring; this only works in the home cinema if the screen at home is just as co-ordinated as in the studio. Thanks to THX Optimode, that is guaranteed as far as possible.

Operating THX Optimode is just as easy: The software on the DVD includes all of the tests. Individually, these are video tests to set the contrast, brightness, colour, colouring, control of the correct ratio of picture length to picture width and the possibility to test the general qualities of the monitor.

In addition, there are audio tests for the phases of the speakers, connection of the speakers and the cut-off frequency of the LFE (subwoofer channel). Some tests will clearly show when it is necessary to consult a specialist for the settings.
I would like to connect the appliance to a record player, is that possible?
In principle, yes.

However, for a record player an additional phono preamplifier is required - these are available from specialist retailers for around €50.
What are the technical requirements for an AV receiver to function with RearStation 4?
The AV receiver must be able to send signals to the rear channels via a pair of cinch terminals. Generally these terminals will be identified as Side, Rear, or Left/Right. It is often also possible to "activate" channels on specific terminals by means of the AV receiver menu.
The RAMPA insert at the bottom of the speaker sometimes is turned out with the tamping screw. What can I do about that?
Unscrew the tamping screw from the Rampa insert and screw the Rampa insert back into the bottom of the speaker.
What is the advantage of bi-amping/bi-wiring?
Bi-amping means that the speaker can be operated by two amplifiers at the same time, or by a bi-amping-capable AV receiver. This enables the different chassis (for the treble mid-tone and bass range) to be individually supplied with one signal. Among other things, this could increase the sound performance of a speaker.

Bi-wiring states that the corresponding speaker can be controlled at the same time with two different speaker cables, meaning via separated input sockets for the treble and mid-tone range on one hand, and for the bass range of the frequency switch on the other. This could improve the sound even more. Bi-wiring is the prerequisite for bi-amping.
My subwoofer is humming. What can I do?
This hum can be caused by the connected devices or disruptions in your electricity current. Please do a test to see which it is.

1. Remove the RCA cable from the input on the subwoofer. If the hum is no longer heard, go to point B. Otherwise, follow point A.

A. Attach the net cable of the subwoofer to another electricity outlet (i.e. Kitchen/Bathroom/Bedroom). If the subwoofer still hums, get in contact with our Support team.

Should the hum no longer be there, the disruption was a problem in your power supply, which can, for instance, be caused by dimmers or chargers. To find out where the disruption is, unplug all your devices and work back from there. As soon as the hum is heard, you now know your source of the disruption.

B. In your case, the "ground hum" is responsible for the disruption. Please proceed as follows to discover your source.

  • Disconnect the cable or satellite port from the TV Receiver and check if the hum disappears or not. If it does, you can use a sheath current filter for the cable outlet to prevent this. For example, the sheath current filter AC 9022 ED. If you have a satellite connection, connect the Satellite Receiver to the optical cable playback source - Teufel Optical Digital Cable

  • If this reason can be excluded, separate all devices from the AV Receiver one at a time until the hum stops. The last connected device is then your hum source and should be separated from the others using a galvanic separation filter (found in a retail shop)

  • If this doesn't work, get in contact with us once again so that we can give an individual, helpful response.
Will an active subwoofer only run in 5.1 mode or also in stereo mode?
Thanks to the speaker set-up/bass management integrated in the home cinema receivers/amplifiers, the subwoofer functions in stereo, Dolby Surround and digital mode.

The corresponding setting in the speaker set-up must be adjusted individually for each source for many receivers, however, e.g. for CD playback only front without woofer, and front speakers plus woofer for Dolby Surround video playback.
Why doesn't my active subwoofer switch on automatically?
Some AV Receivers/amplifiers issue the bass signals via the subwoofer pre-amplifier output so quietly that the subwoofer does not start automatically.

To make sure the subwoofer switches on and off correctly in automatic mode, (to be selected on the corresponding switch of the subwoofer, such as "Auto / On / Off"), we recommend turning the level control on the subwoofer to 1/3 or perhaps to 1/2 and increasing the output level for the sub in the receiver's speaker set-up – sometimes up to the maximum (+10 dB or +12 dB). The subwoofer should then work perfectly.

The maximum position of the output level in the speaker set-up of the AV Receiver is obligatory for some of our models (e.g. the Concept S subwoofer).
How do I connect my fully active Teufel system to an AV Receiver?
Although designed to be fully active, the Teufel set is also partially active in conjunction with an AV Receiver.

You can connect it like a standard speaker system: the five satellites via speaker cable to the corresponding speaker outputs front R/L, rear R/L and centre of the AV Receiver/amplifier and the subwoofer from the front R input via a mono-RCA cable to the Sub Out output on the A/V Receiver/amplifier.

Please note:
The auto on/standby switch only responds when the front R input is being used! The subwoofer also receives the full subwoofer signal via this channel.

If the AV Receiver/amplifier has preamplifier outputs for all channels (front R/L, rear R/L, centre and subwoofer), the Teufel set can also be connected via three RCA cable pairs to the subwoofer and the satellites via speaker cables to the subwoofer. However, we recommend using the first version.
What is a ground hum?
The hum (50 Hz) comes from the 220 volt supply network and is caused by current power flows through the protective conductor. These so-called "ground hums" is caused when you connect two devices that are already grounded on the protective conductor (subwoofer) or the antennae cable (AV Receiver) to the subwoofer cable.

Solution:
Separate the direct connection by a grounding filter for the antennae cable that is created for it - for instance, the Teufel modell sheath current filter AC 9022 ED. Alternatively, you can use a galvanic separation filter that is looped into the connection between the subwoofer and AV Receiver.

The hum disappears if the antennae cable is separated from the Receiver/Tuner/TV. First try the grounding filter, otherwise the galvanic separation filter.
Where is the optimal place for the subwoofer of my Lautsprecher Teufel Surround System in a 5.1/6.1/7.1 configuration?
The location of a subwoofer with a recommended cut-off frequency of under/equal to 120 Hz can be freely selected and does not affect the other speakers.

Placement within the straight line between both front satellites is ideal - but not precisely in the corner of the room because certain frequency components could be unpleasantly excessive when played back.
How do I determine the right phase setting of the subwoofer?
By setting the phase, you can affect the point at which the membrane of the subwoofer bass speaker moves to the front. This setting makes it possible to optimally adjust the subwoofer to the satellites.

The membranes of the satellites should move to the front at the same time as the membrane of the subwoofer bass speaker, because all speakers of the system must vibrate in phase for optimal playback. This means that (provided the connection has the correct polarity) all drivers must move in one direction when the three front speakers receive a pulse (towards the outside or towards the inside).

If the subwoofer is in line with the front speakers, its bass speaker should have the same direction of movement (phase) - the controller on the woofer is set to "0". If the subwoofer is not between the front speakers, but is to the side of or even behind the listening location, its phase length will not match that of the front speakers. That is why the phase of the subwoofer must be changed in such cases.

So much for the theory. In practice, this means: Listen to a loud piece of music with heavy basses and ask a second person to change the phase during playback. The correct setting of the phase switch depends on where the subwoofer is positioned in the room. The position where the bass playback (above all the upper bass range) sounds the fullest is the correct position. Have fun trying it out!
What is the use of the on/off automatic switch ("Auto On/Off") of the active subwoofer?
The On/Off switch is a power-saving standby switch. The switch must be set to "On" or "1" to activate the standby. The subwoofer is activated as soon as it receives a strong bass signal. After approx. ten to twenty minutes of no signal, or only after receiving a very weak signal, it automatically switches to the standby function.

Even though the LED is still illuminated, the subwoofer is in standby mode. This function can be easily checked by slowly increasing the volume at the receiver/amplifier. You will hear a quiet popping noise when the subwoofer activates itself as of a certain level.
What happens to the power amplifiers of the subwoofer if I don't connect the satellites?
As soon as the satellites are connected to the subwoofer and not to the AV Receiver/amplifier, the performance of the 6 or 8-channel power amplifier is distributed to the subwoofer and to the satellites.

If the satellites are not connected directly to the subwoofer but to the AV Receiver/amplifier via speaker cable instead, the subwoofer performance will increase somewhat; the power amplifiers for the satellites have no function. This enables the subwoofer and satellites to play even more dynamically than if the subwoofer still had to provide the satellites with performance.

The technical background: The subwoofer has a large transformer with a specific wattage. This performance is either distributed to the five satellites and the subwoofer, or you receive a higher performance only for the subwoofer.
How can I connect an additional active subwoofer?
If your receiver has only one subwoofer output ("Sub Out"), you only need a monocinch cable, which is then connected from the receiver to the "Sub In" of the subwoofer. With two subwoofer outputs, you can order a so-called Y-adapter from the Teufel accessories page, which has a cinch plug on one side and two cinch (RCA) sockets on the other. Connect the plug to the subwoofer "Pre Out" on the AV receiver/amplifier and connect the mono cinch cable to the two subwoofers.

If the cabling method is easier for you, then you can alternatively connect one subwoofer to the other. You will need two mono cinch cables - one to connect the subwoofer "Pre Out" on the AV receiver/amplifier to the left line-in input of the first subwoofer, and the other to connect the left line-out output of the first subwoofer to the left line-in input of the second subwoofer.
How is the wattage of a subwoofer with respect to the sine wave and pulse/music performance?
Mono subwoofer:

The wattage (e.g. "360 W") printed on the rear of the subwoofer near the mains plug designates the ability of the power amplifier "to pull" a maximum power rating in the specified range at the moment of switching on (those 360 watt stated as an example).

Consequently, the wattage must correspond to at least the sine wave output of the amplifier, as this sine wave output must be permanently available which the power pack must provide as well.

The pulse/music performance of the amplifier, on the other hand, can exceed the wattage, because the short pulses are buffered additionally by the capacitors in the power pack and are not achieved solely through the performance of the power pack.

Multi-channel subwoofer:

The wattage for a multi-channel subwoofer can also be below the sine wave output, as the specified sine wave output is not requested from every channel at the same time.

For a 5 x 100 watt sinus power amplifier, for example, each of the five channels is able to implement 100 watt sine. However, not all five channels at the same time! This is also unnecessary, as the same signal is never transmitted across all five channels at the same time, thus requesting the same high sine wave output per channel.

That is why the wattage may be, e.g. 300 watt, even if the sine wave output exhibits 5 x 100 watt (= 500 watt).
What are the volume switches for?
The sound of the speaker always depends on the room where it is located.

The volume of the active subwoofer can be controlled so that you can adapt the relationship between the active bass and treble / mid tones to suit the room.

Use your own senses to judge which settings sound best in your room. This switch is especially useful in stereo mode. On the other hand, multichannel amplifiers often have technologies that adjust the subwoofer volume - so when using a multichannel amplifier the controller should first be set at 0dB.
What is room resonance frequency?
Room resonance frequency (other terms: room modes, standing waves, resonance frequency) is the frequency at which the vibrations of a voice, a musical instrument or a signal played back over the hi-fi/home cinema system is amplified unnaturally, because the vibrations build up between the walls as well as the floor and ceiling.

It is calculated of the sound velocity divided by 2 and divided by the room length [ 340 m/s: 2 : 6 m = 28.3 Hz (=1/s) ] or, more simply: 170 divided by the room dimension (length, width or height). The greatest distance between two parallel walls is taken as first standard value. For a room of 4 x 6 metres, this would be 6 metres. Strictly speaking, you would have to calculate the room resonance frequency for further parallel walls (for the 4 metres and for the ceiling height).

Overlaying resonances are also possible if the room dimensions are very close to each other. (2.8 metres high, 3 metres wide and 5.6 metres long). The resonance at 2.8 metres is repeated as multiple (times 2) at 5.6 metres length, the resonance of the 3 metres width is close to the resonance of 2.8 metres. It would resonate strongly here at 30 Hz, 56 Hz, 60 Hz and 120/112 Hz.

Phenomena of resonance frequencies:

• For example, a man with a deep voice speaks in a very small room (2 by 2 metres, 85 Hz). The voice appears to have more emphasis than in another room or out of doors. As soon as a woman speaks, the voice will sound just the same as in another room.

• The voice of a woman or that of a small child will cause glass to shatter. The voice strikes exactly the tone that corresponds to the resonant frequency of the glass. The glass resonates so strongly that it shatters (refer to the movie "The Tin Drum").

• A group of soldiers march across a bridge in cadence. The equal movement causes the bridge to vibrate so much that it collapses. That is why no one marches across bridges in cadence.
