Overview of our technologies
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.
Chromecast built-in – formerly Google Cast – is a technology that makes it possible to stream music service apps to Wi-Fi speakers or receivers. Streaming can be controlled via an extensive selection of Chromecast-supporting apps installed on smartphones, tablets or laptops. The Chrome browser can also be used directly for the control.
Conventional D/A converter methods reduce interference pulses during D/A conversion, but cannot completely eliminate them. By contrast, the VLSC (Vector Linear Shaping Circuitry) technology developed by ONKYO effectively eliminates interference components. As a result, you get virtually true-to-original analogue signals from your digital sources that reveal even the most subtle audio features.
Loudspeakers with THX certification guarantee the following:
- 3 identically constructed & tuned front loudspeakers for homogenous and precise sound reproduction
- Maximum noise reduction at high volumes for a consistently clean and detailed tone
- An almost completely linear frequency response for extremely accurate sound reproduction
- Wide dispersion along a broad horizon that reaches more listeners
- Distortion-free high volumes for authentic sound reproduction
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.

This circumstance would drive up the production and storage costs, which would result in a significantly more expensive sales price.
A paint shop in your vicinity will surely be able to repaint the speaker housing to your preferred colour without loss of warranty - after expiry of the eight-week right of return.
Solution: Change the transmission channel on your WLAN router. We recommend channel 11.
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.
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).
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.
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.
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.
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:
• 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.
• 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
• 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.
• 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.
• 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.
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.
The fact that some amplifier manufacturers give corresponding information is founded in the VDE standard. To comply with this standard, the devices may not become hotter than 40°C above room temperature so that no one is injured when touching the amplifier.
These 40°C are only reached in the threshold range, meaning for very great volumes for a longer period of time. There is no danger of overloading the amplifier during normal operation. The higher temperature that occurs when connecting 4 ohm speakers will not damage the device in any way. Therefore you can connect 4 ohm speakers without reservations.
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.
However, for a record player an additional phono preamplifier is required - these are available from specialist retailers for around €50.
A 7.1 AV Receiver merely provides the possibility of utilising a 7.1 speaker system; it is not, however, a mandatory necessity.
That is why you can only use a 6.1 speaker system with the 7.1 AV Receiver. In the "Speaker Set-up" menu of the receiver, you frequently only need to specify which of the two channels will be addressed as rear centre.
