An ultra-compact high definition AV controller for multi-channel active subwoofers or in combination with the Teufel AmpStation. There are three HDMI inputs, one HDMI output, three digital audio inputs (2 x coaxial, 1 x optical) and three analogue stereo inputs on the back of the unit, which allow for connection with a wide range of audio and video devices.

The 3D-compatible device includes a decoder for DTS HD Masters, Dolby True HD, DTS, Dolby Digital, Dolby Pro Logic and many other formats.

The Decoderstation 7 can be connected to a multi-channel active subwoofer or to the amp station via a 5.1 analogue output. The system package is completed with further features such as a headphone connection, FM/AM radio with RDS function, a remote control, and a clearly legible, dimmable display as well as extensive setting options with on-screen user guidance.

The new AmpStation proves that you don’t need a big amp to enjoy full, room-filling sound. This 8 channel high-end amplifier with compact dimensions is the perfect accompaniment for Teufel stereo and home cinema speakers.

Teufel built 8 individual 100-Watt amplification modules into a small enclosure measuring just 270 x 65 x 250 mm for a high-performance amplifier that can also be conveniently placed – or even concealed - in any living room. Most incredibly, the AmpStation’s performance can extend even beyond the room it’s placed in. Used with a 5.1 setup, the AmpStation can still power an additional pair of stereo speakers in another room.

Based on the newest class D amplification technology from Texas Instruments, the AmpStation boasts impressive technical data. HD audio signals such as Dolby Digital True HD and DTS HD Master are perfectly processed by the little system. 
800 Watts of pure power
The AmpStation works as a pure power amplifier, which can supply up to 8 individual loudspeakers with 100-Watt output power each (at 4 Ohms). That's enough power for the most demanding home cinema and music requirements, even in huge rooms with full-range floor-standing speakers. The nimble little AmpStation reacts promptly to quick changes in volume levels for playback that is finely nuanced and lively. And it knows how to coax the warmest and most realistic sound from your Hi-Fi speakers and surround sound systems. Alternatively, the AmpStation can also fuel a pair of stereo speakers in 5.1 mode, for example in another room.
A top-class digital amplifier
Class-D technology from Texas Instruments (TAS5611) is what makes the AmpStation’s extremely powerful performance from such a small enclosure possible. But the AmpStation’s sophisticated technology not only ensures high levels: Very low levels of distortion - just 0.03% (THD+N > 1 watt) - and an incredible signal-to-noise ratio (-105 dB) are all part of the package. The AmpStation’s frequency range extends from 10 to 40,000 Hz and is highly linear for realistic playback from all kinds of music and soundtracks.
High-quality materials
The AmpStation’s workmanship is every bit as premium as the sound it generates. A massive front plate made from aluminium and gold-plated connection sockets aesthetically underpin the device’s acoustic performance. The electronics within are situated on a vibration-reducing steel plate.

The AmpStation has the exact same width as the DecoderStation 6 or 7. This makes it easy to stack the two devices for use together.
Looks as good as it sounds
In spite of the AmpStation’s cutting-edge technology, there was one old school feature we couldn’t resist - analogue VU meters. Both eye-catching meters provide information about the level ratios of the individual channels.
No fans, no noise
The AmpStation’s cleverly designed cooling system allows the device to do away with integrated fans – components that not only take up a lot of space, but which also make a good deal of noise. While larger amps and A/V receivers drone away, the compact little Teufel stays cool and quiet – even when pushed to its maximum performance levels. The side ventilation also make it possible to place the AmpStation inside a piece of furniture.
High-quality amplifier
The AmpStation has enough power and high-quality sound technology at its disposal to elevate previous and current Teufel loudspeaker systems to a new acoustic level. Extreme transparency, distortion-free dynamics and authentic playback is what you can expect.
Perfect match
Not least because of the same physical form, the AmpStation is an ideal partner for the DecoderStation 7. Technically, of course, they fit together perfectly, because the power amplifier was deliberately designed by Teufel for exactly this connection. Together they form a wonderful combination: an AV pre-amplifier and high-end AV power amplifier at an unrivalled price.

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.
Can I operate Teufel speakers with an amplifier with 6 ohm outputs?
Without problem!

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.
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.
Can I also connect a 6.1 speaker system to a 7.1 AV Receiver?
No problem.

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.
Can I order the Teufel speakers in different colours than those offered?
To realise the very reasonable sales prices usual for Teufel, it is not possible to offer the speakers in a multitude of housing designs.

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.
