HELIX V EIGHT DSP MK2

Description

The new multi-tool for professionals
The small addition in the product name makes the big difference – the V EIGHT DSP MK2 is the logical evolution of its already more than impressive predecessor. Same look as before but in the inside Audiotec Fischer brought in all of his expertise and substantially optimized the hardware.  The result is an 8-channel amplifier with ten processed DSP channels that is unrivalled in many ways.

Extra speed – thanks to ACO
Faster is better – the particularly powerful 32 Bit ACO platform takes over all control tasks and ensures the decisive speed increase, especially for data communication with our DSP PC-Tool software but also for the lightning-fast switching between up to ten sound setups.  But ACO offers much more – fantastic sound effects such as Augmented Bass Processing or RealCenter are implemented as well as a channel-separated Input EQ including the Input Signal Analyzer (ISA) for easy analysis and compensation of input signals of OE radios.

New signal converters for optimized sound quality
Instead of a combined codec, the new V EIGHT DSP MK2 uses separate AD and DA converters of the latest generation from Asahi Kasei with a native resolution of 32 Bit. This ensures maximum signal resolution in the entire signal path from input to output – and thus also guarantees optimal sound quality.

Virtual Channel Processing – that´s how signal routing works today
The adaptation to modern OE sound systems via an increasing number of inputs has a significant impact on the complexity of the signal routing inside the amplifier. Especially when several input signals are mixed together and then split again into multi-way systems, conventional routing concepts quickly reach their limits, both in terms of implementation and usability.  Audiotec Fischer’s new multi-stage “Virtual Channel Processing”, in conjunction with the recognized user-friendly DSP PC-Tool software makes it easy to realize even highly complex system configurations. Besides, it allows to freely assign our proprietary FX sound features such as “RealCenter” or “Augmented Bass Processing”.

Maximum connectivity
More and more cars are equipped with factory-provided sound systems.  Most of them contain a multi-channel amplifier that cannot be replaced by another amplifier. The adaptation to such a configuration not only requires a lot of input channels but also a particularly wide adjustment range for the input sensitivity. Therefore, the V EIGHT DSP MK2 offers both six RCA / Cinch inputs and eight highlevel inputs with a maximum input voltage from 4 V to 32 V.
In addition the V EIGHT DSP is of course also equipped with the latest generation ADEP.3 circuit.

Power pack in a noble design
Despite its further increased feature set and up to 160 Watts RMS output power per channel (@ 2 Ohms) the V EIGHT DSP MK2 presents itself in the classic, clean HELIX design which provides ideal preconditions for a quick and easy integration.
High-tech performance could hardly be more noble and elegant!

DSP Features

RealCenter
The “RealCenter” feature is an algorithm, developed by Audiotec Fischer, that emphasizes the music information which is present in both the left and right front channel to create an unique center signal. In contrast to common procedures, in which only the channels are summed up, the intensity of the center signal is also dynamically controlled by the stereophonic informational content of the left and right channel.
Sounds complicated but this effect is astonishing: That means if solely the left or right channel delivers an audio signal, the center channel will not reproduce a signal. In the case of common algorithms, the volume level of the center channel is only reduced by 6 dB (= half volume level). Audiotec Fischer’s “RealCenter” allows a unique, broadened sound staging for both driver and co-driver at the same time! Therefore, the disadvantages of a conventional center channel, such as an intrusive, small sound stage, are things of the past.

Augmented Bass Processing
Audiotec Fischer’s proprietary “Augmented Bass Processing”, consisting of the two revolutionary sound features “Dynamic Bass Enhancement” and “SubXpander”, has been especially developed to dramatically improve the bass reproduction of subwoofers.
The “Dynamic Bass Enhancement” ingeniously combines maximum deep bass and highest sound pressure – regardless of the music style or the tone controls in the head unit. Depending on the input signal, the “Dynamic Bass Enhancement” gains the lower frequency range and varies the cut-off frequency of the subsonic filter. The result is a significantly more powerful and deeper bass response at low and medium volume levels without the risk of overloading the subwoofer neither mechanically nor electrically at high volume levels. It is simply fascinating which bass performance is suddenly possible.
If you want an even lower and “darker” bass reproduction, the “SubXpander” can be additionally activated. Therefore, subharmonic tones are added to the fundamental tones in the frequency range between 50 and 100 Hz.

StageXpander
Depending on the speaker arrangement in the vehicle, a more or less wide stereo sound stage can be created on the front seats. A center speaker may limit the spatial reproduction of the music additionally. This is where Audiotec Fischer’s new “StageXpander” comes into play – a sound feature which seems to break the acoustic limitations and thus allows to create a way broader stereo base without negatively affecting the precision of the localization of voices or instruments!
The effect can be adjusted according to your personal preferences in four steps.

ClarityXpander
You are looking for more transparency and substance in the treble reproduction? With the “ClarityXpander” Audiotec Fischer is now offering the right tool. Properly adjusted (and therefore selectable in three steps) the feature adds additional harmonics in the upper frequency range – this is especially useful if the original speakers lack some brilliance in the treble response. The extra treble-kick is not only available for the two front channels but also separately adjustable for the center channel. Even better – the center channel allows to activate an automatic and dynamic control so that music with “loads” of treble doesn’t fatigue your hearing.
