Description

The king of connectivity
That has never existed before – 12 highlevel inputs, 6 Cinch inputs, 14 DSP channels, 12 output stages with up to 160 RMS at 2 Ohms combined in an ultra-compact housing that has the footprint of just two envelopes. The new V TWELVE DSP is unmistakeably a technological milestone and the problem solver par excellence when it comes to upgrading multichannel premium sound systems in today’s vehicles.

Connectivity redefined
What to do if a vehicle is already equipped with a premium sound system ex works, whose amplifier often already has more than 10 channels?  In many cases, a replacement is no longer possible, so that only an amplifier with the same number of highlevel inputs can be considered for upgrading the system. The V TWELVE DSP is the first amplifier worldwide that offers 12 highlevel inputs and just as many amplifier channels, a digital input and a HEC slot. The integrated DSP can handle this easily, since it comes with the incredible number of fourteen (14!) separate channels.

Virtual Channel Processing – this is 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. 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”. But thanks to its enormous number of channels, the V TWELVE DSP is also a prime example for applications in which a 1 to 1 routing (IOR) makes sense.

The plus in speed – thanks to ACO
Such a huge number of channels requires ultra-fast hardware – Audiotec Fischer’s proprietary 32 Bit ACO platform takes over all control tasks and ensures exceptional speed especially for data communication with our DSP PC-Tool software, but also for lightning-fast switching between up to ten possible sound setups. The fantastic sound effects associated with the ACO platform such as Augmented Bass Processing, StageXpander or RealCenter are just as natural with the V TWELVE DSP as a 12-channel input EQ including our Input Signal Analyzer (ISA) for easy analysis and compensation of the input signals from OE radios.

Sound quality without any compromises
Separate AD and DA converters of the latest generation from Asahi Kasei with a native resolution of 32 Bit ensure optimal sound performance, best possible signal-to-noise ratio and minimal distortion. Concerns that the abundance of audio channels and the extremely dense design could have an impact on the sound quality are completely out of place for a HELIX product.

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.
