Product Information

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.
