The M series of amplifiers is an exclusive, extremely compact and clean design with a subtly illuminated HELIX logo. Thanks to the latest class D technology, the amplifiers are compact and the exceptional efficiency guarantees low heat dissipation, which allows trouble-free installation in many places of the vehicle. M FOUR DSP is more than just another four-channel amplifier, it is also a powerful control center with 10 DSP channels! There is no room for compromise on sound quality, so the DSP section is entirely Made in Germany and features a powerful Analog Devices computing chip and separate AC and CA converters. The internal section of the M FOUR DSP amplifier can operate in 4-channel mode or, thanks to the possibility of bridging, as a 3-channel or even 2-channel amplifier. In addition, six preamplifier outputs with an output voltage of 6V will provide more than enough drive level for any external amplifiers. All this makes it possible to expand the sound system up to 10 channels. In combination with other M series amplifiers (M ONE, M ONE X, M FOUR, M SIX), there is a whole range of possibilities for extending the number of channels and therefore configuring inexpensive but above all space-saving multi-channel audio systems with really good performance. The audio processor works under the control of the 32-bit ACO platform, which takes over all control tasks and provides much faster operation, even instantly switching between ten preset memories, but also during communication with the DSP PC-Tool software. ACO also offers the necessary tools to implement the most complex configurations. Professional options, such as measurement and correction of input signal parameters (ISA and Input EQ), which are necessary to compensate for corrections introduced by the factory system, and proprietary special functions (FX), such as "RealCenter" or "Augmented Bass Pocessing". The large number of DSP channels also requires adequate management capabilities, so it was clear from the outset that the M FOUR DSP must be equipped with “Virtual Channel Processing” - an innovative, multi-stage signal processing system developed by Audiotec Fischer.
