That rocks – the new M FOUR DSP
The M FOUR DSP is more than “just” another four-channel amplifier – rather, despite its small dimensions, you are dealing with a powerful control center that has not less than a total of ten processed DSP channels. In addition, the amplifier delivers plentiful output power with generously 100 Watts RMS per channel into both 4 Ohms and 2 Ohms load.
Finally its awesome price performance ratio in combination with the fantastic feature set will ensure bright eyes.
Tonally absolutely HELIX!
Compromises in terms of sound quality have no place in a HELIX product – and that’s why the M FOUR DSP is equipped with all the finesse for perfect sound. Of course, excellent and separate AD and DA converters are just as natural as on the DSP circuit board, which is completely manufactured in Germany, you will find only excellent, separate AD and DA converters as well as an extremely powerful DSP from Analog Devices. In addition, the six pre-amplifier outputs with 6 Volts output voltage provide more than enough level to drive any additional amplifier.
Even the internal amplifier section of the M FOUR DSP is extremely variable – it can either be operated in 4-channel mode or, thanks to its bridging capability, can also be configured as a 3-channel or even 2-channel amplifier.
But that’s not all – in connection with the six pre-amplifier outputs, the sound system can be expanded in a diverse manner and upgraded to up to 10 channels.
In combination with other amplifiers of the M series (M ONE X, M ONE, M FOUR or M SIX), there are more than enough possibilities to expand the number of power channels.
This makes complex, yet affordable and, above all, space-saving multi-channel systems with enormous performance possible.
Virtual Channel Processing – that´s how signal routing works today
Many DSP channels need to be managed and configured properly – so there was no question that the M FOUR DSP is also equipped with Audiotec Fischer’s innovative virtual channel processing.
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”.
The plus in speed – thanks to ACO
Faster is better – the particularly powerful 32 Bit ACO platform takes over all control tasks and ensures significantly more speed, 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 that already include an “ex works” sound setup.
Compact, cool and absolutely practical
Despite its vast range of functions and huge output power the M FOUR DSP presents itself in the same classic, compact HELIX design with distinctive lines like a HELIX M FOUR or M ONE. Thanks to its Class D amplifier technology, it keeps a “cool head” even at full power. And thanks to features such as start-stop capability, ADEP.3 circuit and power save mode, it is also ideally equipped for the now everyday challenges of OEM integration.
