HELIX 4-Channel Amplifier with Integrated Digital 10-Channel Signal Processor

HELIX M FOUR DSP 

That rocks - the new M FOUR DSP

The M FOUR DSP only presents itself at first glance as a four-channel amplifier - in fact, despite its small dimensions, you are dealing with a powerful control centre that has no less than a total of ten processed DSP channels. And more than enough power, because 100 watts of continuous power per channel, both at 4 ohms and 2 ohms, is casually shaken by this amplifier. In addition, there is a fantastic equipment package, which will ensure bright eyes at the latest when it comes to the price-performance ratio.




Sonically through and through HELIX!


Sound compromises have no place in a HELIX product - and that is why the M FOUR DSP is equipped with all the finesse for the perfect sound. Separate AD and DA converters of the latest generation from Asahi Kasei with a native resolution of 32 bits are just as natural on the DSP circuit board manufactured in Germany as the use of 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 control any output stage.




Virtual Channel Processing - this is 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 was also equipped with Audiotec Fischer's innovative Virtual Channel Processing.

The adaptation to modern OE sound systems via an increasing number of signal inputs makes an increasingly complex signal routing in the amplifier inevitable. Especially when several input signals are mixed together and then broken down again into multi-path systems, conventional routing concepts quickly reach their limits in terms of implementation and usability. The multi-level "Virtual Channel Processing" makes it possible, in conjunction with the recognized user-friendly DSP PC-Tool software, to easily map even highly complex system configurations and to use the proprietary FX sound features such as "RealCenter" or "Augmented Bass Processing" can be freely assigned.




The plus in speed - thanks to ACO




Faster is better - the particularly powerful 32-bit ACO platform takes overall control tasks and ensures significantly more speed, especially for data communication with our DSP PC-Tool software, but also for lightning-fast switching between the up to ten possible sound setups. But ACO offers much more - fantastic sound effects such as Augmented Bass Processing, StageXpander or RealCenter are implemented as well as a channel-separated input EQ including an input signal analyzer (ISA) for easy analysis and compensation of the input signals from OE radios that already have a sound ex-works -Setup includes.




Compact, cool and very practical

Despite the enormous range of functions and the full output power, the M FOUR DSP in the typical HELIX outfit with clear lines is just as fantastically compact as an M FOUR or 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 associated with integration in OEM systems.
