The HELIX M SIX DSP is a 6-channel Class D car audio amplifier with an integrated digital signal processor delivering 100 Watts RMS per channel into 4 and 2 Ohm loads and up to 130 Watts RMS peak per channel. The unit provides six speaker outputs, bridgeable channels, four high-level inputs, six RCA inputs and four RCA line outputs with up to 6 Volts output voltage for connecting additional amplifiers.

Internally the M SIX DSP uses high-quality A/D and D/A converters and a 64-bit fixed point audio DSP with Virtual Channel Processing and a 32-bit ACO coprocessor for fast control and advanced features such as ISA InputEQ, Augmented Bass Processing and RealCenter. The DSP board is manufactured in Germany and the amplifier supports start-stop, ADEP.3 circuit, power save mode and multiple channel configurations for flexible system integration.
