Helix – D Four

  • 4-channel high- and lowlevel input
  • Smart highlevel input with ADEP circuit (Advanced Diagnostics Error Protection) and Auto Turn-On function
  • Fully active crossover with highpass, lowpass, bandpass and bass boost
  • Extremely stable MOSFET power supply
  • “Input mode” switch for flexible input signal routing
  • Highlevel input sensitivity up to 14 Volts max.
  • Cable remote control for volume adjustment of the channels C & D optionally available
  • Massive aluminum heatsink for best cooling conditions


The new entry into the HELIX world! The amplifiers of the D series are solely modest with respect to pricing. Everything else is thoroughly pure HELIX quality without any compromises. Loads of power, excellent measurement data and a whole bunch of features ensure a pristine and crispy sound experience!

Absolutely nothing has been missed for powerful sound reproduction – the active crossover with highpass filter, lowpass filter, bandpass and bass boost are equally as self-evident as the intelligent highlevel input that incorporates Audiotec Fischer´s proprietary ADEP circuit. It is even possible to add an optional volume remote control for the amp channels C and D which is very useful if those outputs are firing a subwoofer.

The elegant design not only states right from the beginning the amp's heritage but also allows an easy integration into your car thanks to its compact dimensions. That is sound-tuning at its best!

Smart highlevel input

The latest generation of OE car radios incorporates sophisticated possibilities of diagnosing the connected speakers. If a common amplifier will be hooked up failure messages and loss of specific features (e.g. fader function) quite often appears – but not with the D FOUR.
The new ADEP circuit (Advanced Diagnostics Error Protection) avoids all these problems without loading the speaker outputs of the OE radio during high volumes unnecessarily.
