HELIX D FOUR
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.
