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!

Helix C FOUR
Audiophile sound quality combined with impressive output power
The C FOUR is a high-end 4-channel amplifier that has been designed down to the last detail for ultimate sound quality. Audiotec Fischer’s proprietary ultra low-noise and ultra low-distortion Class A driver stage feeds a total of 32 hand-selected MOSFET power transistors, resulting in an incredible damping factor of 1,000 for relentless control of every loudspeaker. The intelligent regulation of the power supply assures stable conditions for the output stages and therefore phenomenal output power independent of the cars battery voltage.
In combination with the optionally available digital input module HDM 2, the C FOUR demonstrates the perfect transition to the digital era. The HDM 2 accepts digital audio signals up to 96 kHz sampling rate via its two optical inputs followed by cutting-edge BurrBrown D/A converters with 32 Bit resolution that transform the signals back to the analog domain. Therefore the C FOUR is absolutely future-proof and perfectly prepared for the combination with our digital signal processors. -
Helix C ONE
The sound power house – extremely powerful and stunning sound quality
The C ONE is a high-end 1-channel amplifier that is able to drive even powerful subwoofers to the max. The ultra low-noise and ultra low-distortion Class A driver stage feeds a total of 32 hand-selected MOSFET power transistors, resulting in an incredible damping factor of 1,000 for relentless control of every loudspeaker.
Additionally the intelligent regulation of the power supply assures stable conditions for the output stages and therefore phenomenal output power that is almost independent of the cars battery voltage. And for even more output power, two C ONE amplifiers can be combined to one single powerhouse – thanks to the TwinPower Link.
Despite its impressive output power, the C ONE is by no means a pure subwoofer amplifier. Thanks to an extended frequency response up to 80 kHz and an architecture that has been designed down to the last detail for ultimate sound quality, the C ONE is also a perfect buddy for heavy-duty mid-woofers in audiophile system concepts.
In combination with the optionally available digital input module HDM 1, the C ONE demonstrates the perfect transition to the digital era. The HDM 1 accepts digital audio signals up to 96 kHz sampling rate via its optical input followed by cutting-edge BurrBrown D/A converters with 32 Bit resolution that transform the signals back to the analog domain. Therefore the C ONE is absolutely future-proof and perfectly prepared for the combination with our digital signal processors.
