Match PP 86DSP
The powerhouse within the MATCH series for individual system concepts – not less than eight amplifier channels and even nine separate DSP channels make this extremely powerful Plug & Play amplifier to a sound virtuoso for the expansion of OEM sound systems.
The “heart” of the PP 86DSP is a 64 Bit DSP of the latest generation with enormous processing power and ultimate sound optimization opportunities. The package is complemented by Audiotec Fischers proprietary Class HD technology which combines maximum efficiency with minimum space requirements.
Besides a 6-channel highlevel input with ADEP circuit (Advanced Diagnostics Error Protection), the PP 86DSP is as well equipped with a MATCH Extension Card slot. This allows adding further interfaces like a Bluetooth® Audio Streaming module or a High Resolution Audio USB soundcard.
Thanks to the professional and user-friendly DSP PC-Tool V4 software with its bunch of new functions an individual sound setup becomes straightforward and intuitive. No doubt – a sound upgrade with this amplifier will be a lot of fun.

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 D ONE
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 bass reproduction – the active crossover with subsonic filter, the lowpass filter, phase control and bass boost are equally as self-evident as the intelligent highlevel input that incorporates Audiotec Fischer´s proprietary ADEP circuit. Not to mention the cable remote control for volume that is included in delivery.
Thanks to its 1-Ohm stability the D ONE is every else but choosy when selecting an appropriate subwoofer. If you still think that the power output isn’t sufficient, then simply combine two devices to one single powerhouse – the master/slave option makes it possible.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. Get your car “bass-tuned” and simply have fun!

Helix H 400X
The best of both worlds – extremely fast MOSFET driver circuits in Class A operation combined with enormously load-stable, power-potent “afterburners” in bipolar technology. This is the recipe for success for the particularly flat amplifiers, which, thanks to their sophisticated processor control, don’t get their feathers ruffled in any situation. Improved repeatedly over the years, these powerhouses with the characteristic and transparent enclosure covers have reached a sound level that is unrivalled, and not just in the value-for-money category.
