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 G ONE
The new G amplifiers are more than just impressive power packs. They unite innovative technology, extensive functionality and best sound with a very attractive price to performance ratio.
If we do not talk about their more obvious features, such as fully active crossovers with highpass, lowpass, bandpass, bass boost and input mode switch for flexible input signal routing and smart high level input with ADEP circuits, we can still talk about how the G series also provides Start-Stop capability which is an exceptional feature in this price range. Wait, that’s not all… a remote control for adjusting the subwoofer level is included as part of the deal.
With such an extensive list of features in this piece of equipment, it is really not hard to realize a sound system in your car that has a great sound and lots of power for when you need it most.
Furthermore, the G amplifiers have the compact and straight HELIX design that has become synonymous with HELIX. In addition, for those who love a good light show, the logo has been illuminated for your viewing pleasure.
