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.

Helix V EIGHT DSP
$7,000.00The HELIX V EIGHT DSP 8-channel amplifier with integrated 10-channel signal processor opens up new horizons for car audio enthusiasts.
Its unique “Pure Class GD” concept and cutting-edge “fixed point” Audio DSP with 64 Bit resolution ensures extraordinary sound quality and loads of power.
Furthermore, a huge feature set provides the ideal set of pre-requisites for more complex system concepts – especially if fully active configurations are going to be built on a single and compact amplifier.
Eight speaker outputs with up to 120 Watts RMS @ 2 Ohms, two processed RCA outputs for the connection of additional amplifiers, six RCA and six highlevel inputs with up to 20 V RMS input sensitivity and an optical SPDIF input make this amplifier absolutely unique in its class. The HELIX Extension Card slot (HEC) allows adding even more interfaces, like the Bluetooth® Audio Streaming module or a High Resolution Audio USB soundcard.
Thanks to Audiotec Fischer’s DSP PC-Tool, the integrated DSP can be easily configured to ones individual requirements. Despite the gigantic feature content, the V EIGHT DSP presents itself in the classic HELIX design language, a clean design with very compact dimensions allows for a quick and easy integration.

Match UP 7DSP
The UP 7DSP is the most powerful MATCH DSP amplifier and comprises our new ADEP.3 circuitry. It offers seven amplifier channels in total as well as an additional preamp output, which allows – in combination with its integrated 8-channel DSP – to perfectly drive individual and complex speaker configurations. Two of the output channels deliver 160 Watts RMS into 2 Ohms – plenty enough for fuelling even large subwoofers.
But brute force is nothing without “smart control” – that’s why the UP 7DSP incorporates a stunning powerful 64 Bit DSP of the latest generation, which enables to realize all-new revolutionary and proprietary sound features like the “Augmented Bass Processing”, the “StageXpander” or the “RealCenter” function. Take us by our word – you will experience a truly breathtaking sound performance.
But that’s not enough – simply enjoy music from your smartphone in unprecedented quality. The UP 7DSP comes up with a MATCH Extension Card slot (MEC) for additional input and output interfaces like e.g. our Bluetooth® Audio Streaming module or a High Resolution Audio USB sound card.
Thanks to our professional and user-friendly DSP PC-Tool software V4 the configuration and set-up of the UP 7DSP is pretty straightforward and intuitive.

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.
