Helix V eight DSP 8-channel amplifier

The 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.
