Helix DSP.3S
Helix DSP.3S is a new improved version of the popular Helix DSP.3 model. The Helix DSP.3S is guaranteed to be one of the best DSP processors on the market for its price/performance ratio.

ACO
The ACO platform (ACO = Advanced 32 Bit CoProcessor) makes the device incredibly fast and efficient.

ISA & InputEQ
The Helix DSP.3S model features ISA (Input Signal Analyzer) and InputEQ (Input Signal Measurement and Equalization). The ISA measures the frequency response of the input signal and the InputEQ is a 5-channel per-channel parameter corrector to correct for possible distortions in the frequency response of the input signal. This provides a proper starting point for the best possible audio performance.

Signal Input
The signal can be input as speaker level, line level, optical or via the optional Helix HEC module via Bluetooth or HD level via USB cable.

Powerful Processor
Processor speed is a very important feature when adjusting an audio system. The slower the processor, the more the dynamics are flattened when adjusting eqvals or divider slopes. This processor features a state-of-the-art 64-bit 295Mhz processor with 1.2 billion calculations per second

Autostart
The High Level Input has the most advanced Autostart function on the market with a switch-off delay of 10-300 seconds. The device will only switch on when it detects the correct speaker signal, and will not react to start-up bursts or other disturbances. Like Audiotec Fischer's other plug&play devices, it is ideal for CAN bus radios, where the radio can be on for up to 40 minutes after locking the doors.

8 channels
This device allows you to do all the sections of a 4-way system and the delay of each element. Or active 2-way front, subbar and rear speakers. Or any combination you like. There are 8 channels available, with customizable characteristics for each channel.

Helix HEC Modules
This model is also available with an in-dash Helix HEC Bluetooth, Helix HEC HD-Audio USB, Helix HEC AUX IN or Helix HEC OPTICAL IN module.
