Digital 8-channel signal processor with 48 kHz / 24 Bit signal path

The first stand-alone DSP that deserves to be called a HELIX. The new HELIX DSP is more than convincing proof that noisy, distorting sound processors are finally a thing of the past. Excellent technical specs are combined with a feature package that could hardly be more impressive in actual practice. Intuitive operation thanks to a clearly structured graphical PC interface enables any ambitious sound freak to optimize the sound virtually any which way.

  • Powerful fixed point Audio DSP with 56 Bit resolution
  • Freely configurable inputs and outputs with flexible signal summing options
  • Paragraphic 30-band EQ per channel with ultra-precise 0.25 dB steps
  • Time-alignment adjustment in narrow 7 mm steps and phase control in 11.25 steps
  • Various high- and lowpass filter characteristics with 6 - 30 dB slope available
  • Different signal routing matrices for each signal input section including configurable signal detections
  • Ground lift switch to avoid ground loops
  • Control input for connecting remote controls and accessories
  • Easy configuration thanks to the professional and user-friendly DSP PC-Tool Version 3 software

Power Save Mode
The Power Save Mode is incorporated in the basic setup. It allows to significantly reduce the power consumption of the amplifiers that are connected to the HELIX DSP once there's no input signal present for more than 60 seconds. Please note that in many up-to-date cars with CAN” or any other internal bus structures it may happen that the radio remains invisibly turned on for up to 45 min. even after leaving the car! Once the Power Save Mode is active the Remote Output and therefore the connected amplifiers will be turned off. The HELIX DSP will reactivate the Remote Output” within a second if a music signal is applied. It is possible to either modify the turn-off time of 60 sec. or completely deactivate the Power Save made via the DSP PC-Tool software.

Start-/Stop capability
The switched power supply of the HELIX DSP assures a constant internal supply voltage even if the battery's voltage drops to 6 Volts during engine crank.

Automatic Digital Signal Detection
Switching from analogue input to digital input is done automatically as soon as a signal is detected on the optical input. This feature can be deactivated in the DSP PC-Tool software. Alternatively, you can use the optional cable remote control URC 2A for manual switching between analogue and digital inputs.
