Check out the Helix DSP Ultra Processor

The new HELIX DSP PRO MK2 ensures unrivaled sound characteristics with its extremely powerful 64 Bit Audio DSP and cutting-edge DA and AD converters and incredible native resolution of 32 Bit.

 The improved internal power supply as well as the increased maximum output voltage of 8 Volts contribute to the enhanced sound quality of this stunning processor. The HELIX DSP PRO MK2 provides a HELIX Extension Card slot (HEC slot) for additional input and output modules such as Bluetooth® Audio Streaming or the new USB-audio interface.

Main Features:

 

  • Extremely powerful “fixed point” Audio DSP with 64 Bit resolution and 1.2 billion MAC operations per second
  • AD and DA signal converters of the latest generation with a native resolution of 32 Bit
  • High Resolution audio bandwidth up to more than 40 kHz for unrivalled sound quality
  • HELIX Extension Card slot (HEC) for additional input / output modules like Bluetooth® Audio Streaming, High Resolution Audio Streaming via USB etc.
  • Smart highlevel input with ADEP circuit (Advanced Diagnostics Error Protection)
  • Start-Stop capability down to 6V supply voltage
  • Freely definable signal routing with separate matrices for line, SPDIF and HEC/AUX
  • “Ground lift” switch to avoid ground loops
  • Control input for connecting remote controls and accessories
  • Time alignment with up to 20 ms delay time per channel, additionally reverse time alignment for in-phase summation of the inputs

Special Features:

 

  • 96 kHz Sampling Rate – The HELIX DSP PRO MK2 allows to handle all signals with the doubled sampling rate of 96 kHz.
  • Signal Converters with a Native Resolution of 32 Bit – The HELIX DSP PRO MK2 uses high-class AD and DA converters of the latest generation with a native resolution of 32 Bit instead of the common 24 Bit.
  • Smart High-Level Input – The new ADEP circuit (Advanced Diagnostics Error Protection) avoids all possible problems without loading the speaker outputs of the OE radio during high volumes unnecessarily.
  • Start-Stop Capability – The switched power supply of the HELIX DSP PRO MK2 assures a constant internal supply voltage even if the battery’s voltage drops to 6 Volts during engine crank.
  • Power Save Mode – It allows to significantly reduce the power consumption of the amplifiers that are connected to the HELIX DSP PRO MK2 once there’s no input signal present for more than 60 seconds.
  • Automatic Digital Signal Detection – Switching from analog input to one of the digital inputs is done automatically as soon as a signal is detected on the Optical Input or Coax Input. This feature can be deactivated in the DSP PC-Tool software. Alternatively, you can use an optional remote control for manual switching between analog and digital inputs.
