HELIX

Processore HELIX DSP 8 canali

  • Extremely powerful “fixed point” Audio DSP with 64 Bit resolution and 1.2 billion MAC operationsper second
  • HELIX Extension Card slot (HEC) for additional input / output modules like Bluetooth® Audio Streaming
  • 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
  • Time alignment with up to 20 ms delay time per channel, additionally reverse time alignment for in-phase summation of the inputs
  • Optimized signal path and power supply for further improved sound quality
  • “Ground lift” switch to avoid ground loops
  • Control input for connecting remote controls and accessories
  • Inputs: 6 x RCA/Cinch, 6 x Highlevel and 1 x optical SPDIF
  • Outputs: 8 x RCA/Cinch with max. 6 Volts output voltage
  • Easy configuration thanks to the professional and user-friendly DSP PC-Tool Version 4 software
