About: Symetrix Voice Processor 2x DSP

The microphone is a crucial link to the audience. Proper management of that link is essential. The AirTools Voice Processor 2x is an outstanding programmable microphone processor that is flexible, powerful, and easy to use.

  • Two independently programmable channels of ultra-low latency digital mic processing in one rack space.
  • 2 mic/line inputs, word clock input, 2 mic/line outputs, 2 AES-3 outputs.
  • DSP specifically tailored for voice processing –  compression, EQ, de-essing, downward expansion, high and low pass filters, waveform symmetry.
  • Named presets for each on-air personality – up to 50.
  • Recall presets from the front panel or remotely.
