• Input channels have the following parameters: Gain, Noise gate, Delay, Polarity and Parametric EQ.
  Output channels have the following parameters: Gain, Delay, Polarity, Crossover, Compressor/Limiter, Matrix and Parametric EQ.
• Includes an internal signal generator (pink noise, white noise, etc).
• Includes master password option (blocking unwanted or unauthorized use of the unit).
• Matrix and mute in channels can be controlled by connecting a mixer and the device by USB or RS485.
