Key Features

 

  • ● Eight automatic Mic/Line inputs, automatic gain adjustment by microprocessor control.
  • ● 15-unit daisy chain by accessory link cable to allow maximum 120 channels operation.
  • ● NOMA ”Number of Open Microphone Attenuated” helps control feedback.
  • ● 48V phantom power individually selectable for each channel, either line or microphone  output available.
  • ● LED shows working status and volume condition.
  • ● Any channel can be set to priority, when the “Chairman unit” is speaking, the other speaking units will be automatic attenuation.
  • ● An RS232 data port provides a connection point for a video camera tacking system.
  • ● The ASM-822automatic mixer is ideal for meetings, seminars, teleconferencing, house of worship services, broadcast and conference applications.
