  • Up to 300 conference microphones (ATUC-50DU + ATUC-M) can be connected by cascade-connection
  • 4 configurable balanced matrix output plus 1 unbalanced output that outputs the same audio as Output 1
  • 2 Mic/Line inputs, 2 monaural AUX inputs, and 2 return inputs
  • 2 return channels are available for both bilingual simultaneous interpretation and the language of the floor holder
  • Conference mode: Free Talk, Request Talk, and Full Remote
  • Priority mode: First-press priority and later-press (FIFO, LIFO) priority
  • Talk mode: Manual mode, Voice activation mode
  • Web Remote enables you to easily change settings and control attendees' right to talk during conference
  • Up to 4 channels (WAV: up to 4 channels, MP3: up to 2 channels) can be recorded on a USB device (mass storage device)
