These units are suited for use in bars, retail stores, and banquet rooms, and are equipped with the MOH output that permits 2-channel broadcast when used in conjunction with the optional booster amplifier BA-235 (35 W) or BA-260 (60 W).

  • Each input freely assignable to the MOH output.
  • Automatic or manual mute function.
  • Easy setting of each function with the rear-mounted DIP switches. (Each input to MOH output assignment settings, Mute settings, LINE 1/TEL level settings, and Phantom power ON/OFF setting)
