Key Features

  • The speech block can operate on line voltage, with no exter.
  • nal power supply, and is operational even during a commercial power failure. Incorporates auto. PAD, dial mute, DC voltage regulation, and other basic speech functions. The cross-point switch can be operated independently. Each output of the cross-point switch can correspond to multiple inputs, allowing three-or four-person communication. The REC/PLAY amplifiers incorporate ALC.
