Power Amplier 1000614100

Features

  • Output for 1 amplified loudspeaker
  • Output level control

Description

The board contains a power amplifier, a potentiometer for adjusting the output volume and an input for switching the amplifier on/off.

The symetrical input is matched to the output level on the subscriber board in the AlphaCom exchange.

The amplifier may be constantly on, or switched on and off by the M-key on the calling station. It is recommended that power to the amplifier board is supplied from a separate class II transformer. <br\> In the AlphaCom exchange, brackets must be mounted on the board, in order to fasten to the mounting rail.

To balance out hum and noise.
