Power Amplier 1000614100
Features
- Output for 1 amplified loudspeaker
- Output level control.
Description
The schematics for the board are in Chapter 23 from page 273 onwards.
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 subscriver 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.
