Page Line Audio 600-ohm Monitor Output
The Model LE200 mixes the local and remote page line audio and broadcasts it out a 600-ohm monitor
output. For the output voltage to be at the expected level, the device attached to the monitor output
should have an input impedance of 600 ohms. DIP switch SW3 selects the monitor output’s gain.
