Page Line Audio Monitoring Output
The Model LE300-IP Line Extender provides a balanced 600-ohm audio output for monitoring audio on
both the local and remote page lines. The LE300-IP mixes the local and remote page line audio and routes
it to the 600-ohm audio output terminals. This audio can be sent to any external audio device (recorder,
radio transmitter, amplifier, etc.) with an input impedance equal to or greater than 600 ohms. The audio
output gain is adjustable using DIP switch SW3 positions 5–8 on the Main PCBA. Refer to Figure 6 for
the location of Switch SW3 on the Main PCBA and the tables below for setting options.
