External Monitor Input
STEP 10- OFF AIR MONITORING
The Monitor Selector Switch (EXT) is usually used to monitor the actual radio station on air signal from a radio tuner.
NOTE: it is important to monitor the actual signal from the radio station and not just the output of the console. This is so as to monitor the entire radio chain
from the console to the transmitter.
INSTALLATION
Connect the output of a radio tuner or professional on air monitor to the EXT IN connector on the back of the console.
IMPORTANT: if using a consumer tuner, use a line level output and not the speaker output.
CALIBRATION
The EXTERNAL IN is calibrated to -10dBu input level.
TEST
Set up the tuner or monitor to your station’s frequency and switch the console control room monitor to the EXT position. You should hear the audio output of the
tuner. Audio quality should be high and there should be no objectionable audio hum.
