Adjusting the audio output level (EM 300 G2 only)
AF Out
Via the “AF Out” menu, you can adjust the audio output level of the receivers.
The level can be adjusted in eight steps. Adapt the level of the audio output
(AF OUT) to the input of the connected unit. The following figures are a guide
to the best settings:
Line level input: 0 to +18 dB
Microphone level input: –24 to –6 dB
Adjusting the squelch threshold (EM 300 G2 only)
Squelch
The receiver is equipped with a squelch that can be adjusted via the
“Squelch” menu. The squelch eliminates annoying noise when the
transmitter is switched off. It also suppresses sudden noise when there is no
longer sufficient transmitter power received by the receiver.
Note:
Before adjusting the squelch threshold to a different setting, set the
volume on a connected amplifier to the minimum.
There are three possible squelch settings:
y Low = low
y Mid = middle
y High = high
Selecting the setting (Low) reduces the squelch threshold, selecting the
setting (High) increases the squelch threshold. Adjust the squelch threshold
– with the transmitter switched off – to the lowest possible setting that
suppresses hissing noise.
IMPORTANT! Notes:
If the squelch threshold is adjusted too high, the transmission range will
be reduced. Therefore, always adjust the squelch threshold to the lowest
possible setting.
When in the setting mode of the “Squelch” menu, pressing the ̄ button
(DOWN) for more than three seconds will switch the squelch off. “Off”
appears on the display. If no RF signal is being received, hissing noise will
occur. This setting is for test purposes only.
