Advanced Transmitter Features
To correct, set MIC.OFFSET to 0 dB and if
necessary, attenuate the signal source.
If the source cannot be attenuated while using a
bodypack transmitter, select INPUT PAD from the
main menu to attenuate the input signal by 12 dB.
Use this to turn on a transmitter without interfering
with the RF spectrum.
Press and hold the exit button during power-on
until RF MUTED is displayed. To un-mute, restart
the transmitter.
The following warning displays on the receiver
LCD panel when the transmitter input is clipped:
MIC.OFFSET compensates for signal level
differences between transmitters that share the
same receiver channel.
Set the offset gain on a low signal level
transmitter to match a louder transmitter: UTILITY
> MIC.OFFSET
Note: For normal gain adjustments, use the
receiver gain buttons.
