Panel microphone gain
The preamplifier gain of the panel microphone can be adjusted over a range of +20 to +70 dB; the panel microphone gain’s default setting is 50 dB. However, if two panels are talking to each other at the same time with the panel microphone gain set to maximum, feedback may occur even if the speaker dim is set to maximum in EHX.
In this case, it will be necessary to turn the panel microphone gain down. Similarly, in some noisy environments it may be necessary to turn the panel microphone gain down and have the operator talk more closely into the microphone.
For information on adjusting panel microphone gain, see your EHX documentation.
