7.5.3 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 ECS / 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.
Tip:
For information on adjusting panel microphone gain, see your ECS / EHX
documentation.
7.5.4 Speaker dim
When a panel microphone and a speaker are used together, feedback is possible.
To reduce this possibility, the panel software will mute (turn down) the speaker level by
some predetermined amount when both the microphone and speaker are enabled. The
speaker mute can be adjusted from 0 to 15 dB (its default setting is 6 dB).
Tip:
For information on adjusting speaker mute settings, see your ECS / EHX
documentation.
