Set Mic Gain
Set the mic gain properly to assure the best audio quality. To set the mic gain for the beltstation Headset:
Press Menu to enter Menu Mode. From the Main Menu select “Set Controls”, then “Mic Gain”.
While at the “Mic Gain” screen talk into the headset microphone at a louder than normal level and adjust
the Volume control until the Peak LEDs just start to light at the loudest parts of the audio. Press Enter to
accept the changes.
Mic Gain can be set in the beltstation without activating the Talk button. This allows private mic gain
adjustment during live events.
When the mic gain is set too high it is possible to induce feedback or echo. When set too low, words can
be clipped by the low level noise gate or sounds too quiet to other listeners. Headsets by different
manufacturer’s or different models of headsets will require widely varying Mic Gain settings. When setting
microphone gain it is best to err toward a setting that is too low, rather than too high. This will help reduce
unwanted echo in the system when that microphone is enabled.
