To adjust microphones for best far-end audio performance:
Check or clear the checkboxes for the desired adjustments:
n
Echo Cancellation
– Keeps microphones from feeding the speaker output back into the system. Under
most circumstances, echo cancellation is desirable.
n
Noise Cancellation
– Suppresses ambient noise such as the conference room's heating/air
conditioning.
n
Automatic Gain Control
– Adjusts gain to compensate for differences in the volume of people's
voices.
n
Mic Boost
– Provides a 3 dB boost.
EasyPEQ filtering offers additional options.
You may need to adjust the microphones to suit the room or the specific conference.
To correct this...
Do this
Reverberant room
From the Easy PEQ menu, select Reverberant Room.
Noisy environment
From the Easy PEQ menu, select Ambient Noise to reduce
gain in the frequencies above and below the normal speech
range.
Participants who have quiet voices or are
seated beyond the microphones' optimum
pick-up range
Select the Mic Boost processing option to increase
microphone gain overall.
From the Easy PEQ menu, select Speech Enhancement to
increase gain in the frequency range for speech.
Participants with widely differing vocal
volumes
Select the Automatic Gain Control processing option to
adjust microphone gain based on the relative volumes of
people's voices.
If two microphones are connected, they do not necessarily need to be set the same way – for example, one
microphone might be set to use Mic Boost while the other is not.
