Setting Microphones
Your system recognizes that a PowerMic is conÞgured with your
system and automatically disables all other tabletop microphones,
except for lapel microphones which remain active. Generally, this is
the preferred mode of operation. However, you can use the

Microphones
menu to include tabletop microphones in the
videoconference.
You can also use the
Set Microphones
menu to specify what types of
microphones (other than a PowerMic) you have plugged into each
of the two
MIC
(
A
and
B
) connections on the Audio board.
To set the microphone(s):
