Using Multiple Microphones
The microphone built in the PCS-C1/C1P Camera Unit is assumed to be used
to conduct a conference among about three participants. You can connect the
optional PCS-A1 or PCS-A300 microphone to the System, allowing more
persons to participate in the conference.
To connect the optional microphones
Connect the optional microphones to the MIC 1 and MIC 2 connectors on the
Communication Terminal. Power is supplied to the microphones from the
Terminal.
To use the connected microphone
Set “Mic Select” to “External” in the Audio Setup menu. (See page 43.)
In this case the built-in microphone is disabled.
Notes on installation of the microphones
• Install microphone about 50 cm away from the participants.
• Install the speakers behind the microphones.
• Place the microphone in a quiet, echo-free location.
• Install microphones away from equipment that may cause noise.
• Avoid covering a microphone with paper, etc., or moving it. If you do either,
extreme noise and echo may be heard temporarily by the remote party. In this
case, wait until the echo disappears.
