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.

PCS-A1 (not supplied) or PCS-A300 microphone (not supplied)

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.
