Administrator's Guide for Polycom CX7000 Systems
Positioning Your Microphone
Powering the System On and Off
4
The Polycom CX7000 system uses a built-in echo canceller which
automatically adjusts the audio to prevent the sound of far-end voices from
being sent back to the far end. The system is designed to provide excellent
audio in small to medium conference rooms. A number of factors can affect
audio quality including the volume of the system, the sensitivity of the
microphone, the acoustic qualities of the room, and the acoustic qualities of
any audio devices that combine microphone and speakers.
For best audio results, follow these guidelines:
•
Place the microphone and speakers as far apart as possible, especially if
you are using external speakers and the Polycom microphone array.
•
For best microphone performance, place the microphone no more than 1
meter from the person who is speaking. Speaking too far from the
microphone can keep the far end from hearing you.
•
For most effective echo cancellation, keep the volume on your system's
speakers at a moderate level. Excessive volume can cause audio problems
such as clipping or echo.
•
Place the microphone on the meeting table so that each meeting
participant is closer to the microphone than the loud speakers.
•
To avoid undesirable sound transfer, avoid placing the microphone and
the loud speakers on the same table.
Connect power and power on the Polycom CX7000 system after you have
connected all of the equipment that you will use with it. Make sure that the
system is powered off before you connect devices to it.
