Connecting Polycom Microphones

To pick up audio from your site, you must connect a microphone to the system. Refer to your system’s setup sheet for connection details.

Polycom microphones each contain three microphone elements for 360° coverage. The microphone picks up sound from the sides. You can connect multiple Polycom microphones to a Polycom HDX system.

For best audio:

•Place the microphone on a hard, flat surface (table, wall, or ceiling) away from obstructions, so the sound will be directed into the microphone elements properly.

•Place the microphone near the people closest to the monitor.
