The following table shows the acceptable input levels and video associations

for the audio inputs on the Polycom HDX system.

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.
