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.
