To pick up audio from your site, you must connect a microphone to the
Polycom QDX 6000 system. The microphone picks up sound from the sides.
You can connect multiple Polycom microphones to a Polycom QDX 6000
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.
In large conference rooms, you may need more than one microphone.
Each Polycom microphone covers a 3-6 foot radius, depending on the
noise level and acoustics in the room.
