Positioning Microphones to Send Stereo
© Polycom, Inc.
Connect cable with ferrite
bead on system end of
cable.
The VSX room systems allow you to send stereo using one or two microphone
pods.
Polycom recommends using two microphone pods with VSX 7000 and VSX 8000 systems
in large rooms.
The microphone pod contains a microphone array. If you connect a single
microphone pod to the system with StereoSurround enabled, one microphone
element picks up audio from the left side of the room, one picks up the right side
of the room, and the third is disabled, as shown in the following diagram.

Chapter 2 - Setting Up Your System Hardware
Use conference link cable with maximum
length of 50 ft (15 m).
Place closest microphone
pod at least 3 ft (0.9 m) from
the system and subwoofer.
Use conference link cable
without a ferrite and with
maximum length of 30 ft (9 m)
for an additional microphone
pod. Do not exceed the
length of the cable from the
system.
Place microphone pods at
least 6 ft (1.8 m) apart.
