Placing Polycom Microphones to Send Stereo from Your Site
If you use a single microphone to send stereo, 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 not used. When a single Polycom microphone is connected to
a Polycom HDX system with stereo enabled, you can use the Stereo
Autorotation feature. This feature senses sound energy from the left and right
speakers and automatically assigns left and right channels for the microphone.
