Setting Description
Autorotation Specifies whether the system uses autorotation for Poly 
microphones. If you enable this feature, the system 
automatically assigns left and right channels for the 
microphone based on the sound it senses from the left 
and right speakers.
Configuring the Microphone Adapter
The video system automatically configures Poly Microphone IP Adapter when you pair it.
The Studio X70, Studio X52, Studio X50, and Studio X30 systems don’t support the microphone 
adapter.
Note the following when using the microphone adapter:
● You can’t use Poly IP table and ceiling microphones.
● Polycom StereoSurround isn’t available.
● The audio input level (mono channel meter) displays in the local interface and system web 
interface.
● Polycom Acoustic Fence technology isn't supported.
● The RealPresence Group Series microphone array configuration uses stereo audio by default, but 
the microphone adapter supports only mono mode.
Polycom Acoustic Fence
Polycom Acoustic Fence technology creates a virtual 
audio fence
 that blocks sounds from outside the 
fence. It suppresses background noise during calls to enhance audio quality for call participants.
Polycom Acoustic Fence works in mono mode only and disables Polycom StereoSurround when 
enabled.
Polycom Acoustic Fence technology provides the following:
● Mutes sounds outside the fence when no one is speaking inside it
● Lowers sounds outside the fence by 12 dB when someone is speaking inside it
● Mutes speakers when someone leaves the fenced area
● Enables you to adjust the width of the audio fence 
beam
 to define the area where sounds are 
picked up
For Studio X70, Studio X52, Studio X50, and Studio X30 Systems:
Once you enable Polycom Acoustic Fence on your Studio X70, Studio X52, Studio X50, and Studio 
X30 system, you can also adjust the width of the audio fence beam so that the system’s built-in 
microphones pick up sound in the area you want.
For G7500 Systems:
Once you enable Polycom Acoustic Fence, you must set up additional hardware to use this feature 
with your G7500 system. You need a primary microphone and at least one more microphone to 
create the fence.
