Test Polycom StereoSurround
After you configure the system to use Polycom StereoSurround, you can place a test call to see if it
works.
Make sure the microphones are positioned correctly.
The Studio X30 system doesn’t support stereo audio.
Procedure
1.
In the system web interface, go to
Audio/Video
>
Audio
>
Audio Input
.
2.
Gently blow on the left and right leg of each microphone while watching the audio meters to
identify the left and right inputs.
3.
Test the speakers to check volume and verify that audio cables are connected.
If the system is in a call, the far site hears the tone.
4.
Optional: Exchange the right and left speakers if they are reversed.
5.
Adjust the volume control on your external audio amplifier so that the test tone sounds as loud as
a person speaking in the room. If you use a Sound Pressure Level (SPL) meter, it should measure
approximately 80 to 90 dBA in the middle of the room.
6.
Repeat these steps for
