Test StereoSurround

After you configure the system to use Polycom StereoSurround, test the system configuration and place a test call.


  1. Make sure the microphones are positioned correctly.
  2. In the system web interface, go to Admin Settings > Audio/Video/Content > Audio > Audio Input.
  3. Gently blow on the left and right leg of each Polycom microphone while watching the audio meters to identify the left and right inputs.
  4. 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.
  5. Optional: Exchange the right and left speakers if they are reversed.
  6. 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.
  7. Repeat the steps above for Admin Settings > Audio/Video/Content > Audio > Audio Output.
