Connecting Speakers

You must connect at least one speaker to play audio from the far site. You can use the speakers built into the main monitor, or you can connect an external speaker system such as the Polycom StereoSurround™ kit to provide more volume and richer sound in large rooms. Refer to your system’s setup sheet for connection details.

Placing Speakers to Play Stereo from Far Sites

The Polycom StereoSurround kit is designed for use with Polycom HDX systems. It includes two speakers and a subwoofer.

When you set up the system for StereoSurround, the left microphone and speaker should be on the left from the local room perspective. Place the speaker connected to the audio system’s right channel on the right side of the system, and the other speaker on the left side. The system reverses the left and right channels for the far site, as shown in the following illustration. This ensures that the sound comes from the appropriate side of the room.
