TANDBERG Videoconferencing System

Advanced use

Room Size

This setting allows optimization of the echo canceller to the acoustic size of the room. Hard walls, many windows etc. might require higher settings than expected. Carpets, curtains etc. might require lower settings. Adjust the setting (NOTE: on the far end) if one of the following symptoms occur:

There is still some echo of your own audio. Increase the setting.

The system adapts slowly to acoustic changes in the room. Decrease the setting. After a change, the system will need a few seconds to re-adjust.

Motion

If you experience echo caused by movements in the room, increase the value.
