Cisco DX70 and DX80 Administrator Guide
Audio Input MicrophoneMode
This setting applies only to DX80.
The DX80 has microphones in both legs. If you set the microphone mode to Focused, the
microphones can be combined to focus sound sensitivity. As a result, the noise in the room
is suppressed, and you can be heard better when sitting right in front of the video system.
The voice of people not sitting right in front of the system will be suppressed.
If you set the microphone mode to Wide, the system behaves like any other system. The
voice of people sitting beside you will be heard, and also more noise from the room.
We recommend that you use Focused mode when you are the only speaker. Use Wide
mode when several speakers are in front of the system.
