Table 5-13 Configuring echo canceller related settings
Field Name Description
AGC Enables/disables Automatic Gain Control. The AGC reduces the
volume if the audio is strong and raises when it is weak.
Noise reduction Enables/disables reduction of ambient noise in a conference room
(e.g.: coughing, paper rustling, etc.).
Audio delay
automatic
estimation
An HDMI monitor might insert delay in the audio, causing an echo.
If you set this field to Yes, the XT Codec Unit improves its echo
canceller performance automatically. We recommend this setting
when you connect a new monitor to the XT Codec Unit.
If you set this field to No, you can generate the audio delay manually
and train the echo canceller to use the resulting audio for better
performance.
Audio delay Enables/disables the use of the audio delay value calculated when
activating audio delay automatic estimation.

Configuring Audio Outputs
The SCOPIA XT Series allows you to combine audio from various inputs and route it to
available audio outputs. The possible combination of inputs and outputs forms a matrix, which
is depicted in the SCOPIA XT Series system menus (Figure 5-31 on page 80).
The audio inputs to the system are:
•
Microphone pods
•
Analog audio input
•
Remote audio coming from other participants in the videoconference
Note
The audio from the analog inputs and microphones can be mixed and echo-cancelled.
These inputs can be mixed and routed to one or more of the following audio outputs:
•
Monitor speakers or other device connected to the HD1 port with an HDMI cable;
•
The analog output or the analog/optical port connected to a speaker or a device like a
recorder.
A typical audio configuration, depicted in Figure 5-31 on page 80, would be:
•
Route the remote audio to the speakers of one of the monitors (HD1), so you can hear the
other conference participants.
