Procedure
1. Access the XT Series's echo cancellation settings. From the XT Series web interface,
select Administrator settings > I/O connections > Audio-Inputs > Echo Canceller.
From the endpoint's main menu, select Configure > Advanced > I/O connections >
Audio-Inputs > Echo Canceller.
2. Set the fields as required.
Table 43: Configuring echo cancellation settings
Field Name Description
AGC Enables/disables AGC. Automatic Gain Control (AGC) smooths audio
signals through normalization, by lowering sounds which are too strong
and strengthening sounds which are too weak.
Typically, you enable AGC for optimal audio. However, you may want to
disable it if your microphone is strengthening the sound of background
noise, mistaking it for your voice.
Noise reduction Enables/disables reduction of background noise in a conference room
(like coughing, paper rustling, or the hum of an air conditioning system).
Typically, you enable Noise reduction for optimal audio. However, you
may want to disable it some voices are filtered out as background noise,
which causes breaks in the audio.
Audio delay
automatic
estimation
An HDMI monitor might cause a delay in the audio, causing an echo.
Set this field to Yes to improve its echo cancellation performance
automatically. We recommend this setting when you connect a new
monitor to the XT Series.
If you set this field to No, you can generate the audio delay manually and
train the echo cancellation to use the resulting audio for better
performance. For details, see Cancelling the Echo on HDMI Monitors on
page 265.
Audio delay Select Yes to use the estimated audio delay.
Typically, you enable Audio delay for optimal audio. However, you may
want to disable it if your room has a strong echo that creates a
reverberating effect, which may produce false results when estimating the
audio delay.
3. From the web interface only, select Save.
