C20 AEC

[suporte]

Hello, I`d like to know if the C20 Videoconferencing System has the option to enable Echo Cancellation on the line input.

Thank you.

Software version might be helpful.

Have you looked at the xconfig commands:

xConfiguration Audio EcReferenceDelay Mode
Set the acoustic echo cancellation reference delay mode.
Requires user role: ADMIN
Value space: <Off/Fixed>
Off: No extra latency will be added to reference signal used by the acoustic echo canceller.
Fixed: The extra latency given by Audio EcReferenceDelay Delay will be used to compensate for
latency in the acoustic path, typically introduced by TV monitors.
Example: xConfiguration Audio EcReferenceDelay Mode: Off
xConfiguration Audio EcReferenceDelay Delay
Adjust the time slot (in milliseconds) of the acoustic echo cancellation. Only applicable when Audio
EcReferenceDelay Mode is set to Fixed.
Requires user role: ADMIN
Value space: <0..250>
Range: Value from 0 to 250 milliseconds.
Example: xConfiguration Audio EcReferenceDelay Delay: 120

Echo cancellation only applies to microphone inputs, does not apply to line inputs.
