xConfiguration Audio Input Microphone [1..2]/[1..4] EchoControl Mode
NOTE! Codec C40 has two microphone connectors. Codec C60 has four microphone connectors.
The echo canceller continuously adjusts itself to the audio characteristics of the room and compensate for
any changes it detects in the audio environment. If the changes in the audio conditions are very significant
the echo canceller may take a second or two to re-adjust.
Value space: <On/Off>
On: Echo Control is normally set to On to prevent the far end from hearing their own audio. Once
selected, echo cancellation is active at all times.
Off: Echo Control should be switched Off if external echo cancellation or playback equipment is used.
Example: xConfiguration Audio Input Microphone 1 EchoControl Mode: On

air-conditioning systems, cooling fans etc.). In addition, a high pass filter (Humfilter) reduces very low
frequency noise. NOTE! Requires the Echo Control Mode to be enabled for the microphone.
Value space: <On/Off>
