5.3.3 Microphone

Set the microphone and line audio input volume parameters in this intercom

configuration section. The microphone volume settings are closely associated with the

speaker sensitivity parameters and intercom installation site conditions, which affect

the general audio reproduction and recording quality. If you notice a deteriorated audio

quality, please read the

parameters on your installation site properly.

List of Parameters

Microphone sensitivity – set the microphone sensitivity.

Microphone AGC enabled – set the automatic gain control (AGC) mode for

the microphone.

AEC artefacts reduction – enable cancelling of interfering noise (i.e. artefacts

caused by cancellation of the local acoustic feedback on the intercom installation

site); refer to the Specification of Audio Parameter Function parameter.
