Audio Input Microphone [1..2] EchoControl NoiseReduction
The system has a built-in noise reduction which reduces constant background noise (for
example noise from air-conditioning systems, cooling fans etc.). In addition, a high pass filter
(Humfilter) reduces very low frequency noise. Requires the Echo Control Mode to be enabled
for the microphone.
Requires user role: ADMIN
Value space: <Off/On>
Off: Turn off the Noise Reduction.
On: The Noise Reduction should be enabled in the presence of low frequency noise.
Example:
Audio Input Microphone 1 EchoControl NoiseReduction: On
Audio Input Microphone [1..2] EchoControl Dereverberation
The system has built-in signal processing to reduce the effect of room reverberation. Requires

Requires user role: ADMIN
Value space: <Off/On>
Off: Turn off the dereverberation.
On: Turn on the dereverberation.
Example:

Audio Microphones Mute Enabled
Determine whether audio-mute is allowed or not. The default value is True.
Requires user role: ADMIN
Value space: <True/InCallOnly>
True: Muting of audio is always available.
InCallOnly: Muting of audio is only available when the device is in a call. When Idle it is not
possible to mute the microphone. This is useful when an external telephone service/audio
system is connected via the codec and is to be available when the codec is not in a call.
When set to InCallOnly this will prevent the audio-system from being muted by mistake.
Example:
Audio Microphones Mute Enabled: True
Audio SoundsAndAlerts KeyTones Mode
The system can be configured to make a keyboard click sound effect (key tone) when pressing
a key on the remote control, or when typing text or numbers on the Touch controller.
Requires user role: USER
Value space: <Off/On>
Off: No key tones will be played when you type.

Example:
