values represented in dB.
Range: -24 to 0 dB
Example:
xConfiguration Audio Input HDMI 3 Level: 0
xConfiguration Audio Input HDMI [3, 4] Mode:

Left: The Audio Line input signal is the left channel of a stereo signal.
Right: The Audio Line input signal is the right channel of a stereo signal.
Mono: The Audio Line input signal is a mono signal.
Example:
xConfiguration Audio Input 1 Channel: Left
xConfiguration Audio Input Line [1..4] Level:
<0..24>
Defines the input level of each Line input in steps of 1dB from 0dB to 24 dB. Addresses the specific Audio
Line input.

xConfiguration Audio Input Line [1..4] LoopSuppression:
<On/Off>
Loop suppression detects whether a delayed signal loop is present from an audio Line output to an audio
Line input on the codec. If a loop is detected this unwanted feedback is suppressed.
On: Set to On to activate Loop Suppression.
Off: Set to Off to deactivate Loop Suppression.
NOTE! Only loops between line output 3 and line input 3, and between line output 4 and line input 4 are
suppressible.
Example:
xConfiguration Audio Input Line 3 LoopSuppression: On
xConfiguration Audio Input Line [1..4] Mode:
<On/Off>
Determines whether or not an Audio Line input is enabled. Addresses the specific Audio Line input.
On: Set to On to enable the Audio Line input.
Off: Set to Off to disable the Audio Line input.
Example:
xConfiguration Audio Input Line 1 Mode: On
xConfiguration Audio Input Microphone [1..8] EchoControl Mode:
<On/Off>
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. Addresses the specific microphone.
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
xConfiguration Audio Input Microphone [1..8] EchoControl NoiseReduction:
<On/Off>
The system has a built-in noise reduction which reduces constant background noise (e.g. 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 specified microphone. Addresses the specific
microphone.
On: The Noise Reduction should be set to On in the presence of low frequency noise.
Off: Turns Noise Reduction Off for the specified microphone input.
Example:
xConfiguration Audio Input Microphone 1 EchoControl NoiseReduction: On
xConfiguration Audio Input Microphone [1..8] Level:
<0..24>
Defines the input level of each microphone in steps of 1dB from 0dB to 24 dB. Addresses the specific
microphone connector.
See the Audio Level tables in the Codec C90 System Integrators Guide for a complete overview of the menu
values represented in dB.
Range: 0 to 24 dB
Example:
xConfiguration Audio Input Microphone 1 Level: 15
