API Reference Guide
xConfiguration Audio Input Line [1..2] Channel
Define whether the Audio Line input is a mono signal or part of a multichannel signal.
Requires user role:
ADMIN
Value space:
<Right/Left/Mono>
Right:
The Audio Line input signal is the right channel of a stereo signal.
Left:
The Audio Line input signal is the left 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..2] Level
Define the audio level of the Line input connector, in steps of 1 dB.
See the Audio Level tables in the Physical Interfaces Guide for the codec for a complete overview of
the menu values represented in dB.
Requires user role:
ADMIN
Value space:
<0..24>
Range:
Select a value from 0 to 24 dB.
Example:
xConfiguration Audio Input Line 1 Level: 10
xConfiguration Audio Input Line [1..2] LoopSuppression
Codec C40 and C60 currently does not support loop suppression, hence it is always Off.
Requires user role:
ADMIN
Value space:
<Off>
Off:
Deactivate Loop Suppression.
Example:
xConfiguration Audio Input Line 1 LoopSuppression: Off
xConfiguration Audio Input Line [1..2] Mode
Set the audio input line mode.
Requires user role:
ADMIN
Value space:
<Off/On>
Off:
Disable the Audio Line input.
On:
Enable the Audio Line input.
Example:
xConfiguration Audio Input Line 1 Mode: On
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.
Requires user role:
ADMIN
Value space:
<Off/On>
Off:
Echo Control should be switched Off if external echo cancellation or playback equipment is
used.
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.
Example:
xConfiguration Audio Input Microphone 1 EchoControl Mode: On
xConfiguration Audio Input Microphone [1..2]/[1..4] EchoControl NoiseReduction
NOTE: Codec C40 has two microphone connectors. Codec C60 has four microphone connectors.
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:
xConfiguration Audio Input Microphone 1 EchoControl NoiseReduction: On
xConfiguration Audio Input Microphone [1..2]/[1..4] EchoControl Dereverberation
NOTE: Codec C40 has two microphone connectors. Codec C60 has four microphone connectors.
The system has built-in signal processing to reduce the effect of room reverberation. Requires the
Echo Control Mode to be enabled for the microphone.
Requires user role:
ADMIN
Value space:
<Off/On>
Off:
Turn off the dereverberation.
On:
Turn on the dereverberation.
Example:
xConfiguration Audio Input Microphone 1 EchoControl Dereverberation: On
