Introduction

Audio Input Microphone [n] EchoControl NoiseReduction

n: 1..8
The video conferencing device has built-in noise reduction, which reduces stationary
background noise, for example noise from air-conditioning systems, cooling fans etc. In
addition, a high pass filter (Humfilter) reduces very low frequency noise. Noise reduction
requires that Audio Input Microphone [n] EchoControl Mode is enabled.
Requires user role: ADMIN, INTEGRATOR
Default value: On
Value space: Off/On
Off: Turn off the noise reduction.
On: Turn on the noise reduction. Recommended in the presence of low frequency noise.

Audio Input Microphone [n] Level

n: 1..8
Set the gain on the Microphone input connector. The gain should be adjusted to suit the
output level of the connected audio source. The gain can be tuned in steps of 1 dB.
If the gain is set too high, the audio signal will be clipped. If the gain is set too low, the audio
signal-to-noise ratio will be degraded; however, this is usually preferable to clipping.
Note that unprocessed speech signals typically contain significant level variations, making it
very important to allow for sufficient signal headroom.
The maximum input level with 0 dB gain, is 24 dBu.
Example: If your microphone has a maximum output level of -44 dBu, then you should set
the gain to 24 dBu - (-44 dBu) = 68 dB.
Requires user role: ADMIN, INTEGRATOR
Default value: 58
Value space: Integer (0..70)
Range: Select the gain in decibel (dB).

Audio Input Microphone [n] Mode

n: 1..8
Disable or enable audio on the microphone connector.
Requires user role: ADMIN, INTEGRATOR
Default value: On
Value space: Off/On
Off: Disable the audio input microphone connector.
On: Enable the audio input microphone connector.
