Audio Input Microphone [N] Level; Audio Input Microphone [N] Mode; Audio Microphones Mute Enabled; Audio Output Line [N] Delay Delayms - Cisco TelePresence SX10 Quick Set Administrator's Manual

Cisco TelePresence SX10 Quick Set

Introduction

Audio Input Microphone [n] Level

n: 2..2
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 -18 dBu.
Example: If your microphone has a maximum output level of -40 dBu, then you should set
the gain to -18 dBu - (-40 dBu) = 22 dB.
Requires user role: ADMIN, INTEGRATOR
Default value: 17
Value space: Integer (0..24)
Range: Select the gain in decibel (dB).

Audio Input Microphone [n] Mode

n: 1..2
Disable or enable audio on the microphone connector. Note that Microphone [1] is the video
system's internal microphone.
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.

Audio Microphones Mute Enabled

Define the microphone mute behavior on the video system.
Requires user role: ADMIN, INTEGRATOR
Default value: True
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.

Audio Output Line [n] Delay DelayMs

n: 1..1
To obtain lip-synchronization, you can configure each audio line output with an extra delay
that compensates for delay in other connected devices, for example TVs and external
loudspeakers. The delay that you set here is either fixed or relative to the delay on the HDMI
output, as defined in the Audio Output Line [n] Delay Mode setting.
Requires user role: ADMIN, INTEGRATOR
Default value: 0
Value space: Integer (0..290)
The delay in milliseconds.
