Audio Output Line [1] Delay DelayMs
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.
Audio Output Line [1] Delay Mode
You may add extra delay to an audio line output with the Audio Output Line [n] Delay
DelayMs setting. The extra delay added is either a fixed number of milliseconds, or
a number of milliseconds relative to the detected delay on the HDMI output (typically
introduced by the connected TV).
Requires user role: ADMIN, INTEGRATOR
Default value: RelativeToHDMI
Value space: Fixed/RelativeToHDMI
Fixed: Any extra delay (DelayMs) added to the output, will be a fixed number of
millisecond.
RelativeToHDMI: Any extra delay (DelayMs) added to the output, will be relative to the
detected delay on the HDMI output. The actual delay is HDMI-delay + DelayMs. The
Audio Output Connectors Line [n] DelayMs status reports the actual delay.
Audio Ultrasound Mode
This setting applies to the Intelligent Proximity feature. Keep the setting at its default value.
Requires user role: ADMIN, INTEGRATOR
Default value: Dynamic
Value space: Dynamic/Static
Dynamic: The video system adjusts the ultrasound volume dynamically. The volume may
vary up to the maximum level as defined in the Audio Ultrasound Volume MaxVolume
setting.
Static: Use only if advised by Cisco.
Audio Ultrasound MaxVolume
This setting applies to the Intelligent Proximity feature. Set the maximum volume of the
ultrasound pairing message.
Requires user role: ADMIN, INTEGRATOR
Default value: 70
Value space: Integer (0..90)
Select a value in the specified range. If set to 0, the ultrasound is switched off.
