Globally Muting video and audio signals

The Global Mute system is a unique feature that mutes all the video and audio signals to
enable easy integration of the audio system with public alarm systems used for alarms or
other public messages.

When global mute is triggered via the “REMOTE MUTE” terminal block port , all
HDMI/HDBT and analog outputs are globally muted and a warning note immediately appears
on the web pages heading:

Figure 21: Global Mute Warning

This warning note notifies the administrator that the system is muted due to a REMOTE
MUTE trigger. This trigger is indicated by the warning sign only and does not affect the
display of mute icons in the Routing Settings page. Mute icons ( or ) on the outputs, that
were set before the REMOTE MUTE was triggered, remain unchanged during the REMOTE
MUTE mode and after it ceases.

When the REMOTE MUTE mode is over, the system returns to normal operation and the
warning note disappears.
