You can mute an input strip. When you mute
            an input strip, it is not heard during playback, but its levels
            still appear on the pre-fader meters. You can also mute an input
            strip from the timeline.
         
         To mute a strip:
         
         
            - Enable the Mute button for the input
               strip that you want to mute.
               The strip is muted.
