Chapter 13: Muting
You can interrupt (mute) the output signal of a channel. This is generally used for
backstage mics, guitar switch over etc. Channel mutes can be activated by any of the
following, which (except the VCAs) mute the channel outputs and update the channel
mute status indicator:
•Local MUTE button press.
• Auto-mutes (mute groups/control groups) — see “Auto-mute (mute) groups” on
page 180.
• VCAs — see “VCA and POP groups” on page 177.
• Scene recall (automation) — see Chapter 20 "Scenes And Shows (Automation)" on
page 197.
• SIP — see “Solo in place (SIP)” on page 139.
To see which outputs are affected by channel muting, refer to Appendix B “Functional
Block Diagrams”.
Control methods, interactions and corresponding states of channel mute. In the
diagram, all of the transitions between states, with the exception of State 1 to State 0
“If not SIP muted”, are events. The “If not SIP muted” transition is not an event, it
happens as soon as the indicated test condition (“If not SIP muted”) is true. Also,
“Mute on” and “Mute off” refer to mute activations and deactivations using the local
MUTE button press method; SIP mutes only apply to input channels (the “If not SIP
muted” exit condition from State 1 is always true for other channel types). An “Auto
mute on” and “Auto mute off” are achievable in several different ways.
