Editing Mixing console (section)

===Mirroring===
Some mixing consoles, particularly those designed for broadcast and live sound, include facilities for ''mirroring'' two consoles, making both consoles exact copies of each other with the same inputs and outputs, the same settings, and the same audio mix. There are two primary reasons for doing this; one, in the event of a hardware failure, a second redundant console is already in place and can be switched to (an important feature for live broadcasts); second, it allows the operators to set up two identical mix positions, one at front of house — where the audio will be mixed during a performance — and the other at some other location within the theater (e.g., with the broadcasting equipment); this way, if the acoustics at front of house are unfavorable, a mix can be programmed at an acoustically better position in the room, and the presets (on the faders and knobs) can be accessed from the front of house console during the performance.
