"Hard patch" refers to plugging a circuit into a dimmer, with some type of patch panel. Dimmer Per Circuit systems do not have this. Inserting a fixture's plug into a circuit's receptacle is known as "plugging." "Soft patch" refers to assigning, on the control console, one or more dimmers (now called "outputs" to account for devices other than dimmers) to a control channel. "Proportional patch" is assigning dimmer(s) at a specific maximum level to a channel. (Also known as "Scaling Factor" on some Strand consoles.) "Pin patch" refers to patching a multi-cable circuit into a dimmer of a Touring Rack, and happens inside the rack's Patch Bay. [On old R&R Analog consoles, dimmer-to-channel or channel-to-submaster assignments were often made with small pins, which was known as a Matrix Patch or Battleship (ala the "you sunk my Battleship" game) patch.] "Fixture Patch" is assigning automated lights to the proper DMX address in the console. "Repatch" is the process of replugging a dimmer or circuit during a performance. This is done to maximize the use of available dimmers. Example: Unit A is used only in cue 4, unit B is used in cue 10. Upon completion of cue 5 unit A is manually unpatched and unit B is patched. Thus one dimmer may be used for multiple specials. "Hot patch" may be a verb meaning to plug live, while the circuit is energized; or a special receptacle on a retractable-cord patch panel or dimmer rack that is always live. Not to be confused with the similar but different hot pocket.
