CHAPTER 5:
Setting Up the Soft Patch
What is a Soft Patch?
The term "patch" refers to a table that shows which dimmer numbers are
controlled by which control channels. The dimmers in turn feed electrical
current into the circuits that connect to lighting instruments. In some older
lighting systems, the assignments of instruments to dimmers are altered
through a "hard" patch. A hard patch is a hard-wire method such as the
"telephone patch" or a "slider patch" used to connect a circuit to a dimmer.
Older lighting consoles have each dimmer controlled by its own slider. Newer
control consoles such as the Encore series, allow you to control a number of
dimmers with one control channel (a "soft" patch). If a theater uses a hard
patch from the circuits to the dimmers, and a console with a soft patch, there
may be an association of up to three numbers for each lighting instrument: a
circuit number, a dimmer number, and a control channel number.
