B Dimmer Curves 56
Modified Square law curve
A standard square law curve may overcompensate for infrared loss, resulting in “steppy”
response to incremental control changes at low levels. ETC’s modified square law curve
applies a second multiple to the standard square law curve for more uniform response to
control levels changes across the entire range of dimmer output,
Sensor 2.0 curve
The Sensor 2.0 curve is the previous version of ETC’s modified square law curve. It
provides backwards compatibility for shows created using earlier versions of ETC
equipment and familiar response for designers who prefer the earlier version.
