ETC sensor+ CEM+ - Modified Square law curve; Sensor 2.0 curve

Dimmer Curves 75
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.
