Dimmer Laws
The user can choose a dimmer law for
each of the master channels. The
dimmer laws determine the relationship
between the control value and the
output value supplied to the lamp.
The laws are characterised for TRIAC
dimmers only. On the Chilli HF ballast
controller, the results obtained may be
different from those shown below,
depending on the ballast used.
Normal
- The standard output of the
dimmer.
Linear
- Suitable for most live or
theatrical situations.
Switch
- Output switches from zero to
full when the input reaches 50%.
Square
- For use with video cameras.
