40 Chapter 4 Patching channels

Dimmer profiles

A dimmer profile is a variable level sent to a dimmer during a fade that is

related in some way to the percentage of fade completion. By varying the

dimmer profile, you can compensate for nonlinear characteristics or other

time-dependent variations in lighting instruments as well as warm

filaments more slowly to increase lamp life. Dimmer profiles are not

available for 16-bit channels, only for 8-bit channels.

A dimmer may have both a proportional level assigned to it as well as a

dimmer profile.

In the control sequence for a particular channel, the

channel’s level is first modified by the dimmer scaling, if different from

100%. Then the resulting dimmer level is modified during the channel’s

fade by the dimmer profile, if different from a linear profile, to yield the

dimmer’s final output.

The console has 33 dimmer profiles, of which 32 are editable. Profile 0,

the default profile, is a linear profile

and is not editable. Profiles 1

through 9 have preset, nonlinear profiles and are all editable. Profiles 10

through 32 default to linear profiles and are all editable.

Pre-defined profiles

0 - Linear (not editable)

1 - IES square

2 - Slow bottom

3 - Fast bottom

4 - Slow top

5 - Fast top

6 - Full at 1%

7 - Preheat at 5%

8 - Preheat at 10%

9 - Hot patch

See Proportional patching, page 38, for information about how to make the

dimmer output proportional to a scaling factor.

16.

A linear profile is one that has an intensity level directly proportional to the fade

time at all points in the fade time. Thus, when the fade is 50% complete, the

intensity level is 50% of the full value.
