5.8.3 Dimmer and console set profiles
Many modern consoles, such as the ETC Expression and Obsession, have
the ability to set dimmer profiles themselves, assuming a linear response
from the dimmers. It is certainly more convenient to set dimmer profiles at
the console, where the information can be stored with the other informa-
tion for each show, but there is one important distinction – non-dims.
Please note that, when using non-dim profiles to drive capacitive loads
such as motors or ballasts for discharge lights, it is desirable to pass
through as much of the mains wave-form as possible to the load. In some
cases, particularly where the output scale voltage is significantly below the
supply voltage to the dimmer room, setting a non-dim profile at the con-
sole will result in a significantly chopped wave-form being seen by the
load.
Smartrack does not regulate non-dim or hot profiles, so by setting the non-
dims at the rack, a full output wave-form can be guaranteed for sensitive
loads.
5.8.4 Setting profiles
a)
If the control panel is locked (enter LED off), press
enter
for three sec-
onds to gain access.
b)
Press
dimmer
to enter dimmer mode.
c)
Select all dimmers by pressing
▼
, or select an individual dimmer to
set with the
▲
and
▼
keys.
d)
Press
profile
to display the dimmer profiles menu, and scroll to the
desired profile for the selected dimmer(s), using the
▲
and
▼
keys.
The
enter
LED flashes, indicating that the profile displayed is not that
recorded in memory for the dimmer(s).
e)
Confirm the choice of profile for the selected dimmer(s) by pressing
enter
. This sets the control panel back to dimmer mode, for the selec-
tion of the next dimmer to be set.
f)
To exit without saving, press
dimmer
or
