The houselight panels are typically used like this:
A stagehand walks in the auditorium door and presses the take control button at that station. The
house lights come up. Climbing into the tech booth, the stagehand then takes control at that station
and dims the lights. Leaving by the backstage exit, the stagehand presses the off button there, turn-
ing off the lights.
DMX stage lighting controllers may also be used to control house lights on the DMX input to the
house light dimmers.
IN CASE OF TROUBLE
Consult the wiring diagrams at the rear of the manual, which answer many common questions.
The chief cause of trouble is a wiring error, particularly on the common, +12V, or clear lines. Keep
the same color wire in the same terminal on all panels. Do not swap positions or short the wires. The
common wire travels from panel to panel and ends at the dimmer pack; if missing, no panels will
work, some panels won't work, or some channels will dim as others are raised. The power supply line
must be connected to all panels and either the dimmer pack or wall transformer; without it, some or
all panels will be stuck off (neither LED will glow). The clear line must be connected to all panels; dis-
connected, some or all panels will not take control from the others.
If all lights flicker, the power supply from the dimmer may be inadequate. Swap in a "wall wart" type
power supply transformer of +12VDC 500mA or more.
A broken slider will cause one channel to flicker or be stuck off at that panel. It should be replaced but
may be treated temporarily with WD-40.
If unexpected lights come up, check that the control wires go to the correct dimmer inputs, that some
dimmer inputs haven't been incorrectly looped together.
If one to four channels are stuck off at any one panel, try swapping the two LM324 chips to see if the
problem moves from one channel to another.
All chips should run cool or slightly warm to the touch. If any are hot, disconnect the panel and return
it to the factory for repair.
The blue trimmer adjusts the output voltage and should not be adjusted under most circumstances. It
has been factory set for +10VDC output.
