Wahlberg DMX Projector Dowser / Shutter
Blocks waste light from the video projector.
Simple and easy solution with a motor-driven flap.
Direct control from the lighting desk.
The shutter is programmed as a conventional lamp and added to the cue list.
How it works:
The shutter is mounted on top of the projector, so the flap can be turned in front of the lens to block the light from the projector.
The flap is mounted on a motor controlled by a DMX signal from the lighting desk.
The shutter can be programmed as a normal light fixture and added to the cue list (or the like).
The shutter is easily mounted, as the motor part weighs only 300 g (10.5 oz).
