Projector Dowser Part #: SL-4160 Price: $625.00


Inexpensive digital projectors are used on shows everywhere but they have a problem that is difficult to overcome: When they fade out, they still project light, called “video black”, and this small amount of light is easily visible during a stage blackout. Our Projector Dowser is a simple DMX (or contact closure) controlled flag that can be closed in front of the projector’s lens when you need a complete blackout. An included mounting plate allows a variety of hanging positions to suit your production’s needs.

NOTE: Requires 24 VDC, 250 mA power supply (not included). See drop-down box for options.
