Turning the power off on a projector in order to make the room dark, is a very slow and ineffecient solution. It is often time consuming, and turning the projector back on also costs valuable time. Everyone knows that there is no time to waste on power issues when a performance, a show or a lecture is running. You need a blackout to happen fast and efficiently, and get the power back on seconds after. These quick changes are possible with our DMX Projector Shutters.

The shutter is a motor driven flap you can control from the lighting desk. You can alternatively control the Projector Shutter manually for positions and speed as well as pre-program it to shut off the lights at specific points of time during the show, by using it with an External Button.

DMX Projector Shutters or Video Projector Dowsers

Our DMX Projector Shutters or video projector dowsers which they are also called, control the flap by a motor-driven unit.  The flap moves in front of the projector lens in order to shut off the lights coming from the projector, including the so-called "video black" light.

The DMX Projector Shutters come in various sizes and you can connect them to different sizes of projectors. So, whether you have a small, medium or large projector, our projector shutters are applicable. We have different flaps in different sizes (Small, BigMega) that applies to our DMX Projector Shutters. You can mount the projector shutters anywhere you want them, which makes the Wahlberg shutter a very flexible solution.

You can mount the shutter so it fits your existing setup, and doesn't interfere with other scenic elements you have applied in your stage design. We have made it as easy and flexible as possible.
