Revolution Shutter Module FAQ

Why do my new production shutters feel more responsive than earlier demo versions?

This responsiveness and smoothness is a result of the effort we have put into getting a production-ready Shutter Module.  The "sandwich" of metal plates that makes up the shutter device has been incrementally improved every way possible for low friction, reliability, and accuracy.

Why is the shutter so LOUD when you power up the fixture?

This is the sound of all motors driving all of the shutter blades to their limits, several times each, to "home" or calibrate the shutter module.  All moving lights are relatively noisy upon power-up - and the Revolution is no exception.  If you want to minimize this noise for demos, write a "power down cue" for each Revolution that does the following:

In/out parameter (channels 24,26,28,30) at 50%
Blade angle parameter (channels 25,27,29,31) at 100%.

Go to this cue prior to shutting down your Revolutions at the end of each day/session/demo - whatever. The next time the Revolutions are powered up, all of the shutter blades will travel their full range to calibrate.  This minimizes the time of "clattering" in the calibration process to about 4 seconds.

What is this counterweight plate that I get with every Shutter Module?

It's very important!  The shutter module requires a counterweight on the other side of the yoke pivot so that the Revolution is balanced and moves properly.  Don't forget the safety screw that goes into the counterweight plate to capture it in the scroller.  Safety first.  If you put a top hat in the accessory slot, it provides enough weight so the counterweight plate is not required.
