It might very well be a setting in the pack itself as you have stated. Not familar with the pack, so when I get time I will get the manual and look it over real quick.
Some dimmers have modes on them. This means that while it is a 4 channel pack, only one DMX channel triggers all four channels, just like the X-Box thing again.
The
Elation DP-640B takes this a step farther. It has a really cool feature that let's you patch each dimmer to whichever channel you would like. Really useful when working with my Hog since it doesn't let me patch multiple channels to the same address (basic function on just about every other console with a patch in it, but not this one
). It can also dim without a console, and panic switches are again really useful for focusing or emergencies. All and all a great product I would highly recommend to anyone.
Sorry for the mini review, just kinda kept coming out lol. We now return to your regularly scheduled forum topic.
