I do sound and lighting for my high school and we have an ECMUX system. We use a DMX board that runs into a protocol converter to get it to ECMUX. We have EC Quad dimmers. They are 4 channel dimmers. They look like this http://www.johnsonsystems.com/parts/QD-Q24KW_large.jpg
I am having some problems with these dimmers. Some channels wont turn on some will not turn off. Some dim but do not turn all the way off. One of the dimmer pack's Ramp light wont turn on. The Drive lights also do not come on when pushing the fader up. The line and load lights come on but no ramp or drive. No lighting fixtures on that pack turn on. Any idea of what the problem may be? Firing card? SCR? I am up to somewhere around 10 channels that are not working properly plus the one dimmer pack that has the ramp and drive problem. Any ideas?
