I am a home remodeling contractor and have volunteered to help add diming to par 38 cans used in the front of my Church (18 lights). I would sure appreciate your help. I am well versed in residential electric but new to DMX. We need to be able to control the lights at the older peoples service with the current wall switches which turn on the 3 circuits for lighting the front stage area of the church. But at the contemporary service with a band we want to be able to dim the lighting with a dmx controller and basic 4 channel dimers plugged into the switched outlets and then the light cans plugged into the dimers. My Question is can we work the lights by switching power on and off to the dimers with the wall switches and not doing anything with the dmx controller? Do the dimers come back on to there last setting when power is cut then turned back on. Do the dimers have memory? or must the dmx controller send a signal to turn them on each time. Thank you in advance for any help. Guy I
