NON DImming channels are a necessity in modern theatrical lighting. wether to power movers, intergrated lighinting in set pices, fans, or anyhting else you may need. unfortunatly many theaters do not have DMX controllable non dims in house that they can patch to just where you need them. So why not carry your own? no need for a dimmer rack, just a simple inline box fired over DMX, you now have compleate control of your non dims.
