We are about to purchase some more dimming capacity. We are looking at an NSI 8-channel pack - due to our venue limitations we need something portable that is not hardwired. We have an available 50A circuit with a big appliance-style plug - I'm not sure exactly what it is. The problem lies in my ignorance. I don't know what I need in order to successfully get the dimmer pack wired with power cable (they said it does not come with one) and make an "extension cord" of sorts to run the power from the wall to the pack. I don't want to hardwire a very long cord into the pack for portability's sake. If anyone has any insight into what kind of cable and plugs I nedd, it would be much appreciated. Thanks!
