I'm fairly new to the world of DMX , to date I have only used a single channel DMX controllable fogger with the lighting set-up I have . But , I already want to build my own DMX controllable wash light . I have an ETC Express 48/96 board , The dimmer racks , dimmable circuits hung from battens above stage , and a DMX output onstage . So I have everything I need to use DMX instruments but little knowledge of how they work . I would like to build a wash light with five 250 watt halogen lamps of different colors . I'm not sure of how the AC input and the DMX input interact . I have seen addressable DMX decoders for sale on the electronic hobby kits websites , I'm assuming the decoder would be what distributes the AC current , but what goes between the decoder and the AC input ? Thanks
