DMX to analogue decoders are still to be found in numerous theatres and TV stations around the world. The ideal (and in many cases the only) way to interface older dimmers to DMX - oh happy days of multicore cable, Socapex and the pin matrix!
A while ago XTBA installed 1,632 channels of DMX to analogue decoders in a TV studio. Some years later they needed some splitters but did not know of XTBA - until it was pointed out to them that they had two racks with 34 XTBA decoders in the basement. They had switched these on and forgotten about them for six years - they then bought the splitters from us without further hesitation!
