I'm a small nightclub (300 capacity) owner doing the lighting myself. Just got two accu spot 250 pro lights, was all jazzed then bummed. I like to run my lights in audio mode with just a blackout switch. Was dissapointed to find no input for such a switch. I ran the lights, but the focus is so lame they look sad. Used a elation 192 to run lights in audio mode (ch 14) but could not use the focus (ch 10) whats up with that? Anybody got an idea to remedy my problems?
