Thanks for your reply!
I'm thinking a long the same lines with regard to streamlining the band set up. I don't even bother with the lighting mixer and just have them set up on a slow colour change. That said, a band I was in years ago had a foot controller which was great for killing the lights at the end of each song and then bringing them back on afterwards. I'm not sure if it's possible to run one of these foot controllers without a mixer unit as well.
Do you think a single 7Q5 on top of each speaker would provide enough light or would you recommend 4 as a minimum?
You'll have to send me a link for the ones you bought as the ADJs were £75 on Amazon when I checked.
