Run an extension cord from the conditioner to the speaker, get a "computer"power cable from the wire box, plug that in the speaker, plug the other end into the extension cord...dig out the right length speaker cable run it from the board past the stand that the lead singer so proudly placed in your way, past the lead singer who can't figure out what to do...plug that into the speaker... Whew, I need a break from all this excitement...
Then do it all again for the other side...then again for stage monitors.... Or, get yourself a set of these marvelous Siamese Twin cables. My setup time was cut in half. It's just the right thing to do for your powered speakers.
Why I waited so long I'll never understand.
On the down side, they are bulky has heck, I need to get a bigger cable box.
