Both AC Line & Speaker Cables are "wire wrapped together" for convenience, ( Gary taught me that)

....who wants to carry a big heavy boxy powered mixer around + the speakers?. I only use a mixer on big 4hr jobs, more players, singers etc, or DJ'ing. For small gigs just plug the powered speakers into the KB & your good to go...simple.
Question for you, Donny. Doesn't wrapping AC and speaker cables together cause hum?
I've always kept mine separate as much as possible, even to the extent of making sure that when they do cross each other, say, on the floor, I make sure they cross at right angles to each other. Maybe this is real old school thinking, but old habits die hard.
