For gigs, I would not use this unit because there are too many parts to set up, and the build quality of the satellites is cheap. The volume output is only adequate for a living room atmosphere, not much more.
Like some others here, I made some modifications to the sat wiring of my Z2200 and mounted them on a board to make for easier gig set-up ... I used the Z2200 for many gigs including a fairly 'strange' set up in a country club, and covered two rooms nicely ...
