We use an 1200W Yamaha powered mixer PA system and Peavey speakers replacing the old Marshall unit which is now used at rehearsals only. We have wireless mics using Samson systems; 3 Behringer Feedback Destroyers which eliminate feedback from the mics and monitors. A MacGregor power amp to drive the monitors. A Nobels MS-8 MIDI switching device which is controlled by the XP-80 and sends a radio signal to a smoke machine to com on when programmed.
All of this is contained in a custom built rolling cabinet which weighs a bloody ton!
