S1 Pro system experiences running on battery power
Other than experimenting with my Bose S1 Pro early on, I have not publicly plugged mine in to AC power or mounted it on a pole in any public performance. It's either been flat on a table or tilted up on the ground and always on battery power. Setup and tear down time have been greatly reduced. My Behringer 1002B battery powered mixer, along with stomp box preamplifiers for instruments allow me to run an entire band through mine, including a U-Bass. The clipping signal LED is very useful in keeping the sound loud and clean.
