I just added an MGE Pulsar EX15. It handles 1,050 watts max output. The battery is small. I think its something like 8 minutes at max output. But that's plenty of time. Its a true sine wave double conversion unit (the Smart APC is not). The cool thing is its lite enough for live sound and, man, it has made a nice difference in sound. I run a pretty clean system, but can tell the difference in noise floor and the lack of fuzz, buzz or his in the system. About $650.00, and well worth it.
I follow the road less traveled, but now, where the hell am I?
