Default Power Conditioning

Load is a 32 channel sound mixer for live performances and some amplified speakers. It's all run on one 20A circuit but I'd guess it's pulling a little more than 20A. Let's assume 25A load. 120V.

This system moves around to different events & venues (small concerts, weddings, whatever) so there is no control over the quality of the power coming from the house.

Looking to isolate any noise which may be present on the circuit and to protect from under voltage & momentary outages or surges.

Would just a good quality pure sine wave UPS do the job?
Anything in particular to leans towards or to avoid?

Thanks!

I wonder if an isolation transformer and a portable GFCI might be a good way to go.

I think the problem with the UPS is you don't have the ground isolated.

The UPS would take care of dips and spikes, but wouldn't isolate the system from ground noise. Maybe a combo of a UPS and isolation transformer. There are plenty of power conditioners commercially available.
