The only thing I can add though is that unless it is an UPS (battery backup) also, then it will not take care of low voltage drops. The problem with an UPS though is they are very heavy to carry around because of the battery. Mine here at home kicks in quite a few times a week because of voltage drop outs (old wiring and too small a transformer on the pole).

Low voltage may or may not cause damage as much as spikes, but it can cause problems with the computer's operation. That said I would say that for you two, at least for the time being it would be best to leave off using the BA. Hoster does have the capability to import those MP3 files you use for the BA and playing them from the playlist too. That is what we do for 15 - 20 minutes before show time.
