Battery backup question
Just answering the question from above about what is a battery backup.
The good ones are essentially a really heavy power/spike/surge strip with a battery incorporated that allows a battery to supply electricity to usually certain plugs on the strip in the event of power failure long enough to shut down a computer or other critical system safely.
The added advantage of many of these is that they operate as a power conditioner as well by running power through the battery. The battery sends out a very stable amount of electricity and prevents fluctuations. The fluctuations may be what is causing the hum in the system.
Other possible options could be bad or insufficient sheilding on power and audio cables that are too close to each other or something is wired wrong causing a ground loop.
I recommend a power conditioner to anyone using a PA system for any purpose. Prevents problems and might even keep equipment from wearing out as soon. I wouldn't recommend running an amp or any heavy draw items through a battery backup. I have had experiences with the batteries failing due to excessive power draw.
By the way, I'm glad to hear you got running Lloyd. I replied to your email, by the way. Sorry it took so long.
