One option I have been looking into for a bit as the LFR's DPS unit doesn't have a trigger for it, was to get something like
and then use the 12v trigger line to switch on and off the relays that I can hook up to an outlet that powers the DPS unit along with another set of amps for the height speakers that I have. As this relay has two lines, I could hook it into the split receptical to get two separate 20amp lines.
I didn't think I'd need something like this for the ADA but for the $15 and a small electrical box, it might be the best option.
