Power On/Off Devices without 12V Trigger

[WiiMer SJ]

Are you using this for your pro and pro plus? I was wondering if you could gang the trigger wires together before plugging into the power bar. I have three pro plusses and i am looking for a solution where I have a single power bar that all the amps are plugged into. I don't mind if they all turn on and off when the power bar is triggered.

I am currently using one pro plus to trigger one power strip.
Doing what you suggest is possible, but would require more complicated circuitry. I have looked for a consumer grade product designed and built for your application, but have yet to find one.
