My receiver has a 12 volt trigger out x2. I have run RCA wire in my walls to where my amp will be.

Can I use a headphone to RCA for my 12v trigger?

Yes, that is a common way of wiring it. The trigger typically is an 1/8" mono jack but can be adapted to any two-pole wire.

so a mono or stereo 3.5 plug will work?

any suggestions on a 20 amp power strip or other device that will accept a trigger input?

Yep.

I am using mono 1/8" jacks to bare wire with a Niles switcher.

I don't believe it is rated for 20 amps, but I have used several of these with various pro-amps and have never had an issue. I think they are 15 amp units.

You can buy something or build your own:

WOW- thanks a ton! I just got my balanced mini wired up for power and RCAs on the input side. Ordered some XLR plugs for my amp etc.....

Thanks, again! I will investigate this and go with what works best for me!!cool.gif

Would something like this be good for the relay end of this thing?

I know I know.... I could simply buy the relay and wires and etc etc..... but I am tired. So tired. I just want my amp to turn off with my receiver.

IF I can buy this and splice it into one of my 3-5 20 amp receptacle boxes and be done well..... all the better.

Seems this box would also fit right inside the big honkin' empty space I have compliments of class D tech. Might be able to just snip, wire, and add a 1/8" jack to my amp.
