how to trigger my sub amp when main powers up.

Hi Grady,

i have never done it...but a lot of equipment comes with a 12v trigger...which apparently allows you to use a switch to automatically flip on the system. Additionally, certain PS audio powerstrips actually bring on power in a certain order down the strip...so if you plug your components in the right order, they will turn on sequentially just by turning on the PS Audio power strip.

good luck and pls keep us posted.

12v triggers work amazingly well, my system fires 5 componets with 1 button thanks to a 12v trigger. Either 12v to 12v "handshakes" done via minijack or if not capable use of a powerstrip can do this.

If your trying to get the remote to learn the power button for the other, you may have to program to a button other than a power button. A lot of learning remotes don't learn the power on/off on the same power button itself. I'm assuming this is what your trying to do since they're both remote receivers. If it doesn't work, you may have to use both remotes. The subs must be easy to drive if your using a receiver to do that. Page 26(AVR3600) may help for learning the other remote codes. Its surprising they both don't turn on with the remote.

Dont most subs "wake up" when a music signal is sent? Just leave them on is also what most do.
