If you're not inclined to do it yourself I have seen power strips that have this function built in but IIRC they are very pricey, circa $100 or so.
I had the materials I needed already but here's what you would need from Radio Shack:
1) 275-248 12V Relay 10amp AC load
* Coil rating of 12VDC
* 400 ohms
* Body size of 9/16x5/32x5/8"
The 30mA coil is important as the 12v triggers combined only source 50mA. The 10A is also important if you are going to hook up some loads. I use mine for my subs and some back lighting.
2) 274-251 1/8" Mono panel mount jack
Note: This is an open connector. You may want to use an insulated type, especially if your power strip is a metal case as this would short.
3) 1/8" male to male mono cable to connect to the 12v trigger jacks.
4) A power strip with some room inside to fit in the relay and the plug connector.
Open up the power strip and find a good place to fit in the relay and a place to put the jack. Drill a hole to accept the jack.
Cut or desolder the incoming AC black wire ahead of the 120v receptacles. Connect (I recommend soldering) one side of the black wire to the NO pin on the relay. Connect the other side of the black wire (going out to the receptacles) to the common pin on the relay. That's it for the AC line.
Solder a wire from the 1/8" jack ground connector (this is the one that contacts the side of the plug) to one of the coil pins on the relay. If the coil pins are polarized, connect to the "-". Do the same with the tip connector to the other coil pin, this is the +12v incoming. Most DC relays aren't polarized. That's it for the DC.
I super glued the relay to the power strip case. Close it up. Plug in the AC and run like hell. If nothing happens good. The AC receptacles should be off. Connect a 12v trigger with the 1/8" cable on the back of the AVR to the connector you installed on the power strip. Go into the Pio setup menu and select an input, on the second page should be your 12v trigger assignments set it to "MAIN". The 120v receptacles should be on when you exit setup. That's it. $10 and a 1/2 hour.
Note: If you get a 12v trigger error on your display you have a short in the 12v wiring or the relay coil is pulling more than 50mA. After you fix it, you must press standby on & off to reset the circuit protection inside the AVR.
Another note: My technical writing skills or lack thereof not withstanding if the above doesn't make any sense or you can't figure this out yourself you're better off not doing it. It's easy to do and it's also easy to screw up for the un-electrical inclined. Have someone do it for you or buy the ready to go power strip.
TBS, good luck. Mine works great and since the built in 120v switched outlets in AVRs typically only carry an amp or less this adds more functionality.
