12v trigger question

[benjamj]

I know there have been several threads on 12v trigger issues, so I hope you will indulge me. I have an Onkyo receiver with pre-outs and 12v triggers for 2 additional zones. I am using an old 5-channel receiver to power those 2 zones, and have dedicated 2 channels per zone. The old received lacks a 12v trigger input so I am currently turning it on and off manually. I'd like to use a triggered power strip to turn it on when one or both extra zones are activated. My question has to do with wiring the Onkyo triggers to the outlet strip.Could I just use a Y-connector of some kind to feed the 12v output signals from the Onkyo to the single 12v input of the power strip? Would this provide an appropriate signal when one or both zones is activated? Or do I need something more sophisticated to prevent damage to the Onkyo and/or make the outlet strip work correctly? The 12v triggers on the Onkyo have different current capacities, one can generate up to 250 mA and the second up to 50 mA.

Thanks in advance for any help.

You will need something betweeen the two outputs. Easiest way would be two diodes, each in-line on the 12v+ lines. This would let 12v flow towards the power strip, but not back towards the other 12v trigger.

The biggest question is whether your receiver will automatically turn back on after you have power removed for a period of time.
