any decent 12Vdc power supplies that can be used as a 12V trigger?

I went online and purchased a 12Vdc power supply to use as a trigger plugged in to a smart plug. I noticed after trying it the 12Vdc power supply was actually putting out 17,4Vdc not 12 and also noticed when shut off or unplugged it takes a while for the supply to shut off/ discharge. Anyone have 12V trigger power supply suggestions? 

Thanks

Your amp will work, even without anything connected to trigger input.  Yes, amp turns ON with the presence of +12V, but this voltage is already there (pulled-up internally to 12V).  Try shorting this input to GND - it will turn your amp OFF while removing short will turn it back ON.  All you need is switch.

I just discovered my WiiM pro has a 12V trigger, going to try a cable from WiiM to amp.

I also discovered by e-mailing Micromega, Thier triggers are labeled backward due to a manufacturing issue, so I was plugged in to the output instead of the input. Waiting on my 2.5mm to 3.5mm trigger cable to come in tomorrow so I can try it with the WiiM Pro.

Got the cord for the WiiM pro from Amazon and it works great. I believe a switched mode 12V power supply would work with the smart plug too, the power supply I got probably would work but it takes a while to discharge so the voltage drops enough to shut the amp off. I never left it on long enough to find out.

More to discover
