Triggering my PA amp

Hi
I used to use a one click extension lead to power on my hidden pa amp for my subwoofers
My av amp used to be plugged into the main socket so when that was turned on it used to power the other sockets to my pa amp

I’ve now switched to a minidsp pre amp this will not power the other sockets on when it’s turned on presumably because it has a 12v power supply

Anyone have a work around I can use to power up a av amp using something with a 12v power supply

Thanks

It's probably because the power draw for the miniDSP isn't enough to trigger the master/slave circuit. I've had the same problem and it's a bit annoying.

You can find USB-triggered sockets that accomplishes more or less the same thing as the master/slave.

Either add a small regulator to the miniDSPs 12V supply to trigger the 5V USB circuit, or simply use a spare USB phono charger that is switched on when the miniDSP is switched on to trigger the main power strip. Not quite as easy as the original solution, but with a bit of thinking it should be fully workable 🙂
