2 Ports to trigger one multi-channel amp

Before I break something, I want to know if this will work as intended.

I have two zones, one Port for each.

I have an older but great sounding 5x 200w Outlaw amp I want to use. 2 channels for zone 1, and 2 channels for zone 2. The 5th channel won’t be used.

The Outlaw amp, like pretty much all home theater amps only has one 12v trigger input.

Can I combine the two Sonos Ports with a Y cable to power the Outlaw amp? That means that if I use both zones at the same time, the amp will be getting two 12v inputs at the same time.

thanks,

~Jay

Sometimes when you interconnect a bunch of audio components together some current flows in the signal lead shields that causes hum. Relays would keep these shields isolated. In your case I assume that you’ve already hooked everything up and there is no hum. Therefore, the diode scheme is no risk in this setup. If there was a hum risk, the relay scheme would eliminate that risk. The relay scheme is more work to fabricate. Besides I have a bag of 1N4004’s leftover from previous projects.

Couple probably minor points. Hard to read the markings on a relay wrong and put it in the circuit backwards, also unlikely to be damaged if you get the plugs in the wrong sockets.

Diodes are probably going to work fine for this.
