I took a stab at finding an adequate solution for hooking up my new Sonos Port to my Crown D-75A amplifier… it turns out it was easy, not finding help from any provided inbox instructions from Sonos, so I though I would share on the community forum. https://www.nilesaudio.com/product/voltage-triggered-ac-power-strip-FG00242 This $200 product was on eBay used for $9… The 3.5mm cable cost me more than the relay box at Best Buy… I just had to strip one end to the IN terminal and plug the 3.5mm into the Port. I leave my amp switch on, and then play my device (Sonos App, Airplay2, etc.), it activates my amp and I listen… And the after about a minute of dead air from pause or shut off, my amps power turns off. Now I don’t waste power or have to get up and actually remember to turn off my amp… Fear not.
Successful and easy solution for Sonos Port output of 12 volt trigger to external amp.
