I am going to be using a Sony STR-AZ7000ES receiver in a true 13.2 surround sound setup, with a Sonos port lined into 1 of the 3 @ 12V trigger inputs on the Sony. I mostly work in networking over that of A/V, but still do a ton of A/V work throughout the year. 

That said, sorry if this is a novice question, but what type of cable is used to connect the Sonos Port to respective input on the Sony receiver? It looks to me like it’s just a 3.5mm cable? Or is it something else?

Thanks!
