I’ve got an Rotel A12 integrated amp, with CD Player and Vintage TT attached. The amp drives a pair of Wharfedale speakers in living room. Only streaming I do is Apple Music via a dedicated iphone that I connect direct to the A12 via USB or Bluetooth.

Looking to connect from my amp’s pre+out to the Port that would wirelessly drive an Era speaker in another room (or on my deck), however I’d only feed audio to ONE room at a time, ie, if feeding to the Era, I’d have my Wharfedale speakers off on my A12.

This would work…right?  Also…. I’m thinking of setting up a 2nd router, disconnected from internet ISP, so a local, closed WiFi network to handle WiFi network to stream audio from Port to Era…. Is this doable?

This seems like a lot of trouble. Why do you want to block Internet access? How does AppleMusic play without an Internet connection?

There will be a 75ms time offset between A12 output and the ERA. Unless you can simultaneously hear both, this will not be an issue.

The ERA, PORT, and the SONOS controller all need to be on the same subnet. You will need Internet access during setup. It is possible that the SONOS system will need Internet access from time to time. I’m not sure if the system will recover from a power failure or controller reset unless it briefly has Internet access.


Perhaps I’m paranoid about security with these vs a desktop or phone, maybe it’s not warranted and I’ll connect to my regular WiFi.  Completely aware of sound lag, and as mentioned I’d never have a use case of using my passive speaker and Era at the same time.  So lag is a non-issue.  Thanks
