Power down the new Sonos. 

Then fully update your existing system, App and devices.

Once updated and the reboot finishes you can proceede.

Then confirm which system, S1 or S2 your current devices are running, the app has that info under settings.

Power down ALL proceed. Power up the new Sonos. Try connecting with your controller, if it is the S2 controller and is complaining about S1 issues load the S1 controller and try connecting again.

Depending on what you find, the support link (top of the page here) has guidance for sorting any S1/S2 confusion.

The Sonos Connect Gen 1 is only compatible with the S1 app.

Additionally I have a connect gen 1 that is S2 compatible...can I use the connect amp gen 1 as a slave amp to the connect gen 1...which is already successfully set up within my total system?

The Connect (Gen 1) and Connect:Amp (Gen 1) are both S1 only. Are you sure your Connect:Amp isn’t Gen 2? If it is and has been upgraded to S2 and you wish to downgrade it, you can. However you need to see if you have any S2 devices that can’t be downgraded, such as the Roam 2.

If you have devices that can’t be downgraded to S1 you will have to run two systems if you want to use them and the S1 devices. 

Known limitations with separate S1 and S2 Sonos systems

A Connect Gen 1 is not S2 compatible, the Connect Gen 2 is S2 compatible.  If you were to connect the analog line-outs of the Connect Gen 2 to the analog Line-In on the Connect:Amp Gen 1 it would work, but there is a 75 ms delay on the Line-In to buffer the input for steaming.  So it would not be in sync with any other Sonos you wish to group it to.

Downgrade instructions are in the support section here.

Slave? No idea what that is.

The computer programs are not capable of doing much, you need the App and firmware updated to progress.

Thanks Jgatie once again!!!….My Connect 1 is already working in my system (with ethernet) in a room with an amp and passive speakers in my overall system...my main room has my Sonos amp (ethernet connect) with passive speakers...everything works well now….the problem is the current amp with the connect 1 is not efficient, so I replaced it with a connect amp gen 1, as a slave amp, instead of the inefficient one (ohm issues)...can I make this work? Thanks again for your input...much appreciated…!!

As stated, the Line-In on a Connect:Amp have a delay of 75 ms, meaning the audio from the Connect line-outs will not start until the 75 ms buffer fills up.  Played by itself, this is no problem.  If you wish to group the Connect/Connect:Amp combo with other Sonos devices, the audio will he lagging behind the other devices due to the 75 ms delay.
