A:Answer No; you can setup a SONOS system using only one or more PLAY speakers. Using the iTunes, Android, or PC applications you can stream many music services, and your local music library to the SONOS system.
The Connect gives you two added capabilities.
- The Line Out can connect to your existing stereo system, letting SONOS stream to your system's speakers.
- And, the Line In allows any analog source to play through the entire SONOS system. For instance, the line out of your receiver could be connected to this input, and any record played on your turntable can play through the entire SONOS system. I have an Amazon Echo Dot connected to the Connect analog input and have voice control over what songs play through the entire SONOS system. Note, for the voice control with the Echo Dot you will need a compatible streaming music service.
