A:AnswerCheck the interfaces with your LG soundbar. If it has Bluetooth, you should be able to connect as with any other source. I have my Sony turntable connected with the RCA phono jack to my older Klipsch soundbar and it works well, detecting the source, be it my TV (connected via another interface) or the turntable.
A:AnswerThe Sony turntable only works with the new Sonos Move Bluetooth/WiFi portable speaker. That is what I have and it works great! In fact the Bluetooth range is very far and I can play a record in one room and take the speaker onto another floor to listen. Highly recommend having that speaker with this turntable, the range and sound is incredible.
A:AnswerI believe you'd need to buy a Sonos amp/connector. (Not sure what Sonos is calling it these days) I was not able to connect it directly to my Sonos 1 or 5. My Sonos system works on wifi and this turntable is able to connect to Bluetooth speakers. I have also the turntable up with my receiver, which is not connected to my sonos speakers.
