Connecting turntable to Sonos Connect to beolab B&O

Hi @chrime65, thank you for reaching out and welcome to the community.

I would like you to elaborate on the setup and what we’re trying to achieve.

So, we have a [turntable] line out > line in [phono box s] line out > line in [Sonos Connect] line out > line in [Amplifier/Reciever] with the [Beolab speaker]

and you want to also play on another [Sonos Connect] line out > line in [Amplifier/Reciever] with the [2nd Beolab speaker]?

If this is the case, connect the Turntable to one of the Sonos Connect and group the other Sonos Connect in the Sonos app.

How to group: Room tab > Select the Sonos Connect connected to the turntable > click group > add the other Sonos Connect > hit done.

Then, select your audio source. Anything you select for the group will play on all speakers. 

If you have other concerns, feel free to reach out.

Hi @chrime65, thanks for the update.

We checked that the Line-out is working fine for the Connect while playing Spotify.

Now, I want you to connect the speakers directly to the Phono Box S.

So, we can test if the Phono Box S is producing the Left and Right channels. 

If it’s working, we’re going to test the Line-in of the Connect.

Update us about your findings.

Hi @chrime65, thank you for the update.

Thank you for testing the Phono Box S, I would like you to clarify how you did the test since it’s working.

For the Sonos Connect, I would like you to do a Loop-back test.

Connect the Line-out of the Sonos Connect to the Line-in of the Sonos Connect with an RCA cable.

Play any music service on the Sonos Connect then select another Sonos speaker to play Line-in as the audio source.

If you hear the other speaker playing, the Line-in is working.

If not, I would like you to take a diagnostic; so we can take a closer look. 

Here’s how to take a diagnostic: Settings > Help & Tips > Submit Diagnostic and reply with the confirmation number.

Update us with your findings.

Hi Kyle,

The test of phone box = 1/ I connected turntable to phono box s and then connect the speakers directly to the Phono Box S.,

both speakers worked, this way i don’t have a volume control.

2/ I also did a second set up with a B&O beocenter 2 (turntable>phonobox>beocenter 2>sonos connect) , both speakers played

Result of the loop back test = i hear other sonos speakers but first at a low volume, and then after a while volume was ok

diagnostic is 667300178

Hi @chrime65, thank you for the update.

The diagnostic does show the connect detecting the Line-in loopback test.

It would seem like we have a bad RCA cable; if the bad channel moved to the other side when doing @buzz ‘s test. 

Try using another RCA cable to connect the Sonos Connect with the original setup. Turntable > Phono Box S > Sonos Connect > Speakers.

Update us with your findings. 

Hi Kyle,Buzz

thanksalot for helping me out,

i’ve been testing things with other rca cables, turned out there was a problem with two cables, that’s what got me confused,

however it seems that the connection with the rca cables stays a bit delicate , for now i got it working

Thanks!!!
