When the Fives are being used as surrounds, it disables the line-in ports. So in order to connect your turntable, you would have to unbond the Fives as surrounds from the Arc first and then create a stereo pair with the two Fives.

Every time? What if I turn off the TV… will the Fives recognize the line-in?

Yes, every time. Turning off the TV won’t make any difference.

Thank you.

OK, I did that. Removed the Fives as surrounds, plugged in the Line In to the L Five. Add the R Five as a stereo pair and select it as the R speaker, sound coming from the speaker sounds terrible. When I select the L speaker as the R (facing the speakers), basically the opposite Five playing the tone… it seems to sound OK but when I get close the L Five sounds terrible. I’ve tried unpairing them over and over and it cannot figure out which is R and L and it continues to sound like trash. Set everything back for the television. I have absolutely no idea what’s going on. Leaving it be for the night. Signed, super frustrated.

Does your turntable have an internal preamp? Is it on?

Have you tried to Adjust Line-In settings ?

Yes, I have a preamp and it is on. 

The thing is before I got my Arc and moved my Fives to the rear as surrounds the turntable with the Fives as a stereo pair worked just fine (even with the Sub). Ever since the change it’s been a nightmare.  I’ll experiment more, maybe tonight,  and report back.

After a change like this you do need to Trueplay your system again.

Likely, there is a physical issue with the turntable.

As a quick check, make sure that the cables are fully seated.

You can use the SONOS balance control to identify L/R.

I solved it… bought two One SL’s for the surrounds and moved the Fives for a dedicated stereo pair on the turntable.
