I purchased a T1 Phono SB turntable from Sonos and am trying to connect it to my system to play vinyls.

My current setup has two rooms

  • Media Room (Room 1), is setup with an Arc, Amp, Sub and rear ceiling speakers; The speakers are connected tot he Amp.
  • Patio (Room 2), is setup with a Move that I can “move” around the house.

I connected the turntable to the Amp and tried to look endlessly for this “Line In” to show up, but have not had any luck. I’ve tried both on an Android and iOS.

Need help, before I return the Turntable back to Sonos.

The line-in port and other ports on a Sonos Amp, whilst performing the (slave) role of controlling the rear surround speakers to the Sonos Arc (master) HT device is disabled on that player. If you unbond the Amp from the Arc then you will be able to use its line-in. It will soon become a nuisance though bonding/unbonding the Amp from the Sonos HT setup - so maybe add another Sonos device to your setup that has a line-in port, such as…

You will need to use a Sonos product that has a line-in as follows…

  • Port/Connect 
  • Amp/Connect:Amp 
  • Five/Play:5 (gen2) 
  • Era-100 (requires additional dongle)**
  • Era-300 (requires additional dongle)**
  • Sonos Move 2 (requires additional dongle)

** Note: If any of the above compatible devices are used as a HT Surround, then their line-in port and Bluetooth Rx both become disabled.

Once the TT is connected it can play to any/all Sonos products.

When the Amp is being used as surrounds in a home theater setup, the line-in feature is disabled on the Amp.

Thank you for your responses. This seems a bit odd, that this is how it is setup. Wouldn’t enabling the Line-In as and when something is being played on that input make sense?

Perhaps there’s a sound / electrical reason for the Line-In to be disabled in this setup.

Getting additional components will just make this hobby a bit too expensive. I’ll have to look for a more conventional / cheaper option. :(

The Amp is being commanded by the Arc via a dedicated 5Ghz link, sending sound from the Arc to the Amp. According to Sonos this link is not capable of being used to send sound the other way, from the Amp to the Arc, so the software disables the Line in on Sonos devices used for surround.

If you would want to connect your turntable to your Sonos system using a new device a Sonos Era 100 plus USB-C adapter would be the cheapest option. A used Port or Connect (needs to be S2) or other devices mentioned above would also work.

In theory the 5GHz link could be used for any traffic. Network traffic is after all bi-directional. 

The logic for not permitting the use of Line-In on Home Theatre satellites is that (a) the link fluctuates, idling onto 2.4GHz and periodically scanning all the available 5GHz channels when not in use, and (b) any significant non-HT traffic could imperil the latency of the connection, causing the HT audio to drop if the shallow buffers run dry.
