A:Answer This unit will work to connect a turntable to a Sonos system, as long as your Sonos device has a physical line‑in (like Sonos Port, Sonos Amp, or older units with RCA/3.5 mm inputs). The PP444 converts the low‑level phono signal from your turntable to a standard line‑level output that Sonos line‑in expects.
