Sonos Port is new updated version of Sonos Connect (aka ZP90)

Connect Port to your traditional stereo to stream music and more. Enjoy control with the Sonos app or Apple AirPlay 2, and easily expand your sound system to more rooms.

• Flexible. Features analog, coaxial digital audio outputs.
• Line-in. Plug in any device you desire.
• Play your amplified turntable through your Sonos system.
• Stream your CDs and LPs to Sonos speakers in other rooms.
• Streams over wi-fi, not Bluetooth, so the music never stops – even if you get a phone call.
• Connect Sonos to an Amazon Echo or Dot, then simply request the music you love.
• 12V trigger turns on your stereo or receiver automatically when a signal is sent so there's no extra steps or remote needed.
