Sonos port1us1blk Streaming Audio Adapter Matte Black

Product Description

The SONOS port1us1blk is a network streaming adapter that bridges legacy stereo equipment with modern digital audio platforms. Designed for integration with existing amplifiers, receivers, and preamplifiers, it supports AirPlay 2, multiroom audio streaming, and a wide range of third-party streaming services. The unit ships in matte black and connects to a home network via wired Ethernet or Wi-Fi. It includes a digital coaxial input, RCA line-level input and output, and a 12-volt trigger output for automatic amplifier power control. Licensed HVAC, AV, and low-voltage installers regularly incorporate this device in whole-home audio projects.

The port1us1blk is suited for residential installations where a client wants to add network streaming capability to an existing stereo system without replacing the amplifier or speakers. It works with turntables equipped with a built-in phono preamp, CD players, and other analog sources via RCA line in. Supported streaming services include Apple Music via Siri and AirPlay 2, Spotify, Amazon Music, TIDAL, and Pandora. Multiroom functionality allows audio to be synchronized or independently routed across multiple zones using the Sonos app.
