Use Line-In on Sonos

This article provides information about line-in and how to use it on your Sonos system. Line-in is an audio input available on some Sonos products that allows you to connect a device with an audio output (such as a CD player or turntable) to play out of your Sonos system.

Standard Line-In connections are rated at 16-bit/44.1KHz. Additionally, the Sonos Line-in Adapter, Combo Adapter, and Ace Aux Cable also convert analog audio to 16-bit/44.1KHz.
