Sonos automatically sets the best Audio Compression level for your system. However, you can adjust these settings using the following guidelines:

Compression setting



Automatic is the default setting for all Line-In products and is recommended by Sonos. Automatic allows Sonos to switch between uncompressed and compressed depending on the performance of your network and Sonos system.


Uncompressed uses the WAV format which provides higher quality audio. Uncompressed audio may put a lot of strain on your network, especially if you have a lot of Sonos products. Use uncompressed if you want the highest audio quality for your Sonos system.


Compressed uses the SBC codec which reduces the quality of the audio but puts much less strain on your network.
