SONOS USER GUIDE
• You want optimal performance with home theaters.
• You want to produce the highest quality sound for your Sonos system (this selection requires more
network bandwidth than compressed audio.)
Use Compressed if:
• You are connecting more than 4 rooms wirelessly.
• You are in an environment with heavy wireless interference and are experiencing dropouts.
To change the line-in encoding setting, tap > Settings > Advanced Settings > Audio Compression.
