Line-In encoding
When you have line-in music sources attached to a ZonePlayer, line-in encoding 
determines how the Sonos Digital Music System will encode the data coming in from 
these sources. For multi-room audio, we recommend the Compressed setting. For the 
highest quality sound, you can select Uncompressed encoding instead (note that this 
selection requires more network bandwidth than compressed audio.) For TV or DVD 
audio, we recommend the Uncompressed setting.
1. From the Music menu, select System Settings.
2. Select Advanced Settings
>Line-In Encoding.
3. Use the scroll wheel to select Uncompressed or Compressed encoding, and 
press OK. When Compressed is selected, you will notice a slight delay before the 
music starts to play. When Uncompressed is selected, this delay is significantly 
reduced.
Selecting a different wireless channel
The Sonos Digital Music System selects the optimal radio frequency channel during 
setup. However, if you have other wireless devices using this channel, you may want to 
switch the Sonos Digital Music System to another channel to avoid conflicts, as 
conflicts may cause audio drop-outs.
1. From the Music menu select System Settings.
2. Select Advanced Settings
>Wireless Channel. 
3. Use the scroll wheel to select a different wireless channel, and press OK.
It may take several seconds for the switch to take effect. If you have music playing, a 
short music dropout will occur during the wireless channel change.
