* iRadio/Streaming Services are output as 16-bit data at the appropriate 
sample rate for the decompressed data. The sample rate will be 32kHz, 
44.1kHz or 48kHz depending on the streams sample rate.

Incoming streams of less than 32kHz sample rate cannot be output over S/P 
DIF /TOSLINK.

For compressed streams the true resolution of the audio is of course limited 
by the encoding. 

For Media content from local drives or UPnP this outputs in its native resolution 
of 16/24-bit, 32kHz 44.1kHz 48kHz or 96kHz with bit for bit transfer.

the CXN needs to build dynamically as you browse content. Good practice 
is to create folders for Artists within which you should have a sub folders for 
each Album which then containing the tracks for that Album. Libraries with 
thousands of tracks in one folder will progressively slow down the CXNs 
media browsing.

For all servicing, in or out of warranty, please contact your dealer.
