STEP 2 – Setting up the USB source
The USB interface can be connected to a Windows
TM
Vista/ Windows
TM
7 or XP (SP2 or later) PC,
Mac
TM
OSX (10.5.4 or later) systems or a sound server, running software to generate PCM data.
If you do not want to use a USB source,
go to STEP 3
.
A word about Music Playing Software
There are countless programs that can play music on Windows
TM
PC and Apple Mac
TM
OSX systems.
Unfortunately, not all of them present the data completely unprocessed to the USB ports. For
example, Windows Media Player re-samples all data to 24 bits, albeit at the original sample rate,
whilst iTunes rate converts data as necessary to the output sample rate set in the OSX Audio set-up
panel.
With such a proliferation of playing software, and with updates being issued daily, it is impossible for
dCS
to be fully up-to-date with the behaviour and performance of all programs. If you have questions
or problems, we would urge you to take them up with your software vendor. What we will say is that
different programs operate very differently and it is well worth finding out exactly how your particular
program processes the audio.
One particular problem that has been identified and is worthy of note, concerns the popular iTunes
program when running on Windows systems. The default output word length is 16 bits and must be
changed to 24 bits for correct operation. To do this, click on
Start
>
Control Panel
>
Quicktime
.
Click on the
Audio
tab of the Quicktime panel and select
24 bit
in the
Size
field of the
Sound Out
section.
Selecting the

Mac
TM
