Basic setup with a PC
•
Connect one of the computer’s USB ports to the
USB1
port on the player’s rear panel.
To select the
USB1
port, either tap this button on the app’s Home screen or press the front
panel
Input
button repeatedly until
USB1
is displayed.
If this icon is not displayed, open the Menu and select
Unit Settings > Sync Mode > Master
Mode
.
This is the player’s default
Sync Mode
for the USB and Network interfaces. The player does not lock to
the source clock, but uses the player’s internal clock instead. A control signal is sent back to the source
to control the delivery of data bursts from the computer. This arrangement avoids the use of the
computer’s inaccurate and jittery clock.

A word about music playing software
There are countless programs that can play music on Windows
and Apple Mac PCs. 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 at the original sample rate, while iTunes rate converts data as
necessary to the output sample rate set in the OSX Audio MIDI 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.
We suggest that you use a premium music streaming program, such as JRiver Media Center (Windows
or Mac) or Audirvana (Mac), rather than relying on the software bundled with the operating system.
