STEP 4 – Using the USB1 interface with a computer
If you do not want to use a computer, you can miss out this step.
Compatibility
The
USB1
interface can be connected to Windows™ 8, Windows™ 7, Windows™ Vista (SP2 or later),
Windows™ XP (SP3) PCs, Mac™ OSX (10.5.4 or later) systems or a sound server, running software
to stream PCM data.
The interface should work with Linux Ubuntu servers and computers fitted with USB 2.0 interfaces that
natively support USB Audio Class 1 or Class 2 operation, but this has not been extensively tested.
Setting the USB Audio Class
There are two USB Audio classes, one of which must be set during system set-up. The Upsampler is
shipped set to USB Audio Class 2.
USB Audio Class 1: The interface operates without a special driver at up to 96kS/s.
To select Class 1, open the menu, navigate to the
Settings > USB Class
menu page. The
button sequence is:

and then use the
Menu
button to
select the
Class 1
icon.
USB Audio Class 2: The interface operates at up to 384kS/s (including DSD/64 over PCM).
For Mac OSX, version 10.6.3 or later is required.
For Windows, the
dCS
USB Class 2 Driver 2014 must be installed onto the computer before
use (see below).
To select Class 2, open the menu, navigate to the
Settings > USB Class
menu page. The
