OPERATION
Selecting the USB Mode
The
MODE
pushbutton, located next to the USB port, is used to select between
the following two USB modes:
•
Class 1 Mode (Cyan USB Port LED)
This is the default BLU-USB mode. This mode
is USB Class 1 compliant and doesn't require
any additional drivers be installed to use
the BLU-USB with either a Windows or Mac
computer.
This mode is limited to 2 x 2 audio channels
(1 stereo pair in and out) and only supports a
BLU link bus sample rate of 48kHz.
•
Class 2 Mode (Magenta USB Port LED)
This mode is USB Class 2 compliant and
requires an additional driver be installed to
use the BLU-USB with a Windows computer.
NOTE:
Mac computers do not require any
additional drivers and will use the Core Audio
driver installed with OS X.
This mode provides 8 x 8 audio channels (4
stereo pairs in and out) and supports BLU link
bus sample rates of either 48kHz or 96kHz.
To switch between modes:
1.
Use a small, pointed object — such as the tip of a paperclip — and press
and hold the recessed
MODE
pushbutton until the USB port LED changes
color (~10 seconds). See
if the BLU-USB
does not properly change modes as shown above.
NOTE:
The selected mode will be retained after power cycling the BLU-USB.
