5Select the USB Mode
The following modes are available:
• Class 1 Mode (Cyan USB Port LED)
Provides 2 x 2 channel I/O and is limited to a 48kHz BLU link bus
(96kHz is not supported). Doesn’t require any drivers be installed to
use with Windows or Mac computers.
• Class 2 Mode (Magenta USB Port LED)
Provides 8 x 8 channel I/O and support for a 48kHz or 96kHz BLU link
bus. This mode requires the Windows driver be installed for Windows
computers. Mac computers don’t require any additional drivers.
To change the mode, 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).
6Route Computer Audio
In the computer or software application, configure the BLU-USB as the
input and/or output device. Make sure to configure the sample rate and
bit rate to match the BLU link bus (48kHz/24-bit or 96kHz/24-bit). See the
BLU-USB Installation Guide for more information.
