Install the Windows® Driver (If Applicable)

If using a Windows computer, Class 1 (2 x 2) mode can be used without installing any drivers (this is the default mode).

To use Class 2 (8 x 8) mode, download and install the BLU-USB Windows driver from http://bssaudio.com/en-US/products/blu-usb#downloads. See step 5 for additional details on modes.

IMPORTANT!!!

If using Windows 7, the Windows KB3033929 update (released March 2015) MUST be installed to use the BLU-USB in Class 2 mode.

NOTE:

Mac computers do not require any additional drivers and will use the Core Audio driver installed with OS X.

Assign the Channel Banks

Use the DIP switches to assign on-ramp and off-ramp channel banks (see table). ON-RAMP = From computer to BLU link. OFF-RAMP = From BLU link to computer.

NOTE: Channels 1-256 are available when operating at a 48k Hz BLU link sample rate; channels 1-128 are available when operating at a 96k Hz BLU link sample rate.

Apply Power

Connect the included power supply and IEC power cable.

Make Connections

Select 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 48k Hz BLU link bus (96k Hz 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 48k Hz or 96k Hz 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).

Route 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 (48k Hz/24-bit or 96k Hz/24-bit). See the BLU-USB Installation Guide for more information.
