OPERATION
USB input
For the USB input, the LED will flash in absence of digital input signal. When a signal is present, the LED will
light continuously.
Computer setup for input USB input
A good quality USB A to B cable is required to connect the unit to the computer.
Plug the B (square) end into the socket in the back of the M6PRE
Plug the A (rectangle) end into a free USB socket on the computer.
The computer should detect the new hardware and install a generic driver automatically (No setup or driver
disk required).
CD, MP3, WAV files played on any software should now play through the M6PRE. This device has been
designed to work with PC Windows 98, ME, 2000, XP as well as Apple Macintosh OS X.
Please note:
This device is a high speed serial data processor, and by its nature, requires a very high volume of USB
bandwidth. It will benefit greatly from being the only device connected on its USB ‘bus’. Sharing the same bus
with other devices may cause unwanted artefacts such as dropouts or temporary loss of signal. This especially
includes the use of the M6PRE on a USB hub/splitter alongside other USB components
