USB Input Operation with a Computer
The MA8000 USB-D/A Input provides the capability
to playback music from a computer, when the com-
puter is connected to the rear panel USB D/A connec-
tor. The MA8000 USB Input is compatible with both
PC Computers using Microsoft
®
Windows
®
(XP with
Service Pack 3, Vista with Service Pack 1 and Win-
dows 7) and the Apple
®
Macintosh
®
Computers using
OS-10.6 with the latest update.
When using a PC Computer with Windows, a spe-
cial McIntosh USB Audio Software Driver A needs to
be installed on the PC Computer. The driver needs to
be installed before connecting the MA8000 USB Input
to an USB Port on the computer.
Note: If an Apple Macintosh computer is used with the
MA8000, no additional driver is required.
