SOUND DEVICES, LLC
The USBPre relies on the USB port of the Mac for
its interface to the computer. The USBPre will not
function without a USB equipped Mac.
The requirements below outline the minimum con-
figurations for Windows computer systems with
USBPre hardware. Software applications used with
the USBPre have their own requirements that may
be in addition to the requirements of the USBPre.
Consult your software’s documentation.
Operating Systems:
Mac OS 9.0.4 and greater, OS X beta version
available on the web
Processor:
G3/266 or better, native USB port
RAM:
64 MB (128 MB with most software) physical
RAM with virtual memory turned off

66 MHz, 100 MHz recommended

for recommended for multi-track recording

For PowerBook and iBook users:
For proper operation of the USBPre, turn
off all power management when using the
USBPre for audio recording. Power manage-
ment reduces processor speed, system bus
speed, spins down hard disks, shuts down
displays, or a combination of the above to
reduce current consumption and extend bat-
tery run time. The change in state from active
to power-saving mode can disrupt data on the
USB bus and cause unintended dropouts.
Note: Sound Devices cannot guarantee that a
given computer can be used satisfactorily with
the USBPre based exclusively on the fact that
it meets the above requirements.
