Computer System Requirements

The requirements below outline the minimum confi gurations for systems using the USBPre 2. Soft-
ware applications used with the USBPre 2 have their own requirements that may be in addition to
the requirements of the USBPre 2. Consult your software's documentation.
Operating Systems
Windows XP (SP3), Windows Vista, Windows 7 (both 32 and 64 bit)
Macintosh OS 10.4 or greater
Linux Kernel 2.6.0 or greater (Requires standard ALSA snd-usb-audio module)
USB Audio Device Class
Windows, Linux and Mac OS versions below 10.5.8 utilize USB Audio Device Class 1.0 drivers
that will limit the USBPre 2 to sampling rates of 48 kHz and lower.
Mac OS 10.5.8 and greater utilizes USB Audio Device Class 2.0 drivers that will allow the full
range of sample rates that the USBPre 2 is capable of.
USB Connection
Full USB 1.1 or 2.0 compliance
For Notebook Computer users:
For proper operation of the USBPre, turn off all power management when using the USBPre for audio
recording. Power management 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 battery run
time. The change in state from active to power-saving mode can disrupt data on the USB bus and cause
unintended dropouts.
Sound Devices cannot guarantee that a given computer can be used satisfactorily with the USBPre 2
based exclusively on the fact that it meets the above requirements.
