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.
