Sound Devices USBPre

Sound Devices USBPre is a complete, portable hardware interface for PC-based digital recording. Designed for USB-equipped Macintosh® OS 9 and Windows® computers (98SE, 2000, and ME) , USBPre quickly and easily interfaces microphones, line level sources, musical instruments, and consumer audio electronics with personal computers. Its high quality, 24-bit audio inputs offer the most direct signal path into the computer. All analog-to-digital and digital-to-analog conversion is done outside of the computer, in the USBPre, for superior audio performance.

USBPre has the flexibility to work with most Windows and Mac recording and streaming software. Powered by the USB port from either notebook or desktop computers, no additional power source is required - the computer provides all power needed for operation. The durable construction and compact size of the USBPre allow no-compromise digital recording everywhere.
