USBPre Microphone Interface for Computer Audio
Two-Channel Microphone Interface for Computer Audio
Sound Devices USBPre 1.5 is a complete, portable hardware interface for computer-based digital recording. Designed for USB-equipped Macintosh® OS 9, OS X, and Windows (98SE®, ME, 2000®, XP) computers, USBPre quickly and easily interfaces studio 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 conversion is done outside of the computer, in the USBPre, for superior audio performance. S/PDIF coaxial I/O enables direct digital transfers into and out of the computer.
USBPre has the flexibility to work with most Windows and Mac recording, streaming, and measurement software. Powered solely 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.
IMPORTANT NOTICE: The USBPre does not operate in 64-bit operating systems. This includes Windows XP-64, Windows Vista-64, Windows 7-64, and any release of Mac OS X 10.5 ("Leopard") or later.
