Sound Devices Microphone Interface for USB-equipped Macintosh® OS, Windows (Windows 7/ Windows Vista) and Linux computers

Sound Devices’ USBPre 2 is high-resolution, portable hardware interface for Mac- and Windows-based digital audio. The USBPre 2 interfaces professional microphones, line-level sources, consumer audio electronics, and S/ PDIF digital sources with Mac OS and Windows computers via USB. Its discrete-transistor microphone preamps with 24-bit converters and sampling rates up to 192 kHz provide the highest performance in a portable interface. Peak limiters, high-pass filters, and a 15 dB pad add overload protection.

All analog-to-digital and digital-to-analog conversion is done outside of the computer, in the USBPre 2, for superior audio performance.
USBPre 2 is a class-compliant audio device for plug-and-play connection to computers running Mac OS, Windows, and Linux. The USBPre 2 can be used in Stand-Alone mode as a portable microphone preamplifier and analog-to-digital converter.
Powered by the USB port of 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 2 allow no-compromise audio I/O everywhere.
