Description
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,
