 Description

USBPre 2 Portable High-Resolution Audio Interface
Sound Devices USBPre 2 is a high-resolution, portable hardware interface for
Mac- and Windows-based digital audio.

Features
• Extended bandwidth, low-noise microphone preamplifiers with 48 V phantom,
limiters, high-pass filters, and 15 dB pad.
• Dynamic range greater than 114 dB (in 24-bit operation).
• Flat 10 Hz to 40 kHz (@96 kHz SR) audio bandwidth with very low distortion
characteristics.
• Each input individually selectable between microphone, line, and aux level
signals (both channels selected simultaneously for S/PDIF connections).
• Precision, 23-segment, multicolor LED peak/VU meter, selectable between input
and output sources.
• High-output headphone amplifier can drive a wide range of headphones.
• Balanced outputs on XLR connectors with dedicated level control can be used
to drive line- or mic-level inputs.
• Mix control enables zero-delay monitoring of source audio, computer audio, or a
mix of both source and computer audio for multitrack recording or computer
telephony.
• Phono (RCA) jacks connect Aux Output to external loudspeakers or
preamplifiers.
• Bus powering via USB for convenient, single-cable connection to the computer.
• In Stand-Alone mode the USBPre 2 operates as a microphone preamplifier and
analog-to-digital converter.
• Hardware loop-through for test & measurement to send computer audio directly
back to an input.
• High-strength extruded aluminum chassis.
• Mac® OS X 10.4+, Windows®XP/Vista/7, and Linux
