Sound Devices' USBPre® 2 is a high-resolution, portable hardware interface for Mac- and Windows-based digital audio. The USBPre 2 is the industry's highest performance and most flexible portable interface, connecting professional microphones, line-level sources, consumer audio electronics, and S/PDIF digital sources with Mac OS and Windows computers via USB.

USBPre 2 includes two discrete-transistor microphone preamps with 24-bit converters and sampling rates up to 192 kHz. These preamplifiers provide the highest performance in any portable interface. Their topology is shared with Sound Devices' award-winning 744T Digital Audio Recorder. Peak limiters, high-pass filters, and a 15 dB pad provide overload protection. All analog-to-digital and digital-to-analog conversion is performed by the USBPre 2 for superior audio performance.

USBPre 2 allows for simple plug-and-play connection to computers running Mac OS, Windows, and Linux. There are no drivers to install for the USBPre 2 and there are no software-only features. All additional controls and settings are available on back panel DIP switches. The USB port also provides power to the unit, both when connected as an audio interface and when used in Stand-Alone operation.

Sound Devices USBPre 2 Features

  • Extended bandwidth
  • Low-noise microphone preamplifiers with 48 V phantom, limiters, high-pass filters, and 15 dB pad
