What We Think

What's Included

This little unit packs an unbelievable feature list and the legendary Sound Devices audio-quality and professional reliability, making it an ideal front end for any recording situation or home studio where two channels of very serious audio is demanded. The USB Pre 2 requires nothing more than a USB cable for power and interfacing with any DAW, making it an incredibly simple and portable solution. This remarkable little 2-channel device contains 2 clean Sound Devices mic preamps, absolutely outstanding AD/DA conversion, and a high-quality USB computer interface. It has truly impressive sound quality, considering its remarkably low price-point. It offers full resolution recording of up to 192k, 24 bit, and flat frequency response from 10hz to 40khz. The extended frequency range and low noise associated with its converters and mic preamps are the same as in Sound Devices’ award-winning 7-series products.


The A/D

The A/D is clear and clean, making superb recordings whether they are for live 2 channel recordings or for use in the studio when doing multiple overdubs on multi-track projects. The DA can be a great compliment to any computer-audio setup where high quality monitoring is essential, or when you just want to enhance your iTunes collection for audiophile sound quality.



Multitracking is also easily possible with the USB Pre 2 by stacking tracks. The USB Pre has zero-latency monitoring allowing the user to monitor source audio, computer audio, or a combination of the two. Record a guitarist and overdub the singer, building up multiple guitar parts and vocal harmonies with one little box. Alternatively, build a full band production 2 channels at a time trusting that your pres and converters are doing an excellent job translating the material.



The USB Pre 2 can make a great front end or back end to Pro Tools, as seen here. It can also be used with the program of your choice, including Sonar, Cubase, and Garageband.

The Sound Devices USB Pre 2 is the perfect device for monitoring any work that requires serious high-quality audio. It can be used with serious audio and video editing applications, for mixing on the road, or even for mastering CD’s.

It has a multitude of output connectivity, including balanced mic- or line-level on XLR, unbalanced consumer line-level on RCA, S/PDIF coaxial (RCA) and optical (Toslink).



The USBPre 2 has a wide range of interfacing possibilities. Use it to interface with your favorite external DI for recording guitars or keyboards, as an external mic preamp to provide a colored alternative to the clean sounding preamps in the box, to interface with an alternative digital device, be it an AD or DA converter, CD-burner, digital effect, or for lossless transfers of digital audio in and out of your computer to another digital device.

In standalone mode, you can use the USB Pre without a computer. The USB Pre 2’s powerful connectivity makes it possible to connect digitally to many devices, such as a CD-burner or an Alesis hard disk recorder for computer-less location recording. Record with the Sound Devices USB Pre2 in stand-alone mode by connecting directly to such digital devices, and immediately benefit from the Pre’s far superior mic preamps and converters, in and out. The output even has its own level control.

Other exciting possibilities with the USB Pre 2 include connectivity to Apple’s iPad as an input or output device. With the USB Pre 2, the iPad can be turned into a high resolution portable recording device. All you have to do is add a simple powered USB hub and you will be able to utilize all the great recording and playback quality of the USB Pre2 with your iPad.

Manufacturer's Description from Sound Devices

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 performing 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.

Precision Microphone Preamplifiers:

InputsUSBPre 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 add overload protection. All analog-to-digital and digital-to-analog conversion is performed by the USBPre 2 for superior audio performance.

Computer Connectivity:
The USBPre 2 is a class-compliant audio device. This 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.

Output Connectivity Flexibility:
To interconnect with sound systems big and small, the USBPre 2 includes numerous output connection types, including balanced mic- or line-level on XLR, unbalanced consumer line-level on RCA, S/PDIF coaxial (RCA) and optical (Toslink). The outputs have their own, dedicated front-panel level control. Use the balanced line-level signals to connect to powered loudspeakers. Use the optical S/PDIF to connect to hi-fi systems. Use the coaxial S/PDIF output in Stand-Alone mode for a portable microphone preamplifer with digital output for any production application.

Informative Metering:

Accurate signal level metering is essential for any sound engineer. The USBPre 2 includes a 23-segment, multicolor LED meter for precise level indication. The meter is switchable between input signal metering and output signal metering. The meter indicates both VU and peak (PPM) ballistics.

Stand-Alone Operation
The USBPre 2 can be used in Stand-Alone mode where it operates as a high-quality, portable microphone preamplifier and analog-to-digital converter. Digital signals connected to the USBPre 2 are converted to analog and available at the headphone, XLR, and RCA outputs. Stand-Alone operation requires the unit to be connected to a USB power source. Stand-Alone mode is a great option when an additional microphone preamplifer, A-D converter, or D-A converter is required.

Field-Tested Reliability

Like all of Sound Devices products, the USBPre 2 is designed to stand up to the most demanding environments. Its extruded aluminum chassis and aluminum panels, machined knobs, metal connectors, and laser-etched nomenclature are designed to hold up to years of abuse.

Class Compliant Drivers
As a class-compliant audio device, the USBPre 2 is limited to a maximum data rate of 24-bit, 48 kHz in Windows, Linux, and Mac OS versions 10.4 to 10.5.7. Mac OS 10.5.8 and higher support the audio class 2.0 device and can address the USBPre 2 up to 24-bit, 192 kHz.
