Sound Devices USB Pre 2 Interface

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.

Precision Microphone Preamplifiers

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.

Computer Connectivity

USBPre 2 is a class-compliant audio device. This allows for simple plug-and-play connection to computers running Mac OS, Windows, and Linux (see note to the right on Class-Compliant Drivers). 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 playback 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.

A most useful unit. All metal construction no plastic bits to break off. It is ideal to chuck in a bag with a laptop and, being bus powered, no mains connection is required. However, it can be used stand alone without a computer with any USB power supply. It has inputs and outputs for every purpose likely to be encountered. The headphone amplifier is very powerful and great quality. It is simplicity itself to use and gives perfect results. An excellent piece of kit.
