About Sound Devices USBPre 2

Let the Sound Devices USBPre 2 Microphone Interface revolutionize your computer audio experience. This high-resolution, compact, and portable hardware interface is compatible with both Mac and Windows operating systems, making it a versatile tool for all your digital audio needs.

Designed to connect professional microphones, line-level sources, consumer audio electronics, and S/PDIF digital sources, the USBPre 2 stands out as the industry's top-performing and most adaptable portable interface. It features two discrete-transistor microphone preamps equipped with 24-bit converters and sampling rates that reach up to 192 kHz, ensuring the highest quality audio performance in any portable interface.

The USBPre 2's preamplifiers share a topology with Sound Devices' award-winning 744T Digital Audio Recorder. With peak limiters, high-pass filters, and a 15 dB pad, this device offers superior overload protection. All analog-to-digital and digital-to-analog conversions are performed by the USBPre 2, guaranteeing superior audio performance.

The USBPre 2 is a class-compliant audio device, allowing for effortless plug-and-play connection to computers running Mac OS, Windows, and Linux. No drivers are required for installation, and all additional controls and settings are conveniently located on the back panel DIP switches. The USB port also powers the unit, whether connected as an audio interface or used in Stand-Alone operation.

For maximum output connectivity flexibility, the USBPre 2 includes a variety of output connection types, such as balanced mic- or line-level on XLR, unbalanced consumer line-level on RCA, S/PDIF coaxial (RCA), and optical (Toslink). Each output has its own dedicated front-panel level control, allowing you to connect to powered loudspeakers, hi-fi systems, or use the coaxial S/PDIF output in Stand-Alone mode for a portable microphone preamplifier with digital output.

The USBPre 2 also features a 23-segment, multicolor LED meter for precise level indication, switchable between input signal metering and playback signal metering. This device can also operate in Stand-Alone mode, functioning as a high-quality, portable microphone preamplifier and analog-to-digital converter.

Like all Sound Devices products, the USBPre 2 is built to withstand the most demanding environments. Its robust construction features an extruded aluminum chassis and panels, machined knobs, metal connectors, and laser-etched nomenclature, ensuring it can endure years of use.

Experience the superior audio performance and flexibility of the Sound Devices USBPre 2 Microphone Interface for Computer Audio, a tool designed to meet the needs of professionals and audio enthusiasts alike.
