USBPre® 2 Microphone Interface for Computer Audio
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 the 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.
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-levels on XLR, unbalanced consumer line-levels 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.
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.
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 are 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.
Like all 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.
