Sound Devices-USB Pre2 – Microphone interface

• Extended bandwidth, low-noise microphone preamplifiers with 48 V phantom, limiters, high-pass filters, and 15 dB pad.
• Dynamic range greater than 114 dB (in 24-bit operation).
• Flat 10 Hz to 40 kHz (@96 kHz SR) audio bandwidth with very low distortion characteristics.
• Each input individually selectable between microphone, line, and aux level signals (both channels selected simultaneously for S/PDIF connections).
• Precision, 23-segment, multicolor LED peak/VU meter, selectable between input and output sources.
• High-output headphone amplifier can drive a wide range of headphones.
• Balanced outputs on XLR connectors with dedicated level control can be used to drive line- or mic-level inputs.
• Mix control enables zero-delay monitoring of source audio, computer audio, or a mix of both source and computer audio for multitrack recording or computer telephon

• Phono (RCA) jacks connect Aux Output to external loudspeakers or preamplifiers.
• Bus powering via USB for convenient, single-cable connection to the computer.
• In Stand-Alone mode the USBPre 2 operates as a microphone preamplifier and analog-to-digital converter.
• Hardware loop-through for test and measurement to send computer audio directly back to an input.
• High-strength extruded aluminum chassis.
• Mac® OS X 10.4+, Windows®XP/Vista/7, and Linux, class-compliant audio device.
• Additional features controlled by hardware DIP switches on the back panel; no software-only features and no control panel.

he U46XL is a powerful multi-purpose 4-in 6-out multi-channel audio interface designed for various recording applications at home or on the road. The U46XL is the successor of to ESI Audio's famous U46DJ interface.

As its predecessor, it provides 2 stereo line inputs, a microphone input with +48V phantom power and a headphone output. A main difference is the improved analog circuitry improving the audio quality as well as the professional microphone preamplifier with XLR input. This makes the U46XL the perfect solution to record signals from dynamic or condenser microphones on the road or in your studio.

The unit also features an instrument input (Hi-Z), typically to connect a guitar directly to it. Two totally separate stereo line input on the backside provide 4 simultaneously usable input channels at one time. There are also 6 independent individual outputs on the backside, perfect for multi-channel playback applications like to provide individual outputs for software synthesizers, to provide independent playback channels for DJ software or to provide surround playback capability via a 5.1 setup. A separate mix output with professional TRS outputs could be used to connect U46XL to professional stereo studio monitors.

A cool feature is the DirectWIRE support in the driver, allowing you to record signals from one application to another internally. U46XL works with this driver based on our EWDM technology under Windows XP and Windows Vista/7, however U46XL is also Mac OS X compatible.

U46XL ships with Cubase LE 4 from Steinberg for Mac and PC to start recording on a professional level right out of the box.
