The USBPre 2 from Sound Devices is a high-resolution, portable interface that connects professional microphones, line-level sources, consumer audio electronics and S/PDIF digital sources with Mac OS X and Windows computers via USB. The unit includes two discrete-transistor microphone preamps with 24-bit converters and sampling rates up to 192kHz. The preamp topology is shared with the company's premier 744T digital audio recorder and includes peak limiters, high-pass filters, and a 15dB pad for overload protection.

The interface is a class-compliant audio device, allowing for simple plug-and-play connection to computers running Mac OS X, Windows and Linux operating systems. There are no drivers to install and no software-only features, with all additional controls and settings 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. All analog-to-digital and digital-to-analog conversion is performed by the USBPre 2.

When used in stand-alone mode, the unit operates as a high-quality, portable microphone preamplifier and analog-to-digital converter. Incoming digital signals are converted to analog and available at the headphone, XLR and RCA outputs. This mode is a great option when an additional microphone preamplifer, A-D converter, or D-A converter is required.

The unit includes numerous output connection types, including balanced microphone 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. The USBPre 2 includes an accurate 23-segment, multi-color LED meter for precise level indication. The meter is switchable between input and output signal metering. The meter indicates both VU and peak (PPM) ballistics.

The interface is designed to stand up to the most demanding environments. Its extruded aluminum chassis and panels, machined knobs, metal connectors, and laser-etched nomenclature are designed to hold up to years of abuse.

              Particularly interested in the standalone mode.
              I use it to provide first class preamps to consumer grade digital recorders with S/PDIF digital input.

                I wanted to use this to dj from my laptop. But to do that you need 4 channels of output not just 2 as on the USBPre 2. So I returned it. But I really wished I hadn't had to; it's DtoA output and AtoD inputs are amazing, it has more ins and outs than any other device I researched (plus 2 headphone jacks), and the build quality is easily the best I've ever seen. If you only need 2 channels of output, and you want to input mics or instruments, buy this, it's the best.

                Comments about Sound Devices USBPre 2 - Microphone Interface for Computer Audio:

                I am using the USBPre 2 as a phono preamp, ADC and DAC in my home sound system. This unit amplifies the signal from my low output MC cartridge (an Ortofon A90) and converts the amplified analog signal to 192K / 24 digital. This data stream is sent to my computer via USB. The computer handles storage and RIAA equalization using Pure Vinyl software. The USBPre 2 also handles conversion back to analog, which is sent to my conventional sound system (preamp, amplifier, speakers) for playback.

                I am simply amazed at the sound this unit produces. Its performance is actually better than what I can achieve by playing vinyl directly through a conventional high quality phono preamp.

                When used as a DAC, I can not tell the difference between it and my tubed stand-alone DAC.

                I am making these comments based on listening through a high end sound system (preamp, tube mono bloc power amps, and monitor speakers) that is very capable of resolving subtle differences in source components. So, I feel pretty comfortable in recommending this unit.

                Not much more I can say. since this is my first experience with computer audio. Others have compared this unit favorably to the highly regarded Lynx sound card, which is high praise indeed.

                  Easy to use right out of the box. I like flexible configuration options (via dip switches), stand-alone capability, and excellent metering. The built-in headphone amplifier makes monitoring very easy.

                  Worked flawlessly on a Windows XP 32-bit laptop, but I had some trouble with the class compliant drivers when connecting to a USB 3.0 port on a Windows 7 64-bit laptop. Installing the ASIO drivers for Windows 64-bit solved my issue and now everything is working well.

                    Comments about Sound Devices USBPre 2 - Microphone Interface for Computer Audio:

                    I'm a graduate student at North Carolina State University studying sociophonetics. So, I mainly use the USBPre 2 in conjunction with the Audix HT5-P headset microphone and my laptop computer to record interviews for my research. The USBPre works as a great preamp and analogue-to-digital converter. Most importantly it allows for high sampling rates and bit-depth and thus quite a bit of spectrographic detail - an important part of any sociophonetic analysis. One feature that makes it better than the previous model is the stand-alone mode which allows for interfacing with a portable recorder such as a Sony PCM-M10, and not just a computer. The quality of the recordings I am capable of capturing now that I've purchased the USBPre 2 is head and shoulders above any of the previous recordings I've done. As such any linguist looking for a preamp-A/D converter in one package should look no further than the USBPre 2.

                      Comments about Sound Devices USBPre 2 - Microphone Interface for Computer Audio:

                      My USB Pre 2 came and, like Sound Devices recorders, it is another finely engineered piece. I run it on a USB battery in standalone mode with small digital recorders, a MicroTrack II, a Tascam HD-P2 and a DR-680. It's a perfect complement to SD744T recorders which have two preamps but 4 channels. This little box will make top notch digital recordings with portable digital recorders or a laptop computer, and what you get for the price is incredible. The mic preamps, converters, headphone amp and analog outputs all sound stellar.

                      P.S. The little mixer knob lets you adjust precisely how much recorded vs playback sound you want which is ideal for layered multitrack recordings. Nothing in this price can touch it.

                      I'm excited that truly pro-level preamps now fit inside a portable computer interface, and smaller budgets too.

                        Sound Devices has hit a home run with their new USB Pre 2 external sound card. It's really well thought out with just the right inputs, outputs, monitoring functions, 23 segment multi-color LED VU/Peak metering, etc. They use pro quality components like Neutrik connectors, metal case and knobs, etc. I've done some test recordings at 24bit/192kHz with my MKH416 using a 11.6" screen Acer Netbook running Vista and Sound Forge Studio 10. The most striking thing is almost NO discernable hiss on the mike preamps. Sound Design has put exactly the same mike preamp technology in this [$] jewel that they use in their high end 700 series digital location recorders. So for that price and a netbook running entry level professional recording software like Sound Forge Studio (SFS10 is the first version that will support 24/192 recording) you get a Hollywood quality recording system for about 1/2 of what it would normally cost. In my opinion it's a much more versatile system than a stand-alone recorder since you're using a computer for software and capture.Now if they would just include Time Code. ;-)
