Two Channels to Go!

Borrowing the same award-winning microphone preamplifiers found on their 744T digital portable interface, the Sound Devices USBPre 2 provides one of the highest quality portable interfaces available for both Mac and Windows computers. The USBPre 2 is equipped with a pair of fully discrete, transistor-based XLR inputs and impressively lucid 24-bit converters that are capable of up to 192kHz sample rates. Additional inputs for line-level sources and consumer audio electronics, as well as S/PDIF optical Toslink digital devices are also available. A 23-segment, multicolor LED meter provides you with the essential feedback you need to keep an eye on your levels, and are an invaluable asset when using the USBPre 2 as a standalone preamp and A-to-D converter.

  • Flat 10Hz to 40kHz (@96kHz SR) audio bandwidth with very low distortion

Meticulously Phenomenal

Nothing compares! I went through a slew of different mic preamps trying to get decent clean gain over the years (I'm super fond of the Sure SM7b and the RE 20 both of which are very low in output level). Everything stopped when I encountered the Sound Devices pre-amps. They have a lot of gain and are not only clean but also precise. There is no added coloration. Their equipment is built to beyond-military grade standards and I have never had an issue with anything from them. I work in radio and have a budget of zero but these are worth every penny of the price.

Outstanding Customer Support

You probably won't have any issues with the new 2 but if you do the Sound Device tech support department is terrific! They're smart, helpful, and friendly. So what if they're Packer fans!

Just got mine from Sweetwater. Works beautifully with my MacBook Pro as an audio interface. No drivers needed to install. Clean preamps, much better them my M-Audio and Zoom stuff a used... Gives you total control and connectability. Small, handy but very well built peace of professional equipment. Love it!

USBPre 2

I don't get a lot of five star pieces of equipment but this gets it hands down. I purchased it to record with my iPad. AKG C24, iPad with Multitrack DAW, and USBPre2 equals a cool little setup. It works great to mix through with my HD rig and really fun to check mixes with. It is a really nice piece of professional audio equipment. I was not disappointed in the least.

USBPre 2

I just received this today and I have been very excited. Expectations have been met and then some. The clarity of this interface blows my old pci soundcard out of the water. I have been searching for years to replace my old gear and it finally paid off. Though this is a pricey unit, it is everybit quality defined. The dynamic range is incredible, paired with high quality XLR cables I can now listen to my music the way it was intended by the mixing engineer. Stereo separation is more defined and bass is more rich (although not colored). The process for updating firmware and ASIO driver were very easy. I look forward to years of enjoyment!

The Sound Devices USBPre 2 gives you the best quality from outside in and from bottom to top. I've had very high-end customers compare this unit to convertors four times the price! No hype, no problems.
