Kashmir Mic Mic Preamps

The MixPre-3 features Sound Devices’ groundbreaking Kashmir™ microphone preamps. These high-performance, ultra-low-noise, discrete, Class-A mic preamps  were custom-engineered by Sound Devices. The Kashmir mic preamps feature a -130dBV noise floor, analog limiters, and new 32-bit A-to-D converters, and ensure the highest quality audio recordings that far surpass those of other recorders using  simple off-the-shelf IC-based mic preamps. 

Powerful USB Audio Streaming

Record while streaming USB audio at the same time. The versatile MixPre-3 makes an excellent USB audio interface, with the unique ability to record audio to an SD card while simultaneously streaming multiple channels of audio via USB. Handy for interviews, podcasts, or simply as a backup recorder to your computer, the MixPre-3 can be used to record Skype or Facetime interviews, and record audio for podcasts or video blogs.

Easy to Use

Pocket-sized, unintimidating design. The MixPre-3 is the first of its kind to offer a sunlight-readable, color, IPS LCD with touch-screen technology for easy navigation. With built-in Bluetooth Smart® technology, the MixPre recorders also provide full remote control and metering via mobile devices, using Sound Devices free Wingman app.

For the ultimate in portability and convenience, the MixPre-3 offers multiple powering options. From AA cells  to Li-Ion batteries for all day recording, to powering from a computer or AC wall outlet, the MixPre Series are ready when you are.
