The groundbreaking new MixPre-3 is a lightweight, high-resolution audio recorder with integrated USB audio streaming that offers world-class sound quality combined with extreme durability – perfect for musicians, sound designers, podcasters, videographers, YouTubers and field recordists.
Sublime Audio Quality
The MixPre-3 features Sound Devices’ new Kashmir™ microphone preamps. These high-performance, ultra-low-noise, discrete, Class-A mic preamps were hand-crafted by Sound Devices. The Kashmir mic preamps feature a -130dBV noise floor, analog limiters, and new 32-bit A-to-D converters to ensure the highest quality audio recordings that far surpass those of other recorders using simple off-the-shelf IC-based mic preamps.
