If you record field audio, sound effects, podcasts, voice-overs, music, audio for film, or are just starting your audio journey, the MixPre-3 II is for you! With three crystal-clear, ultra low-noise Kashmir preamps, you can record multiple actors, multiple podcasters, or audio for small productions with superior quality – all the way up to a 32-bit float bit depth and a 192 kHz sample rate. This newest generation of Sound Devices’ award-winning MixPre Series has been redesigned for increased performance and an astounding 142 dB of dynamic range.
Your MixPre-3 II is highly customizable to your needs. Record internally to a compatible SD card on set or stream your podcast over USB to your computer at home.

Adjust limiters, bit depth, sample rates, gain, pan, low-cut, phase inversion and phantom power to your liking. Trigger your camera with the internal timecode generator, or feed timecode in via HDMI or Aux In. The choice is yours!
