It is what you think it is, so I won't go into that, If you looking at it then you know. So, one gripe: The battery tray is finicky and plastic. It's the only cheap-ish aspect to this whole thing. But it's not really important. I won't be using batteries like that, I'll be powering it through the usb-c connector always. If you're going to be attaching it under a camera or other thing temporarily with the 1/4 20 then just slip that allen wrench in your pocket, that magnet is strong! 32bitfloat/192 with 128gbSony SD (not on their supported list but works for me!) gives me 9 hours!!

This is thing is good - reeaaalllly good. Once your ears taste the dead silence of these preamps, there ain't no going back. The small touch screen is working better than I expected. The on/off button placement and usability is not the greatest, but the sound fidelity from this unit makes up for any of the little problems. Way to go Sound Devices!

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 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. Power with your computer, wall power, or record in the middle of nowhere with AA or Sony L-mount batteries. 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!
Professionals love the flexibility of the MixPre Series. Don't need all those options? Basic mode has you covered.
Your MixPre-3 II is rugged, lightweight, and small, so you can throw it in a bag or mount it to a tripod or camera - or get situated on set with our Wingman App and one of our four supported USB control surfaces.
