Sound Devices MixPre-3 II Multitrack Recorder and USB Audio Interface
Pocket-sized and built for the field, the Sound Devices MixPre-3 II is a five-track, 32-bit float recorder and USB audio interface with three Kashmir mic preamps.
It records to an SD card at up to 192 kHz, backs up to a USB thumb drive, and streams 5 in and 2 out over USB-C. The optional +2 Plugin turns it into a five-channel, seven-track recorder.
Recording
The three Kashmir preamps have adjustable limiters, and a built-in 3 × 2 mixer sets each ISO’s gain, pan, low-cut, and phase. Choose 16-bit, 24-bit, or 32-bit float at sample rates from 44.1 to 192 kHz. A 10-second pre-roll buffer catches the start of a take.
Timecode and Sync
An internal LTC timecode generator feeds the camera through the stereo output, timecode comes in on Aux In or HDMI, and HDMI can start and stop recording from a camera.
Power and Control
It runs on four AA batteries in the included MX-4AA sled, on Sony L-mount batteries with the optional MX-LMount sled, or on the included MX-PSU supply. USB-A accepts control surfaces, keyboards, and thumb drives.
Plugins
Optional plugins add NoiseAssist noise suppression, MixAssist automixing, the Musician mode for songwriting, and Ambisonics recording.
