Sound Devices MixPre-3 II 3-Channel / 5-Track Multitrack 32-Bit Field Recorder

For independent filmmakers, field recordists, and podcasters who need pristine audio capture of up to three microphones, the Sound Devices MixPre-3 II multitrack field recorder is an ideal tool. Record up to three tracks of external sources plus a stereo mix at up to 32-bit / 192 kHz while monitoring your audio headphones.

The MixPre-3 II offers many upgrades over its predecessor. Chief among these features is the ability to record at 32-bit floating point. This makes it nearly impossible for you to clip (distort) audio on the way in. Whether you're recording hot or making use of the unit's astounding 142 dB dynamic range, you'll only be handicapped by the quality of your microphone.

Other improvements include the ability to auto-copy recorded tracks to USB thumb drives, making file transfers a breeze. Lovers of sync will revel in a handy new feature: a full-fledged, built-in timecode generator, accurate to better than 0.2 ppm (0.5 frames in 24 hours). Even when powered off, the MixPre-3 II maintains accurate timecode for up to four hours.

All of this is available in a three-channel package that can be powered from wall chargers, computers, AA batteries, or Sony L-series batteries. Whether you use the device in an advanced or basic capacity, the MixPre-3 II will suit any intimate, field-based production.

Kashmir Preamps

Like the original unit, the MixPre-3 II offers class-A Kashmir mic preamps. All inputs are fully RF-filtered to keep interference out.

On-Board Mixing

Create a mix using the built-in 3x2 portable mixer.

Audio Interface Functionality

When connected to a Mac or Windows computer, the MixPre-3 II can serve as a 5-input / 2-output USB audio interface for your favorite audio recording software. The unit will record three tracks in isolation and provide a stereo mix of all three to boot.

USB Audio Input

Stream up to two tracks into the unit over USB, using the MixPre-3 II as a recorder from your host device. If you're a musician, you can utilize this feature to record a stereo mix from your host DAW as a backing track for further standalone recording.

Connections

For inputs, you'll find three XLR jacks. Audio output connections are handled over a 3.5mm jack. Timecode I/O is made possible via 3.5mm connections, though you also have the option of HDMI for inputting timecode.

Adjust on the Fly

Adjust the limiters, change the bit depth, shift panning and polarity in the stereo mix, and filter out extraneous bass rumble with low-cut filters. Whether you record to an SD card or to your computer over USB, the MixPre-3 II can be customized to your needs.

Built-In Timecode Generator & Bluetooth Control

Thanks to the device's timecode generator, you can even trigger recording from the camera. With built-in Bluetooth, you can control the unit over the Wingman app, available from Sound Devices. This app displays high-resolution meters, current timecode, transport buttons, and more.

Transport and Mounting Options

The MixPre-3 II is rugged, lightweight, and relatively compact, so you can throw it in a bag or mount it to a tripod or camera.
