32-Bit Float Capture for Fast-Paced Production

The MixPre-6 II is designed for situations where wide dynamic range and dependable recording flexibility are critical. Its 32-bit float recording mode helps users capture difficult sound sources with greater confidence, which is especially valuable for documentary work, interviews, unscripted production, and location recording where sound levels can change without warning.

Kashmir Preamps for Clean Professional Audio

Like other MixPre II recorders, this model uses Sound Devices class-A Kashmir microphone preamps for detailed, low-noise capture. With up to 76 dB of gain on mic inputs and support for 48 V phantom power, it is well suited to shotgun microphones, lavaliers, studio microphones, and professional field recording setups.

Six Inputs with Flexible Connection Options

The recorder is equipped with four XLR-1/4" combo mic/line inputs plus a 3.5 mm auxiliary input for additional sources. This makes the MixPre-6 II suitable for multi-mic interviews, compact production sound rigs, music capture, and flexible hybrid workflows that combine pro microphones with auxiliary feeds.

USB Audio Interface and USB Input Operation

When connected to a Mac or Windows computer, the MixPre-6 II works as an 8-input / 4-output USB audio interface for recording software. It can stream at sample rates up to 96 kHz, and on supported Mac systems it can send a complete 32-bit float audio signal over USB. It also supports up to four tracks of USB audio input, allowing users to record host-device feeds or backing tracks directly into the recorder.

Timecode Tools for Video Workflows

For filmmaking and production sync, the MixPre-6 II features an internal timecode generator along with dedicated 3.5 mm SMPTE timecode input and output connections. Micro-HDMI timecode input is also supported, helping the recorder integrate smoothly into camera-based and multi-device production environments.

Customizable Processing and On-the-Fly Control

The recorder provides adjustable analog limiters along with low-cut filtering, polarity inversion, delay, and pan controls. These tools help users optimize their setup for dialogue, ambience, effects, and general field recording without requiring a larger external mixer.

Bluetooth Control and Backup Workflows

Built-in Bluetooth allows remote operation through the Wingman app, which provides access to transport controls, high-resolution meters, and current timecode information. The ability to auto-copy recorded files from SD card to USB thumb drives also helps speed up backup and handoff in the field.

Ambisonics Support for VR and Immersive Audio

For VR, immersive sound, and game-audio applications, the MixPre-6 II supports optional Ambisonics functionality via a separately available plug-in. This adds support for simultaneous multiformat recording, real-time binaural or stereo monitoring, and A- to B-Format conversion for creators working in spatial audio production.

Expandable Platform with Optional Plug-Ins

The MixPre-6 II supports optional plug-ins that can expand its workflow capabilities. Firmware 9.0 adds support for audio and timecode output on the stereo 3.5 mm connector and supports two instances of the optional NoiseAssist plug-in, which can help suppress background noise during on-location recording.

Portable Design for Bag, Camera, or Tripod Use

Rugged, lightweight, and compact, the MixPre-6 II is designed for genuine field mobility. It can be carried in a bag or mounted to a tripod or camera setup, making it a practical choice for independent filmmakers, production sound mixers, field recordists, and immersive audio creators who need a portable but highly capable recorder.
