Sound Devices MixPre-6 II Overview

Bundled together by B&H for your convenience, the Sound Devices MixPre-6 II Audio Recorder/Mixer Kit provides the aforementioned recorder/interface as well as a Strut STR-MP6 carry case for transporting the MixPre-6 II in the field.

The recorder sports several upgrades over the previous model, including 32-bit recording and 32-bit USB streaming to ensure audio that's virtually free of distortion as well as a built-in timecode generator. The relatively compact recorder also doubles as a USB interface, giving you Kashmir microphone preamplifiers, timecode compatibility, advanced and basic navigation modes, and a built-in 1/4"-20 mount for videographers. 

The Strut STR-MP6, on the other hand, offers a removable rain top, clear vinyl window, padded main compartment, and room for four G3 (or similar) receivers. The case also includes belt loop and harness attachment points as well as an HAR-2 audio harness and support for sleds that house four or eight AA batteries.

Sound Devices MixPre-6 II 6-Channel / 8-Track Multitrack 32-Bit Field Recorder

For independent filmmakers, field recordists, and Ambisonic enthusiasts who need pristine audio capture of up to four microphones, the Sound Devices MixPre-6 II multitrack field recorder is an ideal tool. Record up to six tracks of external sources (four channels via XLR-1/4" combo jacks and two channels via a 3.5mm mini jack)—as well as a stereo mix—at sample rates and resolutions of up to 192 kHz / 32-bit, all while monitoring audio in headphones. If you choose to use the MixPre-6 II as your studio interface, you'll be able to achieve sample rates up to 96 kHz. 

The MixPre-6 II offers many upgrades over its predecessor. Chief among these features is the ability to record at 32-bit floating point to an internal SD card. The unit also functions as an audio interface capable of 32-bit floating point streaming over USB to a Mac computer. 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-6 II maintains accurate timecode for up to four hours.

All of this is available in a six-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-6 II will suit any intimate, field-based production.

Kashmir Preamps
Like the original unit, the MixPre-6 II offers class-A Kashmir mic preamps. All inputs are fully RF-filtered to keep interference out.
Audio Interface Functionality
When connected to a Mac or Windows computer, the MixPre-6 II can serve as an 8-input / 4-output USB audio interface for your favorite audio recording software. The unit will record six tracks in isolation and provide a stereo mix of all six channels to boot. It will operate at sample rates up to 96 kHz.

The unit can send a complete 32-bit float audio signal over USB when connected to a Mac computer running macOS Catalina (version 10.15 or later).

USB Audio Input
Stream up to four tracks into the unit over USB, using the MixPre-6 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.
A Cornucopia of Connections
For inputs, you'll find four XLR-1/4" combo jacks and a 3.5mm auxiliary input. Audio output connections are handled over 3.5mm jacks. 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, delay, 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-6 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.
Ambisonics Integration
Upon installation of the Ambisonics plug-in (available separately from the Sound Devices plug-in store), field recordists, game developers, and VR content creators will appreciate the support for simultaneous multiformat recording (AmbiX, FuMa, LR Stereo, and LR Binaural), real-time binaural/stereo monitoring, and A- to B-Format conversion.
Transport and Mounting Options
The MixPre-6 II is rugged, lightweight, and relatively compact, so you can throw it in a bag or mount it to a tripod or camera.

Sound Devices MixPre-6 II Reviews

Best user interface in its class

By Bruce
Rated 5 out of 5
Date: 2023-03-14

I own the Zoom H6 recorder and when looking to upgrade I first purchased the Zoom F-6 recorder. The specs for the Zoom F-6 looked great and I liked how one could attach NP-F batteries without needing a sled adapter. But when it came time to make the initial configuration changes I encountered a user interface like something from the 1980's. The Sound Devices has a truly intuitive interface with its color touch screen and overall configuration and settings layout and menu structure. I also liked being able to easily gang two of the pots so for stereo mics I only needed to adjust one dial to change the gain of both channels. The primary defects in terms of its design is having the SD card slot blocked by any sled that is attached and having the On/Off switch very difficult to access when a USB-C power cable is attached. On the plus side the USB-C port works well to power the MixPre for more than a dozen hours with a single power bank. The MixPre also has the copy to USB so a thumbdrive and collect the files from the USB-A port on the recorder.

Incredibly reliable, fantastic results

Best field recorder in this price range, and punches well above its weight in regards to sound quality, flexibility and build quality. Used this as my main recorder for a few features and tons of small jobs in between. Its very easy to use, the preamps are very quiet and have tons of headroom, even before you push 32bit files. Time code is rock solid and I've jammed this to an Ambient Nanolockit for 12 hours a day with no drift. OS is very easy to navigate and the Wingman App is great. 6 inputs is very flexible for small productions and the only real thing it's "missing" would be another stereo output, but again for the size and price it evens out. The battery life is a non-issue because there is no recorder with this much power that can reliably run off AAs; they're a backup. The upside is it runs off inexpensive USB battery banks so you can run this for 15 hours or so with a $50 battery. It's not a replacement for an 8 series, but it would make a great backup to that unit, and it's the clear winner compared to anything from Zoom/Tascam in the price range.

Incredible value for the money

This is the best value for a prosumer recorder out there. I am not sure that the 833, at five times the cost, is definitely a step up, but I am not actually certain that it delivers five times the value (the MixPre-6 is NOT a substitute for the 833, I'm just saying that if you're in the market for this, you're probably not in the market for that). The sound reproduction is incredibly good, the preamps deathly quiet, the construction solid and amazing, using excellent, high-end components (the XLR input plugs are an exception to this in that they are merely fine, not great) and the recording and mixing controls given are superb - not just superb for the price, but superb. Customer support - by email and phone - is a throwback to another era, one in which competent engineers answer the phone and expertly walk you through issues with a product they truly understand.

I use it with my Rode M5 match pair along with some vocal mics and create perfect workable files every time, without exceptions. Best piece of audio equipment for my growing video needs. I originally owned the premix 3 and was going to sell it once the premix 6 arrived, but the peace of mind of these devices swayed me to keep both.

Great quality sound, intuitive design, but one major issue

By alireza
Rated 2 out of 5
Date: 2022-01-20

So the sound quality is the best bar none. I have the F6 and this has a nicer, richer sound to it (by 10-20% or so) and the design is very intuitive but i ended up sending mine back. Why? My main issue was the battery sled and the power options it has. Alkaline batteries last about 15-20 minutes. Nimh rechargeables last about 50-60 minutes. in addition, the battery sled feels like an afterthought. I've seen nicer pieces of plastic at Toys r us. Unlike the F6, you can't just plug in a usb c phone charger has a special usb c charger. If you want to buy batteries that actually work, you're looking at another 200 bucks. And they've stopped making the mixpre 3.....forcing me to buy the 6 for an extra 220 dollars (360 more than the f6) All in all, i couldn't justify the slightly nicer sound and intuitive design for the battery flaws and the higher cost.

I'm constantly surprised by the quality of this machine. currently its my main recorder for podcasting and it lives as a backup mixer kit for my more pro kit. I'm mostly using it with shure mv-7 mics or a variety of zaxcom wireless and rode wireless go II's (yea, I know what you're thinking, big difference, all about knowing your gear's strength and weaknesses). AA's are worthless for this rig except for quick emergency, I use the sony np-f batteries and get a good half a day. my biggest complaint is the tolerance on the xlr release switches, some plugs can be kinda sticky. but this machine rips and I'm psyched to have it.

Do I need to add a mixer to this? If I do add a mixer, what do I gain?
Asked by: Phillip
No, a separate mixer is not required for use with the Sound Devices MixPre-6 II 6-Channel / 8-Track Multitrack 32-Bit Field Recorder. Whether you might want to use a separate mixer depends on the requirements for a specific application. For example, you could use a separate mixer if you need additional input channels to connect more than four microphones, instruments, or line level audio sources to record simultaneously.

Can you mount this on a tripod then mount a camera on top? What would be the weight limit?
Asked by: Angelo
Angelo, please do your research. The answer to your question lies within the product description. For the second answer, I wouldn’t mount a cinema camera that weighs 25lbs. For that you can mount on top of the camera. If your question is regarding your tripod, it also has a weight rating. Go to for more information and get familiar with the product. For further comments that are not readily available, folks like me will be happy to answer.

I have the original MixPre-6. I love it except for the USB-C port. The cable slips out of the port easily. This becomes very frustrating in live stream scenarios. Was this fixed? Does it 'stick' like a usb-c port in the phone, or is it still a bit loose? My current one is so loose that a small jostle will give me a low power warning.
Asked by: Sarah
Update! Sound Devices sent me a new cable and it works! THANK YOU!!! We've been using for church live-streaming weekly - getting the audio feed out of the soundboard and into the computer. Because of the device and stellar support, I've decided to purchase a second one (version II) so I can leave one at the church instead of hauling it back and forth.

Via USB, No. If your camera can send timecode over HDMI it will work. Set your camera timecode to be RECORD RUN and make sure it is being sent via the HDMI cable. Set your MixPre6 for timecode record trigger. I have done this with other cameras - it works very well.

I hope someone can help me think ahead about what I can do with the aux input on the MixPre-6.
