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.

I've used the recorder for a period of a month now, so far so good. The battery plate is okay but easily consumed. The sony battery mount looks too flimsy (and has been reported to be so) to consider and is definitely overpriced. The audio quality is fantastic (clean and quiet) and there are ways to easily set LPF and HPF options which really help with certain environments. I tried it as an audio interface with a mix-minus and that worked pretty well too. Wishlist: more robust battery options, 2 sd card slots, 32bit float recording physical quick switch, bluetooth control for midi interfaces (wireless sliders), 1/4 headphone jack, lastly.... a spring 1/4 screw that can be locked instead of this push up mess that is inaccessible once you use the bottom 1/4 mounting hole. Overall though, great product, depending on how well it does in the next few months, I may purchase the noise assist plugin.

Great high-headroom audio recorder

By Chad

I'm mainly an audio guy, so the ways of the video world are a little mysterious to me. I'm self-shooting videos for YouTube and I've gone through several different solutions for capturing audio to go along with my video over the years. All of those solutions resulted in having a separate track for each mono or stereo audio input, so imagine my confusion when the MixPre presented me with a single 6-channel WAV file as the recorded output. Thanks to the plethora of information available on the interwebs, I was able to learn how to work with this kind of file. As an audio guy, I'm familiar with the concept of a master bus and the tracks that feed into it, so I was able to navigate the options and setup well enough. I do wish that there was a way to use the knobs as gain control when not in basic mode. It seems strange to have to use a tiny spot on the touch screen to adjust the single most important control on a preamp rather than the most easily accessible controls on the unit. My only other gripe is the placement of the power switch, which is hard to reach when the USB-C cable is plugged in. As far as build quality and functionality, this device leaves nothing to be desired. It's very rugged, and the sound quality and metering is excellent. The ability to use a 32-bit depth isn't all that useful in the controlled circumstances of my own recording (the ~120-ish dB dynamic range afforded by a 24-bit depth is ample for drums, electric guitars, bass, vocals, etc.), but it's a good feature to have for anybody recording in unpredictable circumstances. Both the XLR mic-level inputs and the TRS line-level inputs work great, and the jack quality is apparent. I really like the captive XLR buttons (although with such a small device, I might rather the cable come out of the jack rather than having the whole device get yanked off of whatever surface it's on/attached to). I have yet to try any of the more music-focused features, but I have dedicated audio interfaces and computers that are almost certainly more user-friendly for those purposes. This will just purely be an audio capture device for video recordings for me. But it was nice of them to toss in those features anyways. Overall, I would recommend the MixPre to just about anybody wanting a flexible and high quality audio capture device. For my purposes of connecting 2 XLR microphones and a stereo line-level feed from another audio device, it has worked perfectly. Despite my couple of gripes, I'm really enamored with this little box.

Great quality sound, intuitive design, but one major issue

By alireza

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 either...it 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.

32 Bit float is amazing

The unit is great. I have had it a month now and used it on multiple projects. Still waiting for a timecode generator to test the Jam sync with the Komodos. I added the HiRose power plate to it for D-Tap and it worked well. My first test with with 4 AA batteries and 1 phatom powered mic, it killed brand new Duracell AA's in 20 minutes! Luckily there are a dozen different ways to power it. Their support is very responsive when you have questions.

32 bit float! Easy to understand menus and options. Newer firmware (7.15) also has some great features. Simple and easy--exactly what I needed.

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 sounddevices.com 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.

Can this trigger from a Canon EOS R if connected via the usb mini input?

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. My idea is that if I need to use channels 5 and 6, I can run a line from my Zoom F1 (which would have two mics going in) into the MixPre-6. Sounds easy enough, but am I missing something? Thanks for any insight.

when using dynamic mics with this unit will I need to use a cloudlifter or fethead?
Asked by: Richard
It’s got 76dB of gain for the XLR inputs. You’re probably referring to the notoriously gain-needy SM7b. I don’t have one but forum estimates place its required gain at about 60dB on average to maybe 66dB for quiet vocals. Here you would have even more if you needed to use that mic on a somewhat further source. Another thing to consider is the low noise of these preamps (-128dBu) which will allow you to safely boost levels in post.
