Pristine audio
tacocat 07.09.2022
It's small, and designed for field use, which means there's some compromises that have to be made just in order to fit so much on such a small device.

Especially in terms of powering solutions, I am not a fan of AA batteries, and I'm not going to pay the asking price for a plastic sled to mount Sony batteries either.
You get very good operation times with just about any USB charge pack however, in my experience.
A 5V 1Amp pack is only able to power 2 preamps at the time, that's still plenty for my needs in most situations as I can still use the other inputs for line-in for instruments, etc.
My 10400mAh USB charge pack which delivers 2.1A for tablets etc. fully powers this for hours, should I need more microphones, and you get much larger capacity packs.

My only concern then is the USB-C prone to wear and tear, but it's somewhat protected by the XLR plugs going into channel 1-2, so I'm not too concerned powering it like this for now, but I'll want to invest in a bag with internal frame to protect it better and I'll fix a cable to the frame so it doesn't accidentally pull on the socket of the unit.

Overall I think they have done a great job in terms of fitting so much versatility and features into such a small device, and the quality is overall superb.
It's really well built, sounds crystal clear, very nice preamps.
Operation is intuitive and well thought through, the touch screen is very snappy. Very flexible in terms of various use scenarios. It's clear that Sound Devices have put a lot of thought into this.

Very happy with it, I'll be carrying it everywhere.


Professional, handy and easy to use.
ericberenguer 08.10.2019
This is professional, high quality and very compact device. I've been working with different hardware for a long time but I feel that I made my next with this one. I'm sound designer and I use to work doing field recording and processing and mixing sound in the studio. The Sound Device Mixpre 6 II allows with no complications move from home to outside with no problem, in a handy way and not bringing so much weight. One of the things that I really like of the second generation of Sound Device is that allows to record up to 32/192 giving me the option to transform more the sound without losing quality.


Amazing Sound Device
raffrack 20.05.2020
Superb pre-amps , the best sound card and portable recorder I ever worked with.
Just a con... battery last not too much.


Great Quality - Great User Interface
FabianHk 15.04.2023
It's small, the material quality feels sturdy and made for if it gets busy and hectic on set. With a proper V-Mount battery and a boom mic that always requires phantom power you get super long battery life.
With the recorder being small the touch screen and knobs are as well, you have to get used to that a little bit.
I think a good interface for a fast workflow is super important when it gets busy and this device excels at that. Having those 4 mic pre combo inputs at real 32bit conversion at that price is amazing.

That being said if you want to use a v-mount battery you need to buy the v-mount holder extra. It's quality is bad and it is extremely overpriced in my opinion, but since this is the review of the recorder itself it still gets 5 stars from me. Just be warned.
