Does the job but very expensive for such a simple piece of kit

krnpwr 28.12.2020

As above, this piece of plastic does what it is supposed to do, but is very over-priced fir what it is. It clips neatly into place and of course the mix pre is practically unusable without the L-Mount batteries. Therefore the cost of your mixpre-6 II is actually over €100 more expensive for those looking to use this device for any kind of onsite recording. Delivery and order system with thomann was excellent and without fault. I will also say that Thomann's price is in line with SD, so my objections do not lie with Thomann.

Since I plan to do field recordings where no 220V power supply is available, I need a reliable power source that lasts at least

Urmas Punane 05.02.2025

I started using it and will share some initial observations.

First, the negative – power supply:
4 x AA batteries are definitely not a viable option for powering the Sound Devices MixPre-6 II!

With a fresh set of 4 x AA batteries, I was able to update the firmware to the latest version (in my case, MixPre_9.02), and after the update, the brand-new batteries were already drained!

I then replaced them with another set of fresh batteries from the pack, and I could maybe record for about a minute using two phantom-powered microphones before the battery indicator dropped rapidly, and the device started complaining that fresh batteries were needed!!

After reading other users' comments, I initially couldn't believe it was this bad, but I ended up ordering the following on the same day:

Sound Devices MX-LMount
2x SupraCell Sony NP-F970 batteries
A dual charger for these (SONY NP-F970 Dual)
Since I plan to do field recordings where no 220V power supply is available, I need a reliable power source that lasts at least 3 hours!

On the positive side:
The sound quality is superb!

Too expensiv

Sheik Yerbouti 19.03.2020

Ok, let me first say that the MixPre II is a fantastic mobile recorder: nice analog limiters, 32bit float audio, good haptics, sturdy built...a great product.
The Mixpre’s just have one flaw: Powermanagement. Forget about Alkaline batteries, the Mixpre‘s eat them for breakfast: between your first coffee and your cereals the batteries will be gone. What about USB-C then? Well, this is very good to have. But you cannot rely on a flimsy USB-C connection for live recordings as the cable will come off too easily.
So, then we have the MX L-mount. This is a reliable, professional solution which depending on the NPF batteries in use can last you a whole day of shooting/recording. But the battery mount in essence is a lighweight piece of plastic which does not easily connect with the Mixpre’s. Each time I am removing it I am concerned the brackets come off. A price of €25 for this thing would be fair and would still give Sound Devices and its resellers a healthy margin. A price of €50 would be steep. A price >€100 is just excessive. This is where the Zoom F6 has a competitive edge!

Indispensable

Comment alimenter dignement le Mixpre sans risque ? je sais par expérience avec mon MAC que l'USB-C (vu sa petite taille) ne tient pas bien en place, encore plus sur un appareil comme un enregistreur dont la vocation est d?être mobile. Au lieu de la batterie externe et la connection l?USB-C, j?ai donc opté pour le MX-Lmont. Heureusement pour moi, car le Mix pré avec son écran et ses alimentations fantômes est gourmand en énergie. Avec 2 batteries de taille F550, j?ai une autonomie d?une demi journée (4 heures). Avec des batteries plus grand que la F550 l?appareil devient encombrant et lourd.
