I really think SD should step up and actually offer some proper usb-c power cables other the massive dual usb to usb-c one they ship it with. By themselves or as a coop.
Some kits of 1,2 and 3 feet long cables with both straight and angled and low profile connectors. Which do not break and put excessive stress on the usb c jack.

The mixpres are a bag-able and desktop workhorse where the usb c seems to be meant as a desktop power option while in bag it should be powered by the 4- or 8- AA cell pack. Or via a could of different hirose battery adaptor options.
Yet many of us want to use the external usb c power banks - which is what have put us in this creative and inventive spot. :)

I've never had a lick of problems with this $6 right-angle USB-C cable.  I tuck it inside the left bar and it just stays connected forever.

No, USB-C > USB-C is not necessary! I am successfully running the MixPre on full power over a USB A > USB-C cable. The only thing that matters is the cable has to signal the MixPre that it is capable of carrying high currents. This is done using a a 56 kOhm pull-up resistor in the cable. And of course your battery needs to be able to supply that current.
SD have gone to great lengths explaining how to power the MixPres properly. I would not deviate from their recommendations especially given the chaos and nonsense in the PC peripheral market.

Deviating from standards, especially with power devices involving decent amounts of current is a recipe from disaster.

Most of the ways recommended by SD are pricey (L-mount batteries are probably the most solid) but they have identified a very affordable USB-C battery that seems to give good results, the Anker battery they mention in their tech note. I got one and it fits very well inside a Sachtler SN607 bag. With a bit of care the USB-C cable should be fine even though it's not so solid as a Hirose.

Not sure if Ive posted this before but these Tzumi (samsung) powerbanks are 42 bucks at best buy and come with a 3” usb c to c and a 3” usb a to c. I use an old r44 bag and the battery fits snug on top of the mp6 with the usb c cable at perfect length from battery to mp6. 20,000 mah and has an led readout for battery life. Never really get below mid 90’s with 4ch phantom. Think I used 2 at a 3 day festival last summer.

Hi, guys!

Would this charger -> https://www.amazon.co.uk/gp/product/B01MXXOQTE/ref=ox_sc_act_title_3?smid=A2PGPJL0BBLHLX&psc=1 be ok with Mix-Pre 3?
And another question:
Say I have two AC chargers with USB inputs (something like that: https://www.sparkfun.com/products/11456) in them. Would it be possible to use stock Mix-Pre 3 USB cable with two chargers like that? I mean one USB cable end goes to one charger and another one USB cable end goes to another charger. Or is it overkill? :)

I haven't got one. So if I buy random USB TYPE-C to USB cable and stick USB to random casual USB charger, will it be enough to power MixPre-3?

I don't know what either "random" or "casual" mean with regard to DC power.

Lot's of people claim that their usb-A gear powers they devices just fine, YMMV, but I wouldn't risk it.

I do know that in spec USB-C cables and chargers power the mixpre3 and micpre6 very well, as they too are in spec usb-c devices.

If you're going to pay $6-800 on the recorder, why not budget a few more dollars and grab the correct Anker battery pack? It's not worth potentially voiding your warranty IMO.

Can someone with the MX-LMount adapter provide/test the output voltage that is being sent to the recorder?  I am trying to determine if there is a regulator in there or if it is just sending the raw 8.1-6.8 volts to the device.

edit:  Answer from SD....

You can restore the whole unit to factory state by holding down the headphone encoder and CH1 fader while booting the unit. Note that this will reset everything.


I've done a factory reset by just going to preset > factory settings but apparently there are two types of factory resets.....
