Is there any real "danger" of using a cable that passes more power then it is supposed to be spec at?
I mean if your battery outs 2.4 and the mp6 is looking for 3, what's the potential issues??
I could see if the mp6 was looking for 3 and your battery was sending sayyyyy 7

The MixPre is not looking for 3A. It needs 1.5A at 5V i.e. 7.5W

A USB-C to A cable that has a built-in resistor to allow the MixPre to draw full power from a USB-A power source that can't deliver 7.5W could potentially damage your USB power source or cause the MixPre to not function properly. You use these cables at your own risk. Be sure that your USB-A source can deliver 7.5W (1.5A at 5V)
thanks for the reply. All the numbers I guess had me confused, for example the SD approved battery says it's output is 2.4 (3) on Amazon so I was thinking it wanted more than 1.5.

But if I am starting to uunderstand all this more and correctly, any USB battery that outputs 1.5A should work as long as the CABLE is made correctly?

This is a battery I have, https://www.amazon.com/RAVPower-Portable-Technology-Smartphones-Black/dp/B00XC1WAQ6/ref=sr_1_1?s=wireless&ie=UTF8&qid=1496935968&sr=1-1&keywords=ravpower+10000
It states it is "smart" and outputs up to 2A on each port based on device draw. Does anyone know if this type of battery would work?

Actually if the cable is made correctly, it won't work. Any cable with a USB A end that is built to spec should only pass 0.9A and therefore would only provide 4.5W (not 7.5W)

However if you buy a cable that is not made correctly (not to spec), it might pass 1.5 A and might work, but is not supported and may cause damage.

 "this battery paired with cable that can pass the 1.5A should work"

yes, the battery info says

Output: USB A1: 5V/2.4A max, USB A2: 5V/2.1A max



"any USB battery that outputs 1.5A should work as long as the CABLE is made correctly"

yes and no depending on how you define "correctly". A cable that passes at least 1.5 amps should work with any USB-a based battery that outputs at least 1.5 amps per port. This is not "correct" in the sense that such a cable goes against spec. Paul points out a scenario where using such a cable is a bad idea. If you plug such a cable into a port that can't output 1.5 amps you have a device wanting to draw 1.5 amps but cant - this is exactly why non spec cables have damaged equipment in some cases...


I realize how confusing this all sounds. I think I understand the issues at this point but feel free to correct me if someone finds out differently

Thanks guys, I got it now, I think ;)

So using USB-A, for it to work...
The cable must be made NOT to spec and could cause damage
The dual USB-A cable supplied from SD must be used

Using USB-C...
Those cables have a higher spec rating and so should work as long as the battery can output 1.5A

Totally agree. I'm thinking about starting a thread with what works in terms of powering options and run times

Thanks for the detailed info guys! If Paul said that can cause an issue, then I'm ordering the PowerCore 20,100mah that you and others have already bought, and used correctly! I'm not trying to break/ruin the ONE deck that's going to last me the next 10+ years hopefully, within the first 2 weeks of getting it, just because I wanted to try to use a USB A port :P ;) Thanks again for all of the info fellas! Before the MP6 came out, my knowledge of USB Batteries & Cables was elementary at best, and now that I've thrown away ALL of my old shit and bought new Anker stuff, I couldn't be ANY happier ;)

And would it REALLY be THAT HARD for SD to put on their site, that a USB C Port/Output MUST BE USED, so that the MP3/6 aren't damaged? I think that if it's possible to damage the MP3/6 just by using the wrong USB Batteries & Cables, that SOUND DEVICES should have MENTIONED THAT before a shitload of people buy USB A Batteries, and then have to return them like I have to do now, or even worse, damage their deck :P It only takes a SECOND to put that info SOMEWHERE on their website under the MixPre-3/6 web pages, so that it doesn't KEEP happening to people!

That said, I really appreciate Paul Isaacs@SD coming here onto TS.com and answering our specific questions. Without Paul coming here, we wouldn't know the specifics about the current that we now do ;D 8) So Thanks again Paul, you RAWK!!! :coolguy:

Totally agree with that Bean!  I think that it is/was negligent of SD to not have stressed the importance of using a specific combination of "accepted" components to power the new MixPre series without risking damage to the equipment.

OK, just added this to my Cart and I'm buying them as soon as I get the rest of my PP $$ together soon 8) I am just getting the extra Anker Powerline USB C>C cable because it's badass, and should be a fast enough cable@60w to last me a lifetime for the MP6 or any other C>C devices I have[my Google Pixel phone] so that I can charge and power as fast as possible! I wonder if this cable WILL or WON'T work with the MP6 though? It goes UP TO 60w, but should be just fine supplying the 7.5-15w that the MP3/6 needs, right? And you can't beat Anker giving you [2] cables with the battery below that SD recommends! A USB A>C to charge the battery[from my Anker PowerPort 2 & 6], as well as a C>C cable to power your device[MP6 in our case]. Anker, I love you lol ;D Anyway.....

Thanks again to JohnW and Rippleish and Paul Issacs@SD, as well as everyone else who helped figure out the best MixPre3/6 USB powering options, so that the rest of us know exactly what to buy and what NOT to buy! +T Fellas for being the guinea pigs lol ;D 8)

I also like the power button for the above battery being on the top of it, vs the side power button of most of the PowerCore Batteries, since it seems the above battery won't accidentally turn ON/OFF as easily as the side button PowerCore batts, where it seems like that would be easier to occur?!

i have the omni pro battery and a right angle up down cable that work great. i feel very confident in this . i've run this for 8 hrs about three times . no heat or any problems .i bought a dummy np battery that i will use with the l sled and the omni charge. this will take the fear factor about the usbc away. But for those that have the omni charge i think you will be fine. just my 2 cents!

Numerous people have posted about this in the regular Mix-Pre thread. There are a lot of variations. I believe all the postings were about using a 2 phantom powered mics. I personally get about 2.5 hours, but less if the rechargeable batteries I'm using at any one time have already been recharged numerous times over the years. Some folks get less, a few get more. Of course if you are using dynamic mics you should get a lot more time out of batteries.

Got my MixPre-6 on Thursday. Really nice machine.

I've had to spend a lot of time figuring out the system so as to record in my usual setup. So this morning I finally did a battery test.

Running the MP6 at 24/192, recording only on Channels 1 & 2 (did NOT record the MIX LR tracks), phantom power on both channels, Bluetooth OFF, LCD at 1, LED at 2, using POWEREX Imedion 2400 mAH NiMH batteries, I got 2h16m runtime.
