^ You can also use Wave Agent to split off 3 and 4 into a stereo file. Actually, it will split a polywave into any combination of tracks you want.

[jbell]

Just use wave agent it is free and easy to use!  You can split them into stereo pairs in wave agent.  Then you can open the files in Wavelab and you will be good to go.  Wave agent will not work with 32 bit files.  I'm not sure why Sound Devices didn't upgrade the software for 32 bit recording. 

no 24 bit

Open it in audacity and delete one of the stereo pairs. It shouldn’t matter which one since you only had two channels to begin with.

I tried this last night in Audacity and it only gave me the option of exporting it as a mono file when I deleted the left and right recording.  I usually use wavelab elements 9.5 for editing but it wouldn’t even open the recording originally.( did not recognize the format). Audacity would open it and so did sound studio but sound studio wouldn’t let me do much of anything besides giving me the option to combine it to a two channel stereo recording. I don’t have wave agent maybe I’ll try that.

I think you had selected only 1 of the 2 remaining tracks. To export as a sterdo track in Audacity:
1. Import poly wav file
2. delete first 2 tracks
3. on top remaining track, click triangle at top right and select 'make stereo track' from dropdown
4. select your new stereo track and export as wav
5. profit

See! As many ways to do it as answers!

What's your power solution?

Now that we've had some time and experience with mixpres, wondering what folks have found best/most reliable for powering.

I've settled on Anker 10k power banks w 4AA sled as backup. 6" Anker usbc cable.

Other setups?

I've been using the Anker 747 without any issues. That said I am switching to the talentcell YB12011000-USB Lithium ion Battery Pack. Rather than carry two separate lithium batteries for the mix pre and a preamp. I can power both from one battery pack with the talentcell while cutting down on weight. Its also allowed on a plane for travel.

Thanks for all help fellas. This worked great. Thanks again

So I'm still on firmware V1.53 on my 6. If I jump to the latest version will I get all the updates that the came before? v7 has some good stuff. Thanks.

[checht]

Yes indeed.

So I'm curious about Sound Devices statement about over sized AA batteries:

https://www.sounddevices.com/using-oversized-aa-batteries-in-a-mixpre/

In their words, nonstandard. Aren't all rechargeables oversized? A couple YouTube videos about the battery tray not seating properly and causing power issues. I have a version 1 6 and never experienced any issues with the tray or any type of battery. Could this be a version 2 issue only?

[jbell]

I owned a Mixpre6 and currently have a Mixpre 10 II.  They use the same tray and I've never had a problem using Eneloop AA batteries.

I wonder if some of the oversize batteries are like the ones with built in USB charging ports which take up space?

I know that the lithium-ion 3.7V rechargeable 14500's have electronics which make them longer than a standard AA.

Similar size as AA cell. Those with a protection circuit are slightly longer.

Used in many LED flashlights. Nominal voltage is 3.7 V.

This YouTube video shows some rechargeable Duracells, which I have used along with Eneloops. I also have some rechargeable lithiums that don't have the usb input, that also work fine. My guess is they switched suppliers for the battery tray when the version 2 came out.

I have both a Mixpre-6mki, and a Mixpre-6mkii. The AA battery holders that came with them are identical. Sound Devices may have redesigned them at some point, but the Eneloop Pro batteries I use fit both samples I have just fine. I read that you can remove the center rib in the holder if you have oversized batteries you want to use, and the holder will latch to the recorder properly again.

OK first, do they mean overly WIDE or LONG batteries?
I was assuming long but the point about removing the rib makes me consider differently.


I guess you could grind away that rib with a rotating tool like a dremel!?
