Topic: Sound Devices MixPre-3 and 6, Part 7

I have mixpre-6 and mixpre-3ii, they have exactly the same the battery sled.
I don't know which ones from whom.
Eneloop AA  work great without any problems.

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!?

Every comment I’ve read referred to the batteries being slightly larger in diameter than the “standard” AA dimension. This would cause the holder to swell along its length, preventing the holder and its latch from fully engaging. I imagine the plastic would be soft enough to nip out with some cutters, but I’d go for sawing it out with a rotary cutter blade on a Dremel tool.

The Sledd in my 6 (one of the early ones and on top in the pic) holds ikeas or Eneloops no problem. The Sledd in in my 3 ii (bottom pic) doesn't like them. Definite bulge in the center where the plastic divider sits. As seen in the pic, the older Sledd has no center raised divider section. I removed it on the newer one and problem solved. As I said in an earlier post, they definitely changed suppliers or the design of the Sledd.

Maybe they did it at some point.

My guess is they switched suppliers for the battery tray when the version 2 came out.

My mp-6 was bought a year after the release, and mp-3ii was bought a little over a year ago.

Even empty, 4AA sled on my mp-6II doesn't snap in as well as sled from MP-3 did. Noted it during unboxing.

Seems to work fine, though. With alkalines and eneloops.

Cost saving action into lower quality plastic?
Not POM anymore?

Setting up my MP3ii for 32 bit recording. Since basic mode doesn't work in 32 bit, I guess custom mode is the way to go?

Channel>Advanced.
Gain>Basic.
Record>Advanced.
Output>??
Metadata>??
Headphones>??

I'm guessing the last 3 don't matter. Maybe output to advanced? What about advanced mode? Never really used it on my 6i because of gain knobs being disabled. Also, what software editing programs will work with 32bit poly wavs. Wave Agent doesn't separate them, I guess. I have Adobe Audition 3.0. Does that do them?

Thanks!

I set everything to advance with the exception of gain that is basic!  I use RX8 to separate tracks, but if you want free Audacity works.

to set up for 32 bit you will need to be in custom mode. Once you switch it over for 32 bit you can make a couple of changes. If you are running an external pre you need to change your channel over to line vs mic. If you are just running mics straight into the MP leave it on mic. You can also control phantom power and low cut filter. Several tutorials here is just one dealing with 32 bit

As for post processing there are several threads that deal with your question(s). Rabbit hole can get deep.

Audacity,
Isotope rx
Reaper
wavepad
and so on....

Thanks for the replies. Just thought of another question. If I'm only doing 2 channels, but not in basic mode, do I still get stuck with separate poly wavs? On my 6, if I'm only doing 2 channels I stick with basic, but when doing more I switch to custom and deal with wave agent.

If you are doing a 2 channel recording it is just a stereo track as long as you have the mix disabled.  You treat it as you would any other stereo track.  I always keep gain in basic mode no matter how many channels I'm running.  Everything else should be left in advanced.  If you set it up this way you won't run into any issues and the gain knobs work as they should.  I would also suggest linking the gain knobs.

Thanks jbell! So the linking and mix disable. Where actually are those two set in the menu. In the record tab I see L&R linked, L&R, L, R, Off and Off & Linked.

Menu #2
tap record
tap Rec L,R
screen #2
tap off... you're done with mix disable

to link channels... press on channel 1 (to link 1-2) channel 3 (to link 3-4)
go to screen #2... Linking is in lower left underneath phantom power

Here's an xml file for recording 2 mics w p48 @32bit, linked, no mix record.
TS doesn't allow .xml, so I changed the extension to .txt. You'll need to change it back to .xml to load it...

Edited to add: Firmware 7.13.

Is anyone using the MX-Hirose sled? Looks pretty solid. Expensive though. Is there a battery with a more solid connection than a USB on the battery side that could be used with this sled? It would be nice to have solid connections on both ends of the power supply.
