The only time you might benefit from the XLR outs is nature recording, spoken word or reeally quiet music.

...or when the other output is busy giving someone a feed

New firmware release with some good stuff for MP3 owners

New MixPre v9.00 Firmware Includes New Product Features and Plugins

MixPre v9.00 firmware is now available for download from the Sound Devices website. It includes an array of new features and capabilities, including:

Two-instance NoiseAssist plugin available for the MixPre II Series in the online store. 

New +2 Channel Plugin for the MixPre-3 I and II that expands them from a 3-channel/5-track recorder into a 5-channel/7-track recorder by adding mixable and recordable channels 4 and 5.  

The ability to have both timecode and audio output on the Stereo Out 3.5mm connector on MixPre-3 II and MixPre-6 II.

A full slate mic routing matrix added to the MixPre-10 II. 

And much more!

[mccordo]

I saw this and am excited but unsure about jumping in right now with turning my MP-3 into a MP-5. It's only a $79 plug in, so the price seems well worth it, but I just want to see if someone else does it and how it works for them.

[ts]

Yea that's crazy. I just sold my 3 ii. 

[checht]

Talked we SD support, and the +2 adds channels similar to 5/6 on the mp6.

Access to settings is by pushing in the knobs for channels 1/2.

Sounds pretty cool.

[mgtaper]

I updated my mix pre 3ii to the new firmware and added the +2 plug-in! 

Very excited to give this a whirl in a few days!

What kind of bag are y'all using for your Mixpre6? Need enough room for the usual stuff - clamp, shockmounts, tbar, batteries, cables, sometimes enough for 2 pairs of mics.

I used to have a Petrol Pegz2 that worked great for my Tascam DR701d which was a similar size and layout.

I’ve been looking at the Orca OR-28 (https://www.orcabags.com/product/or-28-mini-sound-bag-for/). It’ll fit either the MP-3 or -6. Right now I’m using a clear stadium bag with a layer of foam on the bottom.

Have been using an RM-Multi as my bag for my MP3, has just enough space for actives, cables , batteries and small windscreens.

Going to have to get the +2 plugin. Was one of the missing features between the mp6 and mp3 I always thought was odd.

So how would you have to outfit the Mixpre3 in order to use the extra channels?  I guess you'd need to use either powered mics or a line in signal into the Aux/Mic in jack?  I'm thinking if you have a stereo XLRF > 1/8 mini Y cable, you can also use it to get L and R from the soundboard...SBD > normal XLR pair > Y cable > Aux/Mic In? 

Am I thinking right here?  Any other uses?

I’ve got one. I’m just thinking of creative ways to use as much gear as I can while still maintaining a relatively small footprint.

[justme]

I believe that this additional +2 plugin really shines for the streamers, podcasters and studio usb i/o usage.
As the USB 1&2 input can be routed to the new channels 4&5 which free up the ch 1-3 for microphones.

Of course...but the +2 plug in is for those of us that already have a mixpre3.  Also, some people might want to opt for the lower cost of the mixpre3 + plug-in over a mixpre6, say if their only need was for 4 channel recording.

[Popmarter]

Just updated my mixpre 3 II and added the +2track plugin. Anyone here used this in a real situation? What options are there. There is talk about two aux inputs. Call me stupid but I only see 1 (do they mean it can be uses a aux MIC and aux Line?). What makes up the five channels, 3 x xlr, 1x usb and 1 aux?

Any suggestions on how to run a 2 XLR soundboardfeed and a set of Schoeps+babynbox? Maybe this: SBD > XLR in. + babynbox > aux in?

[justme]

You should be able to use the xlr for 1-3 and the 4-5 (+2) from either USB-1/2 or aux in 1/2.
They can be recorded as iso and to the mix.
Also they can be controlled as other with low cut, arm, gain fader, pan etc and have other plug ins applied to them.

^^ Exactly. Your MixPre-3 should now be just like my MixPre-6 in terms of you can now plug a 1/8" aux-in TRS into that has 2 mic channels L/R connected to it, and that can be your ch. 5 and ch. 6. You can also do USB-1 and USB-2 as ch. 5/6, but that is maybe less useful if you are on this forum. The upgrade is supposed to make the MixPre-3 like MixPre-6 and MixPre-10 that already had these options.

I use this and it works great.  Faster than the other one I tried but it does add time at the end of the night.  Sometimes I'll just leave the deck on in my bag after packing up.

If you're formatting the SD card I would still want a 2nd copy just to be safe.

If you are in a hurry to strike you can shut down as normal. When you next power up the MixPre it will resume copying to USB.

I won't format the SD card until I'm home and have backed up to my Mac. Sounds like a viable option and will allow me to lighten up.
On a long tour, every bit of weight matters now that I'm AARP-eligible and have back issues 😀.

[GLouie]

The slowness of the USB backup can be a little annoying. I also like to use file transfer mode to copy the SD card files instead of having to remove the batteries to physically get to the card. It's too bad the USB speed is limited to USB2, despite the C connector.

(edit: re: MixPre10ii. I was told not to make a new thread for the MP10)

[checht]

Manual has info on 'suspending' the copy by powering down, then resuming by powering and hitting record. Seems like a solution for the slowness.

Will report back on how reliable this is.

... but also, I run a fairly complicated setup and it takes me a while to break down. Might be a good match, timewise 😀.

[Gordon]

Going from memory here but you can also stop it by hitting the flashing record button (it flashes while copying) and answering the prompt to stop.  Next time you turn the deck on it will resume.

[vantheman]

I would like to find an attachment with 1/4” threading that I can use to mount an Anker battery to the MixPre6ii. I’m really not crazy about the two being connected only by USB wire and I’m actually surprised I haven’t had the battery accidentally disconnect yet. Does anyone have a solution for this?

[jbell]

This is correct!  Hit the record button and it stops the backup process.  The next time you turn it on backup will start again.

@vantheman - would the tether block from Tether Tools work for you? It's intended to keep a USB cable from being disconnected from a camera during tethered shooting. It won't mount the battery to the recorder, but would tie the cable tightly to the bottom of the recorder. It's a little pricey for what it does. My current cameras came with dedicated cable brackets and the clunky Block has been relegated to my just-in-case-pile.

Manfrotto cell phone mount would probably work depending on how wide/thick the battery is

I used a cell phone holder with a clamp to hang it from the mic stand when I used one of those anker batteries for my f3, and a 1/4 thread clamp to hold the f3 to the mic stand as well

I use small cloth drawstring bags for gear in the pack. Battery in a bag, bag hanging by drawstring from the stand or recorder mount. Light and no cost.

I have 2" of 1" velcro tape on my mp6 and my batteries. I also use a 3" usbc to usbc cable. Nothing moves at all. Ive had the same setup since 2017. I also wanted to ask, when you guys say the file transfer is slow via usbc, is 2 or 3 minutes considered slow? Ive never removed the SD card I initially popped in it when I got it and just do usbc File transfers.

[checht]

Just did a speed test. 2.64GB file, 4 channels of 24/48 for 57 minutes.
Took a bit less than 6 minutes to transfer to USB stick.
Takes me longer to break everything down, so ought to be just fine.

I had connected a USB stick to format it for mp6. On powerup, the record light flashed; I pressed it and it transferred the last recording, made 12/5, to the stick.
Why not just shut down as usual, then backup to USB later? For folks that don't like the wait, wouldn't this be a solve?

[Gordon]

I've been using a Anker 20500 USB C battery to power my Mixpre6 with 4AAs in there as backup. It powers it for about 3 long shows with room to spare so that's all good. But it's a long, skinny and very heavy design that I'd like to not have to shlep with me at Jazzfest this year. I swear it weighs twice as much as the recorder.

Does anyone use the hirose adapter sled? I have a hirose cable that fits a Talentcell 12V battery that's a better form factor and high capacity. $120 for the sled seems like a lot. It fits in the space that the AA sled fits, right? Goofy question but does it also have space for the AAs for backup?

(EDIT- from looking at the pics I can find it clearly doesn't have room for AAs. That's not ideal only having one power source if using this thing to avoid using the USB power input)

Anyone have one, either the SD or Hawk Woods version, that they want to sell?
Or can point me in the direction of a battery that's USB C capable that isn't a wonky form factor and 3 lbs like my Anker 20500?
I'd really like to just take one Talentcell and be able to run my Mixpre6 and Oade DR100 from the same battery.

[jbell]

The hirose sled takes away the ability to use AA backups, but you could use the usbc for back up.  When using the hirose sled the Mixpre battery meter doesn't function correctly, but you have a meter on the Talentcell so that shouldn't be a problem. The cable technics version is a little cheaper.

[todd e]

i do run the hirose + talentcell and get insanely long run times. 
sure no backup, but and this is the BIG BUT - the cable locks to the deck/jack. 
i also run a 2nd talentcell for the vms02ib + m248 battery backups, both are powered internally, but never can be too safe

wish more cables did, i run the 4pin xlr for other bag toys and the benefit of the lock cannot be overstated. 

clearly its something SD agrees with me on, by insisting on locking XLRs for the mic-ins

[dallman]

I run both Sony style batteries on the back, and a variety of USB_C batteries in my MixPre6 II. I use an "L" shaped Male to Female USB-C cable that is always protruding from my MixPre6 in essence extending that input out to where I can easily get to it. It's been lot's of years and recordings and I have never had any issue with it becoming loose or getting pulled out. I would not want to give up the 2 power options just as we know at some point a battery will fail or I will miscalculate or forget to recharge, so the backup of having the Sony style batteries and the USB-C batteries is what I prefer.

I’ve used some of those to run 12V taper gear. 15V is enough to run and charge my Toshiba laptop albeit slightly below spec

USB does not support 12v directly

[breakonthru]

USB PD standard has been around for over a decade, and has become ubiquitous in battery banks in the last few years

the newest 3.2 standard introduced a few years back supports up to 48V though 12,15 and 20 are far more common voltages in the many PD devices on the market. Generally the max voltage is loosely tied to battery size you don’t see batteries under 10000 mA pushing out high voltages because the current draw exceeds their design spec

I have 10000 ma batteries that push 12 and 15V but the only ones I have seen that push my laptop a proper 20V are 20000 mA power bricks and above

https://www.usb.org/usb-charger-pd

Of course 5V is no more natural from a battery than higher voltages, as all are stepped up from 3.7V cell voltage

There are numerous cables available to provide negotiated fixed voltage out of a PD-compliant USB-C jack. There are more advanced cables which offer user-selectable voltage as well. The fixed voltage cables are cheap (<$10) and feature the standard 5.5mm x 2.1mm and 2.5mm barrels.

10000 ma batteries are a good match for mic pres/ADs that either want 12V (lead sled era) or is flexible on input voltage (RME gear takes 9-18V) **users must be careful to use a cable with a fixed upper voltage matched to their equipment. A 20V cable may provide 12V out of one battery then you plug it into a larger battery and watch the magic smoke exit your device as 20V is applied**

The newest PD standard with EPR and AVS can actually provide any voltage from 5V up to 48V in 100V increments

Thanks to checht for pointing out the anker spec page. Voltages are typically left out of the Amazon listings but as a top-tier mfr their website actually has good details. Their flagship power banks (24 and 27000 ma options) output 28V at 5A  on each of the USB-C ports and their 20000mA batteries top out at 20V

[morst]

Oh I forgot abut USB-C, yeah it can do like 100 watts so I guess it does have to be able to make higher voltages than 5V.

I don't own one of these, but I'm hoping the thread doesn't mind a quick question:

When in 32 FP mode, do these recorders lock analog gain to a fixed level, with only post-ADC digital signal level remaining adjustable? Or can the actual preamp gain still be adjusted in this mode?

There's a discussion on the Zoom F3 thread where a few of us are trying to clear up confusion caused by a poorly written manual. Zoom F series locks preamp gain to a fixed level in 32FP mode; I'm wondering if the MP-II series behaves the same way.

My understanding has always been that on the MixPre 6II, you can adjust the gain. Here is a quote:

You can adjust the input gain levels by using the gain knobs located next to each input. Turning them clockwise will increase the gain, and counterclockwise will decrease it.

That said, It really does not matter as I have found little or no difference in the end result if I set gain high or low. The move in post to put the output volume (fader) where I want it results in a clear and non distorted sounding file, just like the F3 or F6 which I also use. I know some will disagree which is fine, but these are my impressions after using all 3 decks quite a bit.

[commongrounder]

I own a Mixpre-6II and a Zoom F3, and I agree with dallman. I have done analysis of files recorded on the Mixpre in 32-bit float mode, and I have determined that there is no *analog* gain adjustment being made when using the trim or mix knobs. The entire 142db dynamic range of the outstanding Kashmir preamp can be captured in each sample, no matter what the setting is (except for “off”, of course). The front knobs main function is to digitally mix the iso tracks into the stereo mix tracks. If “gain” is set to “basic” in the custom advanced menu, the front panel knobs digitally set both the mix level and iso track level. I think of the level controls on the Mixpre in 32-bit float in the same way as I do the “magnification” on the F3, just (essentially) continuous rather than stepped. I set the Mixpre levels to a healthy meter deflection to allow comfortable monitoring. A big difference with the Mixpre from the F3 is one can change the levels during recording. I do have to say, however, I’ve long felt (even since analog days) that level changing (“riding the gain”) during a recording is a big no-no, so I am extra averse to touching the knobs (except in an emergency) once recording has commenced. 32-bit float technology has reinforced that feeling. But that’s just me.

I try to never change levels during a recording if I can help it. Pain in the butt to level out the volume changes later. With modern gear (anything over 100 dB s/n) I’ve never had a recording that was lacking for levels to be too low. Ambient noise is way above microphone noise which is way above the noise floor of the input.

It's a post-processing perspective, but we live in a time where DAW software is a free download, and hard drive space is relatively cheap compared to audio recording file size!!!

Ran a test for Greensky Bluegrass with my MixPre 3 with the added channels upgrade. I own a MixPre 6 too and know that it can be used to run 4 XLR mics, but I wanted to test out the 2 extra channels on the MixPre 3. A pair of AKG ck63 went direct into channels 1 and 2 via XLR. Then AKG ck61 > MixPre > 3.5mm tape out > MixPre 3 channels 4 and 5 via 3.5mm aux in. I set the levels on the MP3 at 0db for channels 4 and 5 and used the MixPre to adjust the levels.

The metering was just like running 4 channels on the MP6, although it was 5 channels with channel 3 unused. Everything worked flawlessly, although it was funny to see the ck61s as channel 4 and 5 in post instead of the usual 3 and 4. Overall, I was quite pleased with the process, although I HATE being forced to set up under the balcony at HOB Orlando.

Thanks alot for the report in.  Nice to know that everything works well.  I'll need to pick up an XLRF x 2 > stereo mini and then buy the plug-in.  You never know when a SBD feed might be available to grab on the fly.

A couple of questions, if you don't mind:
 
Obviously, on channels 1, 2, and 3 we set levels with the gain knobs, but IIRC you can also pre-set levels in a menu (or maybe that's another recorder...hmmm it's been awhile since I've been out).  So when you said you used the mix-pre to adjust levels on Ch 4 and 5, do you mean there's a menu option that allows you to move levels up and down? 

Are they individually adjustable for each channel? 

Can you gang all of the channels for gang level changing?

Is level setting on Channels 1 and 2 menu selectable in the same menu's as those for Channel 4 and 5?

(Sorry for being lazy and not checking SD's website to answer these questions myself, but they don't give a whole lot of details about the details of the plug-in.)

That's my next purchase now that I got the extra channels. I was using the 3.5mm out on the MixPre 3, but having an XLR > 3.5mm would be perfect for this setup to take a SBD feed or run an extra pair of mics with an external preamp in a pinch.

Correct. The front knobs still control channels 1-3, including arming/disarming and raising/lowering the gain. To control Channels 4-5, you have to open the menu and go to the submenu for each channel. The headphone knob changes the gain and the arm/disarm is on the screen (iirc). I set channels 4-5 on the MixPre 3 at 0db and used the MixPre to adjust the gain of the signal coming into the MixPre 3.

Are they individually adjustable for each channel?

Yes; each channel is individually adjustable. I'd like to find a way to adjust channels 4-5 without having to go thru the menu, but I haven't figured out if that is possible yet.

Can you gang all of the channels for gang level changing?

I'm not sure if you can gang channels 4-5. It sounds worthwhile, so I'll see if that's a possibility.

Is level setting on Channels 1 and 2 menu selectable in the same menu's as those for Channel 4 and 5?

No; channels 1-3 still use the front knobs. Channels 4-5 use the menu to make adjustments.

[commongrounder]

Some clarifications to mccordo’s post.
The Mixpre-3ii can only gang inputs one and two. The 6 and 10 allow other channel ganging combinations. There is a shortcut to get straight into the channel 4 and 5 adjustment menus. Press the headphone/select knob and then press either the front panel channel 1 or channel 2 knob. 
A feature that is new in firmware 9.02 is the ability to adjust the gain on the aux inputs separately from the mix level to the mix tracks. Previously, the mix level was fixed, so gain adjustments necessarily affected mix levels. I don’t record my mix tracks (only the iso tracks), so it was never a big issue for me.

[Gutbucket]

I've a question on ganging channels-
Can that be done in such a way that the various channels of the ganged group retain their relative levels, even as the levels of all channels in the group are further adjusted in unison (like Tascam DR680), or are identical levels forced across all channels in the ganged group? (Like Zoom F8)

[jbell]

I believe you can set it up either way!  I have mined paired 1&2  3&4  4&6 7&8

I'd think you'd handle that with gain, the ganging should only affect level.  If I get bored I'll test that on my f6.

[Gutbucket]

Yeah gain trim.  Won't be quite as applicable recording in 32 bit as it is when recording 24bit. Yet still will somewhat because when using mics of varying sensitivities its helpful to set their gain trims differently to compensate and achieve a good baseline level across all channels, then maintain those relative gain differences while adjusting trim of all ganged channels simultaneously with a single knob. 

The second part is not as applicable in 32bit, but the first part still is.  I suppose setting level or "magnification" differently for the various mic channels will achieve the same end result, by retaining the desired relative level difference between channels in the file set.

I never ever record the mix tracks, but I would love to be able to reduce their level so they don't show peaks on the Wingman app! #distracting

It is easily possible to adjust the mix track levels. In the menu screen navigate to the second window, and then tap “record” (This is where you were able to disarm the mix track recording). There are also two buttons for “Left Gain” and “Right Gain”. These will adjust the mix track overall level. You can reduce the level by as much as -30db, which will make the mix track meters much less distracting. Just remember that if your headphone preset is routed to listen to the mix track output, that level will also change with the mix track level. I have made headphone presets that listen directly to the iso tracks, therefore avoiding this issue.

[fobstl]

Great tip commongrounder 👆. This is why I love this group!

[morst]

Ok that will have to be good enough. If I can’t shut it off, at least I can attenuate away the peaks.
Thanks for the tip!

Yep, I often use the ISO track headphone outputs to listen to my different mics on the drive home

Using headclamps headphones like Vic Furth drummer's isolating phones, I listen to the ISOs during shows. I'm usually side or backstage, so don't have as much PA to ignore. Helps me level-match vocals, mostly. I often put all the vocals on 1 of the 2 monitor mixer aux busses I get, and guitar/keys on the other channel. Don't like/use a full multi matrix out, just things to improve presence and add texture/tone to instruments.

[checht]

My mp6II has an issue that SD has isolated to hardware, wondering if anyone else has seen it.

If I power up with a plug in the aux jack and signal present, the mp6 pegs channels 5 and/or 6. Removing the plug doesn't fix the issue, I have to power cycle.

I'll send it in after current tours are done but wondering if anyone has seen anything like this.

Also, thanks commongrounder, reducing mix tracks gain is super helpful!

[goodcooker]

Not sure many folks using Mixpres like we typically do here would find this particularly useful but I just found this out. The Korg NanoControl 2 usb midi control surface is plug and play for a lot of features on the Mixpre. I got one for drawing automation in Reaper for multitrack projects and while searching Youtube for videos on how to set it up I came across a vid that shows how it works with the Mixpre10ii.

It's a pretty small device that has 8 faders and knobs each with a dedicated Solo, Mute and Record Arm button for each channel plus a set of transport controls and marker buttons. Upon connecting it to the USB of my v1 Mixpre6 it automatically recognized it and sent it the commands to operate all the features. The faders control gain and the transport, marker and other buttons work as expected. Depending on which recorder you are using and what firmware you can configure the knobs and faders to do different things.

I don't see a lot of tapers using this device since it's not very bag friendly but dang, it never ceases to amaze me how far we've come in such a short time since hauling SLA batts and saving up for a Grace V3.

^ Interesting!

How is physical sync between Korg faders and MP faders accomplished? No motors in the mp, so ?

Asking primarily b/c SD engineers cite this issue as the reason that wingman doesn't deal w faders/levels.

Thanks

The fader knobs on the Mixpre don't move just a change in value on the screen. I have to fool around with it more to see what happens when you use the fader on the control surface to change the gain but then start moving the knobs on the Mixpre. Depends on how you are running it too, probably. Custom mode may do something different than basic, etc.

The MP faders are encoders not potentiometers, so the position does not dictate any "value".

I also have a NanoKontrol2. When the MixPre detects the presence of the controller, it disables the knobs on the recorder, as well as menu pan and solo control. Arming is still possible from both the menu and the control surface. It’s a pretty handy little device, as goodcooker has said.
The MixPre gain knobs, BTW, while technically encoders, have stops on them so function as potentiometers.  The side headphone/select knob is, however, a true encoder.
The Wingman issue is interesting, because if it assumed control of the gain pots, and was at a distance from the MixPre, there would be no local control if someone needed to make changes at the machine in a hurry. Sound Devices probably felt that wasn’t acceptable. The control surfaces are at least tethered to the MixPre by the USB cable, keeping them relatively close.

[Gutbucket]

^ Not sure about this one specifically, but in many implementations where an alternate set of non-motorized encoder is able to be used in parallel with the primary encoder to  control the same variable function, control of the function is 'handed off' back and forth from one to the other in the following way-  The encoder which has a physical position that doesn't match up with the current value of the function doesn't immediately become active as it is moved, but 'takes over' as soon as it passes the 'sync-up point' with the other encoder.  That encoder then remains active until the other one is moved past the new 'sync-up point'.  In this way control over the function remains smooth, rather than suddenly jumping to a new value each time the 'other' encoder is moved.

I still have more testing to do but with the control surface connected it disables the knobs. Turning the knobs does nothing. When the control surface is disconnected it behaves very much like what you are saying with the physical location of the knob matching up with the setting it was left with by the encoder before any values change. That way it doesn't jump to a weird value - like when physical gain knobs that control digital gain are moved when a recorder is on hold then all of a sudden when the hold is released it jumps way off. My Tascam DR701d was like that - a knob got moved while it was on hold and when I took the hold off one channel was brickwalling like crazy.

[commongrounder]

I confirm, as goodcooker has stated, that the front control knobs are completely deactivated while the control surface is plugged in. I checked this to be true on both my MixPre-6 original and MixPre-6mkii recorders. Unplugging the control surface “hot” immediately jumps the gain to level normally set by the knob, wherever it may be. Hot plugging the control surface IN has a different behavior. The gain drops to zero/off no matter where the surface faders are set, but jump to their level setting as soon as they are moved. I’m not in the habit of pushing in or pulling out connections while the recorder is powered up, but it’s interesting to see that it can be done without crashing the recorder.

Was just poking around on the SD site to see if there was more recent firmware than 9.01 for my mixpre 6 original recipe... (nope, not yet)
I typed in my serial number and found that I have a license for the Ambisonic plugin, from 2018!

Does anyone else have the Cable Techniques MX-Powersled and a MixPre 6II that is having trouble getting the sled to click in place? It goes in the slot, but will not snap in place and can easily be pulled out of place.

I liked the metal housing but if this doesnt work, will be getting the plastic SD version.
