I've scrolled down the forum a fair way but can't see this one mentioned.   Forgive me if I've overlooked an existing topic.

"The ZOOM M2 MicTrak Stereo Microphone and Recorder combines two cardioid microphones in an X/Y position with a quality microSD-compatible field recorder. This all-in-one design makes it a convenient solution and it also includes the ability to record in up to 96 kHz / 32-bit float.  The M2 MicTrak was designed to fuse the professional guts and features of the F-Series recorders with the convenience and portable form factor of the Handy Series. This middle road allows the M2 to provide excellent functionality at an attractive price."

https://www.newsshooter.com/2022/12/15/zoom-m2-mictrak-stereo-microphone-recorder/

$199 US - https://www.bhphotovideo.com/c/product/1737327-REG/zoom_zm2_m2_mictrak_microphone_and.html

And there's an M4 also - https://zoomcorp.com/en/us/mictrak-recorders/mictrak-recorders/m4-mictrak/ - four tracks with timecode.  It has  built in stereo mic, XLR x 2 inputs, and also seems to have a 3.5mm stereo mic input.  This perhaps is the device most likely to be of interest here but it's more expensive than the other two models. 

And an M3 for on-camera mounting, which interests me more than the others.  https://www.amazon.co.uk/Zoom-M3-Microphone-Shockmount-Compatible/dp/B0BN4D8GCH
https://zoomcorp.com/en/jp/mictrak-recorders/mictrak-recorders/m3-mictrak/

That also seems to be only $199.  There's a YouTube video at https://youtu.be/4A3S1tuq2GQ showing it being used with its post-production width control for pipe organ recording.  This I find impressive, except that when it's set to mono, it's actually 120 degree stereo.  This could be an error in the video - or a bug in the mic or software which Zoom should have spotted!

"It's just a mic that I happened to have in my pocket, Mr Security Man.  I haven't got a recorder with me to connect it to."

I'll leave you to google for other links - or not, if you think it's not in the least interesting!

I ordered the new 32 Bit Float Zoom M3 MicTrak Stereo Shotgun Microphone and Recorder for my camera since I do concert video. Should be here today.



Me jealous?  Of course not... it's not available here in Australia until February.  I could get B&H to ship me one though... I have to say that having started recording using an EMI L2  recorder (with valves)  https://reel-reel.com/tape-recorder/emi-l2/ and having once intterviewed Sir Yehudi Menuhin at his home about his days of recording on wax discs - for which I used a HHB Portadat which intrigued him - being able now to buy a one-piece 32 bit float camera mounted mic/recorder does amaze me.  I look forward to your feedback in due course!

I don't think that comment was directed at you.  What annoys me about that guy's videos are that they make all sorts of assertions with limited comparisons and they are at variance with all (that I've seen) other end-user samples and reviews.  Why is his different?  Why is his the most credible review?  But he seems to be surrounded by fan boys who then post adverse comments on the official Zoom channels on the basis of this limited information.  There could be a problem.  Maybe there isn't, or it's a problem under circumstances which won't normally arise.  For instance his assertion that the H1N has low handling noise by comparison is nonsense- the H1N is notorious for handling noise.  In fact, when it comes down to it, all these small devices suffer from it as it's just about impossible to decouple the small, llight capsules from the body.

If you watch the video there is no denying that these recorders produce so much interference that they are unusable "in his use case" which looks to be his home.

Don't know why you have so much beef with that dude but based on his video alone I wouldn't buy one of these.

M4 has interesting potential for a super simple 4-channel mic-array consisting of a spaced-pair + coincident-center-pair, which in my experience is the most useful 4-channel microphone array for tapers. 

I'd love to see someone plug two rigid extension tube podium-style microphones (the kind with a rigid section ~25 to 50cm or so long with XLR at one end and short gooseneck with microphone at the other end) directly into the XLRs on opposite sides and mount the entire thing on a clamp or stand, eliminating mic-bar and wiring.  The mics need to be light enough that the latching XLR connection can support them, but seems reasonable to me.  May want  to use a section of coat-hanger wire to connect the two and reduce strain on the XLRs with wider spreads.

Visual aid below.  In place of mic-cables, plug in two rigid-extension-tube podium mics.

There's some very interesting moments in this video about the M3 - it's the first time I've heard a viable voice recording made 100 feet away from the speaker!  The end-user reviewer has had no problems with RF breakthrough, by the way.

https://youtu.be/_ZChtqgCit8

I think I won't be able to avoid the temptation any longer - if only to graduate from my first portable valve-equipped recorder with 7 minutes battery life (60 years ago??!), to a 32 bit float digital recorder with a good quality MS mic built in.  Wow, things have changed...

RF interference has been confirmed by Zoom and a batch of M3 devices has been recalled.  If the last 4 digits of the serial number are in the range 0302 - 1096, you can request a free replacement.  It seems that this was caused by an assembly problem during early production.  Stuff happens - personally I wouldn't let this put me off buying the product now.  I'm still waiting for my pre-order to arrive.

Units of the M2 and M4 are also affected but I don't have the serial numbers to hand right now.

At last my Zoom M3 has arrived.  First impressions -

- It feels very light and has an air about it of something which should be treated with care.  But mics should always be treated with care.  As for lightness, this is a plus point in the video sphere.  When doing video I might well mount it on my camera gimbal, and in that context, lightness and balance is very important.

- It is heavier than my Sennheiser stereo video mic but that only has one AA battery.

- The dead cat for the Sennheiser fits onto the Zoom, just about, and that will save me a few dollars.

- Changing the battery of the Zoom will be awkward when it is mounted on its suspension clip, but I'll probably not keep taking it on and off the clip for fear of stressing it.

- The mic can't be fitted to the clip upside down, for dangling above musicians.  That means I would have to reverse left and right when editing but I guess that's no big deal.

- It's weird to have a recorder with no metering and no time display.  But in the context of this device, meters and displays really are not required.  There are buttons to set stereo width (it records a left right file and an MS undecoded file at the same time) and low cut, and these do have tiny but bright LED indicators.  Likewise the power and record buttons are well lit. 

- If the record button is held down to start recording, the system is in lock mode.  To stop recording, long press the record button again.

- There's a simple but not-obvious routine to format the memory card but the case is marked to show the method.

- Only the most recent file can be played.  This is perhaps the biggest issue for me (but I knew about it in advance).  And I don't think there's a fast forward or back method.  But I think a whole new approach is required with this device in my world of recording acoustic (classical mostly) music.  Instead of turning up for a concert an hour before rehearsal time, setting up mics, cabling back to the control room while somehow avoiding tripping hazards, setting up the recorder and monitoring system and so on, with this device it would be perfectly possible to arrive five minutes early, plonk down a stand with the mic on top, press record, and come back from the nearest bar when the concert is finished.

Anyway, next step is to actually record something with it.  Right now I don't have any music gigs lined up but I might just do some initial tests using my Tannoy speakers as a source in my 'studio' and comparing with other well known devices.   I am hoping that Zoom have designed this with the 32 bit float recorder being matched with a reasonable preamp (dual in fact) and with mic capsules that don't let the back end down - leading to an integrated whole that performs perhaps better than could be expected from individual components to the same value.  Otherwise, the point is lost.  I will check for obvious signs of RF interference but given that the initial batch were withdrawn and replaced, and it's been some months off the market while the problems were sorted, I would be very surprised if they had still got that wrong.

Briefly, I've done some very quick tests in front of the Tannoys.  Results are encouraging.  Looking at the spectral display in Audition, I can't see anything amiss in terms of whistles at set frequencies.  Noise level is low (well, in practical terms I can't hear any but my ears are old...). 

The thing that made me really sit up was the very high level available in the cans (DT100) for monitoring and playback.  Monitoring is present as soon as you turn it on (there's no record pause button).  But I have a tiny suspicion that there may be some kind of limiter at work on the headphone output.  When replayed direct from the memory card, I don't hear anything of the kind. 

Frequency response - well, in such a crude test it's going to be messed up by the room acoustics.  But the top end is very clear and punchy.  Bottom end seems fine but I haven't yet tested that with a really revealing track.  Stereo image is very well defined indeed (when set to 120 degrees).  Recording between the speakers, then putting it right up against one of them to cause it to "overload', causes no problems when normalised, as you'd expect from 32 bit float.

More crude tests to follow (including testing against the H2N with is the other recorder I have that I would describe as "a mic that records") but I really do need to try it on actual live acoustic music.  And maybe some traffic noise for the bottom end!

Something I've noticed on samples on YouTube, and now confirmed with my M3, is that the stereo image at the rear gets inverted - speaking towards the mic from the rear left actually plays back on the rear right, etc.  But I think I read somewhere that this is a known consequence of MS mic techniques.  Maybe it's more pronounced because the centre mic is a shotgun type.  At the dead centre at the back, there's a distinct reduction in signal but that could be useful in many situations.  I've heard a shotgun-based MS recording from the rear of a hall, up in the gallery, and the stereo image and apparent closeness of the recording was beyond expectation.

First test- a domestic recording showing spectral analysis display set to show a 140dB range to ensure nothing untoward is lurking in the noise, and later I've shown frequency response and phase.  Looks good to me.  Beware, it gets loud.  But even though I recorded a spinning washing machinie with a tumble drier on top of it close up, it still needed +12dB approx of normalisation, so Zoom have clearly configured it to only need post processing gain reduction if the incoming audio was really loud.

https://youtu.be/zNzRcAY13FE

I don't know how badly YouTube mangles the original audio, but obviously the display shown comes from the original audio flle, unprocessed apart from normalising.

Monitoring is present as soon as you turn it on (there's no record pause button).

Zoom F8 is the same with regard to monitoring.  Effectively in rec/pause as soon as turned on, although you can pause after you start recording.  Presumably other current Zoom recorders work similarly.

Something I've noticed on samples on YouTube, and now confirmed with my M3, is that the stereo image at the rear gets inverted - speaking towards the mic from the rear left actually plays back on the rear right, etc.  But I think I read somewhere that this is a known consequence of MS mic techniques.  Maybe it's more pronounced because the centre mic is a shotgun type.  At the dead centre at the back, there's a distinct reduction in signal but that could be useful in many situations.

The rear image flip you describe is a consequence of the polar pattern of the microphones used in X/Y, and of the polar pattern of the Mid microphone in M/S in combination with the Mid/Side ratio used.  The classic example of this is Blumlein configuration crossed fig-8's, and the result is the same if set up in the classic manner as X/Y, or as M/S.  With a Blumlein stereo pair, all sound sources located behind the microphone position will be picked up with the same sensitivity as everything in front, but upon playback the positional imaging of everything in back will be flipped Right/Left in comparison to everything in front.  Substituting supercard/hypercardioids that have a less sensitive "rear-lobe" than fig-8's, the same image flipping occurs for sources in back, but they will be picked up with reduced sensitivity.  With Mid/Side using a cardioid Mid and a 50/50 M/S ratio, the decoded output will be similar to X/Y using supercardioids.  Substituting a supercardioid Mid the output will be similar to X/Y hypercardioids. 

I don't know the pickup pattern of the capsule Zoom is using in the shotgun Mid here, but I presume its a supercardioid or cardioid. Its the interference tube that defines it as being a shotgun rather than the polar pattern of the capsule behind the interference tube, but typically something supercard-ish is used as that pattern minimizes sensitivity for everything off-axis more than any other pattern and thus provides the best starting point for creating a maximally exclusive "shotgun" design.

Wow, thanks for that tech explanation.  I have used MS mics as the basis of all my serious recordings since 1984 but I remain slightly hazy about the underlying theory!  My go-to pair for classical recording was a Sennheiser MKH 30 and 40 (if I recall the models correctly), and that rear image reversal phenomenon was never very apparent, but of course when recording classical musicians in front, and the room reverb behind, there wasn't much to reveal any such problem.  Now, with the Zoom mic that weighs a few grams and is thus easy to hand hold and speak into at odd angles, the issue is more manifest (and as you explain, the capsules used would be relevant).

It grieves me that these days I have almost no chance of recording anything, let alone a classical performance in a good acoustic, but I am hopeful that before the end of the year I will be able to get some opportunities to discover whether the M3 is a breakthrough or a disaster!  Probably somewhere in between.

The good news is that someone has tried the M3 for recording an orchestra with violin soloist.  The bad news is that he placed the mic somewhere towards the back of the hall, and afterwards applied compression and / or limiting, eq, and heaven knows what else.  So I'm not sure it's the test I was hoping to see (and, of course, hear).  (Also the violin soloist seems to be having some issues but it looks like it was a rehearsal and maybe she wasn't warmed up, to be fair).

https://youtu.be/qLEMRTx8n5M?si=541vZs85EciiUyQ2&t=1489

Perhaps more impressive when it comes to a demonstration of dynamic range is this video where the reviewer plays his trumpet straight into it at a variety of dynamics.  This does seem to show that not only is the 32 bit float recorder section doing what it should, but also the capsules and preamps seem comfortable with the considerable dynamic range.

https://youtu.be/qanMWDrx0wM?si=nNEDelbFLlU9Xibj

Sadly my present circumstances do not allow me to get out and do my own tests, but one day that will happen (otherwise, why did I buy the mic?!)

Sorry, Colin, I misread M2 for M3.

But... I really am tempted to add the M2 to my collection of grossly underused recording devices.  Here in AU it's going for around half recommended price for the next few days, and I can't resist a bargain.  But looking through the manual of it, there seems to be much more to it than meets the eye.  There's onboard normalisation after recording if desired, and export to other bit depths onboard too.  And it can be used as a 32 bit float USB-C mic too (or 24 bit).  Much of the functionality seems based on the Zoom F3 except you don't get to choose the source - it's the inbuilt mics in stereo or mono, and that's it.  But Zoom have a serious amount of experience with small inexpensive mic capsules, and there would be no point at all in building a 32 bit float device with totally crap mics, so...  OF course it's far from a stealth device, proclaming itself to be a recording mic as loud as it can, but in my uses that's not a problem.

Sure.  A coincident pair in the center, in this case the internal mics of the recorder, works very nicely between either omnis or a directional pair (or both).  Choice of which mostly depends on the room, the acoustics, how far back the recording position.   Generally a pair of omnis are best spaced wider (something 3' apart minimum is good), where as a near-spaced directional pair needn't be spaced as far (something like 2' apart is good) if angled +/- 45 degrees apart.

I mostly use DPA 4098H supercards for this in my arrays, which are choir mics intended for hanging, similar to 4099.

If using both omnis and near-spaced directionals on either side of a coincident center pair (recording 6 channels), space the directional pair 2' apart angled +/- 45 degrees and  increase the minimum spacing of the omnis to 4'. 

In either case, 5' or 6' between omnis is usually better than the minimum spacing I suggest above.

Here is my first test of the Zoom M2 Mictrak.  It is simply a recording of the silence in my suburban garden after midnight, massively amplified by normalising.  There was some very light rain on the garden umbrella, barely audible out there at the time, but on this recording it's now really loud.  Far away you can hear the rumble of a distant motorway.  At the end there's a short recording of me speaking quietly in the same environment on a separately normalised file, to give some idea of how quiet it really was.

My elderly ears can't hear any system noise at all, despite the massive digital gain.  But maybe yours can?  Anyway, I am hugely impressed with this odd looking device - especially at half price!  Sadly, the first batch produced had a fault which caused RF breakthrough to spoil the sound, and its reputation was badly damaged.  Subsequent production runs (after that one was withdrawn and money refunded) seem fine.  Certainly I couldn't hear anything amiss.  I'll be doing a few more tests in the next couple of days, I hope, and will post the links here in due course.

[Edit - I just checked and the price I paid was about the typical price of a Zoom H1N.  I mean, I can't complain, can I?!]

Today I made a very quick video which included some testing of the M2.  The supplied wind muff does help with wind noise but it really needs something more effective out of doors.  Of course for recording music indoors, that's less of a problem (apart from strong air conditioning in a hall!).  Right at the end I included a spur of the moment recording of a dog barking at me as I passed its garden gate.  It's a quite good demo of what 32 bit float is all about.

I just checked the F3 user manual and that device seems to lack some of the neat features of the M2 - perhaps the M2 is aimed at a more amateur market which needs help!  In particular, the ability to export in 24 or 16 bits, to create a normalised copy internally, and to play back at a normalised replay level (which is really, really handy).

And here's another one showing the Zoom M2 being used as a USB-C mic connected to the Pocket 3 camera.  In this mode it has some handy features such as changeable output level, mute button, replay via headphones of what has been recorded on the external device, and choice of 24 bit or 32 bit float output to the recorder.  Sadly the latter can't be recorded by the Pocket 3.  But I wonder whether the F3 accepts USB-C mics with 32 bit float output?  A 32 bit float USB-C mic at this price point has to be pretty rare.

On Christmas Day the weather forcast warns me that we will have the most severe thunderstorms for many years.  Oh great.  Well, nevermind - I will take the M2 with me to the family party and see if I can record some good 32 bit float low frequency test material while I chomp on the turkey.   ;D

According to Zoom these devices should share the F series preamps, which should be good thing.

The functionality of the M4 is interesting to me as it offers both XLR and mini-jack input and perhaps even passable build-in mics(?). The missing mini-jack stereo input of the F3 makes it a no-go for me.
However, the design layout of the M4 is not my cup of tea, to say the least, but I will set up some price alerts should a lower price make this device more appealing.
Roland R-07 -> FEL Communications Clippy EM172 Omnis or pair of RØDE Lavaliers.
iPhone 14 -> Shure MV88 or Sennheiser AMBEO Smart Headset

I just came across this video where the sound comes from the Zoom M3 Mictrak device (it says).  If nothing else it's an ideal test of 32 bit float, as the location sound gets pretty loud aqnd peaky and personally it's the kind of unpredicatable scenario where level setting is best avoided.  I'd suggest watching the last five minutes or so to evaluate the sound - or of course watch the whole thing if interested!  It certainly seems to have no trouble with the high frequencies and the stereo image is good and wide.  The drums in use seem to be relatively small so the amount of LF on offer may have been a bit too modest to really test that aspect.
