Why a Ribbon Mic, and Why This One?
I was interested in checking out ribbon mic because I wanted something with a smoother top end. I find that the top end of condensers (even my workhorse AT3035, which I love) can sometimes get a bit harsh.

Being able to get a smooth top end is great for many recording situations, of course, but in my case at least, it's important to be able to get this straight from the mic (i.e., not via EQ in post-production) because I spend most of my saxophone practice time (>95%) in my WhisperRoom, playing into a mic and monitoring via headphones.

Many ribbon mics have a substantial rolloff of the top frequencies, which can make them sound stuffy or tubby, IMO. I was interested in finding an affordable ribbon mic with a relatively flat frequency response that would smooth the top end without sounding like I'd stuffed a towel in the bell. The two that kept popping up in my searches were this one (the NoHype LRM-2b) and the SE Voodoo VR1. I went with the NoHype because it was substantially cheaper and had a lot of word-of-mouth praise online.

103262


Price: €190 (about $226 USD)
  • Note: This price above is for the version with the stock transformer, which is what I ordered (you can optionally order it with a Lundahl transformer for an additional €100).
  • Note: If you plan on using this mic with a Fethead, you should order it from NoHype at the same time, since it's cheaper than buying it from online retailers. E.g., €55 (about $65) from NoHype vs. $90 from Amazon.
About the Mic
The mic is pretty lightweight and compact for a ribbon. Not as compact as the Voodoo VR1 or Royer r121, but its weight and size are comparable to my AT3035 LDC.

I haven't formally measured the frequency response of this mic myself, but the frequency response curve provided by the manufacturer shows it to have a very flat response for a ribbon mic, and it sounds pretty flat to me.

103263


Edit (11/12/2021):
I finally got my hands on a calibrated measurement mic and measured the frequency response myself. My measurements appear in the plot below. As you can see, it agrees broadly with the manufacturer's curve: a relatively flat response for a ribbon mic, but with a significant ( ~10 dB) boost below 50 Hz. All the comments below still apply.

Image


It has a smooth top end, but without any tubbiness or stuffiness. However, as indicated in the frequency response curve, it has a significant boost in sensitivity at low end, this boost is at frequencies too low to matter for saxes (at least S/A/T), but it means that you have to be careful about mechanical transmission of vibrations (i.e., this mic must be used with a suspension mount).

Speaking of which:

I don't like the included suspension mount. This is probably the only feature of this mic that I don't like. The suspension band tension is pretty slack (and can't be adjusted without cutting and shortening the band), the pivot joint is difficult to tighten securely so that it doesn't move, and unless the mic is mounted plumb vertical, the fact that the included suspension mount attaches to the very end of the mic exacerbates both of these problems (due to the cantilevering of the mic).
  • I replaced the included suspension mount with this one, which works much better for me.
103265


Used with a Fethead inline preamp (which adds about 27db of gain), sensitivity is about 5 db greater than the AT3035. Using it with the Fethead on my MOTU M4 and recording from 2-3 feet away, I have to set the gain dial at about 8 o'clock (around 17%) to prevent clipping.

  • The MOTU's preamps provide a maximum of 60dB of gain, which is pretty standard for consumer-level audio interfaces. This means that you shouldn't need an external preamp when using this mic to record saxes.
I nonetheless use it with a Fethead for two reasons:

  1. Phantom protection. I often use this with an Helicon voice reverb pedal that has always-on phantom power. It's also just good not to have to worry about plugging it into a phantom-powered input.
  2. To prevent the audio interface preamps from coloring the frequency response of the LRM-2b. I'm not yet sure whether this is a problem for my MOTU M4, whose preamps have about 2kΩ input impedance, but it's definitely not a problem with the Fethead whose input impedance is an order of magnitude larger (22kΩ).
Edit (4/18/2021):

I finally got around to measuring the frequency-impedance function (I used the voltage-drop method, with 100 frequencies sampled along a log grid).

Here's the result:

103632


One thing worth noting is that, across all measured frequencies, the microphone's output impedance is higher than the nominal impedance of 250Ω claimed by the manufacturer. I point this out for completeness. It shouldn't be a concern unless you plan to use this mic with really long cable runs.

Of course, the reason for measuring this function in the first place was to determine how the relatively low input impedance of standard consumer audio interface preamps might color the mic's response (by attenuating the signal via loading). So I computed the expected attenuation for a typical (2kΩ) audio interface preamp below (blue curve):

103633


I've also included the attenuation function for the Fethead (gray curve). My conclusion is that using an audio interface preamp will color the sound, but that the effect will be very subtle (note that the maximum difference in attenuation across frequencies is only about 1.5 dB, which should be just barely perceptible).

The Recording Path
  • AT3035 (with 10dB pad and low cut both switched off) is plugged directly into one of the two MOTU M4 audio interface preamp.
  • NoHype LRM-2b is plugged into Fethead, then into the other MOTU M4 audio interface preamp.
  • The mics were mounted on a stereo bar about 3.5 inches apart (center-to-center), positioned about 2.5-3 feet away from the saxophone, about a foot above the bell, and aimed toward the middle of the horn.
  • The MOTU M4 has lcd level meters on the front, and I used these meters to set the inputs equal to each other. I didn't modify the input levels in the DAW (Reaper) itself.
Sample Recordings
To provide a sense of the NoHype's sound, I made simultaneous recordings on it and on my usual standard LDC mic, the Audio Technica AT3035.

I've included eight sample clips recorded on alto saxophone. I'll amend this post in the future to include more instruments and samples, depending on what readers want to hear. I started with the alto samples (though I'm primarily a tenor player) because it's on alto that the harshness of the condensers most often bothers me.

The eight clips include two different styles-ballad vs. fast blues- and two processing treatments-dry (no effects) vs. wet (with a small amount of reverb) on each of the two microphones.

To use examples that are natural-sounding but repeatable, I'm sticking to solo transcriptions/excerpts. The "fast blues" example is a Bird solo from Now's The Time, while the "ballad" example is Karolina Strassmayer's solo on the melody of If You Could See Me Now from this WDR Big Band recording.

I like the recorded sounds of both mics. They are obviously different, but each has its strengths. However, for monitoring while practicing, I find the smoothness of the LRM-2b much more pleasant and less tiring.

Listen to the clips below and let me know what you think of the LRM-2b.

Great review and shootout, thank you so very much for doing this! You're getting very good sounds out of both (and out of your instrument, hey, the most important part!). I'm surprised how noticeable the difference in the high-end is between the two mics, although maybe I shouldn't be. The AT is noticeably brighter, and threatens sibilance, although you still sound quite nice on it. It's a solid unassuming little mic, that's for sure.

For alto in particular, though, the LRM is really appropriate. It tames the high end in a very classy way and has plenty of body. It sounds very clean and clear, not overly "characterful" but also not boring. I'm impressed. JP Gerard is a damn genius, I think you've finally helped me to make up my mind to just buy one from him already.

Now I'm curious how the LRM2B compares to the LRMV on alto! I'm leaning toward the LRMV since I love the old RCA 77 and 44 mics, and it's modeled loosely in that direction. It would also be a big contrast to my LDC workhorse (u87), which is what I want – but from hearing your clips here, the LRM2B would be as well. I love the mellow high end it's getting!

A good long ribbon mic is a beautiful thing. Thank you for putting so much time and thought into this, very very well done.

Yeah, the AT3035 was a bit tamer than it usually is on alto. I think that's because I was back a bit further from the mic than I usually am. I normally play around 1-1.5 feet away from the mic, which makes the alto sound a bit harsher on the AT mic. For this recording, I stepped back about 3 feet. That's because the LRM-2b, like many other ribbon mics, has a noticeable proximity effect. I wanted to avoid this in order to compare the two mics on equal footing. The AT sounds better farther back, but the tradeoff is that you get more of the room sound (which in a small room like my WhisperRoom means more boominess).

The funny thing is that, for alto at least, distance seems to have nearly opposite effects on the frequency response of the two mics. Because of the strong proximity effect of the LRM-2b, the high-end mellows as you get in close, whereas for the AT, which has a negligible proximity effect, the high-end gets harsher as you move in.

Thanks, and good luck with your decision!

I think both mics sound very good and my preference between them switched depending on which pair of headphones I was using between my Sony MDR-7506 and Audio Technica ATH-M50x. On the 7506, I preferred the ribbon mic for how it smoothed out some of the high end harshness, but on the M50X, the bit of extra high end in the condenser didn't sound harsh at all. I have always used the 7506 for recording, but have preferred the AT for listening lately, just for the more forgiving high end, so that more or less lines up with what I'd expect.

Both sound quite good, though!
I'm monitoring and listening through M50x's as well, but I notice a slightly different effect. For me, the AT sounds a bit harsher when I'm monitoring live (while playing) then when I later play back the recordings. It could be something about the combination of the sound produced by the headphones and the leak of direct sound from the room (though it seems that combination should emphasize lower frequencies), or it could be sensitization to high-end over long playing/practice sessions that doesn't manifest over shorter listening periods.

GREAT PLAYING. Both mics work, and have an even sound...nothing jumps out. I liked the AT 3035 better, because I could hear the highs, but they sounded just right, a good balance, and it sounds more natural to my ear. When I built my studio, I bought a RODE tube mic, and ran it through a ART pre-amp that I had modified that had 12 AX7 tubes in it. I replaced the tubes with some vintage 1966 Mullard tubes, and I could dial in how much tube warmth I want. The tubes added warmth to it, and kept it from getting strident like a all solid state pre-amp can sometimes be.

I also replaced the stock Russian tube in the mic with a new old stock , 1966 Telefunken tube that cost me $250. That made a huge difference, and it really gave it a smooth sound. Disclaimer: I am 72, love tubes and analog for that warmth, so consider me old school. A good tube in a condenser mic and/or pre-amp and compressor adds warmth, and seems to keep things from getting too strident. May I compliment you again on your playing...it sounds like a jazz sax solo should sound, relaxed and natural. Keep doing what you are doing.
Thanks!

MMichel, what was your delivery time from ordering?
It took 10 days, but most of that time was spent sitting in customs, waiting for the USPS to pick it up. JP shipped it out almost immediately.

And does the included shock mount physically connect to the mic? Like with a screw base? It's hard to tell from the pictures and description. I might have to pick up a pair of these, as I need a pair of decent ribbons....
Yes, the included shock mount has a threaded adapter that screws onto the base of the LRM-2b. If you wind up ordering a pair, JP will stereo match them for you at no extra cost (though you do have to request this).

That's because the 7506s have an almost nasty high end boost. Makes them good for cuing headphones on live gigs at FOH or monitor world (i.e. they can cut through the mix and crowd noise to let you know if there's a problem with a channel you are cuing). But I have long since moved past them for recording monitoring. I do prefer the M50Xs for recording monitoring as they are more natural.

Also, did you get the regular transformer version? Or the Lundahl transformer?

For those interested, I finally got around to measuring the microphone's frequency-impedance function. I've amended my review to include a plot of this function, as well as a plot of its expected effect on coloration when the mic is used with a relatively low-impedance preamp.

I just ordered a NoHype LRM-V and I'll post my own findings when it shows up! I can't promise that my review will be nearly as detailed, in-depth, or helpful as mmichel's review of the LRM2B... in fact, I can promise it won't be... but I look forward to taking it for a spin nonetheless. I plan to pair it with my u87, my hunch is they'll work well together.
 
#10 ·
My NoHype LRM-V showed up and I got to use it for a professional session yesterday, paired with my u87... and it's fantastic. I'll put up clips sometime soon after I get a chance to do some stuff just for fun. But the Neumann and the NoHype paired together are resulting in my favorite recorded sound that I think I've ever gotten.
 
#13 ·
Well, I finally got my hands on a calibrated measurement microphone and measured the frequency response of the NoHype LRM-2b myself. Here are the results:

Image


This agrees broadly with the manufacturer's response plot of a relatively flat curve with a significant boost below about 50 Hz. It also suggests that these mics (whose ribbon motors are hand-assembled in a small shop) are pretty consistent. I've updated the review above with this new information.
 
#14 ·
Cool! Thanks for doing that. The 2B definitely measures as more linear in the HF than the V, which correlates with what I hear in recordings. I'd wager the 2B would be a more useful "all-rounder" while the V is better in specific niche applications. I reckon I might just get a 2B sometime in the next few months, it's just a great-sounding mic for next to no money.

For what it's worth, my absolute favorite application of my LRMV so far? Recording tambourine and shaker! (Which I do surprisingly often... on my own stuff as well as production and soundtrack work.) Normally I have to roll off a substantial amount of HF when tracking those instruments, but with the LRMV I just track them straight in and they're good to go with basically no processing. The V tames the highs while somehow providing a really great "crunch" to the sound which juuuust rules.

Thanks for the great review!

It's always interesting to hear about ribbons with extended high frequency response.

Also very interesting was the effect of input impedance on the high end.

If you made your frequency response measurement figure a vector pdf or a png with a transparent background, you could overlay it on the manufacturer's plot. I actually tried to make the background transparent, but wasn't successful in a few minutes of trying (using ImageMagick convert). I would be happy to overlay it if you repost one with a transparent background (vector pdf is best).

Another great ribbon for saxes (I have not tried it myself) is the Beyer M160. A bit pricier, though. The recordings of saxophones I have heard from it sound very natural, maybe with a slight "fuzzy" quality. It has an extended high frequency response, but the ribbon material may not last, according to reviews. There are people who rebuild them with better materials.

Also, some condensers I think have the quality you are looking for: Neumann TLM-102, TLM-103, TLM-170; MXL Genesis Tube; many others, especially more expensive. The Neumanns tend to sound smooth, but extended.

None of my suggestions fit this price range, unfortunately. However, the Octava MK-319 (typically $150 used) has this quality.

I believe the AT3035 has a smaller diaphragm and it may sound grittier than larger diaphragms. I used to have a pair, but they sounded "roomy", which is not an issue in your room. They do have a flat frequency response.

...and also the dynamic EV RE-20.

I wasn't really trying to compare them in detail, or I would have used a plot digitizer to pull the data directly from the manufacturer's plot (e.g., as a scientist, I use this program frequently to pull data from old papers).

However, I've attached a transparent .png of the plot in case you're really interested. I also made an .svg, but the forum software won't let me attach it.

It's possible, though I haven't noticed it. In any event, the AT3035 does indeed have a 19mm (~3/4") diaphragm, which is midway between the popular thresholds for delimiting SDC vs. LDC mics. However, I'm pretty satisfied with these mics. Both are real bargains at their going prices.

There is a very slight (<1 degree) rotation of the manufacturer's plot. So the minor ticks look different on the left vs. the right side. I tried to rotate it straight, but it was fussy, so at this level, here we are. Here is the plot without normalization (all I did was shift your plot back down so the major ticks nearly line up):

Image


I just noticed the x-axis ticks are off, and there is no way to make them line up by stretching either plot. This is very strange -- the manufacturer's plot does not have the correct log spacing in frequency, or the one you provided doesn't...

Interesting article. Maybe I'll read it to broaden my horizons...I've used plot digitizing tools also in the past -- involves some labor, but sometimes the only choice.
