The RSM-4 delivers uncompromised ribbon mic sound.

The Nady RSM-4 is a ribbon microphone with a versatile design that makes it ideal for numerous applications, from close-miking guitar cabs to vocal recording and live use. The RSM-4 mic's unique compact ring shape allows simple, unobtrusive placement anywhere.
The Nady RSM-4 microphone's low-tension, 45mm long, 6-micron thick aluminum ribbon design has a typical large, mellow reproduction with smooth, natural response across the spectrum. Fast, accurate transient response, ultrahigh 165dB SPL capability, and overall stunning realism.

The figure-8 pickup pattern offers extended sweet spots and increased off-axis high frequency reponse on the sides with decreased high response above and below on-axis (though with lower audio levels). Individual recording volume control of separate sources is enabled through the use of stereo mic setups where isolation is achieved by placing the source so that it is in the principal axis of one mic and the off-axis null of the other.

The RSM-4 has a machined housing with advanced internal shockmount construction for rugged reliability and includes a mic clip and zippered pouch.

RSM - 4

By Anonymous

from Undisclosed

This mic is very smooth and articulate at the same time. I played it through a PreSonus blue tube mic-pre and an art compressor, just outstanding.Sounds incredible with a shure 57 mixed in.Highly recommended!

No good for vocals, alright for instruments

By Bmattingly

from Indiana

I've used this mic quite a few times now and have always noticed the same problems. -As a previous reviewer mentioned, it's a noisy mic and you're gonna need a lot of gain for quiet instruments (Quiet like, acoustic guitar quiet). Not a great combo-While the mic is great for instruments (amp cabinets and trumpets, in my case), I always get an excessively nasal response on all vocal takes. It was so bad that I actually got a better sound out of a crappy Chinese dynamic mic than this. I also tried the same song on a Zoom H2. Both times there was almost no nasal sound (what little there was is my own technique's fault.)In spite of all this, it's not a horrible mic. Bottom line is don't use it on vocals or quiet instruments, but if you need good response on something already loud, go for it.


This one surprised me

By Drew-1y1jA

from Boston, MA

I grabbed a Nady RS-4 on a whim - I didn't own a figure 8 mic, I'd always been curious to check out a ribbon, and for what this mic sells for (comparable to a SM57), it seemed like a no brainer. Much to my surprise, while this isn't a very "transparent" microphone (the highs are, while still musical, a touch rounded, and the bass isn't overly pronounced), it actually works REALLY well with a bright, aggressive amp like my Mesa Rectoverb for capturing lead guitar. It has a wider sweet spot than my go-to SM57, so it sounds less "filtered" and isn't as position sensitive. A better shockmount and some sort of proper storage case (come on, we all know how delicate ribbons are) would be nice, but strictly on tone this is a surprising "dark horse" contender for recording guitars. I'm impressed.

I got a call from the local music shop that this sweet little mic was in stock and I ought to check it out. I've been wanting a ribbon mic for a while now but didn't want to go broke finding out that it didn't provide any added benefit. The price on this Nady was just right for experimenting and was I not disappointed. I found it to work well with vocals after using to redo some vocals on a song I have not been pleased with. I would describe this mic as being a balanced combination between a condensor and tube mic giving the quality a smooth range between crisp highs and warm lows. A great buy!

Get this mic!!

By Lollygagger

from Indiana

Ok Stock, these are hit or miss. You could get one with a properlly tensioned ribbon, or one that's loose and bnags against the grill. They sound pretty good out of the box, but if you change out the transformer with a Edcor, or a Lundhal...these mics sound ungodly good!!!! For as cheap as they two or three. I have four (all modded) two on the drum set sound amazing. I use the others on electric guitar...and woooweee do they sound good.

Had not used ribbons in 20 years or so. Rsm 4 going head to head with Neumann something, in the lab. jazzy tubey tone, makes the vocals come off like Nat Cole, Sinatra, Sam Cooke. mic to Avalon front end, Straight to Protools LE. I bought 2 from a local dealer to try out stereo miking on BGVs. Saved lots of money on this one. After these sessions on to guitar cabs and drum room work. Delicate, Careful, NO Phantom Power!!!


Great for vocals, harp, etc

By AROtotheN

from Ypsilanti, MI USA

The RMS-4 is my first ever ribbon mic. It sounds absolutely fabulous on my voice, and on harmonica, guitar cabs, etc. Found it to be a bit boomy when mic'ing up my acoustic, but this my be due to my inexperience.Opened it up and noticed the ribbon to be quite slack, so I tensioned it up myself. Almost tore the ribbon, PheW!!! but didn't. Now it sounds better than when it came.


Ignore the negative reports.. amazing mic

By Gerrald Samraj

from New york

The previous reports say that it was noisy and needs more gain... Maybe they forgot its a ribbon for christ's sake... Its been an amazing experience recording the horn sections with the Nady... Besides... You cant beat a deal like this... Its the best quality you can get at this price... Value for its money indeed


Nice 2nd ribbon...

By That70'sGuy

from Midwest

See all my reviews

Added this to my mic cabinet as a 2nd type of ribbon and wasn't disappointed! Great deal under a "C" note! Slightly darker than my other ribbon mic, perhaps the 6 micron vs. the 2 micron ribbon thickness and shorter lenght accounts for that, but very natural, smooth responce. For the money you absolutely can't go worng here!



By SolaceMediaGroup

from New York, NY

I first plugged into my PC Soundcard with an adapter, and it seemed very low and grainy. I almost lost hope beofre I plugged this bad boy up to a digi003 inteface/preamp. Wow! There were several other EXPENSIVE mics in the studio that we compared the RSM to. None of them compared to its full ich, warm sound. This is definitely an excellent buy for vocals, never tried instruments. Vocals barely need any processing.


wow this it

By Patrick Mildenberg

from Bogota ,Colombia

a couple months ago i bought a couple of these little marvels,i thouht for the price what the heck nothing to loose but what a surprise, ive got from them. I own several different ribon mics including RCA and Beyer as well as Oktava,but i had never heard a trumpet sound so good until i tried the rsm 4 its a shame that this mics (the whole RSM line)were not awarded a tech or em award these are trully amazing for the price


Excellent for the price

By Jordan Freshour

Honestly, I hate Nady. Probably about the most budget-quality of any audio equipment manufacturer around. Everything I have ever heard or have used from them has been terrible. Except...

I purchased this microphone about a year and a half ago to augment my small collection of microphones for my home studio. I did not have a ribbon mic and wanted to add one, so for the price I figured it would be a good idea. At first, I thought it was terribly noisy and didn't use it on a recording until I discovered it was actually just a bad channel in my snake. Upon realizing this, I used it on a dumbeck and djembe... I really had no expectations, but the results were very pleasant. I was able to capture a fantastic sound - warm, punchy and true to the source. The drum tracks fit excpetionally well in the mix.. I used compression (of course!), but no equalisation was needed. I've not tried it (so far) on any other instruments, but this will be my go-to microphone for hand drums in the future.

It looks like Nady has found their niche, as I have heard/read mostly positive reviews of their ribbon mics overall. Highly recommend.

It is worth noting that I've zapped this thing with phantom power several times, with no damage done... very thankful that it's been designed to take this unintentional abuse.


decent budget ribbon mic

By Steely Don

from Silver Spring, MD (Washington, D.C. area)

I own two, and plan on getting eight more!They're fine for non-critical live use as drum overheads, backing vocals or electric guitar in a home studio. for other applications, use a Royer, especially their stereo model, if you can afford one or two.


My first ribbon

By Jon Sims

from Dallas Texas

See all my reviews

This mic is all they said it would be. It is smoooooth and the most natural sounding mic ive heard. Great for elecky guitar cabs. Sounds like what you put in front of it. Vocals wow! use a pop filter. I think everyone should have one. My O2R onboard pres drive this thing good and it is dead quiet. I would love to get another to use for overheads or room mics.



By Spasticcat

from MN

First of all, the mic clip that comes with this is far too small - it doesn't come close to fitting around this mic or even an sm57. So plan on ordering a bigger mic clip with it if you'll need one. Mine was also in the package upside-down. Which is not a great idea since this is a ribbon mic. The sound quality is decent. Smooth, warm, bassy. Not very detailed on the high-end and it's a pretty noisy microphone. I have to run a low-pass filter on this mic at all times to keep the hiss out of the track. Also, you'll really need to add a lot of gain to this mic to get a sound out of it.On that same note, it seems to be working well on drums and other LOUD sources, but not so well on quiet things like banjo and singing.A good value if you just want a cheap figure 8 / ribbon mic to experiment with and see what it can do, just don't expect super-outstanding sound quality.


Pretty Good For The Money.

Nady RSM-4 Ribbon Studio Microphone: I bought one of these from Musician's Friend to try out. I'm well experienced with this stuff and have built my own mic pre's for years. I experienced none of the problems that a few of the other reviewers mentioned. The mic I have works great. I will tell you a secret about these and about ribbon mics in general: If you find the sound a bit too dull, just turn the mic around, and record from the other side. Voila! More treble! This is what a very expensive ribbon mike manufacturer does without telling anyone. All in all a great deal for the money.


Not Bad for vocals

By Tom-tr607

from Mundelein, IL

I thought this mic could use a review by someone who is used to using a pretty wide variety of microphones, including high-priced mics like the Neumanns. I purchased this mic on a bit of a whim, mostly because it is a ribbon mic. I have much more expensive mics, but it's always nice to have a good variety of mics around, because sometimes somebody's voice will sound 10x better on one mic than anotherThis mic does a decent job on vocals. The low end is more pronounced than with most condenser microphones, and the high end is much much less brittle sounding than you get with a condenser. So overall, it has the characteristics that you'd expect from a ribbon microphone. There is also a subtle saturation distortion that sounds almost like it's being run through a tube preamp...not great for voiceover recording, where clarity is key, but actually pretty nice for singing. I think the frequency response is a little biased toward the low end, so I'll likely EQ just about anything I record with this.Overall, though, an impressive microphone for the price.


Very good sounding Microphone

By BGman

from WV

The microphone sounds great on a acoustic instruments. I have a vintage Amperite RAE ribbon mic from the mid 30's and this mic out performs the vintage one.


RSM-4 on cello

By Loopcat

from San Antonio Tx.

See all my reviews

Ask me a question

Just tried this ribbon on cello. Sounds sweet,full, centered and flat. Mackie board doesn't have enough quite gain. Used a Studio Projects VTB-1 pre-amp with good result. Tested the AT4050 LDC and Oktava MK-012A against the RSM-4 and the ribbon sounded better on cello.


Clean and Responsive

By Rob the Drummer

from San Francisco

I bought this mic to record an accordion and upright bass. Worked like a charm. I have tried it on vocals, and much like the hands on review, it has an intimate sound. The figure 8 pattern nice for adding the acoustics of the room. I am considering getting a second one and trying them as overhead pairs for drums and possibly chorus. I'd love the chance to record piano with them.Thus far, it is versatile and a great first ribbon microphone. I haven't tested it on kick drum yet, though with SPL rating of 165, it should handle being an external kick mic. I might even try it on an amp rather than a condenser...
