For the record, I used one of these in a XLR version on stage as a guitar amp mic for over a decade. Fairly convinced it drank more beer than anyone on the stage. I won it in a contest, bought a second for cheaper than a SM57. My big beef was the bright blue LED, gaffer tape fixed that. To this day, still my go-to guitar cab mic. We ran a LOUD show, REALLY loud, full-on touring PA in a small club. It responded well, sounded great. Best 75 bucks for a pair of guitar mics ever spent.
@Robert Slackware Not sure if I'll be answering your question but I can tell you that phantom power is to provide electrical current to the audio signal, but is just voltage, I mean it doesn't do anything with the audio signal itself though its purpose is to amplify the signal that the delicate and extremely sensitive mechanism of the condenser microphone produces which is a very low signal and because you are working with sound the need to preamp the signal as close of its source as possible is key to avoid noise contamination, also, and probably more important is the function is that condenser microphones require a voltage for polarizing the microphone’s transducer element. ...something like that, not sure if I'm covering it all or even being accurate enough at an engeenering level, but something like that is what it does. Many times you can use a simple phantom power device that even works with a 9dc battery or 12v dc power supply, it really doesn't affect the sound quality of the signal at all.For amplifiers to work with condenser microphones you should normally use a console that can provide phantom power to the mic lines, every single console mixer in the market does so.

@@Markus0021 When i had to open up my first AKG Perception 200 (similar construction), i only had one pair of beefy-ish "needle-nose" pliers, and the tips were just the right size. Good luck using that screwdriver-method if there's any threadlock in there... :P
@@khronscave Sure, Dave doesn't have to remove Jeezless clips on a regular basis, but I don't either, and my snap ring pliers see a lot more use than my needle nose pliers. It's just a better engineered tool.
Hey the Samson honestly is the ONLY mic that works best for my voice, I have tried hundreds of mics up to $2000 , I’m curious to what I can do to the mic To get the small hiss out of it, like is there a small mod I can change out on the board to achieve that?
In cases where it's not clear if water contaminants get under SMD's etc.. I like to inject a little IPA from a small syringe to specific water trap points and then use a soft tooth brush to clean residue. A little compressed air to blow-out, and things come-out looking new!
I noticed when Dave does review or teardown, in 100% of cases, he calls everything else which is not in the video - rubbish. It reminded my childhood when I used to tell my friends "you're my best friend!" while other friend is not hearing it. Then tell the same thing to other friend while previous friend is not around.
Been using a C01U Pro for almost 5 years now, looking to finally pull it apart and clean the foam for the partial time I didn't have a windscreen over it. Looks pretty easy, Thanks!
Nope, this Doug isn't a spoiled brat bully :) I really liked the multi-part microphone series of videos. It didn't get as many views as it should have.
I use one of these for making PC repair videos on my main channel. I'm sure there's people who have much more expensive kit that can out perform it, but for a semi-professional mic setup costing less than $100 I don't think it can be beat.
Definitely not, I've had one for about 7 or so years and I still prefer to use it over my $300 Audio-Technica AT4040 mic for ease of use, and the sound quality difference is pretty negligible. It is an excellent microphone for the cost, to be sure
Lots of older cheap condenser mics are a bit noisy, actually, and USB ones tend to be even worse (ca. 30 dB(A) SPL vs. ca. 23 dB(A) SPL). A 10 meg bias resistor is on the low side (it is not unusual to find 1 GOhm parts, the reasons being explained in one of the Doug Ford videos), and most of all there's the very modest dynamic range provided by the AK5371 (a typical 84 dB(A) assuming an external preamp circuit is being used, and the 77 dB(A) dynamic range for the 20 dB fixed preamp or the 40 kOhm input impedance for the inverting PGA do not inspire too much confidence in the analog input noise floor either). There is invariably going to be a compromise between level handling and noise floor. I'd speculate that the IC was originally developed for the more modest needs of small (e.g. 1/4") electret capsules. Its limited dynamic range wouldn't be _nearly_ as much of a problem if there were a good low noise, variable gain preamp stage present in the mic, but there isn't one.
A puzzle to get you thinking: The wavelength of sound at 1KHz is 340mm. The capsulse size is 19mm. How does the capsule achieve a cardioid polar response?
Note the larger baffle around extending beyond the face of the capsule. And note the small holes in the back-side of the plate and the back side of the capsule. Those are all very carefully designed to achieve the polar response. Even 82-cent jelly-bean commodity electret mic capsules use exactly the same method (side and back ports to reduce sensitivity to the side and back.) But most small jelly-bean electret capsules are omni-directional with no side or back vents.
@@therealjammit I'm not sure the analogy matches perfectly with acoustics, but you have me interested now. Can you help me understand exactly what what you mean by riding the crest?
Great video with a very clear soundtrack, I just wanted to find out if I should talk into the end all to the front of my microphone, so this teardown is really useful. Thank you
Just one note for people taking this apart, those sprung clips either side of the chassis ping away very easily. Don't be surprised if you have to put everything down for 5-10 minutes to find out where the hell one of them went.
@@dorfschmidt4833 Seems like the Mic is still working perfectly fine after 10 Years, so it can't be that bad. And there are always Cheaper capacitors available as well. So could we stop with the claim that only Wannabe Japanese Caps are good, wich come out of the same factories as other caps because the way Chinese Industry works?? Because of the Import Tax, it has to be made in China. So only if the device is NOT made in China, the caps can be made elswhere... Where I got this Information? From a person that works for Corsair.
Nova Fawks Mod for a less durable cable and plug? Why? Remember, a USB 2 full size cable packs 4 wires in a 3 to 4mm thick cable, while a USB 3.1 C cable packs at least 16 wires into a thinner cable, making each individual signal wire much thinner and more easily broken by ordinary wear. A full digital microphone won't need to go beyond 2Mbit bandwidth, so no use for USB 3+ superspeed etc.
@@johnfrancisdoe1563 I understand that, I could change it easily again if I wanted to, the issue was the connector was already broken I only had an extra USB C female connector lying around and I needed the mic fixed asap. I would have preferred a USB B connector myself
We have come a long way from when the first modern Condenser microphone with an impedance matching amplifier was invented at what would become Bell Labs in 1917.
Thank you for this video, I bought a Samson C01U Pro a couple of years ago that from day one frequently refused to connect to and be recognised by my iMac (even though the LED on the mic lit up) and then over time would not connect to my iMac at all and today after watching your video, I took it apart using needle nose pliers to rotate the bottom ring off and the circuit board that connects to the USB B plug had semi disconnected from the 4 pin socket. When I re-seated the circuit board, it now connects every time. Now I know what to do if the problem occurs in the future. Much appreciated 🤩
@June@97 No, but I only record spoken word. I have found that a pre-amp plugin is your friend. I like Analog Obsession preBOX, CHANNEV or MPReq Pultec EQP-1A Equalizer. Also the Reaper reaFIR plugin in subtract mode can be used to remove the high noise floor.
@June@97 I'm using macOS 12.6 on an M1 iMac. I have the Input volume set in System Preferences Sound control panel at 50% and I get -18dB average no problem. As for preamp plugins, if you don't like the stock plugins that come with your DAW, I'd suggest Analog Obsession preBOX as it is free and has several popular preamps (SSL, Neve, Ampex tape, Fairchild) built in.
Electret is great for music, I understand. And probably some of the cheap audio noise meters are using electrets as. Well. When you go to the precision meters, you find there an active bias supply of 200 V DC. An electret membrane is of course plastic. Bruel and Kjaer precision meters have a metal membrane and an incredibly narrow air gap despite the high voltage. They also have a teflon cap that contains desiccant. You have to dry that desiccant every so often. Reminds me that mine is due a visit into an oven again.
That is not a 1 inch capsule, it is generic OEM electret capsule stuck into disk to make it look bigger. There are actually capsule patents from AKG and Neumann, quite fascinating stuff!
Which exact chip is used there to communicate over USB? Is it that same which has ADCs? It would be great if you could make a video how to make\solder basic USB device to PC... with USB communication basics overview... e.g. make USB device similar to MIC, but having Sin-Wave generator (or white noise generator) on-board instead.
The data sheet at 3:50 says the lone chip does USB I/O and "audio class encoder/decoder" which I'm guessing is being used for ADC, and has the potential for DAC (some USB mics let you plug in headphones, which would use it that way).
Aaaah mate. XLR ain't no that serius rubbish. Let me tell ya. A nice preamp and you are set. By the way. We've had some of these Mike capsules seeing decent abuse and they worked perfektly. Dry it up and give a shot.
Dude are you kidding me? I was talking about this mic with my friend about 2 weeks ago... And then a week later you upload this lol. Would've been cool to see this sooner)
Lol. Well to be honest, everyone who knows a little bit of (high school) physics and charging yourself, also understands that ESD safety is HEAVILY overrated. As soon as you discharge yourself and sitting still at a desk, there is no way someone will get enough charge to damage anything. At my work we just hold the frame of our desk for a bit and continue (and that's with pretty sensitive electronics)
LOL I still have the old Black and Yellow Stanley screwdriver set that I got for Christmas when I was 5 years old. Huge mistake giving me that for Christmas let me tall ya. I ripped apart every toy and small electronic device I had. Some of it never made it back together. Got zapped a few times but quickly learned about 110v and hot caps. Those old 110v high torque alarm clock motors will give ya a nice jolt lol.
So, I love my C01U, but what I DON'T love is that in order to be able to access the fade controls, you have to buy a separate program. Sure, it's only 4 bucks, but having to spend extra money just to access a feature that should be core to the microphone itself is an incredibly shit move on Samson's part, and the fact that they didn't just build that properly into the Windows driver speaks volumes.
Ah this is the Transound TSB165A capsule as I see ... it's 16.5mm diameter ... "cheapo-whipo" stuff surrounded by the porous plastic material it was used in the 70s for some toy like the small cars for kids and so on. Good for podcasts and some video VO but not exactly for Studio. Good improvement should be to replace it with a true condenser mic capsule (yes technically this is also a condenser capsule but it's electret and not what I mean). Then ad a DC/C converter to bias it with 70-80VDC. The audio quality will be improved significantly.
@@EEVblog Nah, very few mic manufacturers make everything in-house (especially on the lower end of the price range) :P Even that cast chassis and the grounding springs (in fact, the whole casing) look very similar to Behringer's C1.
If you take the capsule out of its phase correction frame, it has TS stamped on the side of it - bit of a clue there... And it's not a 19mm diaphragm - as near as dammit, it's 15mm. So basically a cheap half-inch electret. The capsule comes out quite easily if you pull the little black ring away, revealing the appalling truth about it. The best thing about these mics is the case.
@@stevegarnett6455 I kinda thought it resembled the TSB-165A, apart from the "specified" diameter. Pretty sure the slightly different hole pattern on the back (4 instead of 8 or however many might fit) is partly how they get the supercardioid pattern.
@@khronscave - could be; it does look very similar indeed to the TSB-165A but the dimensions fit the (non-available now) TSB 160A better. What's even more bizarre is the construction of the C03, which doubles up the whole arrangement so there are two of these assemblies back to back, with the separation between the diaphragms of about 25mm. They claim that by switching between them you can get figure-8, what looks like hypercardioid, and omni responses from it. One day when I want a good laugh, I'll plot the polar responses. I have no great expectations. I only got these to loan to people when they were desperate to borrow a mic - I don't want my good ones damaged and these Samsons really don't matter.
As you say, all a matter of personal preference, but: For actual podcasting (read: humans speaking), Samson Q2U sounds better, as dynamic mics give more of that "radio voice" effect. You'll say it's technically worse, but we're just used to it and associate that sound with professional voice recording. I had one and it sounded great but its foam smelled cancerous [:(], so I traded it for a Samson C01U Pro (a truly worthy upgrade over the C01U and C03U) for recording some guitalele, condenser mics are superb at that IMO. And of course now I use it for gaming and stuff, awesome piece of kit, none of that XLR ADC rubbish :) (I also had a Behringer which was awful, those people cannot into USB)
I'm having newer one C01U Pro - it has realtime monitoring headphones output, which can also be used as DAC to listen audio from PC. So I was wondering what DAC is there for the phones
Everyone keeps asking this, and I've answered it a dozen times now. There was a MASSIVE hail storm that blocked the gutters and the building couldn't handle the volume of backed up water. Shit like this happens, you can't seal building against every eventuality like this. There is no fault, the building meets the code.
Is it USB class compliant? eg driverless plug n play? I have the Rode NT-USB and it is... kinda, except it's live monitoring implementation kills any possibility for ASIO use, so kinda useless for me
Looks like some minor water damage on silkscreen area showing C12 & C13 at middle bottom of PCB at 4:57. If you watch any of 'Electronics repair school' youtube videos then a bit of Zippo petrol will sort it :-)
it is not true-condenser microphone, polarization voltage is not applied to the capsule, right? then explain why they put 510M, if there is already a bias resistor inside the jfet?
Given your vast knowledge, do you recommend this microphone for vocal recording for those who don't have much money and want to have fun without being 100% professional?
Are you sure that's a 10M resistor on the input JFET. Couldn't it be a 510M high voltage low inductance resistor? If it was only 10M the teflon standoff wouldn't be likely to be doing much. A condenser microphone capsule is a voltage source with an effective impedance of a few tens of pF and needs a pre-amp with an input impedance of at least hundreds of MΩ typically up to a few GΩ.
If an usb mic does not show up on the computer as an input, and say it is the mic is faulty, alltho led lights up and its sound thru the headphones output on the mic. Where could one start finding out the problem?
Hey is there a mod I can do on the board to get the hiss down? Either on the xlr or the USB version? This is the only mic to sound amazing on my voice but that hiss the mic gives off makes it not sound as professional

I ripped apart every toy and small electronic device I had. Some of it never made it back together. Got zapped a few times but quickly learned about 110v and hot caps. Those old 110v high torque alarm clock motors will give ya a nice jolt lol.
So, I love my C01U, but what I DON'T love is that in order to be able to access the fade controls, you have to buy a separate program. Sure, it's only 4 bucks, but having to spend extra money just to access a feature that should be core to the microphone itself is an incredibly shit move on Samson's part, and the fact that they didn't just build that properly into the Windows driver speaks volumes.
Did you ever find out how the water managed to get into the lab?
I use the Samsung Q1U mic for podcasts. This usb mic gives good service!
Ah this is the Transound TSB165A capsule as I see ... it's 16.5mm diameter ... "cheapo-whipo" stuff surrounded by the porous plastic material it was used in the 70s for some toy like the small cars for kids and so on.
Good for podcasts and some video VO but not exactly for Studio. Good improvement should be to replace it with a true condenser mic capsule (yes technically this is also a condenser capsule but it's electret and not what I mean). Then ad a DC/C converter to bias it with 70-80VDC. The audio quality will be improved significantly.
Thank You !
would be great if you could do a build/comparison for the *C01U Pro* and the *C03U*
JFET the way to go, for Mic Pre's
12:40 Well, that may very well be a Transsound capsule - probably the biggest(?) "medium diaphragm" electret capsule OEM.
Interesting. I just assumed that Samson made it.
@@EEVblog Nah, very few mic manufacturers make everything in-house (especially on the lower end of the price range) :P
Even that cast chassis and the grounding springs (in fact, the whole casing) look very similar to Behringer's C1.
If you take the capsule out of its phase correction frame, it has TS stamped on the side of it - bit of a clue there... And it's not a 19mm diaphragm - as near as dammit, it's 15mm. So basically a cheap half-inch electret. The capsule comes out quite easily if you pull the little black ring away, revealing the appalling truth about it. The best thing about these mics is the case.
@@stevegarnett6455 I kinda thought it resembled the TSB-165A, apart from the "specified" diameter. Pretty sure the slightly different hole pattern on the back (4 instead of 8 or however many might fit) is partly how they get the supercardioid pattern.
@@khronscave - could be; it does look very similar indeed to the TSB-165A but the dimensions fit the (non-available now) TSB 160A better. What's even more bizarre is the construction of the C03, which doubles up the whole arrangement so there are two of these assemblies back to back, with the separation between the diaphragms of about 25mm. They claim that by switching between them you can get figure-8, what looks like hypercardioid, and omni responses from it. One day when I want a good laugh, I'll plot the polar responses. I have no great expectations. I only got these to loan to people when they were desperate to borrow a mic - I don't want my good ones damaged and these Samsons really don't matter.
There is a popup in this video after 0:28 :-D Nice mic anyway.
As you say, all a matter of personal preference, but:
For actual podcasting (read: humans speaking), Samson Q2U sounds better, as dynamic mics give more of that "radio voice" effect. You'll say it's technically worse, but we're just used to it and associate that sound with professional voice recording.
I had one and it sounded great but its foam smelled cancerous [:(], so I traded it for a Samson C01U Pro (a truly worthy upgrade over the C01U and C03U) for recording some guitalele, condenser mics are superb at that IMO. And of course now I use it for gaming and stuff, awesome piece of kit, none of that XLR ADC rubbish :)
(I also had a Behringer which was awful, those people cannot into USB)
"those people cannot into USB"
00:26 a wild David 2 appeared!
I'm having newer one C01U Pro - it has realtime monitoring headphones output, which can also be used as DAC to listen audio from PC. So I was wondering what DAC is there for the phones
So has the landlord got the roof / original cause fixed? Would be great to find out what the cause was.
Everyone keeps asking this, and I've answered it a dozen times now. There was a MASSIVE hail storm that blocked the gutters and the building couldn't handle the volume of backed up water. Shit like this happens, you can't seal building against every eventuality like this. There is no fault, the building meets the code.
Can you make a Video on how to seal anti-static bags at home?
Mine always sounded really muffled, maybe it's just my voice lul.
Is it USB class compliant? eg driverless plug n play?
I have the Rode NT-USB and it is... kinda, except it's live monitoring implementation kills any possibility for ASIO use, so kinda useless for me
I’ve never had to install any drivers to make use of it, but I haven’t made anything more than just simple use of it so far
Looks like some minor water damage on silkscreen area showing C12 & C13 at middle bottom of PCB at 4:57. If you watch any of 'Electronics repair school' youtube videos then a bit of Zippo petrol will sort it :-)
0:28 Surprise!
it is not true-condenser microphone, polarization voltage is not applied to the capsule, right?
then explain why they put 510M, if there is already a bias resistor inside the jfet?
Can we purchase a new circuit board?
The R20 resistor is 510Mohm, not 10Mohm i guess.
Any possibility to do some teardown, or mods for cb radio?
Given your vast knowledge, do you recommend this microphone for vocal recording for those who don't have much money and want to have fun without being 100% professional?
How much did you have to claim on the old insurance Dave.?
Nothing.
@@EEVblog Good for you.. Not a tear in sight as usual. Just got on with it. 😊👍
Good 👍👍
One does not simply dissect a microphone with out a sound sample!
th-cam.com/video/4Lh4Re68Ox0/w-d-xo.html is the sample if I am correct, was linked as he talked about the history of that mic and when he úsed it.
I see lots of Samson mics at my local music store or JB Hifi.
Yes, they are very consumer focused.
we have enjoyed, well worth its money
0:27 Oh a penny!
Shhh! Don’t tell the insurance assessor that your mic still works! Hope he doesn’t watch the EEV Blog!
Are you sure that's a 10M resistor on the input JFET. Couldn't it be a 510M high voltage low inductance resistor? If it was only 10M the teflon standoff wouldn't be likely to be doing much.
A condenser microphone capsule is a voltage source with an effective impedance of a few tens of pF and needs a pre-amp with an input impedance of at least hundreds of MΩ typically up to a few GΩ.
thats a SOT23-5 package not SOT23-6 package Dave @ 4:13
I don't really see why they used a capacitor to reduce the overall capacitance of the board's plane
I dont see a capacitor on the standoff on the signal line. The red component is a 10 megaohm resistor.
It looks exactly like the behringer c1u
Very good video
I own this mic! Well, not *that* exact one, but the same model. I broke its included stand though :( Fairly quality mic
Also how come the c01u original has a brass capsule and the c01u pro has a plastic one? Does it make a different ?
If an usb mic does not show up on the computer as an input, and say it is the mic is faulty, alltho led lights up and its sound thru the headphones output on the mic.
Where could one start finding out the problem?
Data lines disconnected? USB transceiver chip (inside the mic) shot?
look up the datasheet on the USB IC in your mic and check the supply voltages going to it - always start with voltages
*a great mic* 👍👍👍👍👍
How's your singing voice Dave? Show us how well the mic works with a little song of Sex And I Know It. In speedos. For fun.

Hey is there a mod I can do on the board to get the hiss down? Either on the xlr or the USB version? This is the only mic to sound amazing on my voice but that hiss the mic gives off makes it not sound as professional
Not denying its a good mic but God was expecting a higher quality board and over all structure, I mean for the price :(
JZ Microphones is the best
Help me please! My white wire has come off from the microphone, can it be connected with something?
Soldering iron may be?
Hi i have the same microphone. The problem is that the mic works for 5 seconds when connected then its gain decreases too much. Please help.
