Glad to hear it.

This mod works very well in my use cases. Now I can use BM800 at group calls without annoying noise Thank You!

Nice mod - I'm not too surprised that supply voltage doesn't have much effect on sensitivity with an electret capsule, it's a far bigger deal with an externally polarized capsule. Looking at the schematic I was initially surprised at the lack of a source resistor on the FET, but it seems that the 2SK596 is a trick JFET with a built-in bias resistor - neat.

I've been looking for this for years

Really cool hack! Have you considered soldering a 10...100nF Foil Capacitor paralell (with lower ESR an less parasitic Inductance) to the 100uF Elko in order to reduce the higher frequency part of the noise?

Really nice mod, sounds better. Thank you for the info.

I've done the mod but...will it continue to work with phantom or do I change the value of the condensers (60V) and the zener (what voltage?)?

With a good preamp, it would probably be still useful even at 3 volts. Most electrets are quite happy to run at a variety of voltages, provided there is a preamp with clean gain.

I have a BM-700, that had no zener diode there only a little black smd part that I couldn't recognize, but the circuit looked the same apart from that. I added the capacitor and the resistor and it made the necessary improvement but later I removed the tiny black whatever it was and replaced with the 11V zener. I don't hear any difference in the recording from this last step but I'm not a measurement tool, but when I changed the speakers to a earphone I can hear some constant background noise, not very loud but it is there. Sadly it would be impossible to put the original tiny black part back to test if that had it as well because it is so tiny (probably it had) but overall I'm very happy with the results because I don't hear that in the recording. Before I had awful lot of noise I couldn't know how to remove. This is a huge improvement. Thank you! I have a new big capsule I plan to try with this. Hopefully that would improve the sound even more.

Did the capsule work well?

What upgrades would you recommend to the Avantone Ck-6 microphone? Schematic would help?

I have done the mod on a nw800 that is the same or the bm, the circuit is the same Just few differences in component position. The result is appreciable, I obtained that the microphone can works with less gain on the mixer/audio interface then the sound is more natural and clean. Nice idea but you don't expect a miracle mod because you have to remove the noise by post-editing if you want a very clean and perfect audio track.

Approved, improved signal-to-noise ratio.

I'm happy, there used to be a high pitched noise and now is gone, plus some kind of noise immunity when touching the mic. I harvested a low ESR cap from a router and ordered zener diodes, tin solder paste and a matching 1k ohm resistor. The resullt is great! There is still noise but I think it is because of my motherboard's soundcard. I'm a newbie in electronics and I really liked this little mod, it cost me more effort than necessary but hey I ended soldering a freaking 0204👍

"calibrated snake oil detector" good one right there =)

Done!!! It work well. That kind of strong white noise was considerably reduced at 70%! Next step is to try to replace the 16 mm capsule with a 34 mm gold plated milar one. Thank you!

This isn't so easy. That capsule is a true condenser one and needs to be polarised by something like 60-100V to work. So microphones that come with those have a second companion board to boost to higher voltage. It's probably less confusing to rebuild the electronics altogether. There is a different capsule that you can try, it's a 26mm electret condenser capsule, it should work as a direct drop in replacement. Just as long as your microphone has a JFET on the board rather than in the capsule. Neewer seem to be using one in the capsule, and also disguised a smaller capsule as a larger one.

Would 10v Schottky diode also work? and what mV or current one should choose when selecting this 11v or 10v diode? Thank you for this mod. Is noise floor now completely gone or up to par with AT2020 mic? Just curious.

hello interesting video,will this mod work on other mics?

Im now curious how different mine would be after the mod. Becuase ive already connected a 10uf capacitor at the 2nd pin of the XLR and im planning on adding another 10k resistor on the bridged connection of the pins 1 and 3 instead of just wire.

I agree. There is no capacitor after the emitter follower, and the noise in the voltage regulating transistor is not bypassed in any way. I suggest a combination of an electrolytic capacitor (e.g. 10µF) in parallel with a ceramic capacitor (e.g. 470pF). The reason why is that electrolytic capacitors have some reactance at higher frequencies were the ceramic type will compensate. Beside that - this is a great microphone with a quite large membrane electret element for it's price.

Can you show what parts i need and where to add them? Does you mod compatible with mod described in video?

Looks like the Neewer NW-700 has a circuit that while not entirely the same, appears virtually identical in the portions relevant to this mod (Podcastage is showing board shots in his recent NW-700 re-review: kzread.info/dash/bejne/fqGGqMtqZq66qdY.html ). Here's a little trick: You can potentially reduce zener noise by orders of magnitude by going with a stack of 4x 2.7V in series rather than the single 11V (even 3x 3.6 V or 2x 5.6 V would be an improvement). Around 3 V it's almost entirely zener effect at work, while at higher voltages the much noisier avalanche effect is increasingly dominant. This is why zeners have a near-zero temperature coefficient around 5 V in the first place, both effects' tempcos cancel out. The downside of this trick is that zener impedance goes up considerably at low voltages, i.e. regulation becomes noticeably less tight in the face of varying zener current. It could be a factor of 3 worse with 3x 3.6 V and a factor of 6 with 4x 2.7 V, and that's compared to the 11 V which would be about a factor of 2 worse than the 9.1 V to begin with (MMBZ5221-5259BW datasheet). I am not worried about PSRR as filtering is good, but the variation of zener voltage in the whole

do you know what type number of the JFET transistors used on that board....3x PNP transistors and the one NPN transistor?

For some reason my specific unit has an extra pcb completely unconnected from the main pcb. It just so happens that this board has a 470 Ohm resistor on it. Very convenient, I only need the capacitor now!

Did you not find this mic overloads very easily? I get output clipping if the singer is closer than 0.6m from the capsule. I'm currently working on getting more volts across the collector-emitter of the two output follower transistors. Also my mic has only 0.6V across the 2k2 drain resistor (48V phantom supply). I would like to increase that.

I just did this mod but with the 470R series resistor and 100uf capacitor (no zener mod) the supply voltage for the FET is around 8.3v with this and does not appear to adversely affect sensitivity. I also doubled the 22uf and 47uf capacitors whilst I was there. The noise is now virtually undetectable when I run this on a 48v phantom, where previously it was atrocious. Thanks for the video !

The higher voltage zener is necessary to make up for the voltage drop across the resistor. Without a higher voltage zener, you run the mic capsule at a lower voltage and reduce your sensitivity. The higher value resistor and higher voltage zener you run, the more damping you get, and the better noise floor you get, until you start running into resistor noise issues. My version of the mod is what worked best for me.

Very clear and precise explaination. So it seems the 48v phanton power value is for antique mics. Your pc supplies just barely enough power to run the mike adequately, and about 9-12 volts are ideal. I have a czn-15n condenser mic for my presentations and plan to do similiar mode. Thanks for this.

The 78XX series regulators are way more hi-tech than the circuit in this microphone, and they're prone to oscillating without some input and output capacitance - you'll notice that they usually only spec a tiny capacitor on the output. Quoting TI's datasheet, "Although no output capacitor is needed for stability, it does help transient response." Again, I'm not arguing that an extra 100 nF cap would be BAD - I'm saying that it'd be superfluous in this circuit. There's nothing there to generate HF noise (there isn't even a feedback loop), and noise above 20 kHz in a microphone is barely worth considering on its own unless it's causing more severe issues.

Hi, please help. Today I got my BM 800 and was immediately disappointed because of the high noise level and low signal level (i have phantom power 48v and sound card Asus). According to your instructions, I added a capacitor of 16 volts 470 microfarads and a resistor 1k (also tried 360 ohm but did not notice the difference). I did not change the zender because I dont have it. Then I checked and was disappointed, the noise remained, exactly the same. But I noticed that I have 6.7 volts on the capsule and I think the whole problem is in this?

Is a 11v Zener or 2v Zener?

It's definitely not a 2 V zener.

hey, can you use this mod together with phantom power or audio interface that has 48v

@@FFcossag WTF? works perfectly fine on 48V. the cap can never see more than Zener voltage anyway.

This stuff is not dedicated to musicians. They recognize only a shape and a brand. Otherwise excellent upgrade.

can i install common resistor for 1K ohm R (not SMD)?

There's no difference between SMD and through-hole resistors, other than the size.

Hi. I don't know enough of electronic stuff. ...Actually I don't know anything. Anyway, I can't find a 100μF - 16 V capacitor. I found a 100μF 35V cacapitor. Can I, however, use it for this hack?

i have the same mic ,but i use this without 48v phantom ,because im using a USB sound card betwen mic and my computer , better sound ,and NO noise , you can try test this in audacity with and without usb sound card . ;)

It works better than tiny mics on sound card power, but sensitivity is way down compared to when it's used with a real PSU.

After this, upgrade the capsule to 25mm back electret one, then it will be the big different...

Does anyone know if the circuit is the same in a NW800? It seems like it's a clone of this mic, but it's a bit cheaper

From the sound tests I have heard the NW actually sounds a little better than the BM, I might buy both with hopes that they have similar circuits, enough to make this mod good for both at least. Need some options for recording guitar cabs!

Just plug your xlr cable in the back of your pc

I did this mod , but the 100ohm and new zener did not work for me so i did the orignal mod and it works a treat . The noise floor was so bad i had to use a high pass filter and a 26db pad, and the pre amp maxed. Now both are off and the pre amp is down to 30% .
