Thanks! I’m the one with the noisy KSM8, or hissy, rather. From you video, it’s clear that your KSM8 don’t suffer the same problem. I’ll have to investigate further since it does not make much sense that it would be from the actual mic. Maybe it’s a when pairing it with a certain preamp.. It happens with my Konnect48 soundcard, from tc electronic, using one of the build-in preamps, which should be quite decent.. Again, thanks. Your videos are always a treat.
@@waynebrown7065 I tried going into an old Behringer MIC100, with the KSM8 and a SM58. No noise! So maybe it’s the preamp in the K48.. I havn’t noticed it before on any other mic using these preamps.. I’ll have to go into deep doctor mode on this one.
Strctly, all dynamic mics (including ribbons) generate some amount of self noise, because temperature (even just room temperature) induces Johnson noise in all wires, including those of the mic's voice coil (or ribbon) and those of it's output transformer. In general though, (and as you've found) this noise doesn't vary much from one model of mic to another, but I've heard it claimed that some ribbons are a bit noisier in this regard because of using finer wiring in their transformers, either to achieve a higher turn ratio or just to minimise the size of the transformer.
I was the one with an issue with my KSM 8. Here a followup to my issue: I loosened the screw near the bottom of the mic, and with a plier pulled on the XLR pins. Out came a print board with 4 connector pins on top. Just reinserting it fixed my issue, and the mic is now also a whole lot louder, i.e. it needs less preamp gain. It would seem, that these connector pins can build up corrosion, so a bit of contact spray and a reseat now and then should keep this mic working great.
Hmm, that's odd. I have many mics that are decaces old and don't suffer from this. I wonder if it was/is a faulty solder joint. If it happens again, maybe inspect the solder joints and re-solder if neccessary. Anyway, glad it's working.
@@AntonBrowne I didn’t explain good enough. Inside the mic body is a print that connects to the capsule part of the mic, using 4 pins. Think jumper pins on a computer motherboard.
so from what I understand, the "noise floor" of a dynamic mic is essentially it's output impedance. ksm8 is 300 ohms, Beyerdynamic M88 is 200 ohms so it will have lower noise/hiss. but the REAL issue with mics of this caliber is cheap mic amps with a E.I.N (equivalent input noise) of like -125db or higher. if you want to hear everything your M88 dynamic mic can put out, you'll need a mic amp with a E.I.N of less than -129dbu (needs to be UNWEIGHTED noise spec into 150ohm. A-weighting gives a ~3db better number, pro audio is all about how you can lie on a spec sheet these days) I'd recommend a Cranborne Camden EC1 mic amp to really get that last 5db of signal-to-noise these classic mics can spit out. cloud lifters are trash
For what it's worth any resistive element conducting a current will generate SOME noise. Resistors do it, metal film resistors generally being lower noise than say carbon resistors. It'll turn out to be due to that Quantum thingy that rears it's ugly head whenever there's some physical property that's hard to understand.
Thanks!

Maybe you could put the mics on a stand inside of that portable vocal booth you have. Then turn the gain way up on the mixer to hear the noise.
I have ksm 8 the longer you use it the more you go back to it .
Really interessting !!
Is it the same thing With the KSM9 ?
I’m curious about the comparing KSM8 and KSM9
The KSM9 is a condenser so it will surely be noisier than the dynamics BUT even my nosiest mic isn't an issue for live work, so...
Can i get a Guide for the Best Premium Microphone (Dynamic) Cardiod for Live Speech & Vocal use ?
I reckon the sE V7 MK might be a good choice.
@@AntonBrowne awsome tk u soo much
@@AntonBrowne tk u will go for it
What microphone would suggest for a Baritone / Tenor voice? I'm a Pro singer budget is £150-300. Thanks
From mics I have... sE V7 MK. See my review.
@@AntonBrowne what about the Shure KSM8 or the Sennheiser e945?
