Looks great!

The colour certainly wouldn't put me off, in fact different colors from standard would be a plus. As long as there was nothing too bright and garish, but you are not suggesting that!

I see a couple of schems in the files area that show the neutrik NTE-4 used in mic circuits. has anyone got any advice or experience about using that line of tiny neutrik transformers in mics

Hey all. We're wrapping up development on the K67 capsule here, and since we're doing everything from scratch, I figured I might pick a color for the plastic ring other than white or ivory. I want

so I looked up the KM-88, interestingly it had a removable capsule with a 4 pin connector. looks like you needed a screwdriver to change capsules though... Come to think of it you could make a 3 wire

yes, I stated this wrongly in my OP, assuming that it was the backplate that was connected to the outer shell. It makes no difference to the main issue though. I had wondered what level of

Jerry pretty much covered the impedance angle. Tube mics typically used to use 100 Mohm resistors because grid current was too high for 1 Gohms, but noise was higher than in modern FETs too. There are

Thanks Jerry! That confirms what I thought but wasn't sure. Are there any effects on frequency response or transient handling, or any other sound quality issues? It seems odd to me that Neumann or AKG

As others have said, yes they are true condensers. PCBway do 5 pieces by default. Still very cheap. The quality is excellent. The PCB job configuration options are a little confusing, but if you stick

Probably a matter of tooling. Yes. Ther

There are two scenarios for connecting a single sided capsule with external polarisation. 1. In a typical LDC you would normally connect one side of the capsule to the polarisation voltage and take

Ok I'm not sure if this should be a new thread, as it is not about a TSB2555 It is relevant to padding in general and to drum mics though. Yesterday I received a new batch of PCBs including a version

You will have to add components to the PCB’s. Good luck! If you need help we are here. Best Regards, Jules Ryckebusch

They look like typical Chinese K67 style capsules. You will want to implement some aggressive high-frequency rolloff in the circuit to correct the response of these capsules. Otherwise the microphones

Capsules arrived. Are these true condenser type? I was thinking going the pcbway and buy your pcb's, the Dual Alice and the Hex Inverter. 1st time on pcbway, they do 5 pcs by default? Do they include

This is great. And verifies what I was seeing with 220pF I had about 15-16db padding. You are showing 20db with 270pF. Thanks for doing this! Danke! mit freundlichen Grü?en, Jules -- Best Regards,

ok, the picture turned out pretty small, try it now as a pdf the cap values are 0, 100pF and 270pF

Thank you!!!! This is great Best Regards, Jules Ryckebusch

I measured the freq-response of a mic with Jules OPA circuit, TSB2555 and different values of the pad cap.

As Jules said above, I made some mics with a switch, but I also made some with headers (is this the right english term?) so I can change the caps pretty easy and experiment with different values and
