I don't think you need to worry about that. The Capsule portion of the circuit is a high impedance zone so the difference between output impedances is going to be negligible. Just put a capacitor in between your line-out and the microphone to prevent damage to your interface. There is a post somewhere (on this thread or maybe the build thread) which goes into a little more detail on this.I have a question that I suspect will out me as the mic novice that I am. I haven't yet biased the FETs in my pair, but I have watched through the video suggested in the guide. I do not have bench testing equipment -- I typically use my interface and DAW for tone generation / meters / etc. It seems simple enough to do that here as well, except that I'm wondering if a line out from my interface would cause problems in the measurements due to mismatched impedance... I know that mic output impedance is quite low, but I don't know what injecting a line level signal in would do. Or perhaps I'm overthinking it.
Also, I've got a TS-to-alligator clip cable. Would this work here, assuming that the above is not a concern? Or would I need to figure out something with a TRS connection?
Also, still no word from the powder coating shop. I'm too impatient.
TS alligator clip is fine, you don't need a balanced signal to the mic. Just keep the runs short.
Also, anyone correct me if I am wrong (I am a relative novice particularly with microphone circuits).
