Oh ok, litz wire, that's what I was talking about. Thanks.   I just found some on ebay, but mostly as single runs of it, like this: 10-46 Litz Wire Loop Antenna Ham Crystal Radio 200 ft. (I don't want to say single "conductor", because it's already 10 conductors offered as one. but hopefully...

Some of the best stuff I saw from navships was this: 20 feet 22 AWG Shielded Silver Kapton Teflon Wire 3 Twisted for $25.   I could see this as good for point to point cabling, but for headphones it seems like it would be real stiff. Also, it doesn't seem like the best price.   What I'm...

Ahh, ok. Those calculations make more sense now. I'll try the resistances for the 50 dB drop with 2K ohm impedance.   I still don't know about the output impedance question. But some systems may not be designed for use with different mics.   I'm not familiar with the term Phantom Power...

Yeah I know a potentiometer would be easy to wire, but finding one that is logarithmic and has the right ranges on BOTH sides of the wiper seems like quite a task. Although most likely because I don't even know the values or ranges I need to find. But also because I'm pretty sure that the ranges...

Hmm... is there perhaps a better place to post this?

Bump.

I have some questions for building an attenuator, specifically, on the impedance the connected devices will see from it.     I want to connect a Line level source to a mic input. So I want to make an attenuator like one of these. Because I didn't see any mention of advantages from one...

I'm still looking for answers to the questions in my first post, however, maybe I can also get a quick answer to something else. In the schematics I linked to, there are unmarked transistors... what are good choices of transistors for audio circuits such as these?

So the most basic mixer shown here simply attempts to detur the signel from heading into the other sources by way of the resistors (and upping the impedance into that section of the circuit), and (whether the other sources are on or off, as long as the sources aren't the same strength) a small...

Hi. I have a few questions regarding combining audio sources. I'm hoping this is a good place to ask. I first assumed it would be as simple as wiring two outputs to one input (in fact, I've done this before... so I know it can work fine in some situations). However more recently, a...
