Yeah, over thousands of feet where it actually is a transmission line
for audio frequencies. All audio is lumped parameters. Certainly
anything to do with mic preamps. But it's a pretty common mistake.
And if it *was* a transmission line, it sure looks like a 300-ohm (not
600) line to me.
Uhuh, that too !
