Right, I know the basics. X-Axis being Hz, Y-Axis being dB. Just curious as to why there would be two lines below 1kHz? It couldn't be a HPF
Proximity effect? If so, Should it not say the distance?

What is the chart from? If it's from a microphone spec, then it's probably from the "low cut" button on the mic.

It's from a U87 Ai ... Jesus, I woulda never thought the low cut would affect as much as up to 1kHz... Really??

Yeah, I'm no mic guru...I'd be more concerned about the hiss bump, lol.

20dB across four octaves is actually pretty smooth.
Moog lowpass filters are 24dB PER octave.
Quack!
That little bump is what they call "air".

It would be the bass roll-off switch.
This is for close work to compensate for proximity effect.
The original would have stated this.

That is part of the design of the mic. and the sound it gives.
LDCs without this are often called "dark" sounding.
