[Elecraft] CM-500 Response (was: Heil HC-4, HC-5)

[Joe Subich, W4TV]

In order to have reasonable articulation, the CM-500 
needs at least 3dB (closer to 6dB) per octave of boost 
above 800 Hz and requires 6dB per octave of cut below 
400 Hz in order to avoid being "boomy" or "muddy."  

It should never be necessary to use that much EQ to make 
a microphone "sound good" and is a symptom of a poorly 
designed capsule (or preamp). 

73,
