This is exactly why I do not understand why Heil dropped the HC-4
we all do not own rigs with EQ in them. I bet that are many times far 
more rigs out there on the air that have no capability to modify the 
Mic's audio. I am soooo glad I was able to buy the last Heil set I could 
find that any store had, that still had the HC-4 in it.
