Default What is the purpose of this automobile microphone

Much. One sort of rule of thumb is to take FM hiss, turn off the muting and see which controls have the most effect. The ones with less effect should be boosting and the ones with more effect should be cutting. But that is a very rudimentary primer on it. People used to bring their cars to me to have me set the EQ, back when you could. Houses to, in factr I modified an EQ for a friend of mine because it was only a 5 band and he needed slightly different frequencies. I turned the 60 Hz control into about a 40, the 250 into a 150, left the 1,000 alone and the 3,500 but extended the 15 KHz to infinity by removing the inductor. Also the new 40 Hz control's range extended to subsonic. I used resistance and whatever to get the range where I wanted it with the same inductor, but the cap I took to about 10 X its original value.


5 band graphic eqs were crap, but the worst thing about them was that they wasted one of the sliders on a 1kHz band.



You know this mic in the car **** is just a ruse. Like a Rube Golberg design. It will set the sound flat, but wait, they have the same data from the other 999,999 of those cars they sold. So bottom line it is a gimmick/


Speakers vary though.
