Hello guys,
Is a baxandall tone control circuit able to be used as a mike pre-emphasing?.

Does the electeret mikes need a preemphased circuit? If so can I use a baxandall tone control for amplifying the higher frequencies for the mike?


Thanks
 
A Baxandall tone controls circuit is fairly complicated because it has controls that boost or cut bass and treble frequencies.

But pre-emphasis is a boost to higher frequencies only. It uses just one capacitor and one resistor.

Do you need pre-emphasis for an FM transmitter? Then de-emphasis is provided by all FM radios.
 
Hello to all,

Please provide me a part No also.

Thanks in advance.

I already posted an amplification circuit for an electret mic. Why do you ask for it again?
There are thousands of electret mics available. I used some from kids toys and from telephones.
The parts available in my country might not be available in your country.
