Dear Forum,
I have built a micropnone that incorporates a low-z mic capsule the specs are as follows: frequency response: 100Hz to 10kHz , impedance: 600 ohms +/- 30% , sensitivity: -78dB +/- 3dB. I step it up with a 1:10 impedance transformer so it is high-z. I am not pleased with the mid outputs and would like to create a low pass passive RLC notch filter to alleviate the trebble in the mids and to allow for more bass to come through. This is a very simple curcuit which consists of only three components not including the mic capsule and transformer however I do not know where to start as I am electronically handicapped.
I thought about making a little board with a variable conductor, inductor and resitor to find the tone I desire and measure the values however once again how large or small must I go - we are talking micro henrys for the inductor and microfarads for the capacitor. I do not wish to make it too tight as I think it will be too low Q so a wide notch is what I wish to have if this can in fact take that terrible trebble out of the sound it is currently producing.
I read the FAQ and I just could not find any other way than to ask the pros outright. Any help with this would be greatly appreciated!!!!
Thanks,
Chummy
