Hi friends,
I am looking for a fair microphone preamplifier circuit that must be used with my car amplifier at 18 to20 volts.
The amplifier chip is able to support that voltage.
The microphones which I want to use are condenser and dynamic microphones.
Is there any guy who knows a suitable circuit for the job?
The amplifier is working ok with the output signals coming from my radio, walkman and PC, so can I use the input of my wanted preamplifier with those devices too or I need 2 inputs, one for my microphones and the other for the devices?
By the way I have few head preamplifier circuits based upon 9411 preamplifier chips too but some guy here said me that those circuits are not good when are use on the common circuitry.
