Preamplifier Microphone with 2 Transistor
Microphone preamplifier or often known as mic preamp can be made use simplemicrophone preamplifier circuit as follows. 2 microphone preamplifier circuit uses 2transistors are PNP and NPN transitor amplifier.
Front of the microphone amplifier orpreamplifier microphone 2 transistor uses a system of dc negative feedback through R6which serves to provide stability strengthening. Level output signal from the microphonepreamplifier is controlled by potentiometer P1. Input signal that can be responded well by this microphone preamplifier is 0.2 - 200mV and 1V RMS output will result.
Microphone preamplifier circuit two transistors in the show above is preampmic suitable for home audio system on the stereo. This microphone preamplifier circuit requires supply voltages 9Vdc.
