This is a high impedance input 2 stage preamplifier that features an adjustable voltage gain, from 1.5 to 10. This gain can be varied by setting up VRI and becomes handy where the MIC sensitivity required to be varied often. As shown above, the circuit is actually designed for crystal microphones or ceramic cartridges.
