This ti precision design details the design process for a preamplifier to be used with electret microphone capsules. The postamplifier is typically a gaussian shaping amplifier that improves the signal to noise ratio by limiting the bandwidth. In later diagrams korg draw it as a set of triangle amplifiers with summed outputs and i thing this approach is the most legible. Amplifiers can be thought of as a simple box or block containing the amplifying device, such as a bipolar transistor, field effect transistor or operational.
