SHURE is an American corporation produces consumer and professional audio-electronics manufacturer of microphones, phonograph cartridges, discussion systems, mixers, wireless microphone systems and digital signal processing.
The following schematic illustrates the simple Audio Level Controller Circuit Diagram designed and produced by SHURE microphones and electronics components. All the capacitors in MFD unless shown otherwise and working voltages over 100 unless shown. All resistors 10% tolerance. The selected resistor is chosen to adjust point where regulating action starts to corresponds to distance selector switch settings.
