2.0 - Coupling Capacitors. The purpose of a coupling cap is to pass the wanted audio (AC) signal, while blocking any DC from preceding stages or source components. DC will cause pots to become noisy (scratching noises when operate), and cause relatively loud clicks when (if) muting relays or similar are used.

The role of coupling capacitors is to prevent the incoming AC signal from interfering with the bias voltage applied to the base of a transistor. In such applications, the signal is driven to the base of a transistor through a serially connected coupling capacitor. The capacitance value must be chosen so as to allow the useful signal, for ...
