Coupling & Bypass Capacitors
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.

What is a Coupling Capacitor?
In analog circuits, a coupling capacitor is used to connect two circuits such that only the AC signal from the first circuit can pass through to the next while DC is blocked. This technique helps to isolate the DC bias settings of the two coupled circuits. Capacitive coupling is also known as AC coupling and the capacitor used for the purpose is also known as a DC-blocking capacitor. A coupling capacitor''s ability to prevent a DC load from interfering with an AC source is particul…
