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.

Coupling capacitors are essential components in amplifier circuits. They are used to prevent interference of a transistor's bias voltage by AC signals. In most amplifier circuits, this is achieved by driving the signal to the base terminal of a transistor through a coupling capacitor.
Technical Question About Capacitive Coupling in Amps ...
https://forum.polkaudio.com/discussion/195640/technical-question-about-capacitive-coupling-in-amps
If there are capacitors between amplifying sections ("stages") of an any amplifier, yes, the amp has capacitor coupling. Indeed, it wasn't uncommon to put a DC blocking capacitor on an amplifier's input , since a fully direct-coupled amplifier could dutifully amplify any DC "bias" that might be riding under the (AC) input signal ("music"!) -- with potentially disastrous results for …

Use of Coupling Capacitors. Coupling capacitors are useful in many types of circuits where AC signals are the desired signals to be output while DC signals are just used for providing power to certain components in the circuit but should not appear in the output. For example, a coupling capacitor normally is used in an audio circuits, such as a microphone circuit.

Coupling capacitors are used to block D.C. (D.C. = bad Ju-ju) , and pass A.C. (A.C. = the music signal). However, a coupling capacitor acts as a high pass filter, meaning it will attenuate frequencies below a certain point.

HIGH-POWER & LOW-VOLTAGE AUDIO POWER AMPLIFIER GENERAL DESCRIPTION The NJU7089 is an audio power amplifier designed for telephone applications. No external coupling capacitors are required because of the differential outputs. The closed loop gain is adjusted by two external resistors, and a SD pin permit power down with muting the input signal.
