Audio input capacitor. In most circuits for amplifiers there is an input capacitor. They receive an incoming ac signal music and they amplify it for the headphones. Wikipedia shows an example circuit as well as how to pick your …
What do input capacitors provide on amplifiers? – PS Audio

I understand the input capacitor thing. But when I was both designing and building tube amps from the ground up, I went in a slightly different direction. All depending on what kind of a sound I wanted the amp to have, and whatever kind of an application I wanted to use it in. This is what I did. I would put line level transformers on the inputs.

An input capacitor is not required in the amps on this site inthe ideal situation. They receive an incoming AC signal (music),and they amplify it for the headphones. Very straightforward. But in real life, music sources have some DC offset: the ACsignal is shifted by some constant DC level.

Your input filter is a high-pass filter with a capacitor (size as yet undetermined) and 11K resistance to ground. The corner frequency f0 is equal to 1/ (2pi*R*C), in Hz. If you wanted to pass frequencies higher than 20Hz, you could use a 1uF cap. If you used 2.2uF you'd pass everything higher than about 7Hz.

F = 1 / (2 π R C) When R is in Ohms, C in Farads, then F is in Hertz. The final audio amplifier circuit is therefore: C1 attenuates components of the input signal from about 20 Hz down, and completely blocks DC. You might want something similar on the output of the amplifier.

New Coupling Capacitors for Superior Sound! The word is out among audio engineers, but is a little slow getting to the average audiophile; the quality of the capacitors in the output stage of your preamp or the input stage of your amplifier is one of the major determining factors of the sound quality. I have done four upgrades to my amplifier input stage over 20 …

Re: Audio amplifier output capacitor value. « Reply #2 on: June 07, 2020, 06:21:33 pm ». No magic about the output cap. It determines the bass cut off frequency and is easy to calculate. It's just a CR high pass filter. With a 4 ohm-loudspeaker and a 2200 uF cap, the cut off is at ~18 Hz. Caps in the feedback loop are normally for stability ...
Capacitor Selection for Coupling and Decoupling Applications

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.
