Role of capacitors in amplifier

A coupling capacitor can mean many things so I''m just going to focus on a signal coupling cap and its significance. On an input it prevents microphones and guitars (for example) ruining the bias levels of the amp - it won''t work if you don''t have the capacitor. On an output it pretty much does the same thing - any resistive load will upset the ...
