"WebDec 21, 2024 · The DC blocking cap does what its name implies: it makes your amplifier have zero gain at very low frequencies (DC and close to DC; DC = 0Hz by definition). Many audio sources may have a DC offset added to the signal. Such offset may be larger than the signal itself. So when you apply gain in the amplifier, that irrelevant DC offset may … " - Block dc offset
