The value of the input capacitor is important to consider as it directly affects the bass (low frequency)
performance of the circuit. Speaker response may also be taken into consideration when setting the corner
frequency using input capacitors.
Equation 2 is reconfigured to solve for the input coupling capacitance.
If the corner frequency is within the audio band, the capacitors should have a tolerance of ±10% or better,
because any mismatch in capacitance causes an impedance mismatch at the corner frequency and below.
For a flat low-frequency response, use large input coupling capacitors (1
F or larger).
