Calculation of External Equalizer Constant
Bass/Super Bass Circuit
The equivalent circuit and the formula for calculating the external RC with a mean frequency of 1000 Hz are shown
below.
Bass/super bass band equivalent circuit block diagram
Calculation example
Specification Mean frequency: f0 = 1000 Hz
Gain during maximum boost: G = 10 dB
Using R1 = 0, R2 = 33.097 k
, and C1 = C2 = C,
We obtain R2 from G = 10 dB.
We obtain C from mean frequency f0 = 1000 Hz.
We obtain Q.
