The bass boost part is consist of two order high pass filter circuit.
We show an example how to calculate design value of bass boost part.
We let C1=C2 are Cf and K is +1.
Above equation is shown below.
Rf=1/(0Cf) • • • (1)
R1=Rf/2Q • • • (2)
R2=2QRf • • • (3)
We let ω is 2π×70Hz and Q is 10 in the case of the cutoff
frequency is 70Hz and Q is 10.
We let C1=C2=Cf are 0.1µF.
From equation(1),(2),(3)
Rf=23.5KΩ
R1=1.18KΩ
R2=470KΩ
R1 become about 1.2KΩ,and R2 become about 470Ω
(Notice)Please set the load resistance on “fl-out(pin46)” or “fr-out(pin53)” at RL=70KΩ over.
