FUNCTION DESCRIPTION
(1)INPUT SELECTOR,INPUT GAIN,INPUT ATT
This IC is build in selector with 2ch 6input+mute.
The Input selector is able to control source signal level at 0dB or -5dB by Input ATT Switch.
And , for low level source signal it is able to change the gain by Input Gain Switch.
But There is a restriction on combination of ATT level and Gain.(Refer to below table)
<Input ATT and Input Gain possible to combine>

(3)Microphone mixing
The microphone signal is mixed on L-ch or R-ch after pass through the buffer for decrease in
crosstalk between L-ch and R-ch.
The signal level mixed on is 0dB.
And , This IC build in microphone mute switch for the purpose of improving noise characteristics.

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.
