1 RVRIN I 4dB volume control input. Must be driven at a low impedance.
2 RCOM – 1dB volume control common pin.
For the connection of capacitors that compensate for bass and treble in the tone control
3 ~ 5 RT1 ~ RT3 –
circuits.
A high-frequency compensation capacitors must be connected between T1 and T2.
A low-frequency compensation capacitors must be connected between T2 and T3.
6 RTOUT O Tone control output.
7 RSIN I Super bass input. Must be driven at a low impedance.
8 NC – Connected to VSS.
9 NC – Not used.
10 ~ 11 RSB1 ~ RSB2 – For the connection of RCH super bass compensation capacitors.
12 RFIN I Fader input. Must be driven at a low impedance.
13 RFOUT
O Fader outputs. The front and rear sides can be attenuated independently.
14 RROUT
15 VSS – Ground.
16 CL
I Serial data and clock inputs for control.
17 DI
18 CE –
Chip enable. Data is written in the internal latch when the chip enable signal goes "L"
from "H", and each analog switch is activated. Data transfer is enabled at "H".
19 VREF –
Generates a 1/2VDD power source. A capacitor must be connected between VREF and
VSS as a troubleshooting against power ripples.
20 LROUT
O Fader outputs. The frount and rear sides can be attenuated independently.
21 LFOUT
22 LFIN I Fader input. Must be driven at a low impedance.
23 ~ 24 LSB2 ~ LSB1 – For the connection of LCH super bass compensation capacitors.
25 NC – Not used.
26 NC – Connected to VSS.
27 LSIN I Super bass input. Must be driven at a low impedance.
28 LTOUT O Tone control output.
For the connection of capacitors that compensate for bass and treble in the tone control
29 ~ 31 LT3 ~ LT1 –
circuit.
A high-frequency compensation capacitors must be connected between T1 and T2.
A low-frequency compensation capacitors must be connected between T2 and T3.
32 LCOM – 1dB volume control common pin.
33 LVRIN I 4dB volume control input. Must be driven at a low impedance.
34 LSELO O Input selector output pin.
35 AUX(L)
36 CD(L)
