IC, LC75374E

1 RVR IN I 4dB volume control input. Must be driven at a low impedance.

2 R COM – 1dB volume control common pin. (Connected to GND through a capacitor)

For the connection of capacitors that compensate for bass and treble in the tone control circuits.

3 ~ 5 RT1 ~ RT3 – A high-frequency compensation capacitor must be connected between RT1 and RT2.

A low-frequency compensation capacitor must be connected between RT2 and RT3.

6 RT OUT O Tone control output.

7 RS IN I Super bass input. Must be driven at a low impedance.

8 NC – Connected to GND.

9 NC – Not connected.

10 RS3

O For the connection of RCH super bass compensation capacitors.

11 RS OUT

12 FR IN I Fader input. Must be driven at a low impedance.

13 FR OUT

O Fader output. The front and rear sides can be attenuated independently.

14 RR OUT

15 VSS – GND.

16 CL

I Serial data and clock input 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

GND as a troubleshooting against power ripples.

20 RL OUT

O Fader output. The front and rear sides can be attenuated independently.

21 FL OUT

22 FL IN I Fader input. Must be driven at a low impedance.

23 LS OUT

O For the connection of LCH super bass compensation capacitors.

24 LS3

25 NC – Not connected.

26 NC – Connected to GND.

27 LS IN I Super bass input. Must be driven at a low impedance.

28 LT OUT O Tone control output.

For the connection of capacitors that compensate for bass and treble in the tone control circuit.

29 ~ 31 LT3 ~ LT1 A high-frequency compensation capacitor must be connected between LT1 and LT2.

A low-frequency compensation capacitor must be connected between LT2 and LT3.

32 L COM – 1dB volume control common pin.

33 LVR IN 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)

I Signal input pins.

37 TUN (L)

38 TP (L)

39 VDD – Power supply.
