LC75412WS

Overview

The LC75412WS are electronic volume controllers that enable control of volume, balance, fader, bass/treble, loudness,

input switching, and input gain using only a small number of external components.

Functions

• Volume

: 0dB to -79dB in 1dB steps, and -

∞ (81 positions) Balance function with separate L/R control

• Fader

: Rear output or front output can be attenuated across 16 positions (in 1dB steps from 0dB to -2dB,

2dB steps from -2dB to -20dB, 10dB steps from -20dB to -30dB, and -45dB, -60dB, -

∞)

• Bass/treble

: Each band can be controlled in 2dB steps from

±0dB to ±18dB.

• Input gain

: 0dB to +18.75dB (1.25dB steps) amplification is possible for the input signal.

• Input switching : Six input signals can be selected for Left and for Right

(five are singleended inputs and one is a differential input.)

• Loudness

: A tap is output from the -32dB position of a volume control resistor ladder.

A loudness function can be implemented by connecting an external RC circuit.
