LC75412WS ^{Electronic Volume Controller}
for Car Audio Systems
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
• Fader
• Bass/treble
• Input gain
• Input switching
• Loudness
: 0dB to -79dB in 1dB steps, and -∞ (81 positions) Balance function with separate L/R control
: 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, -∞)
: Each band can be controlled in 2dB steps from ±0dB to ±18dB.
: 0dB to +18.75dB (1.25dB steps) amplification is possible for the input signal.
: Six input signals can be selected for Left and for Right
(five are singleended inputs and one is a differential input.)
: 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.
