Philips Semiconductors
GENERAL DESCRIPTION
The device is designed as an active stereo-tone/volume
control for car radios, TV receivers and mains-fed
equipment. It includes functions for bass and treble
control, volume control with built-in contour (can be
switched off) and balance. All these functions can be
controlled by DC voltages or by single linear
potentiometers.
