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. Features: Few external components necessary Low noise due to internal gain Bass emphasis can be increased by a double-pole  low-pass filter Wide power supply voltage range.
