Stereo-tone/volume control circuit

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 d.c. 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.
