Base treble control circuit using LM1036N

Base / treble control circuit using LM1036N

The LM1036 is a DC controlled tone (bass/treble), volume and balance circuit for stereo applications in car radio, TV and audio systems. An additional control input allows loudness compensation to be simply effected. Four control inputs provide control of the bass, treble, balance and volume functions through application of DC voltages from a remote control system or, alternatively, from four potentiometers which may be biased from a zener regulated supply provided on the circuit. Each tone response is defined by a single capacitor chosen to give the desired characteristic.

Features:

Wide supply voltage range, 9V to 16V

Large volume control range, 75 dB typical

Tone control, ±15 dB typical

Channel separation, 75 dB typical

Low distortion, 0.06% typical for an input level of 0.3 Vrms

High signal to noise, 80 dB typical for an input level of 0.3 Vrms

Few external components required

Note: Vcc can be anything betw1een 9V to 16V and the output capacitors are 10uF/25V electrolytic.
