LM1036
Dual DC Operated Tone/Volume/Balance Circuit
General Description
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 loud-
ness compensation to be simply effected.
Four control inputs provide control of the bass, treble, bal-
ance and volume functions through application of DC volt-
ages 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.
