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 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 poten-
tiometers 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.
