DESCRIPTION
The LM4610 is a DC controlled tone (bass/treble),
volume and balance circuit for stereo applications in
car radio, TV and audio systems. It also features
Texas Instruments' 3D-Sound Circuitry which can be
externally adjusted via a simple RC Network. An
additional control input allows loudness compensation
to be simply affected.
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.
