LM4610

Dual DC Operated Tone/Volume/Balance Circuit with

National 3-D Sound

General Description

Features

n National 3-D Sound

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 National’s 3D-Sound Cir-

cuitry which can be externally adjusted via a simple RC Net-

work. An additional control input allows loudness compensa-

tion to be simply effected.

n Wide supply voltage range, 9V to 16V

n Large volume control range, 75 dB typical

n Tone control, 15 dB typical

n Channel separation, 75 dB typical

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

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.

Vrms

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

0.3 Vrms

n Few external components required

Each tone response is defined by a single capacitor chosen

to give the desired characteristic.
