Product Summary

The LM4610N is a DC controlled tone (bass/treble), volumeand balance circuit for stereo applications in car radio, TV and audio systems. It also features National’s 3D-Sound Circuitry which can be externally adjusted via a simple RC Net-work. An additional control input allows loudness compensa-tion 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 fourpotentiometers which may be biased from a zener regulated supply provided on the circuit.
