Features, Applications
DIGITAL CONTROLLED AUDIO PROCESSOR WITH SURROUND SOUND MATRIX

1 STEREO INPUT VOLUME CONTROL IN 1.25dB STEP TREBLE AND BASS CONTROL THREE SURROUND MODES ARE AVAILABLE: MOVIE, MUSIC AND SIMULATED FOUR SPEAKER ATTENUATORS: 4 INDEPENDENT SPEAKERS CONTROL IN 1.25dB STEPS FOR BALANCE FACILITY INDEPENDENT MUTE FUNCTION ALL FUNCTIONS PROGRAMMABLE VIA SERIAL BUS DESCRIPTION The is a volume tone (bass and treble) balance (Left/Right) processor for quality audio applications in car radio and Hi-Fi systems. It reproduces surround sound by using phase PIN CONNECTIONS

shifters and a signal matrix. Control of all the functions is accomplished by serial bus. The AC signal setting is obtained by resistor networks and switches combined with operational amplifiers. Thanks to the used BIPOLAR/CMOS Technology, Low Distortion, Low Noise and DC stepping are obtained.
