Features, Applications

TONE CONTROL DIGITALLY CONTROLLED AUDIO PROCESSOR

INPUT MULTIPLEXER - 4 STEREO INPUTS - SELECTABLE INPUT GAIN FOR OPTIMAL ADAPTATION TO DIFFERENT SOURCES ONE STEREO OUTPUT TREBLE AND BASS CONTROL IN 2.0dB STEPS VOLUME CONTROL IN 1.0dB STEPS TWO SPEAKER ATTENUATORS: - TWO INDEPENDENT SPEAKER CONTROL IN 1.0dB STEPS FOR BALANCE FACILITY - INDEPENDENT MUTE FUNCTION ALL FUNCTION ARE PROGRAMMABLE VIA SERIAL BUS DESCRIPTION The is a volume tone (bass and treble) balance (Left/Right) processor for quality audio applications in Hi-Fi systems. BLOCK DIAGRAM

Selectable input gain is provided. 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
