GENERAL DESCRIPTION
The S1A0501X01 is an audio processor for volume/tone/fader control, which is suitable for car radios or Hi-Fi system. It has a built-in trimmer for user to set a source level. R/L rear output is changable to input in the case of a home audio system for user conveniency, an external equalizer or a noise reduction circuit is selectable. When the S1A0501X01 is used with some sound-effect equipment such as graphic equalizer, the internal tone control block of S1A0501X01 can be bypassed for decreasing redundancy. All selections and function controls are designed to be controlled by an I2C-bus protocol or a general microprocessor interface protocol. 32−SOP−450B
