DESCRIPTION
The MS6713 is a 3 stereo inputs/4-channel outputs digital control audio processor for the low voltage operation.
Volume, tone (bass and treble), balance (left/right), and fader (front/rear) processor are incorporated into a single chip.
The MS6713 also has the loudness function and selectable input gain. These functions can be built a Hi-Fi audio
system easily. All functions are programmable via the serial I2C bus. The default states of the chip as the power is on
are: the volume is -78.75dB, the stereo 4 is selected, all the speakers are mute and the gains of the input stage, the bass
and the treble are 0dB. The stereo 4 is connected internally, but not available on pins.
