DESCRIPTION

The MS6712L is a 4 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 MS6712L 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.
