The MS6714L is a 4 stereo inputs/2-channel outputs digital
control audio processor for the low voltage operation. Volume, tone (bass
and treble), and balance (left/right) processor are incorporated into a
single chip. The MS6714L 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.
