Description
The MS6720L is a 3 stereo inputs/4-channel outputs digital
control audio processor for the low voltage operation. Volume, balance
(left/right), and fader (front/rear) processor are incorporated into a
single chip. The MS6720L also has selectable input gain. 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 are 0dB. The stereo 4 is
connected internally, but not available on pins.
