The ET2354 is a 4 stereo inputs/2channel outputs digital control audio processor for the low voltage operation. Volume,
tone(bass treble), balance(left/right) processor are incorporated into a single chip. The ET2354 also has the loudness
function & selectable input gain. These functions can be built a HiFi 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 & the gains of the input stage, the bass & the treble are 0dB.
