ATTENTION: keep low the volume! Thanks, your ears.
This is a little audio processor based on the TDA8425, controlled by a PIC16F876A.
Funcions: volume, balance, bass gain and frequency, treble gain and frequency, input selector, linear stereo, spatial stereo, forced mono, three pseudo stereo levels.
All functions are selectable with 4 push buttons and the selected function is showed on the LCD.
Song: Empire of the sun - We are the people (very cool song, in my opinion).
