The idea of this TDA7313 based audio processor was to create a circuit capable to control all basic audio settings with the use of buttons and a LCD screen. When this idea realized, this board was born! We talk about this incredible 3 channel audio processor that is capable to control Volume, Bass, Tremble, Channel Select, Input gain for selected channel, LF speaker attenuation, RF speaker attenuation, LR speaker attenuation, RR speaker attenuation. It can be embedded on every audio system, the possibilities are endless. Video demostration comes next.
A little talk about what TDA7313 offers:
TDA7313 audio processor have been used for more than ten years in the industry because of its simplicity, functionality and good parameters like low distortion, low noise. Chip is based on BIPOLAR/CMOS technology and can be used in various applications including car radios, Hi-FI, simple mixers.
TDA7313 chip has 3 external stereo inputs, that allows to multiplex three incoming sound sources, volume control with steps of 1.25dB, Treble and BASS control, Loudness function, Each of four outputs have distinct control that allows to balance outputs. Chip can be controlled via I2C (TWI) interface.AVR based TDA7313 Audio processor control - [Link]
