User friendly TDA7313 audio processor control board

Scienceprog has built an audio processor control board with 3 selectable stereo inputs and four outputs. System is built to be a stand-alone device, that can be embedded almost in every audio system. Audio-processor is capable to control Volume, BASS, Treble, attenuation of each output channel.

There is very intuitive menu control installed – parameters are changed by inspecting visual bar in LCD. All Tda7313 functionality is covered with only 5 buttons. Device can also remember last parameter settings. So each time it is powered – last saved parameters are loaded. All project files are available for download including Eagle project, WinAVR project and pre-compiled firmware.
