Graphic equalizers were one of the more popular elements of audio sets in the 80s -90s of the last century. These devices allow to change the characteristics of the audio track so that it is possible to 'fit' the shape of the room and the listening room, its furnishings and, above all, the preferences of the listener.
Kit allows you to make a device that is on the edge of digital and analogue technology. The main element shaping the audio waveforms is a merged, 5-point graphic equalizer with digitally controlled I2C bus. It allows you to shape waveforms, incorporates a precise 48-point attenuator and all this with very low distortion and own noise. The entirety of the graphic equalizer is controlled by the microcontroller from the ATmega series

The device is especially recommended for audiophiles - electronics and not only
