TDA1524 tone control, The article is based on a TDA1524a class of an IC-based tone control circuit. With few components will efficiently control a stereo input. The main advantage of this pre amp board is the minimal of the components. You can use a single channel variable potentiometer on this board to control the bass, treble, and master volume.
PCB Layout
The input voltage is 12v single Power supply. You can adjust the loudness of the output signals by shorting the loudness jumber.
Features
- Few external components necessary for working.
- Low noise due to gain.
- High bass injection.
- Wide range of supply voltage.
Circuit Diagram
To control the tones You can use 47k or 50k variable potentiometer. The IC is designed as an active stereo tone control for home and automobile. It includes the function of bass, treble, volume control. All these functions are controlled by DC voltage and control by linear potentiometer. Supply voltage is 12v.
