The PT2314 is a sound processor with a 4-channel stereo input selector, adjustable gain, volume control, frequency loudness compensation and tone control. I implemented the Arduino nano PT2314 project, it..

5.1 Control board project for sound system. Remote control, LCD, Encoder. I have almost no application with Arduino, I always tried to use Arduino alternatives and somehow found circuit solutions…

STM32F103, STM32F303, ATmega32, ATmega328p Amplifier control project is a control module for your audio amplifier. It supports various I²C/SPI controlled sound processors and FM tuners. All source codes and PCB..

Built on stereo tone control circuit TL072, LM358 Opams PCB dimensions are small 56x68mm. The supply voltage of the tone control circuit is unipolar. A virtual ground is created with..

The subwoofer filter, or low-pass filter, is designed to suppress high frequencies that shouldn’t be fed into the audio amplifier’s input and then into the low-frequency head (woofer, subwoofer). The..

The important thing for the subwoofer amplifier is the Bass filter circuit. Circuit TL072 Opamp is built on operational amplifier. The system’s task is to collect signals from both channels..

Active subwoofer filter circuit based on TL072 Opamp is designed for use with Power amplifier with good parameters (narrow frequency response). The transition band of the filter is between about..
