Circuits controlling the audio signal tone control, bass, treble filter circuits, vu meter display and similar audio electronics circuits
The circuit effectively protects the sensitive tweeter within a speaker cabinet from overload. It was specifically designed to prevent damage to tweeters, particularly at high volume levels and under faulty..
This is a project to repair a faulty volume control potentiometer on an Odyssey-U-010 amplifier. In the original setup, large resistors were soldered to the top. Instead of using a..
Active crossover is an improved solution for loudspeakers compared to traditional passive crossover circuits. It provides excellent flat system frequency response and reduced distortion. Phase-corrected active crossover: An active crossover..
“Mastery is gained through practice.” This saying is especially true for guitarists. However, loud guitar practice often leads to problems with neighbors. That’s where a compact and convenient guitar headset..
This 10-channel equalizer with loudness feature operates with a ±12V DC symmetrical voltage. Current consumption is approximately 40mA. The slider potentiometers are rated at 100 kOhm with a 30mm stroke…
Combo amplifier system is designed to amplify and modify the signal from electric guitars. The signal is processed in two channels that produce clean or edited sound. The channels can..
PT2399 circuit Heavy filtering allows for useful delay times and typical analog-like sound. The delay line starts just after 100n (after J112 JFET transistor). This capacitor is just a coupling..
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..
