Design three band equalizer using Proteus

Our audio equalizer works by first receiving the signal from your MP3 player, phone, or laptop
through the Aux cable. This signal is then divided and sent to three separate filter circuits – one for bass, one for mid-range, and one for treble. Each filter allows specific frequencies to pass through while reducing others. You can then adjust the level of each frequency range using the three potentiometers. Finally, the filtered and adjusted signals are amplified by the LM386 chip to power the speaker, letting you hear your music with the perfect balance of bass, mid-range, and treble.
Our 3-channel audio equalizer is for everyone who loves music. It lets you tweak the sound to
fit any music style. It's affordable and easy to use, perfect for those who love building things.
With simple controls and a portable design, it's great for anyone, anywhere. Our equalizer makes your music sound better, giving you more control and flexibility.
As we conclude, our product has successfully met diverse consumer needs by reimagining
personalized audio experiences and providing an affordable and accessible audio enhancement
solution. Looking ahead, we plan to collaborate with audio professionals to optimize sound
quality and continuously refine the user interface for enhanced usability. Our research and
development efforts will focus on staying ahead of emerging audio trends, ensuring our product remains at the forefront of innovation and customer satisfaction.
