If you are looking to control your audio with arduino, here’s it is. It uses TDA7419 chip which has a lot of features for controlling your audio. It has 4 input selector, bass control, mid control, treble control, loudness control and a built-in 7 band spectrum analyzer.Continue reading “Arduino controlled bass mid treble and input selector with tda7419”
I wanted to build this project a long time ago but I have no time to do it. Today I decide to make a PCB design for it. Unfortunately I do not have any time to make the actual prototype. I will post my design so that anyone can build their own prototype.Continue reading “500W Amplifier from Eliot Sound Products”
Here’s a simple circuit you can use to boost more bass from your music. It can be powered by 9V battery or a 12V DC adapter. Take note that this is just basically a 1 band tone control with +- 17dB range at 60Hz bass frequency. You need it to connect before the amplifier input. This can’t be connected directly to speaker. The output of this circuit will be connected to the input of your amplifier and the input of this circuit will be connected to your audio source(i.e. mp3 player).
