I built this Bluetooth speaker for such a person who is passionate about music and sometime sings songs using karaoke just for fun. He is not a rich person as just sells tea in his tea store at my locality. So, I tried to minimize cost just by using old materials for the enclosure & old electronic components from previous projects.
It has two public announcement microphone inputs with volume & reverb level control knobs. Audio from the microphone directly mixes with the Bluetooth module audio out which has many features like Auxiliary Input, FM Radio, MicroSD card slot & USB support apart from Bluetooth. This 2.1 speaker system powered by TPA3116D2 2.1 200watts amplifier board with bass & tone control. From 24volt power supply it can deliver up to 200watts RMS, but as I have connected 12Volt 10Amp SMPS, it should give little less than 100watts sound output.
Thanks for watching. please like & comment and share with your friends, goodbye for now.
