Hi, I have a problem with audio hum when powering in/out from power supply. Can this problem be solved? (PAM8403 audio amplifier) Thanks.

Very good explanation. Thx

Video bahut hi accha hai..thank u

Sir mere sath same problem hai . mene do keyboard ke audio out Jack se seprate silded cable se mixture me input kiyaa hai or mixture ke audio out se amplifier me input diyaa hai agaar keyboard off hai or amplifier on karne par humming suru ho jatta hai. Sir ye mp3 kit laganaa jaruri hai . ke sirf circuit banaa ke sidhaa input de sakte hai. Please inform

Thank you my bro

Thanks brother

Sir, agar usb bluetooth kit ko bass treble bord me conect karna ho toh.... Capacitor ka value konsa hoga....? Please sir , reply me

Sir mara ap sa ak question hai Mare pass do amplifier hai 60 watt mono agar may amplifier ka jo sound output ka negative point do no ka agar ak sath cunnect ka du to Kaya sound quality may kuch farak para ga Plz batiya sir

Bhai ye ager ye volume control ko capacitor laga k jo blutooth kit se ate h LGR to in me capacitor laga k aur capacitor ke LGR wire ko volume control me lga aur volume control ke wire amplifier me lga k esa connection kre to problem solv hoga kya humming ka

Bohot accha.

There are two way to get rid of this humming problem.... 1. Give a separate power supply to the Bluetooth decoder... 2. Don't connect the ground wire of the Bluetooth decoder to the amplifier... Connect only the R and L wire to the amplifier.....
