    Understanding bridge-tied load mode of IC audio power amps

    Hello everyone! First of all sorry for my english, I'm not native speaker) I have a question about bridge-tied load (BTL) mode in IC audio power amplifiers (for example TDA2822M, NJM2073, etc.). I spent some time trying to understand how it works but I'm confused about its schematics and...

    What should be the order of high-pass and low-pass filters in an audio amplifier circuit?

    Hey guys I am a real noob at circuit designing. Here is an amplifier circuit I put together for a center channel subwoofer of a 2.1-channel USB-powered speaker system that I am planning to build. I basically made this circuit by binge-watching YouTube videos and following the IC's datasheet. Now...
