Equipped with Infineon's new amplifier IC! It provides high sound quality and excellent audio performance with extremely high energy consumption efficiency. The A300 can be used in stereo 165W + 165W, and in BTL mode, it becomes a 330W high-power monaural amplifier, allowing you to build the optimal system to match the speakers you use. Usually, it is combined with a pair of passive speakers to form a 2.0ch Hi-Fi sound system, but if you need super bass, you can switch the A300 to high-pass mode (it is also necessary to switch to stereo mode), cut the bass in the stereo section through the internal high-pass circuit, connect a subwoofer with the SW terminal, and create a 2.1ch sound system that produces plenty of bass! Compatible with Bluetooth 5.0 input. Enjoy the best music wirelessly anywhere!
