A conversion adapter only changes the plug shape and does not adjust voltage. Using only a conversion adapter without a transformer may result in damage to the product. 【Liability】 We are not responsible for malfunctions or damages caused by improper use, such as operating the product without a transformer. ----------------------------------------------------------------------

Equipped with a new Infineon amplifier IC! With excellent energy efficiency, it provides high sound quality and excellent audio performance. The A300 can be used in stereo 165W+165W mode, and in BTL mode it can be transformed into a high-power mono amplifier with an even higher power of 330W, allowing you to create the optimal system to match the speakers you are combining it with. Normally, a 2.0ch Hi-Fi sound system is created by combining it with a pair of passive speakers, but if you need ultra-low bass, you can switch the A300 to high-pass mode (you will also need to switch it to stereo mode), cut the bass in the stereo section through the internal high-pass circuit, connect a subwoofer via the SW terminal, and create a 2.1ch sound system that also produces plenty of low-frequency volume! Supports Bluetooth 5.0 input. Enjoy the best music wirelessly wherever you go!
