------------------------------------------------------------------------------------------------------------------ 【Voltage Compatibility】 When using electrical appliances, please note that they are designed for Japanese voltage specifications (90-110V), so if you use them with a different voltage, it may cause a malfunction. 【Plug Type】 Our products use Japanese plug types (A or B type). Please use a conversion adapter if necessary. 【Important Note on Transformers and Adapters】 A transformer adjusts voltage to match your device’s requirements. 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 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 not only in stereo 165W + 165W, but also in BTL mode, it becomes a 330W high-power monaural amplifier, allowing you to build the optimal system that matches the speakers you use. I usually combine it with a pair of passive speakers to create a 2.0ch Hi-Fi sound system, but if you need extra bass, you can switch the A300 to high-pass mode (you also need to switch to stereo mode) and use the internal high-pass circuit. Through this, the stereo section cuts the bass, connects a subwoofer with the SW terminal, and creates a 2.1ch sound system that produces plenty of bass! Compatible with Bluetooth 5.0 input. Enjoy the best music wirelessly anywhere!
