【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 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!
