【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. Volume Control and BTL: The SMSL amplifier uses NJW1194 electronic volume control chip from Japan's NJRC company. This high-precision chip provides precise volume control and ultra-low distortion, ensuring pure, unaltered sound quality. A powerful amplifier that utilizes the latest BTL (Bridge-Tied Load) technology to ensure the highest quality, outstanding efficiency and minimal energy consumption. SMSL A300 Amplifier: The audio amplifier uses Germany Infineon's new digital high-power amplifier chip MA5332MS, which has high efficiency and low energy consumption. Stereo mono amplification mode has a powerful output power rating of up to 165W into a 4Ω load. Even with an 8Ω high impedance load, the A300 produces 85W of clean power per channel. Makes the sound clearer, richer, and richer in texture. Multiple input terminals: Bluetooth amplifier supports RCA, USB and Bluetooth 5.0 inputs. Wireless Bluetooth 5.0 reception, better sound quality, stable signal. Bluetooth amplifier is suitable for connecting smartphones, tablets and other devices. A number of audiophile-grade audio components are used to improve subjective hearing. Can form a 2.1 audio system: A dedicated subwoofer signal pre-output makes it easy to connect an active subwoofer to form a 2.1 system.
