【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.
[About clocks that synchronize time via radio waves]
The function of clocks that synchronize time via radio waves only works in the Japanese area. Please be careful.
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. The 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, 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. Eight preset EQ options and treble/bass adjustment make it easy to match with different speakers and music. Built-in SMSL SDB patented sound and treble/bass adjustment gives you unprecedented flexibility when matching this amplifier to different speakers and music types.
Desktop Audio Amplifier: Made from aluminum alloy and precision CNC machined, the A300 shell has anodizing technology and chamfering, creating an exquisite finish with a delicate touch. With its thoughtful design and practical features, the A300 is an audiophile's dream come true. The user-friendly operating system is intuitive and easy to understand, and includes full-featured remote control capabilities for added convenience.
