【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: SMSL amplifiers use the NJW1194 electronic volume control chip from Japan's NJRC. This high-precision chip provides precise volume control and ultra-low distortion, ensuring pure, unaltered sound quality. Utilizing the latest BTL (Bridge-Tied Load) technology, the powerful amplifier ensures the highest quality, outstanding efficiency, and minimal energy consumption.
SMSL A300 Amplifier: The audio amplifier uses Infineon's new MA5332MS digital high-power amplifier chip, featuring high efficiency and low energy consumption. The stereo/mono amplification mode boasts a powerful output power rating of up to 165W at 4Ω load. Even at a high impedance load of 8Ω, the A300 generates 85W of clean power per channel, making the sound clearer, richer, and more textured.
Multiple Inputs: The Bluetooth amplifier supports RCA, USB, and Bluetooth 5.0 inputs. Wireless Bluetooth 5.0 reception provides better sound quality and a stable signal. The Bluetooth amplifier is suitable for connecting smartphones, tablets, and other devices. Numerous audiophile-grade audio components are used to improve subjective hearing.
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 adjustments make it easy to match different speakers and music. Built-in SMSL SDB patented sound and treble/bass adjustments give you unprecedented flexibility in matching this amplifier to different speakers and music types.
Desktop Audio Amplifier: Crafted from aluminum alloy and precision CNC-machined, the A300's shell features anodizing and chamfering techniques for a delicate finish. With its thoughtful design and practical features, the A300 is an audiophile's dream come true. Its user-friendly operating system is intuitive and easy to understand, and it also features a full-featured remote control for added convenience.
