USB Powered Audio
USB port provides 2.5W output power (5V 500mA). While playing music, the average power is usually only 1/8 of the peak power. If the amplifier is limited to 2.5W to ensure a low distortion during peak power output, the volume will be too low to provide an enjoyable listening experience. If the average output power is set at about 2.5W, the amplifier will display excessive distortion during peak power output, causing the listening experience. Our USB Powered Audio Amplifier employs high-efficient DC-DC converter and battery to manage the energy flow of the USB port, realizing intelligent power storage and release. Together with the integrated Class D amplifier, it provides you a pleasant rich listening experience.
High-efficient DC-DC Converter and Class D amplifier.
The Combination of high-efficient DC-DC converter and Class D amplifier greatly improves the power efficiency, using every bit of the precise 2.5 W output from the USB port to provide a crystal clear sound.
Environmental friendly with Intelligent Power Management
The system will store the surplus energy and pass it to the amplifier during peaks.
If the power demand exceeds the maximum power output of the USB port, the stored energy provides the peaks, ensuring an uninterrupted perfect music experience.
No power adapter necessary just plug to your computer or MP3 player and enjoy a rich listening experience.
