Powerful USB digital interface: XMOS XU316, USB Audio Amplifier for PC

--Supports up to 32-bit/768kHz PCM and DSD512.

--Provide high-fidelity audio for PC and laptops, making up for the lack of power and audio quality of built-in sound cards.

--You can also experience playing music by connecting a USB flash drive via an extension cable.

High-efficiency heat dissipation design

The D3 PRO employs a highly efficient "integrated chassis cooling" design. Its core power amplifier chip, TPA3255, is directly and tightly connected to the heavy aluminum alloy casing, transforming the entire metal body into a giant passive heat sink. This rapidly and evenly dissipates heat with zero noise, ensuring stability and quiet operation during extended periods of high-power operation.

Intelligent Multi-Device Synergy

With just one HDMI cable connecting the TV and speakers, HDMI ARC/eARC technology allows sound to "return" from the TV to the speakers. Simultaneously, the CEC function enables one-button (interconnection/coordination) between the TV, speakers, game console, and other devices via remote control—pressing the power button on the TV remote turns all devices on simultaneously, adjusting the TV volume buttons directly controls the speaker volume, and the entire system automatically enters standby mode when powered off. From now on, you only need one remote in the living room to easily enjoy an immersive home theater experience, eliminating the hassle of switching between multiple remotes.
