The Audioengine D3 audio converter connects to a USB port and converts the digital signal to analog, bypassing the computer’s sound card. It supports audio up to 24-bit with a native sample rate of up to 96 kHz, using asynchronous dual-clock USB data transfer. The sample-rate indicator lights up for rates above 48 kHz.

The 3.5 mm mini-jack analog output connects to headphones, powered speakers, or another audio system. The built-in headphone amplifier is recommended for headphones with an impedance of 10 Ω to 10 kΩ, while the enclosure is made of aluminum. The USB connection requires no external power supply or special software.
