Hear The Difference
Powerful Yet Portable
The Audioengine D3 Premium 24-bit DAC (digital to analogue converter) allows you to bypass your computer’s headphone output and send music directly through USB for improved fidelity and a higher volume output. The D3 is a powerful yet portable converter with performance and features usually found in more expensive DACs.
D3 is the perfect interface between your computer and headphones or any music system.
Why You'll Love It
- Stream bit-perfect 24/96 HD audio
- Drives even the most-demanding headphones
- Computer OS volume control
- HD sample rate indicator
Set Up In Seconds
Simple. No Hassle. Easy to Use.
Setup is easy and no special software or driver is needed, making D3 a true plug-and-play solution.
The D3 plugs directly into a USB port on your computer so no external power supply or cables are needed. The output of the D3 connects to headphones, Audioengine powered speakers or any audio system. The D3 has a sample rate indicator that shows sample rates above 48K so you’ll know you’re getting the most out of your HD music.
High Quality Sound
For the Demanding Headphone Enthusiast
D3 DAC will process digital audio at any bit depth up to 24-bits and any native sample rate to 96KHz.
With its high signal-to-noise ratio and low distortion, the D3 delivers sound quality generally heard only in more expensive DACs.
The high-performance headphone amplifier was designed for a wide range of headphones. The D3’s asynchronous data transfer carefully controls USB streaming audio from any computer which greatly improves audio performance.
D3 will satisfy even the most demanding headphone enthusiast with its high output and revealing sound.
Ready for Anything
Computer to Headphones or Any Music System
The quality of most computer headphone outputs isn’t generally very inspiring, so the D3 provides a better option by streaming audio from your computer’s USB port and directly connecting to your music system or headphones.
D3 includes a USB DAC and a carefully selected headphone amplifier for incredible audio performance in a super-compact design.
The D3 DAC is the perfect way to get great-sounding music not only from your computer to headphones but also from your computer to any music system.
D3 Internal Converter
The heart of the D3 is the AK4396 DAC, which is well-regarded for its low noise and high fidelity. Due to the high signal-to-noise specs of the AK4396 and the added benefit of double redundancy power source conversion and filtering, the D3 presents impressive low noise and low distortion characteristics. The D3 can process digital audio at any bit depth up to 24 bits and any sample rate up to 192kHz. D3 pads (upsamples) all bit depths internally to 24-bits, thus achieving a higher signal-to-noise ratio.
D3 Headphone Amplifier
The D3 contains a high-performance headphone amplifier based on the LME49726 low-noise opamp. This amp is able to provide low-impedance, high-fidelity audio and a 2-volt output which easily drives a wide range of headphones, satisfying even the most demanding headphone enthusiasts. The D3’s relay-controlled stereo output can also be connected to any system with an analogue audio input, such as Audioengine powered speakers.
The D3 is powered directly from the USB bus and power is passed through two stages of regulation to ensure no USB bus power variations affect the audio quality. This low-noise, low-ripple power supply is located on a separate circuit board for extra isolation and thermal management.
