USB DAC/Headphone Amp: The Audioengine D3 combines a USB DAC and
headphone amplifier for incredible audio performance in a portable design.
Simply connect the D3 to a free USB port on your Windows PC or Mac computer and
send high-quality music to your headphones or audio system. Setup is easy and no
special software is needed, making the D3 a true plug-and-play solution for
great audio sound from your laptop or computer.
24-Bit DAC: The Audioengine D3's premium AK4396 24-bit DAC (digital-to-analog
converter) allows you to bypass your computer's soundcard/headphone output and
send music directly through a USB digital connection for noticeably improved
fidelity and a higher output. The AK4396 DAC is well regarded for its low noise
and high fidelity. With it's high signal-to-noise ratio and low
distortion, the D3 delivers sound quality generally heard only in more expensive
Asynchronous USB Port: The D3 features a integrated male USB
(type-A) connector which plugs directly into a free USB port on you computer or
laptop. The D3's asynchronous data transfer carefully
controls USB streaming audio from any computer which greatly improves audio
performance. The D3 is powered directly from the USB port and power is passed
through two stages of regulation to ensure no USB 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.
Compatible Computers: The Audioengine D3 USB DAC/Headphone Amp is
compatible with Windows PC and Mac computers.
Supported Sampling Rates: D3 will process digital audio at any bit
depth up to 24 bits and any native sample rate to 96KHz. The D3 also has a
sample rate indicator that shows sample rates above 48kHz so you'll know you're
getting the most out of your HD music.
Headphone Amp: The D3's high-performance headphone amplifier
(LME49726) was designed for a wide range of headphones (10Ω-10,000Ω) and will satisfy even the most demanding
headphone enthusiast with its high output and revealing sound. The 3.5mm output
of the D3 connects to headphones, Audioengine powered speakers, or most audio
systems. The D3 also includes a 3.5mm-to-1/4" adapter for headphones which only
have a standard headphone jack.
Volume Control: Volume is controlled from your computer's OS and is
implemented in the D3 as a digitally-controlled analog volume control.
Compact Aluminum Design: The aluminum case of the D3 provides a rigid
chassis that prevents any unwanted interference. Thanks to its compact design,
the D3 can easily be taken where ever you go with your laptop.
