Bring Great Sound Everywhere You Go

Now you can have the big sound you love when you listen to computer-based music and videos. Whether you are streaming at home or elsewhere, you can easily improve your listening experience with a 24-bit digital audio converter that bumps up the output while remaining faithful to the original sound.

Secure in a brushed-finish aluminum casing with a soft, protective carry case, the D3 can go with you anywhere. You can use your digital to analog audio converter for headphones or for other audio systems if you happen to have a crowd on hand. The D3 plugs right into the USB port on any computer without extra cables for power. The setup is prompt and doesn't require you to install software or mess with settings, so there is no waiting around for better sound.

Designed to Improve Streaming Audio on Computers

Your portable digital to analog audio converter lets you have the same sound experience on your computer as you have with other systems when you enjoy your music or videos. The D3 bypasses the computer’s output system to manage audio output through the USB port, bringing a rich portable sound presentation via asynchronous data transfer and compatibility with both high-performance and economy headphones.

Love Your Headphones All Over Again with Digital Audio Conversion

The digital audio converter (AK4396) inside the headphone booster is a tiny powerhouse that manages your sound using two-stage redundant power regulation and asynchronous data transfer with dual master clocks. The D3 can process digital audio at bit depths up to 24 bits and sample rates up to 192 kHz for clear, high-fidelity playback. The signal-to-noise ratio is enhanced by internally upsampling all bit depths to 24 bits.

That clarity is pushed out by the high-performance D3 headphone amplifier (LME49726), crafted to kick up the output level and fill your ears with song. The two-volt output is compatible with high-end and economy headphones with impedances as low as 12 ohms.

A Sound Booster That You Can Share

You can share the big sound with everyone else. As a portable interface, the D3 meets your needs for practical design that delivers surprising performance in a small package that is entirely mobile. Anywhere with analog audio inputs such as powered speakers or a stereo receiver will connect with the portable headphone amplifier to convert digital to analog sound. The computer operating system provides volume control, implemented as a digitally-controlled analog volume control.

Quality American Manufacturing

The D3 comes from Audioengine, the Texas-based manufacturer with a reputation for affordable quality. All aspects of the portable headphone amplifier are well built, from the internal components, to the metal injection molded aluminum case to the analog audio mini-jack, and comply with Mac or PC systems. Less costly than many digital audio converters, the D3 combines compact dimensions with high signal-to-noise ratio for portable sound quality that meets any standards.

What You Get When You Unpack

The 24-bit DAC With Headphone Amplifier comes with a ¼" headphone adapter cable, protective carry case, setup guide and product line brochure. Power cables are not necessary because the D3 is USB-powered with a low-noise power supply on a separate circuit board to manage heat and noise. 

You will notice big sound improvement immediately. However, the DAC will improve over 40 to 50 hours of break-in time, after which your sound satisfaction will be complete.
