Get fantastic sound from your digital audio sources
How do you get sound from your PC? If you're still doing it the old fashioned way, by plugging into your computer's headphone jack, then you should definitely know about the Audioengine D1. This tiny, outboard digital-to-analog converter simply connects to one of your PC's USB ports, and bypasses your computer's built-in audio circuitry.
By processing your digital music files outside the noisy environment of your computer, you'll hear far more dynamic and detailed sound that you can really savor on your headphones, powered speakers, or stereo system. The D1 also includes an optical digital input so you can enjoy similar improvements in sound with your old CD player, network music streamer, set-top box, game console, or almost any other audio device with an optical digital output.
Make your headphones sing
The plug-and-play D1 delivers sparkling clear sound from your computer to your headphones, stereo system, or powered speakers (Audioengine A2 speakers shown
A pair of good headphones can give you a real taste of high-end audio without breaking the bank. But you're unlikely to find high-end sound coming out of your headphones if you plug them straight into your laptop. That's because most computer manufacturers use low-cost, low-performance circuitry to power their headphone jacks. The headphone amp inside the D1 will quickly spoil you. It delivers richer, deeper bass and clearer highs while revealing layers of musical detail that ordinary headphone jacks obscure.
Easy plug-and-play operation
Adding the D1 to a system is simple — just plug it into any USB port on your computer, where it will install itself and be ready for use in a matter of seconds. From there, just plug in your 'phones, or connect the preamp outputs to your powered speakers or stereo and you're done. The handy volume knob lets you control listening levels for both headphone and preamp outputs.

More details on the Audioengine D1
Overview: The D1 DAC (Digital to Analog Converter) is designed to connect between your computer's USB port or an optical digital output, and your audio system or headphones. It can also be used as a portable DAC (soundcard) with a laptop computer. The two signal inputs are a USB Type-B port (USB Type-A to USB Type-B cable included) and an optical digital (Toslink) jack. There are two outputs, rear panel analog stereo RCA jacks and a front panel 3.5mm headphone jack. Both outputs are controlled by the rotary volume knob on the front panel and the RCA outputs are muted when headphones are plugged into the front panel mini-jack output. The small switch on the front panel lights when the D1 is turned on.
Note: If connecting to a television set's optical output, please make sure that you are able to select PCM as the default optical out audio format from your television's Audio menu. This DAC is not compatible with multi-channel audio signals and will not work with televisions that do not output PCM.
