D1 USB

The D1 utilizes the TI1020B USB controller, widely recognized as a standard for higher-end USB audio products. The D1 is powered directly from the USB bus and USB power is passed through two stages of regulation to ensure high stability and low noise.

D1 DAC

The D1 uses the AK4396 DAC, 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 D1 presents impressive low noise and low distortion characteristics.

D1 Headphone

The D1 includes a headphone amp based on the TI OPA2134 low noise opamp. This headphone amp is able to provide low-impedance, high-fidelity audio to a wide range of headphones and supports headphones with impedance as low as 20 ohms.

I have the original Audioengine 5 (not the A5+), will the D1 / D2 DAC work with the inputs on that original model?

You can use Audioengine DACs with your original A5s, no problem. You would simply use a standard RCA cable and the RCA to mini-jack adapter that came with the A5 to connect the RCA output from the DAC in to one of the mini-jack inputs.

How can the D1 external computer DAC improve my music?

The D1 is essentially a very high end external sound card. Its components and implementation of those components make it more capable than what might be built in to a computer, not to mention the benefit of moving those sensitive components external to the potentially noisy interior of your computer. All of this means the signal your speakers receive will be clearer, with a lower noise-floor, and with a more pronounced dynamic range over your internal sound card.

How easy is it to set up the D1?

Connect the included USB cable from your computer to the D1. If using a Mac, go to System Preferences/Sound, and select "Audioengine D1". If you're using a PC, no setting changes are needed as the computer will automatically find the USB driver. Now play music from iTunes or your favorite media player and that's it - setup really is that easy.

Are the RCA connections on the rear of the D1 fixed or variable?

These RCA outputs are variable, adjusting the volume on the D1 will adjust the output of any speakers or amp connected to this output. This makes the D1 a handy way to control the volume of both your speakers AND headphones.

Is D1 USB input isochronous or asynchronous?

The D1 is asynchronous, which means it controls the data streams timing using it's own internal clock to minimize jitter.

How do I find out more information about DACs and computer audio?

There are some excellent online computer audio forums and a quick search will turn up everything you need to know about the best hardware and software and how to get started on any budget. Computer audio is quickly evolving so we suggest to check and make sure the information you find is up to date.

When I plug in headphones will the D1 RCA outputs be muted?

Yes, the output will mute and audio will only play through your headphones.

What is the best USB cable length to use with D1?

The maximum length USB cable you'll be able to use with good results will vary based on your computer's USB port, and the type of cable being used. Some USB ports perform better than others, so be sure to try them all. For the best results, we generally recommend a maximum length of around 3 ft (~1m) and a cable that's USB 2.0 or 3.0 certified - or built specifically with audio in mind.

Can I connect the D1 DAC to a USB hub?

Although D1 may work just fine when connected to most USB hubs, this is not recommended as the data rate may not be fast enough for higher-resolution music. We therefore suggest you select a high-speed USB bus all by itself and don't use a USB port on your keyboard, for example.

Will the D1 work with USB 1.1?

Yes, however, note that 24/96 HD digital audio pushes the limits of USB 1.1 speeds. Due to this it's highly recommended that you connect to a higher-speed USB 2.0 port.

How do I use the optical input of the D1?

Connect an optical cable and the D1 will sense that an optical input is present and give that input priority. If using D1 with optical outputs from your TV, DVD play, Apple TV, etc you will need an AC USB power adapter (sold separately) to power D1. When using the optical output from your computer, you may power D1 via the computer's USB power and therefore no external power supply is needed.

The D1 is connected to the optical output of my TV but I'm not getting any sound. What can I do?

In your TV menu verify that "PCM STEREO" is selected and "DOLBY DIGITAL" is off.

How do I make sure that the D1 DAC is set to 24-bit/96KHz audio?

If using a Mac, open the Audio MIDI Setup utility in Applications->Utilities, choose "Audioengine D1" under audio devices and check that the format is set to 96 and the bit depth is set to 24bit.

I'm having trouble using my D1 with Foobar in WASAPI and KS mode. What do I do?

In the Foobar control panel, under Preferences->Output, set the buffer length to minimum. A few customers have mentioned that WASAPI mode is more stable when used under WinAmp, so try that as well.

Is there an easier way for Mac users to get to System Preferences and the Audio MIDI Setup control panels?

A customer recommended an app called Soundsource - http://rogueamoeba.com/freebies - which is an easy way to switch between audio input and outputs as well as to access System Preferences and the Audio MIDI control panels.

Will the D1 work with my low-impedance HiFiMAN HE-500 headphones?

The D1 includes a headphone amp based around the TI OPA2134 low noise opamp. This headphone amp is able to provide low-impedance, high-fidelity audio to a wide range of headphones and supports headphones with impedances from 20 to 300ohms.

Is there a recommended "break-in period" for the D1?

Your D1 will sound great out of the box and will get better over time, however, it's best to play music for 40 to 50 hours first before doing any critical listening.

Why do I lose system volume control when using the D1 with my computer?

Optical and USB outputs are all digital, so both Windows and Mac OS X will disable the system volume control when they are in use. You can still control the volume directly in iTunes (or any media player), with the front panel volume control on the D1, or with the volume control on your audio system.

My D1 occasionally makes a clicking noise during playback. How can I avoid this?

Try removing all other USB devices temporarily, and try each USB port on your computer one at a time to see which one works best in your setup. USB audio needs quite a bit of bandwidth, so for best results ensure your D1 is on a "High-Speed" bus and not a "Full-Speed" bus.

What media player software and audio file formats are compatible with the D1 when using it with a computer?

When connected via USB with a computer, the D1 acts like a USB sound-card. Because of this, once it's set as your default playback device, it should work with any application on your computer playing audio, and with any file format the software supports.

Can I use the D1 with my Airport Express for even better sounding Airplay?

Absolutely! We've had a lot of really good feedback from our customers on this, and its really easy to add to an existing Airplay setup. You can connect your Airport Express into the D1s optical input using a mini-Toslink to Toslink cable to pass a digital signal to the D1. Like other setups without a computer you'll still need to connect the D1 to a USB connection for power - Either a USB AC adapter like we offer in our accessories, or a nearby USB port capable of delivering a minimum of 500mA. Please note that the USB port on the Airport express is intended only for lower powered or self powered devices (like a printer) and will not reliably power the D1.

D1 Troubleshooting Tips


General
  • Try restarting your computer and testing your D1 again to see if this helps.
  • Make sure the USB and audio cable connections to and from the D1 are complete and verify that these cables are in working order. We recommend using the USB cable included with your D1, however, if you are using another USB cable, make sure it is no longer than 3 ft (1 meter).
  • Remove all other USB devices temporarily from your computer to see how this affects the D1 playback. Audio over USB and bus powering a device can both be somewhat demanding. USB ports can share a bus internally and can also share their bus with devices internally as well.
  • Because of this some ports may not perform as well as others, so be sure to try each port one at a time.
  • It is important to note that the USB audio input will only work with a computer. If you are using your D1 with a different device the USB connection is only used for power.
  • When using the optical input on your D1 be sure your source (computer, TV, CD / DVD player, etc) is set to PCM Stereo output and not Dolby Digital, DTS, etc.
  • If you are using any wireless devices in line with your D1, please remove the wireless device from the application (temporarily) and connect the D1 directly to the source.
  • Test your D1 with a different computer/setup at a different location, maybe at a friend or relative's house. This would help to verify if there is something wrong with the D1 or something else in your setup that is causing this issue.

Mac
  • Try a NVRAM/PRAM reset. This resets the system configurations for some audio and video related settings and can many times help clear up problems related to audio. See the link below from Apple’s support page for information on how to do this. http://support.apple.com/kb/ht1379
  • Use different Bit Depths and Sample rates. On a Mac these settings are under Applications ­­> Utilities ­­> Audio MIDI Setup. Try using both 16 bit as well as 24 Bit.
  • Test a different media player (iTunes, Songbird, WinAmp, Cog, etc) and file types (MP3, ALAC, FLAC, etc). If your media library is located on an external drive or network attached storage, please try playing audio files located on your internal hard­drive.

Windows
  • Try letting windows reinstall the D1’s device driver. You can find instructions from Microsoft on how to reinstall a plug and play device like the D1 for Windows in the link below. http://technet.microsoft.com/en-us/library/cc725782.aspx#bkmk_2
  • Use different Bit Depths and Sample rates. In Windows 7 you can get to these settings by right clicking on your volume icon in the system tray and selecting "playback devices", then double click the "Speakers ­ Audioengine D1" dialog, now you'll find these under theadvanced tab of the "Speakers Properties" window. Try using both 16 bit as well as 24 Bit on a variety of sample rates to see how this affects your audio playback.
  • Test a different media player (Windows Media player, Foobar2000, iTunes, WinAmp, etc) and file types (MP3, ALAC, FLAC, etc). If your media library is located on an external drive or network attached storage, please try playing audio files located on your internal hard­drive.
  • Sometimes other devices in your system including built in devices don't play nice with audio over USB. For more advanced users running the linked application may help to diagnose what components or drivers may be causing problems. http://www.thesycon.de/eng/latency_check.shtml
If the problem persists please provide us with the results of your troubleshooting. Please also include the date, purchase location, and serial number for warranty purposes. If you live outside of the continental US you will need to contact your dealer or our distributor in your country for further assistance.
