Questions & Answers

• Question:

  Where can I download drivers for the D3?

  Answer:

  The D3 is a USB Plug-and-Play audio device. This means that the drivers it uses are developed and provided by the developer of your computer's operating system. In the case of a Windows PC for example, these drivers are provided by Microsoft, and are a part of Windows.

• Question:

  How is volume controlled on the D3?

  Answer:

  The primary volume adjustment for D3 is the system volume. This interacts directly with circuitry in the D3 to control volume at the output. You can also use the volume control of your media player, but this (if implemented incorrectly) can potentially affect the digital signal out from your computer, so is considered less desirable.

• Question:

  Will D3 work with lower impedance headphones such as my Beyerdynamic DT-990 and Hifiman HE500?

  Answer:

  D3 can easily drive headphones with impedances as low as 10 ohms.

• Question:

  Is D3 USB input isochronous or asynchronous?

  Answer:

  The D3 is asynchronous, using dual clocking circuits to provide the greatest possible isolation between the system clock and the D3 DAC clock.

• Question:

  What media player software and audio file formats are compatible with the D3 when using it with a computer?

  Answer:

  When connected via USB with a computer, the D3 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.

• Question:

  Can I use the D3 with an Apple iPhone or iPad?

  Answer:

  Yes! You will need an Apple USB 3 camera adapter.  All you would need to do is connect the D3 and it's USB cable to the USB A port on the adapter and then the male lightning end of the Camera Adapter to your iOS device. You will also need to have a power supply power enough to power the D3 and your device.  Apple's USB C Fast charger is recommended.

• Question:

  Can I use D3 with the USB port on my TV, Airport Express, or other video device?

  Answer:

  Most of the USB ports on TVs and such are not meant for audio output, but serve other functions. As electronic components evolve, this may not always be the case. Check your operating manual for your device to see if the device supports USB audio. If so, the D3 may work, but as of late 2013 most of these ports do not support USB audio but are there for other reasons.
• Question:

  Can I connect the D3 DAC to a USB hub?

  Answer:

  Although D3 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.

• Question:

  Is there a recommended "break-in period" for the D3?

  Answer:

  Your D3 will sound great out of the box and will get better over time. We do generally recommend playing music for 40 to 50 hours before doing any critical listening, though.

• Question:

  Will the D3 work with USB 1.1?

  Answer:

  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.

• Question:

  How do I make sure that the D3 DAC is set to 24-bit/96KHz audio?

  Answer:

  If using a Mac, open the Audio MIDI Setup utility in Applications->Utilities, choose "Audioengine D3" under audio devices and check that the format is set to 96 and the bit depth is set to 24bit. Also a quick check is to simply observe the HD indicator on the D3 while music is playing. If the data rate of the digital signal being sent to the D3 is above 48K, then the HD indicator will be lit.

• Question:

  I'm having trouble using my D3 with Foobar in WASAPI and KS mode. What do I do?

  Answer:

  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.

• Question:

  How can the D3 external computer DAC improve my music?

  Answer:

  The D3 is essentially a very high end external sound card. Its components and implementation 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.

• Question:

  What are the QA Stickers?

  Answer:

  We take great pride in our products, and go through great lengths to ensure consistency and quality. For that reason, this item was randomly selected for an additional step of Quality Assurance.

• Question:

  Is it normal for my D3 to get warm/hot?

  Answer:

  It is normal for the D3 to be warm/hot to the touch as the outer case was designed to work as a heat-sink.

• Question:

  My D3 occasionally makes a clicking noise during playback. How can I avoid this?

  Answer:

  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 D3 is on a "High-Speed" bus and not a "Full-Speed" bus.
