Questions & Answers

• Question:

  I am playing HD files or streams but the DAC3 HD indicator LED is not illuminated.

  Answer:

  Verify that the sample rate selection in your computer's OS is set correctly. Your OS's output settings will determine the color of the LED on the DAC3 -- not the specific file being played.

  Audioengine HD3 - Hi-Fi Stereo Desktop Speakers w/ Built-in 10K OHM Headphone Amplifier

  Reddit R/Headphones

  "The HD3 features a PCM5102 DAC and a OPA2134 headphone amp that's separate from the main speaker amp...The 3.5 mm headphone output does exactly what it's supposed to do: power your headphones without coloring the sound.

  There was no noticable hiss or distortion at either end of the volume range. All you get is clean power with no coloration.

  At $399 -- $319 refurb -- the HD3 is an awesome value that rolls 2 channel powered speakers, a DAC, a headphone amp, and Bluetooth receiver all into compact and attractive package."

  DAC3 Internal Converter

  The heart of the DAC3 is the ES9281A PRO DAC, which is well-regarded for its low noise and high fidelity. Due to the high signal-to-noise specs of the ES9281A PRO and the added benefit of double redundancy power source conversion and filtering, the DAC3 presents impressive low noise and low distortion characteristics. The DAC3 can process digital audio at any bit depth up to 32 bits and any sample rate up to 192kHz. DAC3 pads (upsampled) all bit depths internally to 32-bits, thus achieving a higher signal-to-noise ratio.

  DAC3 Headphone Amplifier

  The DAC3 contains a high-performance headphone amplifier based on the LME49726 low-noise opamp. This amp is able to provide low-impedance, high-fidelity audio and a 2-volt output which easily drives a wide range of headphones, satisfying even the most demanding headphone enthusiasts. The DAC3’s relay-controlled stereo output can also be connected to any system with an analog audio input, such as Audioengine powered speakers.

  DAC3 Power

  The DAC3 is powered directly from the USB bus and power is passed through two stages of regulation to ensure no USB bus 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.

  DAC3 Volume Control

  Volume for headphones and line-out is controlled directly from the DAC3 side panel. Smoothly adjust volume levels at fine increments without any undesirable noise or channel imbalance at lower volumes.

• Question:

  How do I know if I bought from an authorized and legitimate site?

  Answer:

  Audioengine operates two websites, audioengine.com and audioengineeu.com. If you go to any other site but these, they are not an Audioengine site. For Canada, Mexico and most of Europe and the UK, we only sell through Amazon. There are also a host of authorized retailers and sites across the US, and they can be found here. For international sales, we have distributors that operate independently, and they can be found here. 

  What happens if I buy from an authorized site claiming to be Audioengine? Unfortunately, there is not much we can do. We are taking all the action we can to make sure those sites don't get indexed, but we recommend you work with the provider of the card you used to make payment to get your money back.

  What DAC chip does the DAC3 use?

  Answer:

  The DAC3 uses the ES9281A PRO DAC chipset

  The DAC3 only needs 200mA USB power to work, which most all modern source devices are capable of.

• Question:

  A hum or buzzing sound can be heard.

  Answer:

  Verify that the audio cable from the D3 is plugged in and in working order.
• Question:

• Question:

  Does DAC3 support MQA files?

  Answer:

  Yes! DAC3 offers broad support for standard hi-res audio formats including MQA, PCM and DSD.

• Question:

  Will DAC3 work with lower impedance headphones such as my Beyerdynamic DT-990 and Hifiman HE500?

  Answer:

  DAC3 can easily drive wired headphones with impedances of 12 ohms or higher.

• Question:

• Question:

  How can the DAC3 external computer DAC improve my music?

  Answer:

  The DAC3 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 into a computer, not to mention the benefit of moving those sensitive components outside and away from the potentially noisy interior of your computer. All of this means the signal your speakers or wired headphones receive will be clearer, with a lower noise-floor, and with a more pronounced dynamic range over your internal sound card.

• Question:

  Can I connect the DAC3 to my Android device?

  Answer:

  The DAC3 will work with Android or any device that can operate as a USB-C host, can provide enough power via USB, and includes generic drivers for standard USB audio playback.  A device with Android 5.0 or later should have both USB host mode and native plug-and-play functionality for USB audio, so you could connect the two together using the included USB-C cable.

• Question:

  How easy is it to set up the DAC3?

  Answer:

  To get things up and running only takes 3 simple steps. You would just need to first connect the included USB-C cable from your device's USB port to the DAC3; then you'll need to connect the mini-jack output of your DAC3 to headphones, or any audio input of your powered speakers, stereo system, etc.

  Next, if using a Mac, you will need to go to System Preferences/Sound, and select "Audioengine DAC3"; if you're using a PC, no setting changes are needed as the computer will automatically find the USB driver. Finally, you'll just need to adjust the volume on your device and DAC3 to medium and you’re ready to play music from iTunes or your favorite media player and that's it! Setup really is that easy!

  
  
  

• Question:

  Are firmware updates or driver downloads needed for my Audioengine product?

  Answer:

  No, there are no firmware updates or special drivers needed unless you own our A1-MR multi-room speakers or our B-Fi multi-room wireless streaming device.

  If a firmware update is released for the A1-MR or the B-Fi, you will be notified of the update the next time you open the Audioengine Control App.  If an update is needed, simply click "update" on the DEVICES page next to the product that needs to have the firmware update applied.  The app will handle the rest of the process from there!

  Standard plug-n-play drivers that are provided by your computer's OS are utilized when using the USB input on our A2+, HD3, and HD4 speaker models.

  And all of our Bluetooth speakers/products are compatible with any device that supports Bluetooth, and the A2DP profile for streaming stereo audio. This includes most smartphones, tablets, and computers. For computers that don't include Bluetooth support out of the box, you can simply add a USB Bluetooth adapter.
