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.

These applications provide bit-perfect playback and ensure that your DAC receives the correct sample rate without manual configuration.

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.

Step-by-Step Guide

1. Open Terminal:
   • You can find Terminal in your Applications folder under Utilities, or you can use Spotlight by pressing Cmd + Space and typing "Terminal".
2. Execute the Command:
   • In the Terminal window, type the following command and press Enter:

bash

Copy code

sudo pkill bluetoothd

3. Enter Your Password:
   • After pressing Enter, you will be prompted to enter your password. Type your Mac's administrator password and press Enter.
   • Note that when you type your password, it won't be displayed on the screen (not even as asterisks). Just type it and press Enter.

By following these steps, you should be able to reset your Bluetooth service on your Mac, which can help resolve connectivity issues with your Audioengine devices or any other Bluetooth peripherals.

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.

If you do not have headphones connected to the DAC3, the LED light will turn off after cycling through 'Blue/Green/Red'.  This is an intended feature to help save device power when headphones are unplugged.

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.

Check the cables between DAC3 and your headphones or sound system. Also check your audio player and OS audio controls to ensure that the audio balance is centered as well.

Please check that the volume control on your phone/tablet/computer is up and at a good level; 75% should be a good level. Also try adjusting the volume on the DAC3 as well.

1. Verify that one of the included cables is completely plugged into the DAC3 and your source device.
2. Also verify that a 3.5mm mini-jack is firmly plugged in.
3. Try disconnecting and reconnecting both the USB and 3.5mm cable.
4. You will see an LED light confirming the DAC3 is getting power and is connected to an output.
5. Check the volume level on your source.
6. If connected to a computer, verify that the DAC3 is recognized and the active output device.
7. Try restarting your computer.

If none of the above helps resolve your issue, please contact our Support Team for additional assistance.

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

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

Yes! All you would need to do is connect your iOS device to the DAC3 using the included Lightning to USB-C cable.

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!

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.

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.

The DAC3 includes a headphone amplifier based on the ES9281A PRO Ultra DAC delivers 32-bit precision, high dynamic range and ultra low distortion. This headphone amp is able to provide low-impedance, high-fidelity audio to a wide range of wired headphones.
