  2. Connect the wireless antenna to the HD3 rear panel.
  3. Verify that the volume/power knob on the front panel of the left speaker is in the OFF position by rotating the knob counterclockwise until it clicks off.
  4. Connect the cable from the external power supply unit to the left speaker rear panel.
  5. Connect the power cord to the other end of the power supply and plug the cord into a functioning power outlet. A light on the power supply should now be illuminated.

Wireless connection

  1. Turn power on via the front panel volume/power knob.
    HD3 will automatically go into Bluetooth “pair mode”and the Power/Pair button on the HD3 front panel should start flashing.
  2. On your device (phone, tablet, laptop, etc) turn on Bluetooth and go to Bluetooth preferences.
  3. Select”Audioengine HD3″ to pair and connect. The Pair indicator light on the HD3 front panel should be solid.
  4. Play your music and adjust volume levels for HD3 and your device.
    To add additional devices put HD3 back into pair mode by discon-necting HD3 from your device or by pressing and holding the Pair button on the HD3 front panel until the pair indicator starts flashing. HD3 can wirelessly connect to only one device at a time, however it will remember up to six different devices.

Wired connection

  1. Connect an audio cable (mini-jack or RCA) between your device and one of the inputs on the HD3 rear panel.
  2. Play music and adjust the volume on the speakers and your device to your desired listening levels.

USB audio connection

  1. Connect the included USB cable between an open port on your computer and USB input on the rear panel of the left powered speaker.
  2. If using Windows, the HD3 should be recognized automatically. For Mac, under System Preferences/Sound/Output, select”Audioen-gine HD3″

As HD3 includes built-in power amplifiers do not connect the HD3 speaker terminals directly to the speaker outputs of a stereo receiver or amplifier.

Inputs and volume settings

Multiple sources and devices may be connected to the speakers at the same time and all inputs are open and active so it’s easy to switch between your tablet, phone, TV, or any other device.

To adjust the volume, we recommend you first set a level on HD3 and then use the volume control directly on your device to adjust the overall level. Volume settings are flexible and there is no right or wrong so feel free to experiment to find volume levels that work for you.

Other Features

Variable audio output
The HD3 includes a variable full-range preamp audio output so you can connect a subwoofer, other Audioengine powered speakers, or wirelessly stream music to other systems around your house using an Audioengine wireless adapter. This output is variable (adjustable) so the volume level of the output can be controlled from the HD3 front panel.

Break-in period
Your HD3 speakers will sound great right out of the box and will sound even better over time. However, it’s best to give them 40 to 50 hours break-in time before doing any critical listening.

We don’t recommend using any solvents or cleaners on Audioengine cabinets or speakers. Just wipe down with a soft, dry cloth.
