Setup is really simple. The W3 Sender needs power and an audio input (either USB audio or audio into the mini-jack input on the end of the Sender). The W3 Receiver also needs power and a place to send the audio to, such as Audioengine 5+ powered speakers or any audio system.


There are many ways to use the W3 Premium Wireless Audio Adapter. Some possible configurations are listed here and a few specific examples are shown in the Configuration section. These are by no means all the possible uses - they are just shown to give ideas for your own setup.



Shown here are examples of some common W3 wireless configurations and setup instructions for each:


Note: If using Audioengine 5+ (A5+) powered speakers the A5+ USB power port can be used to power the W3 Receiver.

  1. Connect the W3 Sender to your computer's USB port.
  2. For PC wait for the USB audio connection to be detected. For Mac OS, open System Preferences/Sound, select Output, then select “Audioengine W3”.
  3. Connect the W3 Receiver to the included power adapter and plug the adapter into a power outlet.
  4. Connect a mini-jack or RCA audio cable from the W3 Receiver to your powered speaker’s audio input.
  5. The status indicators on the Sender and Receiver will blink briefly and then go solid, indicating that they are paired.
  6. Play your music!

Note: If using W3 for USB computer audio there is no need to connect an audio cable from the W3 Sender to your computer's headphone output. Doing so may create a ground loop resulting in unwanted noise.


  1. Follow steps 1 thru 3 above.
  2. Connect the included RCA “Y” adapter interface cable to the W3 Receiver audio output.
  3. Connect an RCA cable (not included) from your stereo receiver's RCA inputs to the RCA “Y” adapter.
  4. The status indicators on the Sender and Receiver will blink briefly and then go solid, indicating that they are paired.
  5. Play your music!

Note: If you have Audioengine 5+ powered speakers, you may use the built-in USB power/charge port on the A5+ to power the W3 Receiver. Otherwise, you can use an iPhone charger or purchase an extra Audioengine power adapter.

  1. Connect the included mini-jack cable from your iDevice to the W3 Sender audio input.
  2. Connect the W3 Sender to the included power adapter and plug the adapter into a power outlet.
  3. Connect the included mini-jack cable from the W3
  4. Connect the W3 Receiver to another power adapter (1 power adapter is included, others sold separately).
  5. Plug the power adapter into an AC outlet.
  6. The status indicators on the Sender and Receiver will blink briefly and then go solid, indicating that they are paired.
  7. Play your music!

  1. Connect the W3 Sender and W3 Receiver to power adapters and plug each into a power outlet.
  2. Connect your surround sound AV receiver’s rear channel (or subwoofer) RCA outputs to the W3 Sender input.
  3. Connect the W3 Receiver to your powered rear channel speakers (or subwoofer).
  4. The status indicators on the Sender and Receiver will blink briefly and then go solid, indicating that they are paired.
  5. Play your music!

Note: To set up wireless rear channel speakers AND a wireless subwoofer from your surround system, simply add another W3 Sender/Receiver pair and repeat the previous instructions.
