Wireless Audio Sender Wireless Audio Receiver (1) Power adapter (1) RCA adapter “Y” cable (2) Mini-jack (3.5mm) audio cables S etup Guide Your W3 components are not water-resistant, so it's important that they should be kept fr ee of moisture. You should clean only with a dry cloth or tissue and no liquid cleaners or solvents should be used. Welcome to the Audioengine family and congratulations on your purchase of the Audioengine W3 Premium Wireless Audio Adapter! The Audioengine team is dedicated to bringing you the highest-quality listening experience possible and the W3 was designed with the same attention to detail and operational simplicity as other Audioengine products . Our goal is to get you to your music as quickly as possible, without all the “gadget tinkering” that so many other products require. We wish to thank our customers, distributors, and resellers for helping us cr eate another quality Audioengine product. Easy setup - connects in seconds Works with Mac or PC - or without a computer Plug-n-play - no software or downloads to install Super-compact size, no batteries required P la ys all music formats from any media player 100 ft (30m) typical range with no signal delay, dropouts, or interfer ence CD-quality,16-bit stereo sound with no added compression Replaces any RCA or mini-jack (3.5mm) audio cable which is an inexpensive way to set up a high-quality, whole-house wireless music system. The W3 set consists of 2 dongles, the Sender and Receiver. The W3 Sender connects to your computer (or any audio source) and transmits stereo sound automatically to the W3 Receiver. The Receiver can be connected to any gear with an analog audio input, such as powered speakers, a boombox, stereo system, subwoofer, etc. You can mix- and-match different Senders and Receivers, broadcast to up to four W3 Receivers or "daisy-chain" multiple sets, Power for the devices is provided fr om a USB computer port for the Sender, from the included power adapter, or any adapter with a USB connector, such as an iPhone charger, for example. Another power source for the W3 Receiver is the Audioengine 5+ powered The Sender and Receiver dongles look identical however you can tell them apart by these markings: The end of each unit has an audio input or output con- nector, shown with these symbols: 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+ power ed speakers or any audio system. There are many ways to use the W3 Premium Wireless Audio Adapter . Some possible configurations ar e listed here and a few specific examples ar e shown in the Configuration section. These ar e by no means all the possible uses - they ar e just shown to give ideas for your own setup. Shown here are examples of some common W3 wireless configurations and setup instructions for each: 1 Computer USB Audio to Powered Speakers 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 fr om 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 ar e 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. 2 Computer to any Audio System …
