Our take on the Audioengine W3

by Dave Bar
Audioengine

Send wireless audio to your sound system

The Audioengine W3 lets you make a convenient wireless connection between any two components where you'd normally use a stereo RCA or mini patch cable. This two-part system includes a powerful wireless Sender and a companion Receiver. Connect the Sender to your portable music player via the included stereo minijack cable, or plug it into your computer's USB port. Then connect the Receiver's stereo minijack output to your audio system or powered speakers.

Powered by USB — one adapter included

Both the Sender and Receiver are powered via their USB connections. One AC-to-USB power adapter is included in the package. This is perfect when you're using the system to send audio from your computer, because the Sender can get its power from the USB port. It's also perfect when using the system to wirelessly connect your music source to the Audioengine A5+ powered speakers, which feature a handy back-panel USB power output. Other AC-to-USB power adapters — such as the one that comes with most iPods® — can be used for applications where you need two adapters.

Unparalleled sound quality and versatility

The W3 can pass CD-quality sound with no loss in audio fidelity, so you can enjoy your music in full detail — just like you would with a wired connection. The transmitter has an effective range of 100 feet, so you'll get a strong signal not only across the room, but across your home as well. And this versatile system can also be used in other applications. For example, pair the W3 and your compatible home theater receiver with Audioengine's A2 compact powered speakers to make a wireless rear speaker setup for your surround sound system. Or use it to create a wireless subwoofer. With the W3 Sender's ability to transmit to multiple receivers, you can even have multiple subwoofers to add more boom to your room.

Features

Overview: The Audioengine W3 is a 16-bit wireless system that is designed to connect your audio components wirelessly. The W3 handles USB audio, up to 16 bits/48KHz with no compression, as well as analog audio via a 3.5mm minijack. The W3 kit includes a Sender (transmitter) & Receiver; the system is designed to deliver an audio signal wirelessly between two components. This system will work in many different applications, including (but not limited to) a computer sending audio to powered speakers, a computer sending audio to a stereo or A/V receiver, an iPod or other portable player sending audio to the Audioengine 5+ powered speakers (the A5 is specifically mentioned here because it has a USB port to power the W3 Receiver), and an A/V receiver sending audio to powered surround or second zone speakers.

Note: The W3 is natively compatible with Windows 2000/XP/Vista/7/8 and Mac OSX. There are no drivers or software to install.

Two Part System: The W3 consists of 2 parts, the Sender & Receiver. The Sender transmits audio from your computer through USB audio or from any product with a 3.5mm minijack or RCA audio output. The other end of the W3, the Receiver, delivers audio to any product with minijack or RCA audio connectors.

  • Sender: The W3 Sender is powered through its USB plug; one USB AC power adapter is included with the system to power either the Sender or Receiver. If not powered by the included adapter, the Sender can be powered by a computer, iPod power supply, or numerous other USB power supplies currently available. The audio input is a 3.5mm stereo minijack. When used with a computer, the Sender acts as a sound card and receives its audio input through the USB port, so no connection to the minijack is necessary.
  • Receiver: The W3 Receiver is powered through its USB plug; one USB AC power adapter is included with the system to power either the Sender or Receiver. If not powered by the included adapter, the Receiver can be powered by Audioengine A5 powered speakers, an iPod power supply, or numerous other USB power supplies currently available. The audio output is a 3.5mm stereo minijack; no audio signal is transferred through the USB connection.

Note: If you are wirelessly connecting a powered subwoofer to an AV receiver using the W3, then you will need one stereo minijack-to-RCA cable and one stereo RCA cable (both sold separately) to go along with the included minijack-to-RCA adapter. If you do not use the included minijack-to-RCA adapter, you can use two stereo minijack-to-RCA cables (sold separately).

Pairing: The Sender & Receiver in the W3 kit are linked together at the factory, so no pairing is necessary. If you have several W3 systems, multiple Receivers can be paired with each Sender, and vice versa, but each can only communicate with one of the other at a time. The W3 can transmit to up to 3 receivers (772W3R, sold separately) simultaneously.

Note: The newer chip-sets used in the W3 are not backwards compatible with the earlier Audioengine W1 or W2 wireless systems.

Proprietary Wireless Transmission: The W3 wireless kit transmits uncompressed PCM audio (15Hz-22KHz; +/- 1.5db) in the 2.4 GHz range (2.4-2.4835GHz) using a proprietary WiFi 802.11 protocol specifically designed for audio (up to 100'). The system avoids interference by constantly monitoring the entire 2.4 GHz spectrum and choosing the channel that can achieve the cleanest transmission. The system detects deteriorating conditions on the current channel and switches if needed in under 20 ms, without any interruption in the audio stream. The W3 also employs dynamic transmit power control, meaning it transmits with only as much power as required to maintain a clear audio connection. This makes W3 coexist better with other 2.4 GHz devices, including WLAN, Bluetooth, and other Audioengine wireless devices. The W3 incorporates a real-time streaming transmission technology designed specifically for music. It includes six quality protection innovations to achieve a robust wireless audio link.

  • Error-tolerant coding that incorporates forward error correction (FEC) coding. FEC ensures that lost bits can be completely reconstructed for common interferers and sources of bit errors. The coding is optimized for lossless performance against common and known interferers. FEC also enables error detection so the system knows when and where data is corrupted. It is analogous to techniques employed on Redbook CDs where the laser head incurs bit-errors as a result of imperfections in the pickup of data from the optical media.
  • For larger interferers, W3 employs sample interleaving and sample error concealment (SEC). This allows W3 to compensate gradually during periods of increasing signal degradation, thus minimizing audible discontinuities. When encountering interference bursts (up to 6ms in duration) SEC can recover every alternate sample, after which the hardware DSP performs linear interpolation to recover lost samples.
  • Packet error concealment (PEC) ensures there are no jump discontinuities in the audio stream during periods of severe interference, giving the system time to find a clean channel.
  • W3 employs intelligent, Dynamic Frequency Selection. The system avoids interference by constantly monitoring the entire 2.4 GHz spectrum, choosing the channel that can achieve the cleanest transmission. As conditions on a currently occupied channel deteriorate, the system detects this, and switches channels (in under 20 ms) without any interruption in the audio stream.
  • W3 employs dynamic transmit power control. This means that W3 is transmitting with only as much power as required to successfully maintain a clear audio connection. This makes W3 coexist better with other 2.4 GHz devices, including WLAN, BT, and other Audioengine wireless devices.
  • W3 combats RF fading, or multi-path-induced signal-strength fluctuations, by natively supporting antenna diversity. Support for dual antennas allows the system to "navigate" around zones of decreased signal strength by creating four possible antenna-to-antenna paths for the system to choose from on a continual basis. The end-result is an overall improvement in audio signal robustness due to an improved link margin.

Power Requirements: Power for the Sender & Receiver is provided from either a USB computer port, from the included AC power adapter, or from any other USB charger (such as an iPod charger). Another power source is the Audioengine 5+ powered speakers (sold separately), which are equipped with a USB power port on the rear panel.

Super simple bluetooth device.

Written By Anonymous, Charlottesville, VA on Wednesday, July 23, 2014
 
I purchased this unit for use with my DJ equipment. No more tripping over cables. After a quick look at the instructions, I was up and running in minutes. I did notice some infrequent audio drop outs. Moved the send and receive units a bit closer and problem solved.
Pros:
Ease of use and setup. Very compact.
Cons:
Occaisional audio drop out.

Couldn't be happier with this product! I was afraid there would be a lag when I hooked this system up to my Cambridge subwoofer, but it works flawlessly! No lag and it allows my subwoofer to be concealed and kept out of the way without having to run wires across the room. The setup was easy as well - literally plug it in to the wall, plug it in to the receiver and subwoofer, and it connects itself immediately. Virtually no setup.
Pros:
Easy setup, no lag, works flawlessly.

Worth Every Penny ... If You Can Establish A Clean Signal

Written By Flatpicnut, Morgantown, WV on Wednesday, October 09, 2013
Crutchfield Customer Review (What's this?)
 
After reading many reviews (on Crutchfield and elsewhere, which seem to universally average 4 out of 5 stars), I decided to give the W3 a try and purchased it "open box." My computer where the sender is located is approximately 35-40 feet from my stereo receiver, separated by a wall and a doorway. The W3 is mindlessly easy to set up. After establishing the connection with the W3 receiver without a problem, I flipped on Pandora on the computer. The sound was definitely redbook CD quality, so my first concern was allayed. However, my second concern - signal strength - was an issue right off the bat. Brief 1 sec. dropouts came at a rate of about 8-10 per minute. I had initially plugged the receiver unit into the "switched" outlet in the back of my AVR (located in a stereo cabinet). To get a better signal path with the sender, I was able to solve the problem by getting the W3 receiver out of the cabinet, dangling it from a couple of "cup hooks" that I put outside and in the back of the cabinet. I used a longer 3.5 mm to RCA patch cord to get the W3 receiver out of the stereo cabinet, and a USB extension cord so that I could get some distance between the W3 receiver and the power adapter. I moved it around until I found the best position (like fiddling with TV "rabbit ears"). I know it sounds like a hassle, but it has worked fine ever since. This gadget was worth the price and for me was a very cost effective alternative to the much more expensive Audioengine D2.
Pros:
Redbook CD Sound Quality Flexibility In Sending Any Audio From Computer To Stereo Reciever Cost (versus Audioengine D2)
Cons:
Signal Range/Strength

I returned it and up graded to a NAD DAC (#745DAC1). This product worked fine, but it did not expand the music as much as I expected. The NAD does what i wanted and it is only $50.00 more.
Pros:
easy set up
Cons:
does not expand the music enough

Audioengine W3 review

Written By Mike, Sturgeon Bay, WI on Sunday, February 03, 2013
Crutchfield Customer Review (What's this?)
 
The Audioengine W3 is an excellent product. I'm using it to sent audio from my laptop to my main audio system. This takes the place of an i-Pod with a dock. The W3 sounds better than the i-pod setup. It only seems to be limited by the source sound encoding in i-Tunes (lossless versus a lower sampling rate). There was a setting in my laptop that needed to be changed for proper operation and the Crutchfield tech helpline saved the day. Once the setting was changed I have not had an issue since. Use tech support if you experience a problem. I would recommend this unit to a frend.
Pros:
Works as advertised.
Cons:
None. It seems to be a great unit.

Audioengine W3

Written By Bob B, Brookline, Ma on Friday, December 07, 2012
Crutchfield Customer Review (What's this?)
 
I purchased Audio Engine speakers to be able to stream music from the cloud using my tablet. This poorly conceived, badly designed product completely made this totally cumbersome. I understood up front that I would have to plug the receiving unit into ac power. Because this adapter used a proprietary sending devine (rather than bluetooth or wi-fi) I would have had to plug the sending unit in as well. It was just not going to work. Unit was returned for a bluetooth receiver. Much simpler, and the difference in sound was minimal (if any).

Audioengine W3

Written By BillT, Chattanooga, TN on Monday, September 03, 2012
Crutchfield Customer Review (What's this?)
 
The Audioengine W3 system is a good little system for connecting your PC to a powered speaker system, and the speaker system must be powered as the signal is certainly not overpowering. I gave it 4 stars because it does as it advertises but falls somewhat short as it seems to be affected by objects in its way more than I would like meaning I had to put the speakers closer to the PC than I would like. And given the fact that it stops the sound from coming through the PC speakers (though I haven't worked with my PC settings yet to see if I can overcome this) it seems as if I just moved my speakers to a different part of the same room rather than to a different room altogether. But again, it is a good system and when you get the issues worked out it does produce a pretty good sound.
Pros:

Cons:

Audioengine W3. Wireless audio adapter kit.

Written By Michael, Daytona, FL on Monday, August 20, 2012
Crutchfield Customer Review (What's this?)
 
Although i am an Oxford graduate, I am also a technological ignoramus. IPods, Iphones, Blackberries, MP3s are utterly beyond my comprehension. I simply wanted a device that could transmit sound from my computer room to the living room. Had a chat with one of your agents (Rocky) about this. He finally decided that he had the ideal solution to my problem. His advice proved to be correct. It was exactly what I needed. Now I can listen to BBC radio, experiencing the same kind of sound clarity which I would were I living in London. If anything, the sound quality is superior to that of a live radio broadcast.
Pros:
Very easy to install. Even a dunderhead like me managed to do so without any hitch whatsoever. When you need to transfer the sound back to the PC speakers, you just extract the adapter from the front of the computer. It is that simple.
Cons:
Cannot think of any offhand.

Is there any audio delay with this system? I'm currently using a Dayton Wireless Subwoofer set to send a microphone signal to a speaker, but there's a very slight delay, which gets annoying with live audio. Thanks for your help! [ Peter Wood  Apr 14, 2014 ]

  • I was using this set up to send a signal from my AV amp to a Polk powered subwoofer. I stopped using it because of a slight audio delay. [ CHRIS   Apr 16, 2014 ]
  • Audioengine rates the W3 as having a <20ms latency, so technically yes there is a delay. However, 20ms is .02 seconds and only anyone with super human hearing would be able to detect that. I use the W3 to run my wireless sub and cannot detect any delay in relation to the rest of the signal. [ TODD   Apr 16, 2014 ]
