Crutchfield: Audioengine Desktop Audio Systems
Our take on the Audioengine D2 by Crutchfield's Dave Bar
Outstanding wireless sound from your computer
The Audioengine D2 makes it easy to enjoy music from your computer on your home audio system, in breathtaking detail.
If you store your music on a computer, the Audioengine D2 wireless DAC makes it easy to transmit audiophile-quality sound to your home audio system. No complicated networks, no fuss. The D2 creates its own powerful wireless network that runs independently from your home's Wi-Fi setup. The D2's transmitter accepts digital music from your PC via a USB cable or optical digital connection, then sends it wirelessly to the DAC/receiver where a sophisticated Burr-Brown processor transforms it into a high-quality analog audio signal for your stereo. This lets you bypass your computer's built-in sound card for a far more exciting listening experience. You'll enjoy sweet, nuanced sound previously obscured by the noisy environment inside your PC — delicate reverberations echoing in a concert hall, or the natural decay of an acoustic guitar chord. On good recordings, every instrument and vocal will stand out clearly and distinctly in its own separate space, allowing you to follow each one note-for-note.
Simple to set up. Easy to use.
The Audioengine D2 is ready to play in just moments. Simply plug the transmitter into a USB port or optical digital output on your MAC® or PC. Then connect the receiver/DAC to an audio input on your hi-fi system. Now hook up the included AC power adapters and you've finished all the wiring. All that's left is to turn on the power, press the Pair buttons, and you're ready to start enjoying fantastic-sounding music.
Versatile connections for your system
The Audioengine D2 offers three ways to incorporate it into your home audio system:
- Type B USB jack lets you feed one of the USB outputs of your computer into the D2's wireless transmitter, bypassing your computer's sound card for higher-quality sound with stored music files, online music services, and Internet radio stations. The D2's USB port can accept data rates up to 24-bit/96kHz, allowing you to transmit high-res music wirelessly.
- Optical digital input gives you an alternate connection for your PC, or any other PCM optical digital audio source. Send a high-quality wireless signal to your stereo system, and take advantage of the D2's high-performance DAC for better sound.
- Wireless USB-to-optical digital converter — If you already have a favorite DAC, the D2 can provide bit-perfect wireless USB-to-optical digital conversion, or serve as a wireless link between an optical digital audio source and a separate DAC with optical digital input.
A pair of high-quality gold-plated RCA outputs on the receiver/DAC lets you connect the D2 to your home audio system's amp, receiver, or a set of amplified speakers.
Very high quality audio over short ranges - works great over 50-75 feet; challenged over longer distances among different floors in my home.

Audioengine D2 Reviews
Average Customer Review(s):
Thanks for submitting your review
Overview: The Audioengine D2 Wireless Digital to Analog Converter (DAC) lets you wirelessly stream music from your computer (PC or Mac via USB) or another digital source (via optical digital, 2-channel PCM only) to your stereo system. The D2 uses the 2.4 GHz range, scanning the spectrum to select clear channels. If it detects deteriorating RF conditions, the system will select a cleaner channel, and move without any drop in audio. In this way the D2 can co-exist with other LAN devices.
Additional Receivers: Two additional receivers (772D2R, sold separately) can be added to the system (for a total of three) and paired with one transmitter simultaneously.
Simple Installation: The D2 system consists of a wireless transmitter and receiver. Simply plug the D2's transmitter into your computer's USB port and it becomes a sound card that transmits your computer's audio wirelessly to the D2's receiver, which connects to your home receiver via a stereo RCA or optical digital connection. The included transmitter and receiver are paired at the factory.
Audio Outputs: The D2 receiver has analog and digital audio outputs:
- Analog Output: stereo RCA outputs
- Digital Output: optical digital output (Toslink)
Note: If connecting to a television set's optical output, please make sure that you are able to select PCM as the default optical out audio format from your television's Audio menu. This DAC is not compatible with multi-channel audio signals and will not work with televisions that do not output PCM.
Power Supply: DC power supplies are included for both the transmitter and receiver. The transmitter can also be powered by a 5 volt USB port.

Why did you buy this?
I needed wireless streaming and this is the best there is for wireless. [ Leonard Jan 04, 2017 ]
Best specs for the price. [ Ramon Aug 10, 2016 ]
want to be able to stream high quality audio from my computer to audio system, plus Pandora [ Mark Jul 08, 2016 ]
I use the D2 to get digital HiRez audio from my bedroom iMac to my stereo system in the living room. Awesome. Very few dropouts. Good DAC too. [ HOYT Mar 26, 2016 ]
7 questions already asked
the D2 bypasses the sound card in the Mac, which a good thing as you get the much higher quality DAC in the D2 to process the sound. As such, you cannot use the volume on the Mac but must use the volume knob on the D2........however, if you are playing from something like itunes, which has a volume slider, you can control from there, but the volume knob on D2 is still the master. Hope this helps, and BTW, the D2 is awesome - great sound quality [ Mark Feb 08, 2017 ]
It can work with Sonos components that have an aux audio input. [ Paul Jan 01, 2016 ] Staff
1 answer Confused. If supported incoming sample rates on optical digital connection (from computer to D2 transmitter) are "up to 192kHz", but transmitter sends music over-the-air at only 24-bit/96kHz data rate, what use is the optical input to transmitter? Am I confused? Probably. So, how do I hook up to take advantage of 192kHz? (I can hear the difference on my system.) Thx [ HOYT Dec 14, 2015 ]
Yes, the wireless transmission is at 24/96 but an incoming signal with more information (optical 24/192) will still perform better than an incoming signal with less information (USB 24/96). The wireless convenience is definitely a trade-off but you will still benefit from the optical input and higher bitrate when available. Hope that helps! [ Ryan Dec 17, 2015 ] Staff
You can use any optical or RCA output on the amplifier. I would only use the headphone output as a last resort, but it will also work. [ Daniel Nov 19, 2015 ]
sorry, I have no experience with this. I use the transmitter to stream from my desktop mac office computer to my main system in the living room. The sound is great and it works flawlessly. [ MaryEllen Nov 17, 2015 ]
I forwarded your question to an Advisor and they responded with the following: The USB input on the Audioengine D2 is only compatible with a computer. It will work with both PC and MAC but you cannot connect an iPod or iPhone directly into it unfortunately. If you would like to discuss further you can contact an Advisor directly by phone (1-800-324-9695) or online chat. [ Krissy Jul 15, 2015 ] Staff
Sorry, I do not know the answer to this question. [ Eric Jul 01, 2015 ]
I didn't try from a different floor but I did try from different room; one in the front of the house and one in the back of the house with 2 walls in-between. I was using apple TV to accomplish the same thing prior to this purchase but apple TV limits the size of the file and it doesn't have a DAC. This had a DAC but also limited the size of the file so the sound quality was not any better. My goal was to improve sound not just move it wirelessly from my computer in my office to my stereo in the family room. I ended up returning this. I now use a mac mini at the source in my family room and have it connected directly to a DAC then into my home stereo system and the sound is incredible. It cost more but worth it in the long run. I can also control the music from my iPad. [ Rick Dec 20, 2014 ]
Yes. My computer is in one room with the Audioengine transmitter station hooked to it and the the receiver is in the living room about 100 feet away hooked into my stereo amplifier. I use it primarily to stream internet radio but also use it to play music from my iTunes library.Occasionally the transmission will turn off/on but I think it is related to the internet/radio transmission vs. the Audioengine, because I have never noticed it when playing iTunes . I am very happy with it's performance. [ Edward Dec 19, 2014 ]
