Our take on the Audioengine D2

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.

Easy set up. No long cables connected to my amp. Sounds great.

Pros: Light. Compact. Easy set up and use. Great sound.

Cons: None

Would not recommend.

Lance from Richmond, VA on 2/5/2018

Crutchfield Customer Review (What's this?)

Started off working flawlessly. After about 4 months of use, it started randomly cutting in and out for no reason. I moved the unit within 4 feet just to make sure it wasn't a distance issue (originally had it about 25 feet) but it made no difference. Also, I have to occasionally unplug the USB from my computer to reboot the base unit to get it to work. I thought this might have ben a computer issue but I've used it on 2 different computers including a 2017 iMac - same issue. I like the size ands simplicity of the D2 but nothing ruins the music listening experience more that having a song randomly cut in and out.

Pros: Size, Simplicity.

Cons: Not reliable.

Not worth the money

Crutchfield customer from Baton Rouge, LA on 1/26/2018

Crutchfield Customer Review (What's this?)

When it works, the sound quality is great. I've had intermittent problems with the setup. I optimized my PC to ensure enough resources were available for audio processing. However, occasionally the audio would "fade" in and out, as if it was losing the wireless signal. I tried everything suggested on the troubleshooting webpage from the manufacturer, but no luck. I am convinced it is a wireless issue, and I will be trying a hardwired alternative. I am disappointed that a wireless product is not robust enough for daily use, even though my receiver is less than 6 ft. from the transmitter in this setup. Definitely not worth the money spent for this product.

Pros: Great sound Easy install

Cons: Inconsistent quality Poor wireless connectivity Not worth the price

A bridge between audio worlds

Rob from Fort Collins, CO on 5/8/2017

Crutchfield Customer Review (What's this?)

The Audioengine D2 extends a digital audio stream from a Mac laptop to our stereo system flawlessly. The sound quality seems to be limited only by the streaming source. The product is very simple to set up. It's range is less than quoted, at best 40 feet when traveling through a cabinet and past a heating duct, but it is adequate for our purposes.

Pros: excellent quality sound much more convenient than a wired connection

Cons: range may be limiting

Great sound - fills a need

Joe from Annapolis, MD on 1/22/2017

Crutchfield Customer Review (What's this?)

Very high quality audio over short ranges - works great over 50-75 feet; challenged over longer distances among different floors in my home.

Pros: very high quality

Cons: difficulty connecting at longer ranges

Solves 3 issues at once, and sounds great too!

Arthur Ball from Blacksburg, VA on 12/4/2016

We love this unit. Our computer if far from our stereo, and this solution is pretty much the only game in town for an interference-free long-distance wireless transmission in a compact package. We've been using it daily for over 3 years and have had zero issues. Despite the fact it seems cheap in my $60,000 hi-fi stereo system, it makes us happy every day. In absolute terms, the sound is a tad soft, dynamics aren't incredible, and it is a bit low on gain, but none of that bothers me when I'm listening, and its comfortable style actually suits compressed music perfectly. I'm satisfied with the D2, and that's saying a lot!

Pros: Excellent, enjoyable sound So practical and convenient Killer price Perfect reliability

Cons: People underestimate it due to its low price

Ed S from chandler, AZ on 2/3/2016

Crutchfield Customer Review (What's this?)

The sound quality is excellent, however, the unit clicks on and off on a regular basis. I even moved them closer together with no success. Audioengine was kind enough to sent me a replacement after the warranty period, but the new units did the same thing. I'm going to try a different plug and play wireless DAC before I look for an alternative.

Pros: Quality sound when it performs.

Cons: Constant signal pausing.


HVTR from SARASOTA on 5/17/2015

Crutchfield Customer Review (What's this?)

Bought this set about a month ago. Arrived promptly, packed in two separate boxes, one for the transmitter, one for the receiver. Connected the transmitter to an USB port on my PC and the receiver via the supplied RCA cable to my music system, powered up and within a few seconds the two lights at the transmitter and at the receiver were stable and communication was established. Just adjusted the volume at the transmitter to balance the sound level to the CD and phono inputs of my music system. No hassle, no issue from the unit Caution: Nothing to do with the unit and maybe specific to my soundcard. When you plug in and go to the playback devices settings, you will see your PC automatically recognized the audioengine but no sound its being output. This is a soundcard issue, not an Audioengine issue. And this because the soundcard on my PC cannot handle two outputs simultaneously. To solve, under the properties tab disable the speaker of the PC and enable the Audioengine instead. You will have to switch back if you want to listen through your headphones/speakers on the PC. Other PC's might not have this issue. Am using it to operate my iTunes over the whole house. -Download the Apple remote app to your Iphone or iPad -launch Itunes on your PC and activate home sharing. -When you launch the Apple remote app, the system will search for a library and you now can control your music from any place in the house where your music system has speakers.

Pros: Works as advertised, no issues

Cons: Beware of the distance between transmitter and receiver with obstacles in between. In my house the signal has to travel through 3 brick walls over a distance of 36 feet and this is at the limit. If you stand in the signal path close to the receiver the signal drops out

Performs Flawlessly

djf from Maryland on 1/21/2015

Crutchfield Customer Review (What's this?)

I originally order the NAD DAC2 from Crutchfield for my iMac based system. Unfortunately the NAD's wireless signal was too weak to work in my environment. So I returned the NAD for the AudioEngine D2. Installation took less than 5 minutes and has worked perfectly with zero dropouts. The AudioEngine D2 provides a neutral analog output which works well with my Thiel speakers. (Though I found the NAD a bit warmer...when it worked!) All in all, I recommend the AudioEngine D2 for any systems where line of sight wireless is not possible. Finally, kudos to my Crutchfield advisor for his recommendations and for a smooth return/reorder process.

Pros: Strong wireless signal; simple installation; good digital to audio conversion; flawless operation.

Cons: DAC could output a bit warmer sound.

Crutchfield Customer Review (What's this?)

When I order this product, a technician called me. He suggested that JRiver was the software to use with this product. JRiver has too many adds. I got the product to work with fubar2000. It took me about 8 hours doing google searches to get the product to work. Cambridge audio provides drivers for their DACs, but the company that made the DAC I purchased does not. Eventually I found a work-around by chance.

Pros: Works great once you have the correct driver for your operating system.

Cons: No driver or directions provided with the product.

GOS from Morris Plains NJ on 3/30/2013

Crutchfield Customer Review (What's this?)

Looking for a DAC that that would allow me to stream any music files and/or formats from my laptop to a high end system. This unit works as advertised. Easy set up and strong signal strength. With the added convenience of wireless and not having laptop tethered to computer

Pros: Reasonable price, easy set up, strong signal from various positions in house, allows USB or wall wart for power, allows user to stream any music files to a high end system

Cons: Power switch, volume control and all inputs are all grouped together on rear panel. Would prefer power switch and volume control to been on front, inputs on back.

Absolute Winner

ecericson007 from Denver, Co on 1/13/2013

Crutchfield Customer Review (What's this?)

Running it through Conrad Johnson amp/pre-amp and Concert Grand speakers, and the D2 matches a quite expensive CD player. Although I needed to reload my CD collection as WAV, It has been well worth the time. The installation was a no brainer, and I plan to add a D2R for my secondary system. Of course, I need some 24 bit source to really get the most out of the system.

Pros: No brainer install and excellent quality.

Cons: Now I need to update my source to get the most out of D2.

Abraham R. from Albion, NY on 12/16/2012

Crutchfield Customer Review (What's this?)

This is a phenomenal piece of equipment. It does what most other components in this niche cannot do and is very easy to set up. The sound quality is impressive. I have it hooked directly to my amplifier while my preamp is being serviced and I am extremely pleased with the outcome. The only downside is that it won't do 24bit/192khz FLAC music files. The only thing out there that will do that is the Apple TV but, that is going to be pricier ( requires the purchase of a separate digital DAC and in my case, the purchase of a new TV) and also requires a move complex configuration and I am not sure how that will work with my equipment. At this point, I am not sure if I will keep it or go the route of the Apple TV.

Pros: Easy to set up. Excellent sound quality.

Cons: It won't play 24bit/192khz music files.

A winner!

Jeff E from Chapel Hill, NC on 4/19/2012

Crutchfield Customer Review (What's this?)

Easy to use. Great sound with the RCA outputs into the preamp. Spectacular sound with the optical output (optical cable not included) into my upsampling DAC. Internet radio now a wonderful option (sound far better than HD into the same amp and speakers). Highly recommended. Also recommended is AudioEngine's customer service. Extremely friendly and helpful.

Pros: Portable. Easy to set up. Versatile. Great sound.

Cons: None.

Pros: It's all good

Cons: Can't find anything to date


Hands-on research

Product Research


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.


  • Input Signal:
    • USB: 96 kHz/24 bit
    • Optical: 192 kHz/24 bit (if an optical signal is present, it takes priority over the USB signal)
  • THD+N: <0.0015% (1 kHz/96 kHz)
  • Signal-to-Noise Ratio: >115 dB
  • Analog Output: 2 volts RMS/100Ω
  • Frequency Response: 10 Hz to 30 kHz (+/- 0.5dB)
  • Crosstalk: <-85 dB
  • RF Band: 2.4 GHz (2.405 GHz to 2.477 GHz)
  • Transmission Range: >100'
  • Power Requirement:
    • Transmitter: 270 mA/6V
    • Receiver: 300 mA/6V

Dimensions: Receiver and transmitter are the same size:

  • Width: 4.766"
  • Height: 1.066" (3.767" including antenna)
  • Depth: 5.515" (7.355" including power plug and antenna)

Why did you buy this?

After looking at many reviews this product seems to fit my requirements for wireless streaming of quality audio at an affordable price with great reviews [ LINDSEY CLYDE  Sep 12, 2017 ]
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 ]
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
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 ]
