High-res music with wireless convenience

Liberate the music trapped in your computer with NAD's DAC 2. This USB digital-to-analog converter gives you an easy way to send music wirelessly from your computer to your existing home theater or stereo, while providing clear, detailed sound. Anything that you can listen to on your PC or Mac®  you can now enjoy on your best speakers. The DAC 2's two-piece design features point-to-point wireless technology that delivers uncompressed, full-bandwidth audio — including high-resolution music files up to 24-bit/96kHz. And because it's a closed wireless system, you don't even need a Wi-Fi® network to use it. 

Simple to set up. Easy to use.

Right from the box, the DAC 2 is ready to play in just moments. Simply plug the included transmitter module into a USB port on your computer, and the DAC 2 becomes your PC's sound card. The transmitter bypasses all of the analog circuitry in your PC and transmits a digital signal directly to the receiver module that's connected to your hi-fi system. The digital signal then gets converted and sent as an analog signal to your stereo amplifier. The DAC 2 uses premium components in a proprietary circuit for accurate, musical sound. It also sports a coaxial digital output that allows downstream digital processing by a different DAC or a home theater receiver.

Highlights:

  • high-quality Burr-Brown op amps and digital-to-analog converter for detailed sound
  • supports audio sample rates up to 96kHz/24-bit for streaming high-res music files
  • wireless USB transmitter plugs into your computer
  • Wi-Fi network not required — uses point-to-point 2.4GHz wireless technology for uncompressed, full-audio-bandwidth transmission
  • built-in driver for USB connection
  • stereo RCA and coaxial digital outputs for connection to a stereo or home theater system
  • transmission range: up to 131 feet
  • frequency response: 20Hz to 48kHz (± 0.5 dB)
  • THD + Noise: 0.05%
  • signal-to-noise ratio: greater than 80 dB
  • external power supply with 58" cord included for DAC receiver
  • 7" mini-USB (type-B) to USB (type-A) adapter cable for USB transmitter included
  • 50" stereo audio RCA cable included

Overview: The NAD DAC 2 Wireless USB Digital-to-Analog Converter lets you wirelessly stream your high-resolution music from your computer (PC/Mac) to your Hi-Fi stereo system with high performance sound. The NAD DAC 2 uses point-to-point 2.4GHz wireless technology which means you can just plug in the two-piece DAC 2 and start enjoying computer audio from your home entertainment system in minutes.

2.4GHz Wireless Connection: You don't need a Wi-Fi network to connect the NAD DAC 2 to your computer and home audio system. The NAD DAC 2 Wireless USB Digital-to-Analog Converter uses point-to-point 2.4GHz wireless technology which features the full audio bandwidth (20-20kHz) and remains uncompressed to maintain HD sound quality.

Simple Installation: The NAD DAC 2 Wireless USB Digital-to-Analog Converter consists of a wireless Receiver and Transmitter. Simply plug the DAC 2's Transmitter into your computer's USB port and it becomes a sound card that transmits your computer's high-resolution audio wirelessly to the DAC 2's Receiver, which connects to your home receiver via a stereo analog or coaxial digital connection.

Note: There are Channel switches (1-3) on the Receiver and Transmitter. Make sure these switches are set to the same number.

Wireless USB DAC Transmitter: The DAC 2's Transmitter consists of a mini-USB (type-B) connector with a mini-USB (type-B) to USB (type-A) adapter cable. Using the included USB cable, the DAC 2's Transmitter plugs into your computer's USB (type-A) port and bypasses all the analog circuitry in your PC and then wirelessly transmits high-resolution audio directly to the DAC 2's Receiver, which is connected to your hi-fi system, using the native digital format for the best possible sound.

Wireless USB DAC Receiver: The DAC 2's Receiver consists of a integrated Digital-to-Analog Converter with analog & digital audio outputs. Once the wireless HD audio is received at the DAC 2's Receiver from the DAC 2's Transmitter, the digital signal is converted and sent as an analog signal to your home receiver through stereo analog audio outputs. There is also a coax digital output that allows downstream digital processing.

24-Bit/192kHz DAC: To achieve the best possible sound, the DAC 2's Transmitter digitally transmits the HD audio from your Mac or PC to the DAC 2's Receiver, which then converts the digital signal to analog using premium Burr-Brown OPAmps (TI PCM1781) and 24-bit/192kHz Delta-Signma DACs with selected passive components in a proprietary NAD circuit.

Compatible Sampling Rates: The NAD DAC 2 Wireless USB Digital-to-Analog Converter supports high-resolution audio sampling rates up to 24-bit/96kHz.

Audio Outputs: The NAD DAC 2 Wireless USB Digital-to-Analog Converter is fitted with both analog & digital audio outputs

  • Analog Output: The NAD DAC 2 features one stereo audio RCA output to connect to your home stereo receiver.
  • Digital Output: The NAD DAC 2 features one coaxial digital output to connect to your home theater receiver.

AC Power Supply: The NAD DAC 2 Wireless USB Digital-to-Analog Converter includes an external AC power adapter.

NAD DAC 2

Written By Jack G., Clearwater, FL on Sunday, January 19, 2014
Crutchfield Customer Review (What's this?)
 
Signal faded and sometimes was distorted. Transmitter and receiver were only one room apart. Also,,I noticed no noticeable sound quality improvement versus playing straight digital MP3 format. I returned it without any issues--just as you would expect from Crutchfield.
Pros:
Easy to hook up.
Cons:
See review. Could use a bit longer USB cable so unit could be placed without almost dangling from my PC.

Hi guys, I'm curious if this unit can be use to 230v 50hz country. Autovolt unit? I'm very interested getting this but it's not available in my country right now. [ Jjacob  Sep 25, 2014 ]

  • This unit includes AC plug adapters for US, AU, EU, and UK. [ Jeff Staff  Sep 26, 2014 ]
Similar question to Alex G. - does this truly have to be line of sight to work? My laptop is on 3rd floor and home stereo is on first floor. Also, what is the interface like to control iTunes since that is what I will mostly be streaming that from laptop to stereo? [ Fred C.  Feb 26, 2014 ]

  • Mark, great answer and thanks. I have a NAD CD changer and agree on the quality but this may just be a limitation of the DAC using its own dedicated system. Either I will try this product or come up with another solution for streaming my digitized library. [ Fred C.   Feb 27, 2014 ]
  • NAD makes really good stuff so I was a little disappointed when I tried the DAC-2. It worked ok line of sight for about 20'. Unfortunately I had no luck using it with a wall between the units. WiFi works just fine in the same area from a WAP that is further away. Probably worth a try though. These things seem to depend on your particular situation. As far as interfaces go it's really simple. It's just a USB audio device. No setup in my case. The PC just found the new audio device and started using it. I have several wired DACs and similar for those. [ MARK   Feb 27, 2014 ]
  • I do not recommend it. I couldn't get it to work well in the next room (same level). I returned it to Crutchfield. It should perform much better especially for its price. [ JACK   Feb 27, 2014 ]
  • No, it will not work floor to floor, or room to room even without a direct sight line. I absolutely love this product, of course I wish it had more range too, but you can't have everything. I use it on iTunes as well and it works flawlessly. You just have to change your output from the headphone jack to the USB port [ Michael   Feb 27, 2014 ]
  • I had mine set up pretty much in line from computer to amp. It worked great, and the lack of wires. There is really no interface to speak of. The NAD DAC2 takes control of your sound card, and becomes another audio out channel. How that interfaces with iTunes is unknown to me as I do not use it. In the players I do use, it is simply a matter of selecting the NAD Audio Driver as the output and off you go. [ RICHARD   Feb 26, 2014 ]
  • Hi Fred,My set up was only 25 ft away and in another room. It worked ok, but if someone walked in front on reliever, the signal was lost. Sound was great when it worked, but when I had people over, signal kept dropping when someone walked in front of receiver. Maybe if you put it up high it would work better. I bought an inexpensive DAC online and hooked it up to my Apple TV optical out and that worked fantastic. Not just my computer streams to it, but also iPhone and iPad. And the sound is really good. Plus the DAC 2 has to be set as sound output on computer. If you want to listen just to computer speakers , you have to open prefences and change sound output. Hope this helps. BTW, I've been a recording engineer for over 30 years, so audio is my life.Bobby [ ROBERT   Feb 26, 2014 ]
So, seeing as my home office with computer is downstairs and my stereo system is downstairs, how would I pick and choose music to listen to from downstairs? I currently am using an iMac with iTunes. [ Alex G.  Dec 21, 2013 ]

  • I purchased the NAD DAC 2 in order to address, what seems to me, a similar situation as yours. Our home computer is on our second floor with the main stereo system on our first floor. I, too, wanted to be able to stream music from the itunes library on the computer upstairs to the hifi system on the first floor. The NAD DAC 2 works splendidly!! I first had trouble with a great deal of interference and thought I may have to return the product. The receiving unit was initially placed inside a cabinet, in close proximity to our staircase, containing a blu-ray player, integrated amp and an aging NAD CD player. With this configuration, any time someone ascended or descended the stairs, the music would cut off, hesitate, or garble. I then repositioned the receiving unit out the BACK of the cabinet (still using very short (~18 in.) RCA cables) with a now relatively clear "path" to the transmitter unit atop the stairs, with nearly perfect results (there is now, only VERY rarely an occasional "hiccup" when initiating a listening session from itunes via apple remote (there are no issues DURING listening or switching tracks etc. even with 4 active kids supplying potential "interference" problems)! I would not hesitate to recommend this product with the proviso that there may be some optimization of signal path required for it to work properly. Great sound! Fantastic convenience! Hopefully this helps you with you query :) [ NATHAN   Dec 21, 2013 ]
  • Hi I have been using this DAC for the past few months and have fnd it to be excellent for thr price paid However if the dac reciever and the tranmitter are not in line of sight, it will not work properly. They have to be truely on line of sight. If you move even to the next room, it will not work properly and the songs will skip Trust that helps. [ SOMVEER   Dec 21, 2013 ]
  • From your computer. [ RICHARD   Dec 21, 2013 ]
