High-res audio

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.

Product 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

Turn 1s and 0s into sweet sounding music

Why buy a separate DAC? These devices are all about getting true high-fidelity sound from digital sources like computers, streaming music players, smartphones, and more. While these kinds of sources usually have their own digital-to-analog converters built in, you can expect a separate DAC to give you much better accuracy and finer detail.

Crutchfield Customer Review (What's this?)

I got the the wireless DAC to hook my Mac computer to my stereo witch is on the opposite side of the room. It works very well, the digital to analog converter does give higher quality sound than a direct connection to the Mac. The instructions should have but did not tell you to go to sound preferences and change it to external to make it work. Otherwise Avery good Product.

Pros: Easy to install, good performance for price.

Cons: None

Best kept secret, plays any sound App on PC

Written By Ron, Trinity Fl on Friday, June 05, 2015

Started building new wired stereo with DAC 1. Since then have searched exhaustively for a better solution. This is the easiest and most flexible. Just plug into USB port and play hi quality sound through my 3 Russound amps in a closet. I play from my patio or piano room, no problem. The center of my house is open so not a lot of partitions to block signal. My CD collection is on a NAS USB drive so I don't need a laptop with a lot of memory.

Pros: Easy setup, flexible, quality sound, full control of apps; volume, skip, change station, now playing, etc.

Cons: Need laptop with USB port.

Flat, Even, Wireless, Delivery!

This thing is cool! If you have a killer sound system, it is like having the entire CD store at your finger tips. I personally prefer vinyl but records are not cheap anymore and digital is catching up ("trust me, it is not there yet."). So why not test out what you like before you buy.

Great Sound -- Limited WiFi Range

Crutchfield Customer Review (What's this?)

I loved the rich and nuanced sound of high res music through the DAC 2 when connected to my MacBook. But I wanted to use it primarily with my iMac which was not within line of sight (though less than 50' away). The wireless connection was weak on all 3 channels with multiple drop-outs. So unfortunately I returned it for the Audioengine D2 which has solid wireless connectivity and fine sound.

Pros: Audio quality and easy installation.

Cons: Weak wireless range.

Easy to set up and works well

Works as advertised

Pros: Easy to set up and use

Cons: Have not found any yet

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.

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.
