Cleaning
Your D2 components are not water-resistant, so it’s important that they
should be kept free of moisture. You should clean only with a dry cloth
or tissue and no liquid cleaners or solvents should be used.
Features
• Wireless bit-perfect 24/96 digital-to-analog converter
• USB-to-S/PDIF converter (wireless)
• Mac or PC plug-and-play, no drivers or network setup
• Precision re-clocking for low jitter
• USB and optical inputs
• Optical and RCA analog outputs
• Based on Burr-Brown PCM1792 DAC
Overview
The D2 24-bit Wireless DAC
is a simple yet powerful
wireless digital-to-analog
converter with performance
and features generally found
only in much more expensive
DACs. It can accept USB or
PCM-stream optical inputs, and will automatically congure to match
the inputs you deliver, with the optical input being dominant. The
wireless operation is totally transparent, requiring no special network
setup or drivers.
The D2 can process digital audio at any bit depth up to 24 bits, and
any sample rate up to 192KHz. The D2 USB input can accept a USB
audio stream from your computer or other USB source device. The D2
optical input can accept optical (PCM stereo) streams from any optical
(TOSLINK) source, such as computers, TVs, Apple TV, DVD/BluRay
players, CD players, etc.
Note: Optical sources must be set to PCM Stereo.
The D2 Receiver output can be connected to any gear with an analog
(RCA or minijack) audio input, such as powered speakers, stereo
system, etc.
The D2 Receiver also includes an optical output, which can be used to
connect your own DAC or stereo receiver. Thus the D2 system can act
as a wireless USB to S/PDIF converter, as well as a wireless optical link!
Power for the D2 Sender can be provided via USB or the included
power adapter.
Note: Use only the provided Audioengine power adapter. The
Audioengine adapter is specically designed for maximum audio
performance, and the use of other adapters may damage your D2.
Note: When using the D2 with the optical output of your computer,
the USB port on the computer can provide power. The D2 will sense
that an optical input is present and give that input priority.
Internally, USB power is “double regulated” to ensure that no USB bus
power variations aect the audio.
The D2 Sender can simultaneously broadcast to (3) D2 Receiver units.
See the Pairing section for pairing additional receivers.

input of your active speakers, stereo, etc.
Step 3 -- Connect the D2 power adapter to the D2 Receiver, and to an
AC power source.
Optical Source
Step 1 -- Connect an optical output of your computer, TV, Blu-Ray, DVD,
etc. to the optical input of the D2 Sender.
Step 2 -- Connect the D2 power adapter to the D2 Sender, and to an AC
power source.
Note: Verify that your source is set to PCM Stereo.
Step 3 –- Connect the analog output of your D2 Receiver to any audio
input of your active speakers, stereo, etc.
Step 4 -- Connect the D2 power adapter to the D2 Receiver, and to an
AC power source.

Pairing
Pairing is the function by which two devices become acquainted. Once
a Sender and Receiver(s) are paired, they will remember one another.
Note: D2 Senders and Receivers packaged together are paired out
of the box, so if you’re only using one Sender/Receiver set, no further
conguration is needed.
To pair an additional Receiver or to re-pair a Sender/Receiver set, press
the Pair button on the Receiver (the Pair LED will blink), then press the
Pair button on the Sender. Both Sender and Receiver pair lights should
now be solid, indicating that they are paired.
Troubleshooting
• I have connected my D2 Sender and Receiver as shown, but there is
no music output.
1. Check to see that the Power and Pair lights are lit and solid. If
not, try another USB port on your computer.
2. If the Pair light is blinking re-pair the Sender and Receiver as
discussed in the Pairing section.
3. Verify that “Audioengine D2” is selected as your output device
under Control Panel (PC) or System Preferences/Audio (Mac).
4. Try another USB cable.
5. Verify that the proper input source is selected on your audio
system.
• I have connected my D2 to my TV/DVD/BluRay, but there is no sound
output.
1. Verify that the D2 Sender and Receiver are both connected to a
power adapter and that the power lights are lit.
2. Be sure that your source digital audio is set to “PCM Stereo”.
• Only one channel plays through my D2.
1. Check the RCA cables between your D2 and your sound system.
2. Check your audio player to ensure that the balance is centered.
Break-In Period
Your DAC will sound great out of the box and will get better over time.
However, give it 40 to 50 hours break-in time before doing any critical
listening.
