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.

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 specically 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 aect the audio.
The D2 Sender can simultaneously broadcast to (3) D2 Receiver units.
See the Pairing section for pairing additional receivers.

Pairing
• Only one channel plays through my D2.
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
conguration 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).
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.
