Anedio D2 DAC

USB Driver Installation (Windows Only)
Before connecting the D2 to your computer, please install
the Windows driver first.
On Mac OS X, there is no need for driver installation since the
USB 2.0 audio is supported natively.
(1) Insert the Anedio USB Driver CD into your PC.
If the installer does not launch automatically, then click
ausbaudio_v1.22.0.exe in the CD directory.
Some USB devices might interfere with the installation of the D2,
and it is better to disconnect all other USB devices attached to
your computer.
(2) Follow the onscreen directions. Please allow 1 – 2 minutes for
the installer to complete. On older computers, it may take
longer.
(3) When instructed to plug in the device, simply connect the D2 to
the PC using a USB cable.
When plugging the USB cable into the USB input, be sure
to apply sufficient force so that the plug is inserted
promptly without hesitation.
Setting up Media Players for Bit-transparent Playback
The D2’s USB interface is bit-transparent, passing on the audio data
without any alteration. However, to ensure bit transparency all the
way from music files to the DAC, you still need to set up the media
player software properly.
Please see our website (under “Technology”) for detailed
examples on how to setup media players for your operating
system (Windows 7/Vista, XP, or Mac OS X).

Anedio D2 DAC
Placement of the D2 DAC
If you are using the D2 DAC primarily to listen to music through
loudspeakers (instead of headphones), place the DAC and the
amplifier
between the two loudspeakers
, instead of setting it off to
one side. This keeps the lengths of interconnects and speaker
cables short for optimal sonic performance.
Remember that the ideal cable is no cable.
The signal can never
be improved by going through a longer cable
. As you shorten the
cable length, the signal fidelity approaches that of the ideal cable.
The best practice, therefore, is to keep the cables as short as
possible by placing the DAC and the amplifier between the
loudspeakers.
Bypassing the Preamp
If all your music sources are digital, you do not need a preamp. The
built-in volume control allows power amplifiers to be connected
directly to the D2 DAC.
Bypassing the preamp is one of the most
significant steps toward a higher level of transparency
. To ensure
highest signal-to-noise ratios at realistic listening levels, our design
uses an optimal combination of 32-bit digital attenuators and thin-
film resistor dividers.
Connecting Interconnects and Cables
Before connecting, turn off the power to all the components
in your system.
Digital Inputs
: The D2 DAC accepts four digital inputs, all of which
are galvanically isolated for excellent immunity to ground loop noise.
Channel 1 — USB
(24 bits, 44.1K, 48K, 88.2K, 96K, 176.4K, 192KHz)
Channel 2 — SPDIF, 75-ohm BNC
(24 bits, 44.1K, 48K, 88.2K, 96K, 176.4K, 192KHz)
Channel 3 — SPDIF, 75-ohm RCA
(24 bits, 44.1K, 48K, 88.2K, 96K, 176.4K, 192KHz)
Channel 4 — Toslink, Optical
(24 bits, 44.1K, 48K, 88.2K, 96KHz)
