Welcome
Thank you for purchasing the Anedio D1 DAC!
Anedio is founded upon the principle that the enjoyment of highest-
quality music should be available for everyone not just for the
esoteric few. Our quest is to attain the most realistic and faithful
reproduction of music enabling the listener to experience its beauty
pathos joy and delight more fully. At the same time we strive to
make our products affordable by focusing on the essentials and
using the most cost-effective technologies. The result we believe is
a unique combination of sonic excellence and superb value.
At the center of the Anedio D1 is the ES9018 Sabre Reference 32-bit
DAC from ESS Technologies. Its oversampling modulator
optimized for accurate reproduction of music excels at maintaining
superb linearity at all levels tracking fast transients and resolving
lowermost signals. You will be able to hear minute details accurate
rendition of instrumental timbres and spacial cues from
reverberations.
The D1 DAC incorporates multi-stage jitter reduction circuits to
tame jitter as far as possible well below the threshold of audibility.
As the digital signal goes through each stage the jitter level is
progressively reduced until the critical final stage which is driven by
an ultra-low jitter oscillator with 0.5 ps rms jitter. Whether you
listen to music through USB or SPDIF the multi-stage jitter
reduction is highly effective delivering consistently natural
musical and relaxed sound.
The built-in volume control allows power amplifiers to be connected
directly to the D1 DAC eliminating the preamp in the signal path
when playing from a digital source. 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.
All the performance and quality are made available at an affordable
price by using highly-efficient manufacturing technologies and by
incorporating cost-reduction measures from the very beginning of
the design process.
We hope you will experience many years of joy and pleasure in
listening to music.

Placement of the D1 DAC
If you are using the D1 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 D1 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 D1 DAC accepts four digital inputs all of
which are galvanically isolated for excellent immunity to ground
loop noise.
Channel 1 — USB (16 bits 44.1K 48KHz)
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)
Line Output: Connect the left and right channels to a power
amplifier using a pair of RCA interconnects.

Extravagant interconnects with exotic materials are unnecessary.
Two characteristics however are important: (a) low shield (outer
conductor) resistance; (b) robust mechanical design for reliable
electrical contact. The shorter the cable the more transparent your
system will be.
Plug-and-Play SB Interface
The D1 DAC is a plug-and-play USB device. There is no need to
install a USB driver. Simply plug the USB input of the DAC into the
USB port of a computer and you can enjoy listening to music
immediately.
Connecting Power Cord
For the lowest ground noise and hum it is highly recommended that
the power cords of all components be connected to a single point —
usually a single surge protector with multiple outlets. This keeps all
components referenced to a single point as far as it is practically
possible thus minimizing the differences in ground potentials
among the components.
Never use a 3-prong-to-2-prong adapter to fix a ground loop
problem. This will disable the safety earth ground and may
cause electric shocks.
Isolating Cable TV Ground
If you have a cable TV connected to your audio system ensure that
the cable ground is galvanically isolated from the audio ground. The
cable TV ground tied to the earth outside your home is at a
significantly different potential and can cause audible hum if it is
not isolated properly. If you suspect this is the case insert a cable
TV ground isolator inside your home just before your cable set-top
box or TV RF input.
Surge Protectors
A surge protector is strongly recommended so that the components
are protected from large power lines spikes which can occur for
instance from lightning strikes.
Power Switch
The power switch is located in the back panel. Toggle the switch to

Anedio D1 DAC 7
the “1” position to turn power on. To turn power off toggle the
switch to the “0” position.
When turning on and off your music system with a power
amplifier the power amplifier should be the last component to
be turned on and the first component to be turned off. This
prevents power on/off transients from being transmitted to
loudspeakers.
Lock/ nlock Indicator LEDs
The green LED light just above the volume display indicates that
the DAC is properly locked to the incoming data. The red LED
indicates that the DAC is unlocked due to the absence of valid data.

Remote Control
The D1 DAC works with the Sony RM-EZ4 Universal Remote which
was chosen for its ergonomic design. Its large buttons easily visible
and intelligently placed make it particularly suitable for controlling
the volume level.
Only those remote keys described in the manual are functional.
For use with the D1 DAC select the “CBL/SAT” mode.
Channel Selection
The channel can be set either by pressing the channel button on the
front panel or by pressing the channel +/- button on the remote
control.
When selected the channel number is displayed momentarily (e.g.
“C2” for Channel 2).
Volume Control
The volume level can be set either by turning the volume knob or by
pressing the volume +/- button on the remote control.
Holding down the volume +/- button will continually increase or
decrease the volume level.

Anedio D1 DAC 9
The numeric keys on the remote control can also be used to set the
volume level. Simply key in the volume level followed by the “ENT”
key.
The volume level changes in steps of 0.5 dB. The maximum level 0
dB is displayed as “99”. For example “59” on the display means
that the volume level is -20 dB from the maximum.
Safe Volume Level
At power on the volume level is limited to a safe level (“81” on the
display) in order to prevent accidental damages to loudspeakers or
headphones.
To prevent entering high volume levels accidentally the level above
“81” cannot be entered directly from the numeric keys but only by
turning the volume knob or by pressing the volume + key.
As you change the volume from “81” to “82” you will hear a relay
click. The D1 DAC uses an optimal combination of 32-bit digital
attenuators and relay-controlled thin-film resistor dividers in order
to ensure highest signal-to-noise ratios at realistic listening levels
Mute (Remote Control Only)
The sound can be muted by pressing the “MUTING” button on the
remote control. Pressing the “MUTING” button again restores the
previous volume level.
sing Another niversal Remote Control
As with most people we do not like to pile up remote controls in our
living rooms. In case you want to use another universal remote to
control the D1 DAC we’ve made it easy to do so by using a common
IR protocol that is readily recognized by most universal remote
controls. Simply follow the learning instruction for the universal
remote of your choice and you will be ready to control the D1 DAC
within minutes.
