Installation & Placement
The Nēo 280D requires only minimal ventilation to
maintain an optimum and consistent operating
temperature. However, you should avoid placing it near
a heat source as this could compromise the Digital-toAnalog Converter’s performance and reliability. As well,
it should be placed on a solid level surface. The 280D
uses toroidal transformers; even though they are well
shielded, you should not place the Digital-to-Analog
Converter too close to source components sensitive to
EMI, such as a turntables.
In the event that your Nēo 280D is equipped with the
“MiND” Music Streamer option and you intend to use its
wireless streaming feature (between your wireless
router and your 280D), you must install the included
Wi-Fi antenna on the back panel by screwing it into the
socket labelled “WIFI ANT”.
For Nēo 280D’s equipped with the optional
“MiND” Music Streamer, please visit our
website to download PDF versions of both the
“MiND Setup Guide” and “MiND App User
Guide”.
If you intend to use the Nēo 280D’s USB input
connection (PCM or DSD) with a Windowsbased computer, you will need to install our
USB HD DSD driver, which can be downloaded
from the support section of our website.
Note: Apple-based computers don’t require this
driver.

280D Nēo Series
Front Panel Controls
Figure 1: Nēo 280D Front panel
The front panel will look similar to Figure 1 (above). The “Standby” button disengages all internal circuitry from the
power supply. When switching back from “Standby” to the “on” mode, the selected ‘input’ will be memorized from
the previous listening session. The blue indicator LED turns off when the 280D is in “Standby” mode.
The button labeled “BT” activates and deactivates
the Bluetooth discovery mode. When the Nēo
280D is in discovery mode, you can pair a smart
device (iPhone, iPad, Android, etc.) to the 280D. To
begin, press the “BT” button and the corresponding
“BT” LED will begin to blink continuously until
pairing between your smart device and the 280D is
successful or the 30 second time limit has been
exceeded. When “MOON 280D…” appears in the
Bluetooth device list of your smart device, simply
select it; the “BT” LED will stop blinking to confirm
that pairing is successful. This procedure only needs
to be performed once for each smart device.
The two (2) buttons labeled “ Input ” allow you to
sequentially scroll, either forward “” or backward “”
through all of the digital inputs. These inputs are
ordered as follows going forward (): “OPT1”, “OPT2”,
“SPDIF1” , “SPDIF2” , “BT” (Bluetooth) , “NET” (optional
MiND network player), “USB” and “AES-EBU”. There are
eight (8) corresponding red LED’s to the right of these
input buttons, indicating the currently selected input.
The Nēo 280D is capable of processing a PCM digital
signal at one of the following eight (8) different
sampling rates: “44.1”, “48.0”, “88.2”, “96.0” , “176.4” ,
“192.0” , “352.8” and “384.0” (all in kHz) or a DSD digital
signal at one of the following three (3) data rates DSD64
(2.82MHz), DSD128 (5.64MHz) and DSD256 (11.28MHz);
There are eleven (11) LED’s on the right side of the
faceplate that indicate the PCM sampling rate or DSD
data rate of the source material currently being played.
8
The Nēo 280D is Energy Using Product (EuP) compatible.
This is a European standard that effectively limits the off
and standby power consumption to no more than 0.5W.
When the EuP function is active, the unit will
automatically turn off after 20 minutes of inactivity. The
“BT” button allows you to activate and de-activate the
EuP function as follows; press and hold the “BT” button
for approximately 3 seconds to toggle EuP on (default
setting) or off. The blue “Standby” LED will blink twice
when the EuP mode has been turned off and will blink
four times when the EuP mode has been turned on. The
EuP setting is maintained when the 280D is both
powered down and placed into “Standby” mode. Finally,
if you have the MiND option installed in your Nēo 280D,
the EuP mode will be permanently disabled.
Notes: (i) DSD format signals can ONLY be played
through the USB input. (ii) PCM format signals
with sample-rates of 352.8kHz and 384kHz can
ONLY be played through the USB input. (iii) you
cannot connect a USB flash drive or external hard
drive to the “USB” input.
If your Nēo 280D is equipped with the optional “MiND”
network streaming module, the assigned input is “NET”,
and the corresponding sampling rate LED will
illuminate, as it does for all other inputs.

Owner’s Manual
Rear Panel Connections
Figure 2: Nēo 280D Rear panel
The rear panel will look similar to Figure 2 (above). On the left side are two pairs of analog outputs; Labeled “Right”
and “Left”, each with a single-ended RCA and balanced XLR connector. These are “Fixed Level” outputs, intended to
be connected to a line-level input on either your preamplifier or integrated amplifier. We strongly recommend that
you use the balanced XLR connectors to maximize performance. Don’t hesitate to use high quality interconnect
cables*. Poor quality interconnect cables can degrade the overall sonic performance of your system.
There are six (6) “Digital Inputs” as follows: “USB” using a
type-B USB connector; two (2) optical inputs using
Toslink connectors labelled “OPT1” and “OPT2”; two (2)
S/PDIF inputs on RCA connectors which will benefit
most from cables with an impedance of 75Ω; and finally
a 3-pin XLR connector for an AES/EBU input which will
benefit most from a cable with an impedance of 110Ω.
All of these inputs correspond to the front panel LED
input indicators. Don’t hesitate to use high quality
digital interconnect cables*.
The space above and to the right of the row of digital
inputs is reserved for the optional “ MiND” Music
Streamer. If your Nēo 280D is equipped with the
“MiND” option, you will see a socket for a WiFi antenna
and a RJ45 ethernet connector socket. Please consult
the “MiND Setup Guide” and “MiND User Guide” for
further details.
The right side of the rear panel has various connectors
for external communications. The Nēo 280D is
equipped with full-function bi-directional RS-232 port
control and status for custom integration or
automation, as well as future software updates. Next to
the RS-232 port are two (2) “SimLink™” connectors
labeled “in” and “out” on 1/8” mini jacks. Please refer to
the next section entitled SimLink™ for more details.
Then there is a 1/8” mini-jack input for use with
aftermarket infrared remote control receivers.
On the far right side is the main power switch (“0”=off,
“1”=on) and the IEC receptacle, labeled “AC Input” for
the included AC power cord. Connect the supplied AC
power cable to the IEC receptacle. Ensure that the AC
wall outlet you use has a functioning ground. For the
best sonic performance, it is preferable that you plug
your 280D directly into a dedicated AC outlet and avoid
using an extension cord.
* Please speak with your MOON Authorized Retailer about the
benefits of high quality cables for your system, and superior
quality AC wall outlet.
SimLink™
The main feature of SimLink™ on the Nēo 280D,
involves the “Standby” function. By pressing down and
holding the “Standby” button for 2 seconds on the
280D, all other MOON components connected via the
SimLink will go into “Standby” mode along with the
280D. The same logic applies when switching from
“Standby” to active mode. However, if your Nēo 280D is
equipped with the “MiND” Music Streamer, then the
SimLink™ offers many more features:, Mute, Standby,
Digital input selection, and Volume adjustments (with
MOON preamplifiers and integrated amplifiers) all via
the “MiND” app running on your Apple device.
9
280D Nēo Series
If you are using an external “MiND” Music Streamer with
your 280D you should make a SimLink™ connection
between the “MiND”s SimLink™ out and the 280D’s
SimLink™ in. When you press the X (play) button on the
“MiND” App, the 280D will automatically switch to the
“SPDIF 1” input. You can change the default for the
“MiND” as follows: Select the input that you want as the
new default for “MiND”, then press and hold the INPUT
(down) button for approximately 3 seconds; the
corresponding input LED. will blink two (2) times.
If you are using a MOON CD Transport or CD Player with
your 280D you should make a SimLink™ connection
between the “CD”s SimLink™ out and the 280D’s
SimLink™ in. The default input is the “AES/EBU” which
means that when you press the X (play) button on the
CD, the 280D will automatically switch to the “AES/EBU”
input. You can change the default for the “CD” as
follows: Select the input that you want as the new
default for “CD”, then press and hold the INPUT (up)
button for approximately 3 seconds; the corresponding
input LED. will blink two (2) times.
The connection rules for the SimLink™ are very
straightforward. You must always connect the supplied
cable between one component’s “SimLink™ Out” jack
and another component’s “SimLink™ In” jack. There is
no master component in a SimLink™ chain; no one
particular component operates as the main
communications controller. If you are using your Nēo
280D with an older MOON product such as a P-7, P-8 or
i-7, you will need to update the software of the older
product to allow for complete SimLink™ functionality.
Contact your retailer for further details.
Operating the 280D
We recommend leaving your Nēo 280D powered up at
all times to maintain optimal performance. When you
plan on being away for a few days, it may not be a bad
idea to power off your DAC.
10
Turning on your Nēo 280D for the first time
Prior to turning the DAC on for the first time, make sure
that every cable is properly connected to avoid any
problems. Flick the main rocker switch, located on the
rear panel, labeled “POWER” to the ‘1’ (on) position.
Next, briefly press the push button labeled “Standby”
located on the front panel. You will hear a very faint
click sound confirming that everything is in order. The
blue LED on the front panel will illuminate, indicating
that the 280D is now powered up and ready for use.
On and Off Sequence
To avoid having any annoying noises (ie. “thumps” and
“pops”) emanate from your speakers when powering
your 280D on or off, you should always power up your
280D before powering up your preamplifier, integrated
amplifier or power amplifier. As well, always power
down your 280D after powering down your
preamplifier, integrated amplifier or power amplifier.
Balanced Operation
When using an unbalanced interconnect, the audio
signal runs through both the center wire and the
shield/ground wire. Any noise picked up by this
interconnect (ie. nearby magnetic fields such as an AC
power cord) will be reproduced by both the
preamplifier and amplifier, then heard through the
loudspeakers. Conversely, a balanced interconnect has
three separate conductors; one for the ground and two
for the actual signal. These two signals are identical
except that one is 180 degrees out of phase with the
other. For example, when one conductor is carrying a
signal of +2 Volts, the other will be carrying a signal of –
2 Volts. When these two inverted signals on a balanced
line are output from the Nēo 280D, any noise picked up
by the interconnect will be eliminated since a
differential circuit amplifies only the difference between
these two signals: Noise on a balanced interconnect
will be equal on both conductors and therefore cancel
out.
Owner’s Manual
Remote Control Operation
The Nēo 280D Digital-to-Analog Converter uses the ‘CRM-2’ full-function
remote control (figure 6). It operates on the Philips RC-5 communication
protocol and is can be used with other MOON components.
The ‘CRM-2’ remote uses two AA batteries (included). To install them, simply
slide the back plate off in the direction of the arrow; insert the batteries in the
correct direction and then replace the back plate.
To engage the ‘CRM-2’ remote for use with the Nēo 280D, you must first
press the button labeled D/A.
The POWER button located on the upper left will switch the Digital-to-Analog
Converter to either ‘Standby’ or ‘On’ mode.
The 2 buttons labelled ◄ INPUT ► allow you to sequentially scroll, either
backwards or forwards, through all available inputs. For example, to switch
from “SPDIF 2” to “OPT 1” you may press either ◄ INPUT three (3) times or
INPUT ► five (5) times. Pressing and holding down either of these buttons
results in only a single change to the selected input.
The MUTE button turns off the output volume. Pressing the “Mute” button a
second time will reinstate the output volume level back to its current setting.
When your selected input is “BT” (Bluetooth) and you have a paired smart
device (iPhone, iPad, Android, etc.) that is playing music, you may be able to
use the (pause), X (play) (forward) and (backward) buttons on the
CRM-2 remote control to navigate the music stored on your smart device.
This is dependant on both the App and the smart device, as there may be
compatibility issues.
NOTE: The buttons labelled ◄ BAL ► don’t affect the operation of the 280D.

their respective SimLink™ ports (using a 1/8” mini-jack cable). When you launch the MiND App on your Apple
smart device and select this system’s ZONE, the 280D and 340i will both turn on. As well, the 280D will
automatically switch to the MiND input. To shut down the system, press “Off” for this ZONE in the MiND app.
Figure 5: Remote Operation with SimLink™ and 12 V Trigger
In figure 5 we have a Nēo 280D DAC connected to a Nēo 350P Preamplifier via their respective SimLink™ ports
(using a 1/8” mini-jack cable), and the 350P is connected to a Nēo 330A Amplifier via their respective 12V triggers
(also using a 1/8” mini-jack cable). When you turn on the 280D via remote control or by pressing & holding its
Standby button, both the 350P and 330A will turn on automatically. The same rule applies when you put the
280D into Standby mode.
