damage during transit.
Please write the serial number of your new Nēo 350P in the space provided below for future reference.
Serial Number
Installation & Placement
The Nēo 350P 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
preamplifier’s performance and reliability. As well, it
should be placed on a solid level surface. The 350P uses
toroidal transformers; even though they are well
shielded, you should not place the preamplifier too
close to source components sensitive to EMI, such as a
turntables.
If you intend to use the Nēo 350P’s USB input
connection (PCM or DSD) with a Windows-based
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.

Front Panel Controls
Figure 1: Nēo 350P Front panel
The front panel will look similar to Figure 1 (above). The large display window indicates the selected input source.
If your Nēo 350P includes the digital input option, additional information will appear in the display window. Refer
to the section entitled “Optional Digital Inputs” on page 9 for further details..
The “Standby” button disengages the input section
from the rest of the 350P’s circuitry. When in “Standby”
mode all audio circuitry remains powered up to help
maintain optimal performance. When switching back
from “Standby” to the “on” mode, the blue LED directly
above the display window will illuminate, As well, the
current ‘input’ will be memorized from the previous
listening session. The blue indicator LED turns off when
the 350P is in “Standby” mode.
The “MP” button (for Media Player) has its input
connection located next to the headphone jack for easy
access. It uses a 1/8” mini-jack connector which is the
most common type of connection found on portable
media players. When selected, the corresponding red
LED, located to the left of the button, will illuminate.
When the “MP” input is in use the display window
automatically turns off. The “Display” button allows you
to turn the digital display on and off.
The two (2) buttons labeled ◄INPUT ►allow you to
sequentially scroll, either forward (►) or backward (◄)
through all of the available inputs. Depending on the
installed options, the order of the inputs is as follows
going forward (►): Basic Unit: “CD”, “A1”, “A2”, “A3”, “B1”
and “B2”; All options installed:“CD”, “A1”, “A2”, “PH”,
“B1”, “B2”, “D1”, “D2”, “D3” and “D4”
The above abbreviations correspond to the labeling of
the rear panel inputs. By default the “CD” input is
intended for use with a CD Player, however you can
connect another type of source component to it. “A1”,
“A2”, “A3”, “B1” and “B2” are intended for use with any
type of source component that outputs an analog
signal: “CD”, “A1”, “A2” and “A3” for single-ended
sources using RCA connectors; “B1” and “B2” for
balanced sources using XLR connectors. If you have
installed the optional phono section, the “A3” input is
replaced by “PH”. If you have installed the digital input
option, “D1”, “D2”, “D3” and “D4” will appear after “B2”.
The optional inputs only appear if they are installed.
The “Monitor” button provides for a dedicated loop to
be used with either a component that can record &
playback (Cassette Deck, DAT, CD-Recorder, etc.) or a
signal processor such as an equalizer. Pressing this
button allows you to 1) monitor the recording as it
occurs on the recording device or 2) engage the effects
of the signal processor. The monitor component’s
outputs must be connected to the 350 P’s “Monitor In”
and its inputs must be connected to the 350P’s
“Monitor Out”. The monitor output level is fixed and
independent of the 350P’s volume setting. The LED to
the left of the display window will illuminate when the
“Monitor” function is engaged.
The “Mute” button mutes the output signal to the
headphone jack, as well as both the fixed and variable
line output connectors (refer to the section entitled
“Rear Panel Connections” for further details). Pressing
the “Mute” button a second time will reinstate the
volume back to its previous level. When the output

Owner’s Manual
9
signal is muted, the red LED to the right will repeatedly
flash on and off.
The “A2” input can be configured as a ‘pass-through’
which bypasses the 350P’s gain control section,
allowing you to control the gain setting via the
connected source component’s own volume control – a
home theater processor for example; In other words,
this input operates like the input of a power amplifier. In
‘pass-through’ mode, adjusting the volume on the
350P will have no effect whatsoever when the “A2”
input is selected. To put the “A2” input into ‘pass-
through’ mode, press and hold down the “Monitor”
button for approximately 2 seconds while on the “A2”
input. The front panel display will change from “A2” to
“HT”. To reconfigure the “A2” input to function like the
other inputs, repeat the this procedure. Powering down
the 350P via the rear panel rocker switch will
automatically reset the the “A2” to the factory default
‘normal’ mode.
The rotary “Volume” control determines the output
level. The volume control has an embedded red LED to
indicate its actual position.
The “Phones” jack is used for connecting a pair of stereo
headphones to the Nēo 350P. The input connector is a
standard ¼” stereo jack. When a pair of headphones are
used with the 350P,the output signal will continue to
be sent to the amplifier(s) connected to the 350P.
Optional Digital Inputs
The Digital Input option includes four (4) separate
inputs: “D1” uses an optical Toslink connector, “D2” and
“D3” use S/PDIF on an female RCA connector and “D4”
uses a type-B USB connector. The “D1” is intended for
use with a source equipped with a TosLink digital
output such as a satellite dish receiver; The “D2” and
“D3” inputs are intended for use with a source equipped
with a S/PDIF digital output such as a DVD player, music
server or disc transport. The “D4” input is for use with a
computer equipped with a USB connector and music
player software such as iTunes or Winamp; you cannot
connect a USB flash drive or external hard drive to the
“D4” input.
When you select one of the digital inputs as described
in the aforementioned section, the display window will
show which of the four digital inputs is selected. At the
same time, the right side of the display window will
initially show four dashes as follows “----” which indicate
that the 350P is in the process of locking onto the
external digital signal – this may take several seconds.
When the 350P successfully locks onto the digital
signal, the four dashes will be replaced by the sampling
rate of this digital signal. When the signal cannot be
locked onto, “----” remains in the display window. The
optional digital-to-analog circuit option inside the Nēo
350P is capable of processing the following sampling
rates: 32.0kHz, 44.1kHz, 48.0 kHz, 88.2kHz, 96 kHz,
176.4kHz and 192kHz.

Optional Phono Section
The Nēo 350P Preamplifier features an optional MC/MM
phono section that may be installed only by your MOON
Authorized Dealer or at the Simaudio factory. This
phono card is a very high quality design, providing
adjustments for both capacitance and resisitance
loading, as well as gain level. This flexibility allows you
to optimize the 350P for a wide variety of MC and MM
cartridges.
Circuit Board Layout:

Internal Settings
We strongly recommend that you ask your MOON Authorized Dealer to make these adjustements. If you
decide to do this on your own, any damage cause to this component, including from static discharge, will
not be covered under warranty.

Owner’s Manual
11
There are three (3) types of settings available on the
optional phono section of the Nēo 350P; Capacitance
loading, Resistance loading, and Gain level. Each setting
is adjustable through the use of jumpers. For each type
of setting, there are 2 banks of jumpers – one each for
the left and right channels. This is the result of the
phono section’s genuine mirror-image circuit design
which yields exceptional stereo separation.
Always disconnect all audio connections and the AC
power cord of your Nēo350P prior to changing any of
the following input settings.
There are six (6) screws, located on the top of the
chassis, that you must remove using a phillips head
screw driver. Once these screws are removed, carefully
lift off the chassis cover. Once the cover is removed, you
are ready to make all of the necessary internal
adjustments to the 350P phono module to achieve
optimal sonic performance.
Resistance Loading:
There are two (2) different settings available for setting
the resistive load; 100Ωand 47kΩwhich are
represented by jumper sockets R12 for the left channel
and jumper socket R29 for the right channel (refer to
figure 2 – section labeled “LOADING”). The factory
default setting is 47kΩ, therefore both jumpers will be
found in each of the two left most sockets.
For moving magnet (MM) cartridges, it is recommended
that you leave the jumpers inserted in the factory
default setting of 47kΩ. Conversely, if you’re using a
moving coil (MC) cartridge, you should use the 100Ω
jumper settings by simply inserting the supplied
jumpers into each of the two right-most sockets of
jumpers R12 and R29.
Capacitance Loading:
There are two (2) different settings available for the
capacitive load; 0pF and 100pF which are represented
by jumper sockets C9 for the left channel and jumper
sockets C17 for the right channel (refer to figure 2 –
section labeled “LOADING”). The factory default setting
is 100pF for a moving magnet cartridge, therefore both
jumpers will be found in each of the two right most
sockets.
For MM cartridges, it is recommended that you leave
the jumpers inserted in the factory default setting of
100pF. Conversely, if you’re using a MC cartridge, you
should use the 0pF jumper settings by simply inserting
the supplied jumpers into each of the two left-most
sockets of jumpers C9 and C17.
Gain Level:
There are two (2) different settings available for gain
level. They are 40dB for MM cartridges and 60dB for MC
cartridges, which are represented by jumper socket J18
for the left channel and jumper socket J24 for the right
channel (refer to figure 2 – section labeled “GAIN”). The
factory default setting is for a MM cartridge , therefore
both jumpers will be found in each of the two right
most sockets labeled MM; It is highly recommended
that you do not use the jumpers labeled MC for an MM
cartridge as this will overload the 350P. When using a
MC cartridge, you should insert the supplied jumpers
into each of the two left-most sockets labeled MC.

Rear Panel Connections
Figure 4: Nēo 350P Rear panel
The rear panel will look similar to Figure 2 (above). There are two (2) pairs of balanced analog inputs on XLR
connectors labeled “B1” and “B2” with their respective left and right channel connections beside each other.
Immediately below are four (4) pairs of single-ended analog inputs on RCA connectors labeled CD, A1, A2/HT and
A3/PH. The RCA input and output connectors on the rear panel have been color coded: ‘white’ for the left channel
and ‘red’ for the right channel. If your Nēo 350P is equipped with the optional phono section, the input labeled
‘A3/P’ must be used to connect your turntable interconnect leads to this preamplifier. If you don’t have the
optional phono section installed, then this input can be used in the same way as CD, A1 and A2 inputs. This
preamplifier is also equipped with a single-ended monitor loop; the input and output connectors for each channel
are located to the right of the four pairs of single-ended analog inputs.
The Nēo 350P premplifier has three pairs of outputs: 1
pair of balanced XLR’s and 2 pairs of single-ended RCA’s
labeled ‘FIX’ and ‘VAR’, located next to the monitor
inputs and ouputs. The balanced outputs are
designated for output to a power amplifier equipped
with balanced inputs.The ‘FIX’ output is intended as an
input to a recording device such as a cassette tape deck
or CD-Recorder Player. Keep in mind that the output
level is fixed and cannot be adjusted by the 350P’s
volume control. The ‘VAR’ output is designated for
output to your power amplifier(s) with single-ended
RCA inputs. If the power amplifier(s) you’re connecting
the 350P to use balanced inputs, its highly
advantageous to use the 350P’s XLR outputs. This will
provide you with an even better signal-to-noise ratio.
Don’t hesitate to use high quality interconnect cables*.
Poor quality interconnect cables can degrade the overall
sonic performance of your system.
For Nēo 350P’s equipped with the digital input option,
you will find 4 digital inputs labeled D1, D2, D3 and D4.
The D1 input is on an optical Toslink connector; both
the D2 and D3 inputs are on a S/PDIF connector; the D4
input is on a USB type B connector.
Below the area reserved for the optional digital inputs
are a series of input/output connectors for custom type
installations: From left to right there 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. Next, there’s a 1/8” mini-jack
input for use with aftermarket infrared remote control
receivers. Then there’s a 12V trigger output on a 1/8”
mini-jack that can power up a connected component
(with a 12V trigger input) at the same time that the
350P is powered up. Next, there’s a full-function bi-
directional RS-232 port for custom integration or
automation on a DB9 connector. Finally on the far right
side is the “AC Fuse” socket cover, the main power
switch (“0”=off, “1”=on) and the IEC receptacle, labeled
“AC Power” for the included AC power cord.
Connect the supplied AC power cable to the IEC
receptacle, located on the preamplifier’s rear panel.
Ensure that the AC wall outlet you use has a functioning
ground. For the best sonic performance, it is preferable
that you plug your 350P directly into a dedicated AC
outlet and avoid using an extension cord. If you have
the time and willingness, consider installing a superior
quality AC wall outlet such as a hospital grade Hubbell*.
* Please speak with your MOON Authorized Retailer about the
benefits of high quality cables for your system, and superior
quality AC wall outlet.

Owner’s Manual

Balanced Operation
The Nēo 350P includes two (2) balanced line-level
inputs and one (1) balanced preamplifier output on XLR
connectors. The “B1” and “B2” inputs use a fully
balanced differential circuit, intended for use with
source components that output a fully balanced
differential signal. The Nēo 350P balanced inputs and
outputs takes full advantage of the benefits of balanced
circuitry:
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 +5 Volts, the other will be carrying a signal of –
5 Volts. When these two inverted signals on a balanced
line are output from the Nēo 350P, 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.
SimLink™
The SimLink™ provides communication features
between various MOON components. For example, if
you were to connect the Nēo 260D to the 350P via the
SimLink™, pressing the X(play) button on the Nēo
260D will cause the 350P to automatically switch to the
input labeled ‘CD’. You can change this default setting
as follows: Select the input that you want as the new
default for CD, then press and hold the ◄INPUT (left)
button until the front panel display begins to flash on
and off.
Another feature of SimLink™ involves the “Standby”
function. By pressing down and holding the “Standby”
button for 2 seconds on the either the Nēo 260D or
350P, both units will go into “Standby” mode. The
same logic applies when switching from “Standby” to
active mode.
If you are using the “MiND” Music Streamer and an
external digital-to-analog converter (DAC), you must
make a SimLink™ connection between the “MiND”s
SimLink™ out and the 350P’s SimLink™ in. The ‘A1’ input
is the default input for your external DAC’s analog
outputs; When you press the X(play) button on the
“MiND” App, the 350P will automatically switch to the
input labeled ‘A1’. If your 350P includes the “DAC”
option, then the default input for the MiND is the ‘D2”
input; When you press the X(play) button on the
“MiND” App, the 350P will automatically switch to the
input labeled ‘D2’. You can change these default
settings for the “MiND” as follows: Select the input that
you want as the new default for “MiND”, then press and
hold the “MP” button until the front panel display
begins to flash on and off.
The connection rules for the SimLink™ are very basic.
You must always connect the supplied cable between
one component’s SimLink™ Out jack and another
component’s SimLink™ In jack. If you inadvertently
connect the cable between either two SimLink™ In or
two SimLink™ Out jacks, the SimLink™ communication
feature may not function. Also, there is no master
component in a SimLink™ chain; no one particular
component operates as the main communications
controller.

Operating the Nēo 350P
We recommend leaving your Nēo 350P 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 preamplifier. Please keep in mind
that once fully “broken-in”, your 350P requires several
hours of operation before reaching optimal
performance after powering it up again.
Turning on your Nēo 350P for the first time
Prior to turning the preamplifier 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 to place your 350P in to standby mode.
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 350P 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 350P on or off, you should always power up your
350P prior to powering up your amplifier. As well,
always power down your 350P after powering down
your amplifier(s).

Owner’s Manual

Remote Control Operation
The Nēo 350P Preamplifier uses the ‘CRM-2’ full-function remote control
(figure 3). It operates on the Philips RC-5 communication protocol and is can
be used with other Simaudio 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 350P Preamplifier, you
must first press the button labeled AMP.
The POWER button located on the upper left will switch the Preamplifier to
either ‘Standby’ or ‘On’ mode.
The DISPLAY button turns the front panel display on and off
The 2 buttons labeled ◄INPUT ►allow you to sequentially scroll, either
backwards or forwards, through all available inputs. For example, to switch
from the “A3” to the “CD” input, press ◄INPUT three (3) times. To switch from
the “CD” to the “A3” input, press INPUT ►three (3) times. Pressing and
holding down either of these buttons results in only a single change to the
selected input.
The 2 buttons labeled ▼VOL ▲allow you to control the volume level. Pressing
▼VOL results in a decrease in the volume level; Pressing VOL ▲results in an
increase in the volume level. You may either press and hold these buttons
down or press them briefly to make volume adjustments.
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.

Remote operation with multiple MOON components
Figure 6: Remote Operation with SimLink™ and 12V Trigger
In figure 6 we have a 180 MiND Music Streamer connected to a Nēo 350P Preamplifier via their respective
SimLink™ ports (using a 1/8” mini-jack cable), and the 350P connected to a 330A Amplifier via their respective 12V
triggers (also using a 1/8” mini-jack cable). When you launch the MiND App on your Apple smart device (full list on
the MiND page of our website) and select this system’s ZONE, the 180 MiND will turn on, as will both 350P and the
330A; The 350P will automatically switch to the “MiND” assigned input, as described previously in the SimLink™
section. To shut down the system, press “Off” for this ZONE in the MiND app.
Figure 7: Remote Operation with 12V Trigger
In figure 7 we have a Nēo 350P Preamplifier and 330A Amplifier connected together via their respective 12V
triggers; The 12V trigger output on the 350P is connected to the 12V trigger input on the 330A (using a 1/8” mini-
jack cable). When you turn on the 350P via remote control (or its Standby button), the 330A will turn on
automatically. The same rule applies when you put the 350P into Standby mode.
