Please write the serial number of your new Simaudio Nēo 350P in the space provided below for future eference.
Serial No.: ________________
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 with a Windows-based computer,
you will need to install our USB HD 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: Nēo350P 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 8 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.

350P Preamplifier
____________________________________________________________________________________

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 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.

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.
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 R9 for the left
channel and jumper socket R24 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 100Ωjumper settings by simply
inserting the supplied jumpers into each of the two
right-most sockets of jumpers R9 and R24.
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 J17 for the left channel and jumper
socket J22 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: Nēo350P 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.

350P Preamplifier
____________________________________________________________________________________
13
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.
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 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).

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.
NOTE: The buttons labelled ◄BAL ►don’t affect the operation of the 350P.

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.
