Unpacking
The Nēo 340i Integrated Amplifier is heavy component and should be removed from its box with care. We strongly advise
that you seek another person to help lift the amplifier out of its box, and place it in its final location.
The following accessories should be included inside the box with your amplifier:
9 AC power cable
9 ‘CRM-2’ remote control with two ‘AA’ batteries
9 This owner’s manual
9 Warranty and product registration information (USA and Canada only)
Once the Nēo 340i is unpacked, inspect it thoroughly and report any damage to your dealer immediately. We suggest that
you keep all of the original packaging, storing it in a safe, dry place in case you’re required to transport this product. The
customized packaging is specially designed to protect the 340i from any potential damage during transit.
Please write the serial number of your new Simaudio Nēo 340i in the space provided below for future reference.
Serial No.: ________________
Installation & Placement
The Nēo 340i Integrated Amplifier is both powerful and heavy. It requires reasonable ventilation to maintain an optimum and
consistent operating temperature, especially since it will radiate heat when driven hard. Consequently, it should be placed in a
location with empty space around it for proper heat dissipation. You should never place another component on top of this
integrated amplifier. As well, it should be placed on a solid level surface. You should avoid placing it near a heat source or
inside a closed cabinet that is not well ventilated as this could compromise the amplifier’s performance and reliability. The
340i uses a large toroidal transformer in its power supply; even though it is well shielded, you should not place this
integrated amplifier too close to source components sensitive to EMI, such as turntables, phono preamplifiers and CD Players.
Finally, y
ou should never place another component directly on top of this integrated amplifier.
If you intend to use the Nēo 340i’s USB input connection with a Windows-based computer, you will need to
install our USB HD driver, which can be downloaded from our website:
http://www.simaudio.com/downloads.htm
Note: Apple-based computers don’t require this driver.

340i Integrated Amplifier
Front Panel Controls
Figure 1: Nēo340i Front panel
The front panel will look similar to Figure 1 (above). The large display window indicates the selected input source. If your Nēo
340i 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 340i’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 340i is in “Standby” mode.
The “MP” button (for Media Player) has its corresponding input connection located on the right side of the front panel 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” and “A3”
All options installed: “CD”, “A1”, “A2”, “PH”, “B1”, “D1”, “D2”, “D3” and “D4”
The above abbreviations correspond directly 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” and “A3” are intended for
use with any type of source component that outputs analog signal. If you have installed the optional phono section, the “A3”
input is replaced by “PH”. If you have installed the balanced input option, “B1” will appear after the “A3” / ”PH” input. Finally,
if you have installed the digital input option, “D1”, “D2”, “D3” and “D4” will appear after either “B1” (if you have the balanced
option) or “A3” / ”PH”. The optional inputs only appear if they are installed.
The “Spk off” button turns off the output signal only to the loudspeakers connected to the Nēo 340i. This feature is very
useful when using headphones. When this function is engaged, the red LED located to the right will illuminate.
The “Mute” button mutes the output signal to the loudspeaker terminals, 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.

340i Integrated Amplifier
Front Panel Controls (Cont’d)
The “A2” input can be configured as a ‘pass-through’ which bypasses the 340i’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
340i 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 “Mute” 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 340i 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 340i. The input connector is a standard ¼”
stereo TRS jack. When a pair of headphones are used with the 340i,the loudspeakers will still receive an output signal.
However, you should use the aforementioned “Spk off” button for private listening.
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 to the “D4” input.
Figure 2: Nēo 340i Optional Digital Inputs – connection examples
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 340i is in the process of locking onto the external digital signal – this may take several
seconds. When the 340i 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 340i is capable of processing the following sampling rates: 32.0kHz, 44.1kHz, 48.0 kHz,
88.2kHz, 96 kHz, 176.4kHz and 192kHz.

340i Integrated Amplifier
Optional Phono Section
The Nēo 340i Integrated Amplifier 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 340i for a wide variety of
MC and MM cartridges.

Optional Phono Section (Cont’d)
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 340i; 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 Nēo 340i 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 340i 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 340i
. When using a MC cartridge, you should insert the supplied jumpers into
each of the two left-most sockets labeled MC.

340i Integrated Amplifier
Optional Balanced Input
The balanced input option provides for one additional line-level input on an XLR connector. The “B1” input uses a fully
balanced differential circuit and is intended for use with a source component that outputs a fully balanced differential signal.
The Nēo 340i optional balanced input 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 +10 Volts, the other will be carrying a signal of –10 Volts. When
these two inverted signals on a balanced line are output from the Nēo340i, 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.
Rear Panel Connections
Figure 4: Nēo 340i Rear panel
The rear panel will look similar to Figure 2 (above). There are four (4) pairs of single-ended analog inputs on RCA connectors
labeled CD, A1, A2 and A3/P. 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 340i is equipped with the
optional phono section , the input labeled
‘A3/P’ must be used to connect your turntable interconnect leads to this integrated amplifier. 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.
The Nēo 340i integrated amplifier also has two pairs of non-amplified outputs labeled ‘FIX’ and ‘VAR’, located next to the
A3/P input. 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 340i’s volume control. The ‘VAR’ output is
designated for output to a power amplifier with single-ended RCA inputs if you wish to use your Nēo 340i as a preamplifier
only. Keep in mind that the output level is variable and adjusted by the 340i’s volume control.
For Nēo 340i’s equipped with the balanced input option , you will find one pair of XLR balanced inputs to the right of these
non-amplified outputs. These are intended to be used with a source component that outputs a balanced signal.
For Nēo 340i’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.

Rear Panel Connections (cont’d)
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 340i 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.
Don’t hesitate to use high quality interconnect cables*. Poor quality interconnect cables can degrade the overall sonic
performance of your system.
The Nēo 340i is equipped with a pair of gold-plated binding posts. Connect your speakers, with the cables of your choice, to
the 340i’s speaker binding posts. Take care to respect the polarity (“+” , “-” ) of the outputs. Once again, don’t hesitate to
use high quality speaker cables*. Poor quality speaker cables can degrade the overall sonic performance of your system.
Connect the supplied AC power cable to the IEC receptacle, located on the amplifier’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 340i 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.
SimLink™
The SimLink™ provides communication features between various MOON components. For example, if you were to connect
the 360D to the 340i via the SimLink™, pressing the X(play) button on the 360D will cause the 340i 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 360D or 340i, 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 340i’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 340i will automatically switch to
the input labeled ‘A1’. If your 340i 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 340i 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.

340i Integrated Amplifier
Operating the 340i
We recommend leaving your Nēo 340i 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 amplifier. Please keep in mind that once fully “broken-in”,
your 340i requires several hours of operation before reaching optimal performance after powering it up again.
Turning on your MOON 340i for the first time
Prior to turning the amplifier 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. The blue LED on the front
panel will blink for up to 10 seconds while it achieves standby mode. When it stops blinking and is not illuminated, your 340i
is in 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 340i 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 340i on or
off, you should always power up any source components prior to powering up your 340i. As well, always power down your
340i prior to powering down any source components.
Remote Control Operation
Figure 5: Remote Operation with SimLink™
In figure 5 we have a 180 “MiND” Music Streamer and a Nēo 340i Integrated Amplifier connected together via their
respective SimLink™ ports. The SimLink™ output on the 180 “MiND” is connected to the SimLink™ input on the 340i (using a
1/8” mini-jack cable). When you launch the MiND App on your smart device (iPad, iPhone, Android Device) and select this
system’s ZONE, both the 180 “MiND” and the 340i will turn on, with the 340i automatically switching 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 6: Remote Operation with 12V Trigger
In figure 6 we have a Nēo 340i Integrated Amplifier (used either as ONLY a preamplifier or in a bi-amping configuration) and
330A Amplifier connected together via their respective 12V triggers; The 12V trigger output on the 340i is connected to the
12V trigger input on the 330A (using a 1/8” mini-jack cable). When you turn on the 340i via remote control (or its Standby
button), the 330A will also turn on. The same rule applies when you put the 340i into Standby mode.

340i Integrated Amplifier
Remote Control Operation (cont’d)
The Nēo 340i Integrated Amplifier uses the ‘CRM-2’ full-function remote control
(figure 7). 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 340i Integrated Amplifier,
you must first press the button labeled AMP.
The POWER button located on the upper left will switch the integrated amplifier to
either ‘Standby’ or ‘On’ mode.
The DISPLAY button turns the front panel display on and off
The 2 buttons labelled ◄INPUT ►allow you to sequentially scroll, either
backwards or forwards, through all six (6) available inputs. For example, to switch
from the “CD” to the “VIDEO” input you may press either ◄INPUT three (3)
times or 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 labelled ▼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 2 buttons labelled ◄BAL ►don’t affect the operation of the 340i.
