case you’re required to transport this product. The
customized packaging is specially designed to
protect the 340i from any potential damage during
transit.

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 the support
section of our website..

Note: Apple-based computers don’t require
this driver.

Front Panel Controls

Figure 1: Nēo 340i 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.

Basic Unit: “CD”, “A1”, “A2” and “A3”

All options installed: “CD”, “A1”, “A2”, “PH”, “B1”, “D1”, “D2”, “D3” and “D4”

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 (►):

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.

340i Integrated Amplifier

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.

The “A2” input can be configured as a

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
adjusting the volume on the 340i will have no effect
whatsoever when the “A2” input is selected. To put
the “A2” input into

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 or external hard drive to
to the “D4” input.

340i Integrated Amplifier

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.

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

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

Resistance Loading:

There are two (2) different settings available for
setting the resistive load; 100Ω and 47kΩ which 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.

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.

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 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

using a MC cartridge, you should insert the supplied
jumpers into each of the two left-most sockets
labeled MC.

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

Rear Panel Connections

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 Nēo 340i, 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.

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
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

optional phono section

,

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 only as a preamplifier. Keep in
mind that the output level is variable and adjusted
by the 340i’s volume control.

340i Integrated Amplifier

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 bi­directional 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 260D to the 340i via the
SimLink™, pressing the X (play) button on the
260D 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 260D 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.

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 buttons labelled ◄ BAL ► don’t affect the operation of the 340i.

Figure 6: Remote Operation with SimLink™

In figure 6 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 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 7: Remote Operation with 12V Trigger

In figure 7 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.
