MOON by Simaudio
Unpacking
The MOON 340i integrated amplifier should be removed from its box with care.
The following accessories should be included inside the box with your integrated amplifier :
• AC power cable
• ‘‘CRM-3” remote control with two “CR-2032” batteries
• “SimLink™ cable with 1/8” mini plug terminations on each end
• This owner’s manual
• Warranty and product registration information (USA and Canada only)
Once the MOON 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.
The MOON 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;
Serial Number
Installation & Placement
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,youshould never place another component
directly on top of this integrated amplifier.
If you intend to use the MOON 340i’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.
Please write the serial number of your new MOON 340i in the space provided below for future reference.

07
Figure 1 : MOON 340i Front panel
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”; With all options
installed: “CD”, “A1”, “A2”, “PH”, “B1”, “D1”,
“D2”, “D3” and “D4”.
The front panel will look similar to Figure 1 (above). The large display window indicates the selected
inputsource. If your MOON 340i 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.
Front Panel Controls
These 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MOON
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.

MOON by Simaudio
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 MOON 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.

09
Figure 2: MOON 340i Optional Digital Inputs – connection examples
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.
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.

MOON by Simaudio
The MOON 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 MOON 340i for a wide variety of MC and MM cartridges.

Basic rule of thumb for typical MM cartridges
(default factory setting) :
Gain : 40dB
Curve : RIAA
Resistance : 47kΩ
Capacitance : 100pF
Basic rule of thumb for MC cartridges :
Gain : 60dB
Curve : RIAA
Resistance : 475Ω
Capacitance : 0pF
Please note that these abovementioned settings
are starting points, but in no way assure that
these are the best settings for any turntable/
cartridge setup.
Always power off the unit (by unplugging
the power supply) before making any change
of input settings via the bottom accessible
dipswitches.
Multiple combinations of settings can be applied
to optimize the input for the cartridge. Ideally
have the recommended settings from the
cartridge manufacturer on hand as a starting
point before any experimentation. And then
you may experiment around the recommended
values for best sound.
To adjust each of the four parameters (Gain,
Curve, Resistance and Capacitance), look at the
position of dipswitches drawn on the silkscreen
representations below the unit, and look for the
desired value of each parameter. Then using the
provided red stick as a tool, move the dipswitch
in the position that corresponds to the desired
value.

Rear Panel Connections
Figure 6 : MOON 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 MOON 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 the CD, A1 and A2 inputs.
The MOON 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 MOON 340i only asapreamplifier. Keep in
mind that the output level is variable and adjusted
by the 340i’s volume control.
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 MOON 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
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.

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 (play) button on the 260D
willcause the 340i to automatically switch to the input labelled ‘B1’. 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.
A second 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 the “MiND” Music Streamer; When you press the (play) button
onthe “MiND” App, the 340i will automatically switch to the input labeled “A1”. You can change this 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.
If your 340i includes the “DAC” option, then the default input for the MiND is the ‘D2” input; When you press
the(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.
The MOON 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.

Operating the MOON 340i
We recommend leaving your MOON 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
The MOON 340i Integrated Amplifier uses the CRM-3
full-function remote control (figure 7). It operates onthePhilips
RC-5 communication protocol and can be used with other
Simaudio MOON components.
The CRM-3 remote uses two CR-2032 batteries (included).
Toinstall them, simply remove the two screws fromtheslidable
lower section of the back plate, insert thebatteries
inthecorrect direction and then replace theback plate.
To engage the CRM-3 remote for use with the MOON 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 buttons labelled BAL don’t affect
theoperation of the 340i.

Remote operation with multiple MOON components
In figure 6 we have a 180 MiND Music Streamer and a MOON 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.
In figure 7 we have a MOON 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.
