The “A2” input can be configured as a ‘pass-through’ which bypasses the i 3.3’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 i

Optional Phono Section 9

MOON i 3.3 Integrated Amplifier

Optional Phono Section (Cont’d)

Internal Settings

There are three (3) types of settings available on the optional phono section of the MOON i 3.3 Preamplifier; 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 MOON i 3.3 Preamplifier prior to changing any of the
following input settings.

There are a total of six (6) screws, located on the top of the chassis, that you must remove using the included allen-key. 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 i

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.

In the event that you’re using a moving magnet (MM) cartridge, 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.

In the event that you’re using a MM cartridge, 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;

an MM cartridge as this will overload the preamplifier

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 MOON i

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 magneti c fields such as an AC power cord) will be repr oduced by both the preamplifier
and amplifier, then heard through the loudspeakers. Con versely, a balanced interconnect has three separate conductors; o ne for
the ground and two for the actual signal. These tw o signals are identical except that one is 180 degrees out o f 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 MOON i
eliminated since a differential circuit amplifies only the difference betw een these tw o signals: Noise on a b alanced interconn ect will
be equal on both conductors and therefore not be processed.

3.3 optional balanced input takes full advantage of the benefits of balanced circuitry:

Rear Panel Connections

Figure 4: MOON i 3.3 Rear panel

The rear panel will look similar to Figure 4 (above). There are four (4) pairs of single-ended analog inputs on RCA connectors
labeled CD, A1, A2 and A3/P. The left channel inputs are located on top and the corresponding right channel inputs are
located directly below. In the event that your MOON i
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 MOON i 3.3 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 i
designated for output to a power amplifier with single-ended RCA inputs in the event that you wish to use your MOON i
as a preamplifier only. Keep in mind that the output level is variable and adjusted by the i

In the event that your MOON i 3.3 is equipped with the aforementioned 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.

3.3 is equipped with the aforemen tioned optional phono section, the

3.3’s volume control. The ‘VAR’ output is

MOON i 3.3 Integrated Amplifier

Rear Panel Connections (cont’d)

In the event that your MOON i 3.3 is equipped with the aforementioned 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 t he 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 i

The MOON i 3.3 is equipped with a pair of gold-plated binding posts. The right channel speaker output is located above the
analog inputs. The left channel speaker output is located to the right of the digital inputs. Connect your loudspeakers, with the
cables of your choice, to these binding posts, paying attention to respect the polarity (“+” , “-” ) of the output.

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.

You will notice that all RCA input and output connectors on the rear panel have been color coded: ‘white’ for the left channel
and ‘red’ for the right channel. A poor contact will degrade the signal substantially, and plugs and sockets should all look clean
and free of dirt and corrosion. The easiest way to clean them is to remove the cables from their sockets and push them back
in again. This procedure requires that your Integrated Amplifier and the rest of your components be completely turned off.
Not heeding this warning may result in serious damage to your equipment. Special contact cleaning fluids and enhancers
should not be used, as they deposit a difficult to remove residue which degrades the performance of your components.

MOON i 3.3 Integrated Amplifier

SimLink™

The SimLink™ provides communication features between various MOON components. For example, if you were to connect
the CD

3.3 to the i 3.3 via the SimLink™, pressing the X (play) button on the CD 3.3 will cause the i 3.3 to automatically

switch to the input labeled ‘CD’. A second feature of SimLink™ involves the “Standby” function. By pressing down and holding
the “Standby” button for 2 seconds on the either the CD
applies when switching from “Standby” to active mode.

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 will not function. Also, there is no master
component in a SimLink™ chain; no one particular component operates as the main communications controller.

We recommend that you leave your MOON i 3.3 Integrated Amplifier powered up at all times to for optimal performance. In
the event that you plan to be away from your home for a few days, powering off the Integrated Amplifier may not be a bad
idea. Once fully “broken-in”, please keep in mind that your i
peak performance after you’ve powered it up again.

Making the AC Connection: Connect the supplied AC power cable to the IEC receptacle, located on the rear panel of
the integrated amplifier’s chassis. Ensure that the AC wall outlet you use has a functioning ground. For the best sonic
performance, it is preferable that you plug your MOON i 3.3 directly into a dedicated AC outlet and avoid using an extension
cord. In order to obtain the maximum performance from your audio system, we strongly recommend that the detachable
power cord not come into physical contact with any of the interconnect and speaker cables running to and from your i
the event that this can’t be avoided, you should ensure that any cables coming into contact with each other are crossed at a
ninety degree angle to minimize the contact area.

Turning on your MOON i 3.3 for the first time: Prior to turning the integrated amplifier on for the first time, make
sure that every cable is properly connected to avoid any problems. Then turn on your integrated amplifier in the following
manner:

1) Flick the main rocker switch labeled “POWER” to the ‘1’ (on) position on the rear of the i

2) Press the push button labeled “Standby” on the i

On and Off Sequence: To avoid having any annoying noises (ie. “thumps” and “pops”) emanate from your speakers
when powering your i

1) Always power up your i 3.3 integrated amplifier after powering up your source component(s).
