MOON 300 D v.2 Digital-to-Analog Converter
Introduction
Your MOON 300 D DAC incorporates many significant design features to achieve its “world class” level of performance. This
is an abbreviated list of the more important features:
Over-sized power supply with 8 stages of voltage regulation
Internal upsampling which uses 24-bit/352.8kHz processing.
BurrBrown PCM1793 high-resolution 24-bit/192-kHz Digital-to-Analog Converter and 8X oversampling digital filter
All inputs accept a signal up to 24-bit/192kHz resolution
IR input for external control.
Asynchronous Sample Rate Converter for exceptionally low intrinsic jitter levels
Single-ended RCA and Balanced XLR analog outputs
Advanced analog signal path using a DC servo circuit and proprietary analog filter
Pure copper circuit board tracings with extremely low impedance characteristics.
Extremely rigid chassis construction to minimize the effects of external vibrations.
Accurate matching of the very finest high quality electronic components in a symmetrical circuit design.
Designed to be powered up at all times for optimal performance.
Low operating temperature for a longer than normal life expectancy.
Installation & Placement
The MOON 300 D requires reasonable ventilation to maintain an optimum and consistent operating temperature. As a result,
it should be placed in a location with empty space around it for proper heat dissipation. As well, it should be placed on a solid
level surface. You should avoid placing it near a heat source as this could compromise the DAC’s performance and reliability.
The 300 D uses a toroidal transformer; even though it is well shielded, you should not place the player too close to source
components sensitive to EMI, such as turntables and phono preamplifiers. You should never place another component directly
on top of this DAC.
If you intend to use the MOON 300D v.2’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.

MOON 300 D v.2 Digital-to-Analog Converter
Front Panel Controls
Figure 1: MOON 300 D Front panel
The front panel will look similar to Figure 1 (above). The “Standby” button is located in the lower left corner and toggles the
MOON 300 D between standby mode and operational mode. When in “Standby” mode, the 300 D’s output signal is muted,
however, all digital and analog audio circuitry remains powered up to help maintain optimal performance. As well, the blue
LED on the 300 D will no longer be illuminated when the player is in “Standby” mode.
Directly above the “Standby” button is a vertical array of six (6) red LED’s to indicate the sampling frequency of the digital
input signal: 192 kHz, 176.4 kHz, 96 kHz, 88.2 kHz, 48 kHz and 44.1kHz. Only when the MOON 300 D has successfully locked
onto an input signal will one of these LED’s illuminate.
The “Input” button, located in the lower right corner, allows you to sequentially scroll through the four (4) different digital
inputs; each time you press the “Input” button, the 300 D scrolls to the next input. Directly above the “Input” button are four
(4) red LED’s to indicate the selected input:
D1
D2
D3
D4
TosLink
S/PDIF
S/PDIF
USB
In the event that the 300 D cannot successfully lock onto the digital signal from the selected input, a sampling frequency LED
will not illuminate. This may be the result of i) no digital source component connected to the selected input ii) a faulty digital
audio cable between 300 D and your digital source component, your digital source iii) your digital source component not
being powered up or iv) your digital source component malfunctioning.
When you put the MOON 300 D into “Standby”mode, the currently selected input will remain the same when you put the unit
back into operational mode. However, when the AC power is interrupted, the 300 D will automatically default to the “D1”
input upon powering up.

MOON 300 D v.2 Digital-to-Analog Converter
Rear Panel Connections
Figure 2: MOON 300 D Rear panel
The rear panel will look similar to Figure 2 (above). The top left section has four (4) digital inputs – “D1” is an optical Toslink
connector and is intended for use with devices equipped with a digital Toslink output such as a DVD player or digital satellite
recevier; Both “D2” and “D3” are S/PDIF on a coaxial RCA connector and are meant to be used with devices equipped with an
S/PDIF output such as music servers and disc transports. note: you should use a 75Ω digital audio cable terminated with RCA
connectors to make an S/PDIF connection. “D4” uses a USB (type-B) connector and is intended for use with a computer.
Directly below the digital inputs, are two (2) pairs of analog output connectors; There is one pair of single-ended RCA analog
audio output connectors that you should connect to a stereo analog input on your preamplifier or integrated amplifier. Don’t
hesitate to use good quality interconnect cables. Immediately beside each RCA analog output is an XLR balanced outputs. We
strongly recommend that you use the balanced XLR connectors on your 300 D to maximize its level of performance:
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 the
amplifier and 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 +4 Volts, the other will be carrying a signal of –4 Volts.
When these two inverted signals on a balanced line are input into a differential preamplifier, 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 not be processed.
Your MOON 300 D is equipped with a 1/8” mini jack input for use with aftermarket infrared remote control receivers. The
“IR in” connector is located to the right of the analog audio outputs. Finally on the right side is the “AC Power” section with a
main power switch (“0”=off, “1”=on) and IEC receptacle for the included AC power cord.
All rear panel connectors have been chosen because they provide the best possible connections for your unit. 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
DAC 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.

Operating the MOON 300 D
We recommend that you leave your MOON 300 D DAC powered up at all times to maintain optimal performance. In the
event that you plan to be away from your home for a few days, switching the 300 D into “Standby” mode may not be a bad
idea. Once fully “broken-in”, please keep in mind that your 300 D will require several hours of playing time before it reaches
its 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 DAC’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
300 D 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 cables running to and from your 300 D. In the event that
this can’t be avoided, you should ensure that any cables coming into contact with each other are crossed at ninety degree
angle to minimize the contact area.
Powering up your MOON 300 D for the first time
Since this Digital-to-Analog Converter is not equipped with an on/off power switch, when connecting/disconnecting the AC
power cord you are actually turning the unit on/off. Prior to making the AC connection for the first time, make sure that every
cable is properly connected to avoid any problems. Once the 300 D is connected to an AC source it will be in “Standby
mode”. When you press the “Standby” button on the front panel, the 300 D will be ready for use and the blue LED will
illuminate.
On and Off Sequence
To avoid having any annoying noises (ie. “thumps” and “pops”) emanate from your speakers when powering your 300 D on
or off, you should
1)
Always power up your 300 D before powering up your preamplifier and/or integrated amplifier.
2)
Always power down your 300 D after powering down your preamplifier and/or integrated amplifier.
Optional remote control operation
Your MOON 300 D is equipped with an infrared input (as mentioned in the previous section) that allows for the remote
operation of certain functions. Using an aftermarket infrared remote control receiver in conjunction with the MOON CRM-2
remote control, you will be able to (i) toggle between standby mode and operational mode and (ii) switch between the four
(4) digital inputs. Please contact your authorized MOON retailer for further information.
