MOON i 3.3 Integrated Amplifier 
Introduction 
Your MOON i 3.3  integrated amplifier incorporates many significant design features to achieve its “world class” level of 
performance. This is an abbreviated list of the more important features: 
An oversized power supply using a custom toroidal transformer design 
Rated output of 100 watts/channel into 8 ohms and 200 watts/channel into 4 ohms 
Five line-level inputs including one front-mounted 1/8” mini-jack for personal media players 
One single-ended audio input which functions as a “pass-through”, bypassing the gain stage to accommodate a 
component such as a home-theater processor, whose own volume control is used instead.
Optional
 internal digital-to-analog converter circuit for use with a PC, digital music server or external transport, etc 
Optional
 internal phono preamp is available with adjustments for gain level as well as capacitance and resistance loading 
Optional
 line-level balanced XLR input 
Headphone output on ¼” TRS jack located on the front panel 
Remote control operation 
RS-232 port for i) full unsolicited bidirectional feedback in custom installation setups and ii) firmware updates 
IR input for external control 
SimLink
TM
 controller port allows for 2-way communications between other compatible MOON components 
Four bipolar output devices per channel in the amplification section which offer superb linearity throughout the entire 
audio frequency spectrum 
Class “A” output to 5 watts for greater efficiency 
Circuit board with pure copper tracings and gold plating that yields low impedance characteristics 
Optimized selection of very high quality electronic components 
Rigid chassis construction to minimize the effects of external vibrations 
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 i
 3.3 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 or inside a closed cabinet that is not well ventilated as this could 
compromise this component’s performance and reliability. The i
  3.3 uses a toroidal transformer; even though it is well 
shielded, you should not place the integrated amplifier 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 integrated amplifier.
