MOON 310LP Phono Preamplifier

 

 

Introduction 

 

Your MOON 310LP Phono Preamplifier incorporates many significant design features to achieve its “world class” level of 
performance.  This is an abbreviated list of the more important features:    

 

Isolated power supply on a separate circuit board using a toroidal transformer with 2 stages of voltage regulation. 

 

An extremely short signal path for a faster transient response.    

 

End-user adjustments for capacitance loading, resistance loading and gain level to extract exceptional performance 
from virtually all high quality phono cartridges. 

 

End-user adjustments to alternate between the RIAA and IEC equalization curves. 

 

Single-ended RCA and Balanced XLR output connectors. 

 

Optional external power supply

 

Power supply voltage regulation includes i

2

DCf (Independent Inductive DC Filtering) derived from the Evolution Series for 

increased dynamic range. 

 

Four-layer PCB tracings with dedicated ground and power planes using pure copper for low impedance characteristics. 
The advantages are better circuit layouts resulting in much shorter signal paths and a vastly improved signal-to-noise ratio. 

 

Rigid chassis construction to minimize the effects of external vibrations.     

 

symmetrical circuit design with accurate matching of the very finest high quality electronic components.  

 

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 310LP 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. 

You should never place another component directly on top of 

this phono preamplifier. 

 
The 310LP is more sensitive than most other types of audio components to EMI (electro-magnetic interference) from power 
supplies and motors. Consequently, it should be placed at a minimum distance of 18 inches from power supplies, turntables, 
tape decks, AC line filters, etc.

 

 
 

IMPORTANT:   A turntable with a functional cartridge MUST be connected to the MOON 310LP Phono 

Preamplifier prior to connecting the AC power cord, otherwise you may damage your 
amplifier and/or loudspeakers.
