Figure 11:  MOON 310LP Rear panel 

 

The rear panel will look similar to Figure 11 (above).  There is one pair of single-ended inputs on RCA connectors located in 
the center with a ground post directly below. Connect the cables from your turntable to these inputs and the ground lead wire 
to the ground post. The MOON 310LP Phono Preamplifier has two pairs of outputs; One single-ended pair on RCA 
connectors and one balanced pair on XLR connectors.  
 
In the event that the preamplifier/integrated amplifier you’re connecting the 310LP to has balanced inputs, its highly 
advantageous to use the 310LP’s XLR outputs. This will provide you with an even better signal-to-noise ratio and increased 
gain by a factor of 6dB.   
 
Don’t hesitate to use high quality interconnects. Poor quality cables can degrade the overall sonic performance of your 
system. 

 

Finally on the right side the IEC receptacle, labeled “AC Power” for the included AC power cord. Directly above the IEC 
receptacle is a 4-pin XLR connector labeled “DC Power”; this is for the optional 310LP external power supply upgrade. 

 

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 
Phono Preamplifier 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 can degrade the performance of your components over the long term.
