Installation & Placement 
The  MOON 850P dual-mono preamplifier is very 
heavy and 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 the preamplifier’s 
performance and reliability. 
If the surface you have chosen isn’t perfectly level, 
each of the four (4) legs of both your 850P and it’s 
power supply / controller are height adjustable; 
carefully using your fingers, you can either raise 
each leg by turning the cone underneath clockwise, 
or lower each leg by turning it counterclockwise. 
We strongly recommend that you leave these cones 
mounted to the component at all times for reasons 
related to both performance and aesthetics.
