Installation & Placement

The MOON 870A Dual-Mono power amplifier is both powerful and heavy. It requires reasonable ventilation 
to maintain an optimum and consistent operating temperature, especially since it will radiate heat when 
driven hard. Consequently, it should be placed in a location with empty space around it for proper heat 
dissipation. You should never place another component on top of this amplifier. As well, the amplifier 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 amplifier’s performance and reliability. The 870A uses 
two large toroidal transformers in its power supply; even though they are well shielded, you should not place 
this amplifier too close to source components sensitive to EMI, such as turntables, phono preamplifiers and 
CD Players.

If the surface you have chosen isn’t perfectly level, each of the four (4) cones of your 870A 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.
