MOON 860A Dual-Mono Power Amplifier
Introduction
Your MOON 860A Dual-Mono Power Amplifier incorporates many significant design features to achieve its “world-class” level
of performance. This is an abbreviated list of the more important features:
Proprietary “Lynx” Technology which eliminates feedback. The results are: Real-time amplification is achieved since
interactions from the speaker back to the amplifier are virtually eliminated; More accurate musical reproduction with
respect to tonality; Virtually non-existent transient intermodulation distortion (which is far more degrading to sonic
performance than harmonic distortion); The elimination of common phase errors resulting from feedback.
A custom proprietary toroidal transformer design with lower magnetic, electrical and thermal loss, yielding an
improved power transfer and lower regulation factor, resulting in increased current speed and better dynamics.
Fully balanced differential circuitry up to the output stage.
Output stable to any known speaker impedance.
Class A output to 5 watts for greater efficiency.
An oversized power supply.
An exceptionally short signal path for a faster transient response.
Precision matched and fully decoupled proprietary MOON Bipolar Output transistors with unprecedented gain
linearity resulting in improved bass response and even more accurate sonic reproduction.
A high damping factor which yields superior musical dynamics, improved signal speed and refined timbre accuracy.
Extremely rigid chassis construction to minimize the effects of external vibrations.
Accurate matching of the very finest high quality electronic components.
Pure copper circuit board tracings with extremely low impedance characteristics.
Designed to be powered up at all times for optimal performance.
Installation & Placement
The MOON 860A 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 860A 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.
In the event that the surface you have chosen isn’t perfectly level, each of the four (4) cones of your 860A 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.
