MOON P-7 Dual-Mono Preamplifier

Introduction

Your MOON P-7dual-mono preamplifier incorporates many significant design features to achieve its “world-class” level of performance. This is an abbreviated list of the more important features:

Full unsolicited RS-232 bidirectional feedback

An oversized dual-mono power supply using 3 toroidal transformers in conjunction with 5 stages of DC voltage regulation and extensive choke filtering

SimLink controller port allows for 2-way communications between other compatible MOON Evolution Series components

M-eVOLvolume control circuit based on a resistive array configuration, resulting in no sonic degradation of the audio signal regardless of the selected volume setting

M-Lockcircuit for “user selectable” maximum volume setting lock-out for each line input

Power supply voltage regulation includes i2DCf (Independent Inductive DC Filtering); 1 inductor for each and every IC in the audio circuit’s signal path – 24 stages in all

Gain offset for each individual line input with a ±10dB range

Each line input is fully configurable to be “home theater ready”, where the volume control of the P-7 is bypassed

130 individual volume steps in 1dB and 0.5dB increments

Four-layer PCB tracings; The advantages include better ground and power supply circuit layouts resulting in a much shorter signal path and dramatically improved signal-to-noise ratio

Extremely rigid chassis construction to minimize the effects of external vibrations

Accurate matching of the very finest quality electronic components in a symmetrical circuit design

Improved reliabilty through the elimination of moving parts.

Installation & Placement

The MOON P-7dual-mono preamplifier is very heavy. It requires reasonable ventilation to maintain an optimum and consistent operating temperature. Consequently, 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 the preamplifier’s performance and reliability.

Once you’ve decided on a location for the P-7 Preamplifier, you should install the eight (4) pointed screw-on cones into the threaded holes located on the bottom of the four (4) the corner posts of both the Preamplifier chassis. These cones will easily scratch most surfaces, therefore it’s advisable to follow these instructions: Place your P-7on a soft surface (i.e. carpet) and carefully turn it so that it rests on its side. Screw one cone onto each of the four posts. Carefully move the chassis to it’s pre- determined location.

In the event that the surface you have chosen isn’t perfectly level, each of the four (4) legs of both your P-7are 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.
