MOON P-5 Dual-Mono Preamplifier

Introduction

Your MOON P-5 Dual-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:

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 throughout the entire preamplifier.

An oversized power supply housed in a separate matching chassis.

Eight stages of DC voltage regulation.

An exceptionally short, capacitor-free signal path measuring only nine inches in length for a faster

transient response.

Open-loop zero feedback circuit topology.

Proprietary designed “RGB” fully discrete “shunt to ground” gain stage employing a precision relay

network which uses only one metal film resistor at any given time (rather than a series of resistors), for the

audio signal to pass through, resulting in a gain control that doesn't degrade sonic performance regardless

of the selected setting.

J-FET input devices and MOSFET output devices.

One single-ended audio input which functions as a “pass-through”, which bypasses the gain stage to

accommodate a component such as a home-theater processor, whose own volume control is used instead.

Extremely rigid chassis construction to minimize the effects of external vibrations.

Accurate matching of the very finest high quality electronic components.

A symmetrical circuit design.

Pure copper circuit board tracings with extremely low impedance characteristics.

Designed to be powered up at all times for optimal performance.

Low operating temperature for a longer than normal life expectancy.
