MOON CLASSIC SERIES
ROCK Mono Differential Power Amplifier
|
 
|
|  
|
The MOON ROCK is a fully balanced differential mono-block amplifier that produces an
ultra-high-currentoutput signal to a maximum continuous rating of 1000 watts into 8 ohms
and 2000 watts into 4 ohms, easily capable of driving virtually any loudspeaker.
Using 32 bipolar output devices in conjunction with internal electronic component
matching to exceptionally low tolerances, the ROCK pushes the boundaries of
solid-state amplifier design. With a very strong emphasis on form and finish, this
amplifier includes a customized 2 inch thick solid granite base, weighing in at
over 120 lbs., as well as an anodized top cover.

Significant Design Features
A custom proprietary toroidal transformer design with lower magnetic, electrical and thermal loss,
yielding an imrpoved power transfer and lower regulation factor, resulting in increased current
speed and better dynamics ·
An oversized power supply ·
Fully balanced circuitry throughout the entire amplifier ·
Stable to any known speaker impedance ·
Class A output to 20 watts for greater efficiency ·
Virtually non-existent inter-modulation distortion ·
Extremely fast circuitry yielding real-time amplification ·
Mechanical grounding accomplished through the use of a solid granite base ·
Precision matched and fully decoupled Bipolar output devices which offer superb linearity throughout the entire audio
frequency spectrum ·
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 ·
A very short signal path for a faster transient response ·
Accurate matching of the highest quality electronic components to tolerances as low as 0.01% ·
A symmetrical circuit design ·
Pure copper circuit board tracings with extremely low impedance characteristics ·
A 12 Volt trigger for remote operations ·
Two pairs of high quality binding posts to facilitate bi-wiring ·
Designed to be powered up at all times for optimal performance ·
