MOON CLASSIC SERIES
Aurora High-Current Power Amplifier


 
 



Available in configurations of 5 and 7 channels, this state-of-the-art multi-channel power amplifier represents a less expensive alternative to the Titan and is the perfect mate for a high-performance surround processor such as our MOON Stargate. Using technologies found in our other MOON series power amplifiers, the Aurora is capable of producing a high-current output signal to a maximum continuous power rating of 200 watts per channel into 8 ohms and 400 watts per channel into 4 ohms.

 



  Significant Design 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 · An oversized power supply · Class A output to 5 watts for greater efficiency · Fully balanced circuitry up to the output stage · Extremely fast circuitry yielding real-time amplification · "Rack mount ready" faceplate with removeable aluminum cheeks to cover the rack holes when not in use · Thermally interconnected chassis design which enhances sonic harmony by maintaining identical operating temperatures for all channels · Virtually non-existent inter-modulation distortion · Precision matched 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 · Accurate matching of the highest quality electronic components · 12 Volt trigger for remote operation · Very short signal path for a faster transient response · 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.
