MOON EVOLUTION SERIES                           Updated: December 19, 2006
W-7 Dual-mono Power Amplifier
 



The MOON W-7 Power Amplifier is a dual-mono balanced differential design, representing the next generation of MOON high-performance audio components. Producing 150 watts per channel of uncolored high-current output power into 8 ohms (300 wpc into 4 ohms & 500wpc into 2 ohms), the W-7 will drive virtually any loudspeaker to its maximum capabilities with incredible ease. This achievement is due, in part, to our new proprietary "Lynx" amplification circuit. Further raising the bar, the MOON W-7 can be fully integrated into a custom-install environment via an RS-232 port and 12V trigger. As well, a plethora of user selectable cosmetic options are available at the time of purchase.

Significant Design Features

An oversized power supply · Full unsolicited RS-232 bidirectional feedback · Lynx circuitry which is a "no overall feedback" design resulting in real-time amplification, a more accurate musical reproduction with respect to tonality, virtually non-existent intermodulation distortion and the elimination of common phase errors resulting from feedback · Custom proprietary toroidal transformer design with lower magnetic, electrical and thermal loss, yielding an improved power transfer and lower regulation factor. The result is increased current speed and better dynamics · 12 Volt trigger for remote operations · "Class A" output to 5 watts for greater efficiency · Precision matched and fully decoupled Bipolar output devices which offer superb linearity throughout the entire audio frequency spectrum · A high damping factor yielding superior musical dynamics, improved signal speed and refined timbre accuracy · A very short capacitor-free signal path for a faster transient response · Pure copper circuit board tracings with extremely low impedance characteristics · Stable to any known speaker impedance · Ultra rigid chassis construction to minimize the effects of external vibrations · Accurate matching of the very finest quality electronic components in a symmetrical circuit design · Designed to be powered up at all times for optimal performance.

Overseas MOON W-7 RS

The RS series of MOON audio components benefit from an even higher standard of manufacturing process than the regular MOON versions. All significant differences are contained within the circuitry and construction of each model.

RS versions are built using different materials and parts in certain areas. For example, printed circuit boards are of a higher temperature grade than that of the military specification FR-4 material we normally use; Their traces are gold-plated instead of a tin/lead composite. As well, all capacitors use improved dielectric materials.

MOON RS models meet and/or exceed stricter manufacturing processes as required to pass many international safety standards such as those imposed by the E-U, Japan and South Korea. Cosmetically, the ONLY difference is the RS logo on the front panel.
