The MOON W-8 RS Power Amplifier is a dual-mono balanced differential design, representing the next generation of MOON high-performance audio components. Producing 250 watts per channel of uncolored high-current output power at 8Ω (500 wpc into 4Ω and 1000wpc into 2Ω), the W-8 RS 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-8 RS 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:
· Lynx circuitry which is a "no overall feedback" design resulting in genuine real-time amplification,
a more accurate musical reproduction with respect to tonality, virtually non-existent IMD 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
· An oversized power supply
· 12 Volt trigger input/output for remote operation
· "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
refined timbre accuracy
· A very short capacitor-free signal path for a faster transient response
· 4-Layer PCB’s with pure copper tracings for a much shorter signal path; This results in
greater sonic accuracy and a dramatically improved signal-to-noise ratio
· 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.
New technologies include (i) the M-eVOL2 volume control, with a phenomenal 530 steps, allowing for an extremely precise level adjustment just like the MOON P-8 Preamplifier; (ii) New MOON output transistors, specifically designed for use in our amplifiers, provide tighter and more visceral bass performance, as well as unprecedented linearity thoughout the entire frequency spectrum; (iii) An input stage circuit which reduces noise, preserving image focus and integrity like never before.
that must be heard to be believed.
Of course, key features you’d expect in a MOON Evolution Series products are present such as our revolutionary Lynx amplification circuitry, SimLink and M-Lock, just to name a few, as well as both RS-232 and IR ports for custom-install environments. Finally, a plethora of user selectable cosmetic options are available at the time of purchase.
