Simplicity, musicality, ease-of-use, and seamless hassle-free operation are some of the qualities that come to mind when describing a desireable preamplifier. Combine these attributes with incredible sonic resolution and a dead silent black background and you have the MOON P-7, a dual-mono fully balanced preamplifi- er. Cutting edge technology meets extreme build quality is perhaps the best way to sum it up. Designed for the discerning audiophile who strives to get as close to the music as possible without ever having to look back. Completing the equation is flexibility – an RS-232 port, IR input and 12 volt trigger are included to allow for seamless integration of the MOON P-7 into virtually any listening environment. Authoritative, dynamic and effortless are what one comes to expect from a world- class power amplifier. These attributes are only the tip of the iceberg when describing the MOON W-7 dual-mono power amplifier. Utilizing a balanced circuit topology, this amplifier employs the same technologies found in our flagship MOON W-8 amplifier; The proprietary Lynx circuitry is responsible for its phenomenal speed, detail and accuracy, yielding an extremely natural sound with absolutely no sonic colorations. The end result is a high current amplifier capable of driving virtually any known speaker load. delivering a very potent 150 watts per channel into 8 ohms and 300 watts into 4 ohms. Rounding out the package, the W-7 includes an RS-232 port, a 12 Volt trigger and real-time self-diagnostic monitoring circuits for both the presence of DC in the input signal and unsafe operating temperatures. Finally, you can personally customize the physical appearance of all MOON Evolution series models to best suit your needs and/or match your listening room decor with our C4aesthetics package.

P-7 Significant Design Features W-7 Significant Design Features An oversized dual-mono power supply using 3 toroidal transformers in conjnction with 5 stages of DC voltage regulation and extensive choke filtering. M-eVOL volume control circuit based on a resistive array configuration with no sonic degradation of the audio signal regardless of the selected volume setting. Power supply voltage regulation includes i2DCf (Independant Inductive DC Filtering) - 24 stages in all. Full unsolicited RS-232 bidirectional feedback, IR input for external control (all discrete codes), 12 Volt trigger for remote operations and SimLink controller port allows for 2-way communications between other MOON Evolution series components. Four-layer PCB tracings; 1 on top for ground plane, 1 on the bottom for power circuitry and 2 in middle for the audio signals. The advantages include better ground and power supply circuit layouts resulting in a much shorter signal path and dramatically improved signal-to-noise ratio. - "Gain Offset for each individual line input with a ±10dB range. - Each line input is fully configurable to be home-theater ready, where the volume of the P-7 is bypassed. - 130 individual volume steps in 1dB and 0.5dB increments. - Fully differential, no global feedback circuit topology, using absolutely no capacitors anywhere in the audio signal path. - An exceptionally short signal path measuring less than 8 inches in length from the rear panel's input to output connectors, yielding a much faster transient response. Ultra rigid chassis construction to minimize the effects of external vibrations. Pure copper circuit board tracings with extremely low impedance characteristics. - Lynx circuitry which is a "zero global 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. - 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. - Stable to any known speaker impedance.Ultra rigid chassis construction to minimize the effects of external vibrations. Technical information A great deal more energy from a power amplifier is required to reproduce musical information below 400Hz. Amplifiers with a low damping factor (and higher output impedance) have to work harder produce this energy. The majority of available power amplifiers possess a damping factor in the range of 200 (red), as shown on figure 4. Simaudio amplifiers operate with very low output impedances (typically <0.01 ohms), therefore yielding a damping factor greater than 800 in the all-important sub-400Hz range. Significantly better dynamics result in a much more powerful and authoritative bottom-end ...The immense energy of a full symphony orchestra comes to life in your own home. Ahigh dampling factor ensures an excellent grip on woofer cone motion, which reduces overshoot, and unwanted oscillations. Also greatly improves immunity to variations in quality and length of speaker cables used. The three response curves in figure 3 demonstrate (i) a theoretically perfect transformer regulation factor of 0% (green), whereby voltage remains stable regardless of the current draw, (ii) a remarkably low regulation factor of 3% (black), found in MOON W-7 amplifier, where the voltage drops very slightly as the current draw increases and (iii) a typical regulation factor of 10% (red), whereby, as the current draw increases, power supply voltage drops significantly, as found in most competing amplifier designs. Powerful musical passages are faithfully and thoroughly reproduced in an effortless manner. Apower supply transformer with a tight regulation (low) factor assures that power into more difficult speaker loads will be delivered closer to the theoretical ideal. These transformes are significantly more expensive, but are the only way to assure stability and consequently excellent sound quality under all conditions. An oversized power supply. Precision matched and fully decoupled Bipolar output devices which offer superb linearity throughout the entire audio frequency spectrum (12 per channel). Full unsolicited RS-232 bidirectional feedback, IR input for external control (all discrete codes) and 12 Volt trigger for remote operations . 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.
