The MOON Nēo 400M is a differential mono power amplifier that produces 400 watts into 8Ω and 650 Watts into 4Ω. Based on our highly acclaimed Advanced Renaissance amplifier circuitry, the class A/AB, zero global feedback, DC-coupled Nēo 400M is capable of producing tight, deep and powerful bass with lightning fast speed; True high-performance in a compact package without compromise. Possessing a high damping factor, an incredibly low noise floor, excellent dynamic range and a transparent lifelike soundstage, the MOON Nēo 400M will effortlessly drive any loudspeaker. Even difficult loads will not impede its ability to remain exceedingly musical and accurate. Our own unique heat-sink geometry allows for ultra-effective and efficient cooling. The amplifier’s oversized power supply contains a large proprietary toroidal transformer and substantial energy storage. Finally, with both balanced (XLR) and single-ended (RCA) inputs, the MOON Nēo 400M represents the ultimate choice for performance and affordability. All Nēo products are available in all black finish as standard or in 2-tone black and silver or all silver as a special order. Specs A “no overall feedback” design resulting in genuine 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 An oversized power supply 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 Precision matched proprietary MOON Bipolar output transistors with unprecedented gain linearity, resulting in improved bass response and even more accurate sonic reproduction A high damping factor for superior musical dynamics, improved signal speed and refined timbre accuracy Fully balanced differential circuitry “Class A” output to 10 watts for greater efficiency 12 Volt trigger input/output for remote operations RS-232 port for (i) full unsolicited bidirectional feedback and (ii) firmware updates Rigid chassis construction to minimize the effects of external vibrations Optimized selection of very high quality electronic components Low operating temperature for an ultra-long life expectancy.
