Its fully balanced differential topology and oversized toroidal-based power supply deliver fast transients, punchy low-end impact, and a wide-open top end that stays smooth even at higher listening levels. With Class A output to 10 watts and a refined A\/AB operating mode, the 400M blends delicacy at low volume with commanding headroom when the music swells. For modern systems and custom installs, it also includes 12V trigger in\/out and an RS-232 port for integration and control.\u003cspan\u003e \u003c\/span\u003e\u003c\/p\u003e \u003cp\u003e\u003cimg src=\"https:\/\/storage.googleapis.com\/lupublic\/MOONCertifiedReserve_OK1.png\" alt=\"MOON 780D v2 Network Player\/DAC Certified Reserved\"\u003e\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eThe MOON Certified Reserve Standard\u003c\/strong\u003e\u003c\/p\u003e \u003cp style=\"text-align: left;\"\u003e\u003cspan\u003eEvery MOON Certified product meets a strict manufacturer standard:\u003c\/span\u003e\u003c\/p\u003e \u003cul\u003e \u003cli aria-level=\"1\" style=\"text-align: left;\"\u003e\u003cspan\u003eFully tested, refurbished, and certified by MOON technicians\u003c\/span\u003e\u003c\/li\u003e \u003cli aria-level=\"1\" style=\"text-align: left;\"\u003e\u003cspan\u003eIncludes new packaging and complete accessory packs\u003c\/span\u003e\u003c\/li\u003e \u003cli aria-level=\"1\" style=\"text-align: left;\"\u003e\u003cspan\u003eTechnician sign-off certification included\u003c\/span\u003e\u003c\/li\u003e \u003cli aria-level=\"1\" style=\"text-align: left;\"\u003e\u003cspan\u003eBacked by a 5-year manufacturer warranty\u003c\/span\u003e\u003c\/li\u003e \u003c\/ul\u003e \u003ch4 role=\"heading\" aria-level=\"3\" data-uw-rm-heading=\"level\"\u003e\u003ca href=\"https:\/\/listenup.com\/pages\/moon-certified-reserve\" data-uw-rm-brl=\"PR\" data-uw-original-href=\"https:\/\/listenup.com\/pages\/moon-certified-reserve\"\u003eSee Available MOON Certified Reserve\u003c\/a\u003e\u003c\/h4\u003e \u003ch4 data-uw-rm-heading=\"prs\"\u003e\u003ca href=\"https:\/\/listenup.com\/pages\/moon\" data-uw-rm-brl=\"PR\" data-uw-original-href=\"https:\/\/listenup.com\/pages\/moon\"\u003eSee All MOON\u003c\/a\u003e\u003c\/h4\u003e \u003ch4\u003eMOON 400M Full Specifications:\u003c\/h4\u003e \u003cul\u003e \u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eMono (monoblock) power amplifier\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eCircuit \/ Configuration:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eFully Balanced Differential, Mono\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eClass of operation:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eA\/AB\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eClass A output:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eUp to 10 watts\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eOutput power @ 8Ω:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e400 W\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eOutput power @ 4Ω:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e650 W\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eGain:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e36 dB\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eFrequency response (full range):\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e10 Hz – 125 kHz (+0 \/ −3 dB)\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eSignal-to-noise ratio:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e106 dB @ full power\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eInput sensitivity:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e800 mV RMS\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eInput impedance:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e47,500 Ω\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eIntermodulation distortion:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e0.02%\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eTHD (20 Hz – 20 kHz @ 1 W):\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e0.02%\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eTHD (20 Hz – 20 kHz @ 400 W):\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e0.05%\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003ePower supply transformer:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e400 VA\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003ePower supply capacitance:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e85,000 µF\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eOutput device type:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eMOON Bipolars (precision matched proprietary MOON bipolar output transistors)\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003ePower consumption @ idle:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e36 W\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eAC power requirements:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e120V \/ 60Hz or 240V \/ 50Hz\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eFuse replacement:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e120V version uses 8A fast blow (3AG);
