Designed for uncompromising reference-level systems, the M400 MXV delivers exceptional authority, transparency, and dynamic precision from an elegantly compact monoblock chassis.\n\u003c\/p\u003e\n\n\u003cp\u003e\nCentral to the design is a newly engineered 2,200VA ultra-quiet linear transformer paired with a nearly 100,000μF capacitor bank, providing dramatically increased current capability and improved transient response. Redesigned driver and output stages utilize high-speed 69MHz transistors and fully complementary balanced circuitry to expand bandwidth, reduce distortion, and enhance overall musical realism across the frequency spectrum.\n\u003c\/p\u003e\n\n\u003cp\u003e\nThe Momentum M400 MXV also incorporates Dan D'Agostino’s distinctive copper venturi-style heatsink system for exceptional thermal efficiency and increased Class A operation. Finished with the company’s signature Swiss watch-inspired analog power meter and precision-machined aluminum\/copper chassis construction, the M400 MXV delivers state-of-the-art monaural amplification with unmistakable industrial design.\n\u003c\/p\u003e\n\n\u003cp\u003e\n\u003cstrong\u003eAvailable in Silver or Black finishes\u003c\/strong\u003e\n\u003c\/p\u003e\n\n\u003ch3 style=\"color:#f39c12; font-size:14px; margin-bottom:6px;\"\u003e\n\u003cstrong\u003eFEATURES\u003c\/strong\u003e\n\u003c\/h3\u003e\n\n\u003cul style=\"margin-top:0;\"\u003e\n\u003cli\u003eFully balanced monaural power amplifier design\u003c\/li\u003e\n\u003cli\u003eMXV-generation Momentum circuitry\u003c\/li\u003e\n\u003cli\u003e400W continuous output into 8 ohms\u003c\/li\u003e\n\u003cli\u003e800W continuous output into 4 ohms\u003c\/li\u003e\n\u003cli\u003e1600W continuous output into 2 ohms\u003c\/li\u003e\n\u003cli\u003e2,200VA ultra-quiet linear transformer\u003c\/li\u003e\n\u003cli\u003eNearly 100,000μF capacitor bank\u003c\/li\u003e\n\u003cli\u003eFully complementary direct-coupled circuitry\u003c\/li\u003e\n\u003cli\u003e69MHz high-speed output transistors\u003c\/li\u003e\n\u003cli\u003e26 matched output transistors\u003c\/li\u003e\n\u003cli\u003eEnhanced Class A operating range\u003c\/li\u003e\n\u003cli\u003eCopper venturi-style heatsink system\u003c\/li\u003e\n\u003cli\u003eSingle balanced XLR input\u003c\/li\u003e\n\u003cli\u003eCustom speaker binding posts\u003c\/li\u003e\n\u003cli\u003eSwiss watch-inspired analog power meter\u003c\/li\u003e\n\u003cli\u003ePrecision-machined aluminum and copper chassis construction\u003c\/li\u003e\n\u003cli\u003eUpgradeable from previous Momentum monoblock amplifiers\u003c\/li\u003e\n\u003cli\u003eHand-built and individually tested in the USA\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3 style=\"color:#f39c12; font-size:14px; margin-bottom:6px;\"\u003e\n\u003cstrong\u003eSPECIFICATIONS\u003c\/strong\u003e\n\u003c\/h3\u003e\n\n\u003cp\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Monaural Power Amplifier\u003cbr\u003e\n\u003cstrong\u003eAmplifier Class:\u003c\/strong\u003e Class AB\u003cbr\u003e\n\u003cstrong\u003eOutput Power:\u003c\/strong\u003e 400W @ 8Ω \/ 800W @ 4Ω \/ 1600W @ 2Ω\u003cbr\u003e\n\u003cstrong\u003eFrequency Response:\u003c\/strong\u003e 1Hz – 200kHz (-1dB) \/ 20Hz – 20kHz ±0.1dB\u003cbr\u003e\n\u003cstrong\u003eSignal-to-Noise Ratio:\u003c\/strong\u003e \u0026gt;85dB A-weighted \/ \u0026gt;115dB unweighted\u003cbr\u003e\n\u003cstrong\u003eGain:\u003c\/strong\u003e 27dB\u003cbr\u003e\n\u003cstrong\u003eTotal Harmonic Distortion:\u003c\/strong\u003e 0.09% @ 1kHz, 400W @ 8Ω\u003cbr\u003e\n\u003cstrong\u003eInput Impedance:\u003c\/strong\u003e 100kΩ\u003cbr\u003e\n\u003cstrong\u003eOutput Voltage:\u003c\/strong\u003e 150V peak-to-peak \/ 75V RMS\u003cbr\u003e\n\u003cstrong\u003eOutput Current:\u003c\/strong\u003e 40A peak\u003cbr\u003e\n\u003cstrong\u003eOutput Impedance:\u003c\/strong\u003e \u0026lt;0.11Ω, 20Hz – 20kHz\u003cbr\u003e\n\u003cstrong\u003ePower Consumption:\u003c\/strong\u003e Standby 3.8W \/ Idle 105W \/ Maximum 2700W\u003cbr\u003e\n\u003cstrong\u003eInputs:\u003c\/strong\u003e 1 x Balanced XLR\u003cbr\u003e\n\u003cstrong\u003eOutputs:\u003c\/strong\u003e 1 Pair Speaker Binding Posts\u003cbr\u003e\n\u003cstrong\u003eDimensions (W × H × D):\u003c\/strong\u003e 12.5 × 5.25 × 21.5 in.
