Designed for demanding loudspeakers, large listening spaces, and reference-level stereo or home theater systems, it combines enormous power reserves with McIntosh’s Quad Balanced circuitry and Autoformer-coupled output stage.\u003c\/p\u003e\n\u003cp\u003eMcIntosh’s Autoformer allows the MC2.1KW to deliver its full rated 2,000 W into 2-, 4-, or 8-ohm loudspeaker loads. Dedicated output terminals are provided for each impedance, and each set includes three pairs of Solid Cinch speaker binding posts, making bi-wiring and tri-wiring straightforward without stacking multiple cables onto a single terminal.\u003c\/p\u003e\n\u003cp\u003eCompared with the preceding MC2KW, the MC2.1KW uses substantially larger filter capacitors to increase dynamic headroom and improve low-frequency performance. Eight large capacitors are distributed between the two Power Modules, while updated circuitry, shorter signal paths, revised internal wiring, and modern components further refine the design.\u003c\/p\u003e\n\u003cp\u003eThe two Power Modules connect to the Output Module using locking IP68-rated interconnect cables. Each Power Module also carries four McIntosh Monogrammed Heatsinks coupled to the high-current output transistors for efficient thermal management. Despite the amplifier’s exceptional output capability, operation remains entirely solid state and convection cooled.\u003c\/p\u003e\n\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003ch4\u003e2,000 W Into 2, 4, or 8 Ohms\u003c\/h4\u003e\n\u003cp\u003eMcIntosh Autoformer output transformers allow the amplifier to deliver its full rated power into 2-, 4-, or 8-ohm loudspeakers instead of reserving maximum output for a single nominal impedance.\u003c\/p\u003e\n\n\u003ch4\u003eThree-Chassis Architecture\u003c\/h4\u003e\n\u003cp\u003eThe MC2.1KW separates its amplification and output circuitry across two Power Modules and one Output Module. This distributes the amplifier’s substantial power supply and output hardware while allowing each section to be optimized for its specific task.\u003c\/p\u003e\n\n\u003ch4\u003eQuad Balanced Circuitry\u003c\/h4\u003e\n\u003cp\u003eMcIntosh’s Quad Balanced topology uses complementary amplifier sections to cancel noise and distortion components within the signal path while providing the current capability required for the MC2.1KW’s high output.\u003c\/p\u003e\n\n\u003ch4\u003eIncreased Power-Supply Capacity\u003c\/h4\u003e\n\u003cp\u003eEight large filter capacitors housed in the Power Modules provide increased energy storage compared with the previous MC2KW, contributing to a rated 2.1 dB of dynamic headroom and improved low-frequency performance.\u003c\/p\u003e\n\n\u003ch4\u003ePower Guard\u003c\/h4\u003e\n\u003cp\u003eMcIntosh Power Guard monitors the amplifier’s input and output signals and dynamically adjusts the input level when necessary to prevent clipping that could otherwise produce harsh distortion or damage loudspeaker drivers.\u003c\/p\u003e\n\n\u003ch4\u003eSentry Monitor\u003c\/h4\u003e\n\u003cp\u003eSentry Monitor provides fuse-less protection for the output stage, disengaging it if current exceeds safe operating limits and automatically restoring operation when conditions return to normal.\u003c\/p\u003e\n\n\u003ch4\u003eFlexible Speaker Connections\u003c\/h4\u003e\n\u003cp\u003eSeparate 2-, 4-, and 8-ohm output platforms each provide three sets of McIntosh Solid Cinch speaker binding posts, supporting conventional connection as well as bi-wired or tri-wired loudspeakers.\u003c\/p\u003e\n\n\u003ch4\u003eDual Input Sets\u003c\/h4\u003e\n\u003cp\u003eTwo balanced and two unbalanced inputs provide additional system flexibility, including installations where the amplifier may be used with more than one source or control configuration.\u003c\/p\u003e\n\n\u003ch3\u003eWhat’s Included\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e1 × MC2.1KW Output Module\u003c\/li\u003e\n\u003cli\u003e2 × MC2.1KW Power Modules\u003c\/li\u003e\n\u003cli\u003eModule interconnect cables\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cp\u003e\u003cb\u003eType:\u003c\/b\u003e Solid-state monoblock power amplifier\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eChannels:\u003c\/b\u003e 1\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003ePower Output:\u003c\/b\u003e 2,000 W into 2, 4, or 8 ohms\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eRated Power Band:\u003c\/b\u003e 20 Hz–20 kHz\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eFrequency Response:\u003c\/b\u003e 20 Hz–20 kHz, +0\/–0.25 dB;
