Dedicated McIntosh Autoformers on each channel allow the amplifier to provide its full rated output regardless of which supported impedance is connected, making the MC462 suitable for a wide range of demanding loudspeakers.\u003c\/p\u003e\n\u003cp\u003eCompared with the preceding MC452, the MC462 increases filter capacity by nearly 50%, raising dynamic headroom from 1.8 dB to 3 dB. The additional energy storage helps the amplifier accommodate large musical peaks while also contributing to improved low-frequency performance.\u003c\/p\u003e\n\u003cp\u003eThe MC462 uses McIntosh’s Quad Balanced circuit architecture to reduce noise and distortion within the amplification stages. Four Monogrammed Heatsinks are coupled to the high-current output transistors for efficient thermal management, while Power Guard monitors the signal to prevent clipping and Sentry Monitor protects the output stage against unsafe operating conditions.\u003c\/p\u003e\n\u003cp\u003eBalanced and unbalanced outputs provide additional system flexibility, allowing the signal to be passed to another amplifier for bi-amping or tri-amping, sent to a secondary system, or routed to a powered subwoofer. The amplifier is built on a polished stainless-steel chassis and retains McIntosh’s black glass front panel, aluminum handles, illuminated logo, and pair of fast-responding blue watt meters.\u003c\/p\u003e\n\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\n\u003ch4\u003e450 Wpc Into 2, 4, or 8 Ohms\u003c\/h4\u003e\n\u003cp\u003eDedicated McIntosh Autoformers allow each channel to deliver the full rated 450 W into 2-, 4-, or 8-ohm loudspeaker loads, providing consistent rated output across a broad range of speaker impedances.\u003c\/p\u003e\n\n\u003ch4\u003e3 dB Dynamic Headroom\u003c\/h4\u003e\n\u003cp\u003eIncreased filter capacity gives the MC462 3 dB of dynamic headroom, providing additional short-term power for musical peaks and improving the amplifier’s ability to reproduce large changes in level without clipping.\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 high-power operation.\u003c\/p\u003e\n\n\u003ch4\u003ePower Guard\u003c\/h4\u003e\n\u003cp\u003ePower Guard continuously compares the amplifier’s input and output signals and adjusts the input when necessary to prevent clipping that could otherwise produce harsh distortion or damage loudspeakers.\u003c\/p\u003e\n\n\u003ch4\u003eSentry Monitor\u003c\/h4\u003e\n\u003cp\u003eSentry Monitor provides fuse-less short-circuit 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\u003eMonogrammed Heatsinks\u003c\/h4\u003e\n\u003cp\u003eFour McIntosh Monogrammed Heatsinks are connected to the high-current output transistors to provide efficient thermal management and help reduce thermal equilibrium lag.\u003c\/p\u003e\n\n\u003ch4\u003eFlexible System Connections\u003c\/h4\u003e\n\u003cp\u003eBalanced and unbalanced outputs make it easier to add another amplifier for bi-amping or tri-amping, feed a second audio system, or connect a powered subwoofer when additional preamplifier outputs are not available.\u003c\/p\u003e\n\n\u003ch4\u003eSolid Cinch Speaker Binding Posts\u003c\/h4\u003e\n\u003cp\u003eMcIntosh Solid Cinch binding posts provide secure speaker-cable connections and are gold-plated to resist corrosion.\u003c\/p\u003e\n\n\u003ch4\u003ePower Control\u003c\/h4\u003e\n\u003cp\u003eMcIntosh Power Control allows compatible components to receive coordinated power-on and power-off commands as part of a complete McIntosh system.\u003c\/p\u003e\n\n\u003ch3\u003eWhat’s Included\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eMcIntosh MC462 Stereo Power Amplifier\u003c\/li\u003e\n\u003cli\u003eRemote control\u003c\/li\u003e\n\u003cli\u003eAC power cord\u003c\/li\u003e\n\u003cli\u003eOwner’s manual\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cp\u003e\u003cb\u003eType:\u003c\/b\u003e Solid-state stereo power amplifier\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eChannels:\u003c\/b\u003e 2\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003ePower Output:\u003c\/b\u003e 450 Wpc 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;
