The MC462 replaces the highly regarded MC452 as our most powerful stereo amplifier. Like the MC452, it features a robust output of 450 Watts per channel. With a dedicated McIntosh Autoformer™ connected to each audio channel, the full 450 Watts is available to any speaker regardless if it has 2, 4 or 8 Ohm impedance. Just one MC462 Amplifier can single-handedly power a world class home audio stereo system.\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003eThe new generation MC462 stereo amplifier has received numerous updates compared to the previous model. The most prominent is that filter capacity has been increased by nearly 50%, which has resulted in a remarkable 66% increase in dynamic headroom from 1.8dB to 3.0dB. This allows the MC462 to easily handle drastic swings in dynamics and effortlessly reproduce your favorite music with virtually no distortion. Bass performance is also improved as a result of the filter capacity increase. Our eco-friendly power management system, which will turn the amplifier off after a set amount of time when no input signal has been detected, has been added. Internal wiring and select circuit components have also been upgraded.\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003eAesthetically, the MC462 retains all the hallmarks of a McIntosh amplifier with a few key modern enhancements. The front panel now utilizes direct LED backlighting that improves appearance and color accuracy. The two audio Autoformers and single power transformer are housed in new enclosures topped by a single machined cover with glass inserts. The back half of the amplifier is home to four of our Monogrammed Heatsinks™ which connect to advanced high current output transistors that help eliminate thermal equilibrium lag time.\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003eBesides these updates, the MC462 is packed full of other exclusive McIntosh technologies to bring your music to life:\u003cbr\u003e• Power Guard® that monitors and adjusts the input signal at the speed of light and makes real time adjustments to prevent harsh sounding and potentially speaker damaging clipping\u003cbr\u003e• Sentry Monitor™ - our fuse-less short-circuit protection circuit that disengages the output stage before current exceeds safe operating levels and then resets automatically when operating conditions return to normal\u003cbr\u003e• Quad Balanced design that cancels virtually all noise and distortion that may have crept into the audio signal\u003cbr\u003e• Power Control to send power on\/off signals to other connected McIntosh components (such as CD Players, turntables, tuners and media streamers) for easy system power up and shutdown\u003c\/p\u003e\n\u003cp\u003e• Our patented Solid Cinch™ speaker binding posts that easily but securely attach the speaker cables to prevent them from coming loose and possibly causing a short; the binding posts are also gold-plated to prevent corrosion and ensure a quality signal is sent over your speaker cables\u003cbr\u003eThe balanced and unbalanced outputs make bi-amping or tri-amping your speakers easier; they can also be used to send the audio signal to a secondary system if your preamplifier does not have enough outputs, or to connect a powered subwoofer. The MC462 sits on a beautiful polished stainless steel chassis and features the timeless McIntosh black glass front panel, illuminated logo, control knobs, aluminum handles and a pair of fast responding blue Watt meters.\u003cbr\u003e\u003cbr\u003e\u003cb\u003eBrand Background:\u003c\/b\u003e\u003cbr\u003eMcIntosh Laboratory is an American manufacturer of handcrafted high-end audio equipment based in Binghamton, New York.

Capacitors are checked for telltale signs of predictive failure including bulging, shrunken wrappers, or physical leakage. We also inspect the PCBs for discoloration from resistors or transistors that may have been running hot. On vintage units we often spot check select capacitors for value and ESR.\u003cbr\u003e\u003cbr\u003eIf the amplifier passes visual inspection, we move on to a controlled power on sequence using a Sencore safety analyzer to monitor current draw in real time. Once the amplifier is determined to be safe to operate, we connect it to full AC mains for function and power testing. We connect the speaker outputs of the amplifier to a Sencore PA81 Power Analyzer which acts as a dummy load, DC offset monitor, and oscilloscope interface. We start with a low level 1 KHz test signal at the amplifier's input and slowly increase its amplitude while monitoring the output on an oscilloscope for signs of noise, clipping, distortion, or improper channel balance. We continue increasing the signal level until the amplifier reaches clipping. \u003cbr\u003e\u003cbr\u003eAt this point we take an output power measurement and compare it to the spec sheet of the amplifier to verify proper performance. If the device under test has both balanced and single ended inputs they are both tested at this time.\u003cbr\u003e\u003cbr\u003eWe finish off the bench evaluation with a 1 KHz square wave check and a 20 Hz to 20 KHz sine sweep to assess the amplifier's frequency response characteristics. \u003cbr\u003e\u003cbr\u003eThis battery of tests will usually reveal if the amplifier has any issues that need further attention.\u003cbr\u003e\u003cbr\u003eBefore the device leaves the bench, we perform a listening test with actual music using a variety of preferred test tracks. Our benches are outfitted with familiar monitor speakers which help us identify inconsistencies that will not always show up on our test gear. The main things that we are listening for are hum or noise with no signal present, proper center image, clicks, pops, or any other obvious undesirable audio characteristics.\u003cbr\u003e\u003cbr\u003eIf the unit passes all of these tests it is moved to our long term testing rig where we simulate real word operating conditions for 6-8 hours minimum. This allows us to monitor the unit for signs of thermal runaway or intermittent issues that only crop up when the unit has fully come up to temperature.\u003c\/p\u003e","brand":"McIntosh","offers":[{"title":"Default Title","offer_id":68024872993022,"sku":"107578","price":11500.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0003\/3275\/9084\/files\/mcintosh-mc462-solid-state-amplifier-quad-balanced-pre-loved-611.jpg?v=1794346761","url":"https:\/\/skyfiaudio.com\/products\/mcintosh-mc462-solid-state-amplifier-quad-balanced-pre-loved-2","provider":"SkyFi Audio","version":"1.0","type":"link"}
