It is a strong fit for installations that need fewer channels with more power per speaker. An eight-channel amplifier is generally better suited to a larger number of lower-demand distributed-audio zones, while a seven-channel theater amplifier may be preferable when most of the surround system must be powered from a single chassis.\u003c\/p\u003e\n\u003ch3\u003eMcIntosh MI254 Specifications\u003c\/h3\u003e\n\u003ctable\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth\u003eAmplifier Type\u003c\/th\u003e\n\u003ctd\u003e4-channel digital Class D power amplifier\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003ePower Output per Channel\u003c\/th\u003e\n\u003ctd\u003e250 watts into 8 ohms; 300 watts into 4 ohms\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eNumber of Channels\u003c\/th\u003e\n\u003ctd\u003e4\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eTotal Harmonic Distortion\u003c\/th\u003e\n\u003ctd\u003e0.025%\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eSignal-to-Noise Ratio\u003c\/th\u003e\n\u003ctd\u003e100dB below rated output\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eDynamic Headroom\u003c\/th\u003e\n\u003ctd\u003e2.5dB at 8 ohms; 3.5dB at 4 ohms\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eDamping Factor\u003c\/th\u003e\n\u003ctd\u003eGreater than 85 at 8 ohms; greater than 45 at 4 ohms\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eRated Power Band\u003c\/th\u003e\n\u003ctd\u003e20Hz to 20kHz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eFrequency Response\u003c\/th\u003e\n\u003ctd\u003e+0\/-0.9dB from 20Hz to 20kHz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eCircuit Configuration\u003c\/th\u003e\n\u003ctd\u003eClosed-loop digital switching\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eOutput Type\u003c\/th\u003e\n\u003ctd\u003eDirect coupled\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eBalanced Inputs\u003c\/th\u003e\n\u003ctd\u003e4 XLR\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eUnbalanced Inputs\u003c\/th\u003e\n\u003ctd\u003e4 RCA plus stereo BUS input and output\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eSpeaker Connections\u003c\/th\u003e\n\u003ctd\u003eStandard 5-way binding posts\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003ePower Control\u003c\/th\u003e\n\u003ctd\u003e12-volt trigger and automatic signal sensing\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eProtection\u003c\/th\u003e\n\u003ctd\u003ePower Guard® and Sentry Monitor™\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eMeters\u003c\/th\u003e\n\u003ctd\u003eTwo blue Watt Meters displaying summed output for channels 1 + 2 and 3 + 4\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eCooling\u003c\/th\u003e\n\u003ctd\u003eFanless\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eRack Mounting\u003c\/th\u003e\n\u003ctd\u003e2U with removable rack ears\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eBTU Rating\u003c\/th\u003e\n\u003ctd\u003e1,000 BTU per hour\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eDimensions\u003c\/th\u003e\n\u003ctd\u003e17-1\/2 inches W without ears \/ 19 inches W with ears x 4-5\/16 inches H x 21 inches D\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eUnit Weight\u003c\/th\u003e\n\u003ctd\u003e23.5 lbs\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eShipping Weight\u003c\/th\u003e\n\u003ctd\u003e40 lbs\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eWarranty\u003c\/th\u003e\n\u003ctd\u003e3-year limited warranty\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003ch4\u003eCan the McIntosh MI254 be used for Dolby Atmos speakers?\u003c\/h4\u003e\n\u003cp\u003eYes.

The MC2301 is designed to provide both. Its 300-watt output gives it the headroom needed for large listening rooms, wide dynamic swings, and loudspeakers that require substantial current and control.
