Overview<\/h4>\n

It has installer-friendly physical dimensions and is 2U rack mountable via the included mounting ears (the mounting ears are removable for non-rack installations). As a highly efficient Class D amplifier, it does not require noisy cooling fans to maintain nominal operating temperature. In addition to distributed audio use, the MI254<\/strong> is well suited for home theaters to drive surround sound speakers and could be integrated into virtually any existing home theater system.<\/p>\n

On the front panel are two blue McIntosh<\/strong> Watt Meters that display the summed power output of channels 1 + 2 and channels 3 + 4. Multi-color LED indicators display the status of each channel. The back panel includes both a balanced and unbalanced input for each channel along with our standard 5-way speaker binding posts.<\/p>\n

Other features that come with the MI254<\/strong> are: Power Guard\u00ae signal overload technology that prevents overdriving the speakers; our Sentry Monitor\u2122 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; BUS input & outputs to easily distribute a stereo signal to multiple outputs and\/or multiple amplifiers; individual channel inputs; 12 Volt triggering capabilities; and eco-friendly on\/off signal sensing that turns the unit off if no input signal has been detected for a set amount of time or automatically turns the amp on when it senses a signal.<\/p>\n

The MI254<\/strong> includes many McIntosh<\/strong> design cues including a black glass front panel, blue Watt meters, an illuminated McIntosh<\/strong> logo, and a familiar form factor highlighted by silver trim.<\/p>\n

The MI254<\/strong> 4-channel digital power amplifier is a versatile multi-channel amplifier ideal for use in distributed audio, home theater or 2-channel stereo playback. It delivers 250 Watts into 8 Ohm speakers or 300 Watts into 4 Ohm speakers via its highly sophisticated closed loop digital switching amplifiers. These amplifiers are paired with extremely robust power supplies that produce performance levels rarely achieved in distributed audio.<\/p>\n","protected":false},"featured_media":46552,"template":"","meta":{"_acf_changed":false},"product_brand":[858],"product_cat":[315],"product_tag":[],"class_list":{"0":"post-46550","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_brand-mcintosh","7":"product_cat-power-amplifiers","9":"first","10":"instock","11":"taxable","12":"shipping-taxable","13":"purchasable","14":"product-type-simple"},"acf":[],"jetpack_sharing_enabled":true,"_links":{"self":[{"href":"https:\/\/hifimarket.ee\/et\/wp-json\/wp\/v2\/product\/46550","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/hifimarket.ee\/et\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/hifimarket.ee\/et\/wp-json\/wp\/v2\/types\/product"}],"version-history":[{"count":0,"href":"https:\/\/hifimarket.ee\/et\/wp-json\/wp\/v2\/product\/46550\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/hifimarket.ee\/et\/wp-json\/wp\/v2\/media\/46552"}],"wp:attachment":[{"href":"https:\/\/hifimarket.ee\/et\/wp-json\/wp\/v2\/media?parent=46550"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/hifimarket.ee\/et\/wp-json\/wp\/v2\/product_brand?post=46550"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/hifimarket.ee\/et\/wp-json\/wp\/v2\/product_cat?post=46550"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/hifimarket.ee\/et\/wp-json\/wp\/v2\/product_tag?post=46550"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
