McIntosh Announcement | 30 Sep 2019
Bring home theater dreams to life with the sound quality and power only McIntosh can deliver. McIntosh is proud to announce the new MC257 7-Channel Power Amplifier.
Bring home theater dreams to life with the new McIntosh MC257 7-Channel Power Amplifier.
Experience the latest blockbusters and favorite movies at home like never before with the sound quality and power only McIntosh can deliver.
The MC257 is highlighted by McIntoshs new eye-catching TripleView™ Power Output Meter that independently indicates the real time power reading of the amplifiers three front channels.
The easy-to-read, 15″ (38 cm) wide TripleView meter design is a streamlined approach to the three individual meters found on McIntoshs previous generation 7-channel home theater amplifier.
While a totally new design, each of the three pointers in the TripleView meter have the same inviting motion that McIntosh meters are known for and perform at the same high level as any of their meters.
The captivating look and glow of the TripleView meter is sure to be a conversation starter, but its trademarked blue lighting can be turned off so as not to compete with the TV or movie screen.
In addition to the new TripleView meter, the MC257 features many other upgrades.
When using just the front left, center and right channels, power output has been increased by 25% from 200 Watts per channel to 250 Watts per channel.
When using all 7 channels, each will receive a healthy 200 Watts per channel. Regardless of how many channels are used, the full 200 or 250 Watts is delivered to either 4 or 8 Ohm speakers via McIntoshs Dynamic Power Manager®(DPM) technology.
Filter capacity has been increased by 20% which has produced an amazing 94% increase in dynamic headroom from 1.7dB to 3.3dB as well as improving low frequency performance both key features in a home theater amplifier, especially when listening to an energetic soundtrack.
Also new to the MC257 are five McIntosh Monogrammed Heatsinks™ which are connected to advanced high current output transistors to efficiently and silently cool the amplifier; as a result, noisy cooling fans that can interfere with the movie soundtrack are not needed.
A quiet, specially wound toroidal isolation power transformer also helps keep noise to a minimum. Speaker terminals have been updated to McIntoshs standard gold-plated binding posts.
McIntoshs power management system that will turn the amplifier off after a set amount of time when no input signal has been detected has also been added.
Finally, the front panel is now lit by direct LED backlighting for improved color accuracy and durability.
Besides all these upgrades, the MC257 comes with steadfast McIntosh technologies like Power Guard® to prevent potential speaker damage caused by clipping and over-driving of the amplifier. Sentry Monitor™ technology that protects against short-circuits by disengaging the output stage should the current ever exceed safe operating levels (it then resets automatically when operating conditions return to normal) is also included.
Both balanced and unbalanced inputs are included to connect the MC257 to a home theater processor.
The MC257 can be utilized in many ways: it can power a 7-channel home theater by itself; it can be paired with either McIntoshs MI128 8-channel or MI254 4-channel digital amplifiers in home theaters that have more than 7-channels; or it can be used in 5-channel home theaters with 2 of its channels available to power a second audio zone.
The MC257 sits on a polished stainless steel chassis and bears the classic McIntosh design of a black glass front panel with the TripleView meter, illuminated logo, control knobs, and aluminum end caps.
