MC257 7-Channel Power Amplifier

Ideal for Home Theater Systems

Bring your home theater dreams to life with the MC257 7-Channel Power Amplifier. Experience the latest blockbusters along with your favorite movies like never before in your home theater with the sound quality and power only McIntosh can deliver.

The MC257 is highlighted by our new eye-catching TripleView™ Power Output Meter that independently indicates the real time power reading of the amplifier’s 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 our previous generation 7-channel home theater amplifier. Instead of three separate meter windows each housing a single meter, the TripleView features three of our traditional mechanical meters in a single meter enclosure.

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 our 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 your 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 our 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.
