The McIntosh MC255 5-Channel Solid State Amplifier is the ultimate solution for home theater enthusiasts who demand nothing but the best in audio performance. With a remarkable 250 Watts per channel for 3 channels and 200 Watts per channel for 5 channels, the MC255 ensures your home theater system delivers powerful, immersive sound, whether you're watching movies, playing video games, or enjoying your favorite music.
The MC255 is designed to deliver an unforgettable cinema experience in your home. With its increased filter capacity and dynamic headroom, the MC255 provides the extra power needed to handle the most demanding soundtracks. Whether you're using the amplifier for a full 5-channel home theater setup or focusing on the front left, right, and center channels, the MC255 ensures every note, dialogue, and sound effect is reproduced with stunning clarity and impact.
The MC255 introduces the revolutionary TripleView™ Power Output Meter, a unique feature that displays the power output of the amplifier’s three front channels in real-time. This 15” wide meter brings together three traditional McIntosh mechanical meters into one, providing an easy-to-read and visually striking display. The meters’ signature blue lighting adds a touch of elegance to your setup, but can be turned off to avoid any distractions during your viewing experience.
Unlike many other amplifiers, the MC255 operates cool and quiet thanks to four McIntosh Monogrammed Heatsinks™ connected to advanced high-current output transistors. These features eliminate the need for noisy cooling fans, ensuring that nothing interrupts your movie’s soundtrack. The toroidal isolation power transformer also minimizes noise, while the gold-plated binding posts ensure a pristine signal is sent to your speakers.
The MC255 offers versatile installation options, making it ideal for a wide range of home theater configurations. It can power a conventional 5-channel setup or be paired with additional McIntosh amplifiers for expanded systems featuring Dolby® Atmos, DTS:X™, and Auro-3D® object-based 3D audio formats. The MC255 can also be configured for dual-zone use, delivering 250 Watts to one zone and 200 Watts to another, offering flexibility and powerful performance throughout your home.
The McIntosh MC255 stands out not just for its power and performance, but also for its innovative features and classic McIntosh design. Whether you're upgrading an existing home theater system or building one from scratch, the MC255 provides the power, precision, and reliability needed to create a truly immersive audio experience. Its combination of advanced technologies, like Dynamic Power Manager® and Power Guard®, with timeless aesthetics ensures that the MC255 will be the centerpiece of any high-end home theater setup.
