McIntosh MC255 Multi-channel power amplifier
Give your home theater the power it deserves with the MC255 5-channel home theater amplifier. The MC255 features a striking new TripleView current output meter that independently displays the real-time power reading of the amplifier's three front channels. Instead of three separate meter windows, this model has three traditional mechanical meters in one housing on the easy-to-read 38cm wide TripleView screen. Although this is a completely new design, all three highly responsive pointers have the same attractive movement and sure-fire functionality that McIntosh meters are known for. The TripleView gauge's glamorous look, welcoming glow and trademark blue lighting can be turned off so it doesn't compete with a TV or movie screen.
In addition to the new instrument panel, the MC255 has received many other performance-enhancing upgrades to provide an unforgettable cinema experience in your home theater. The filter capacity has been increased by 50%, which has more than doubled the dynamic headroom from 1.7dB to 3.6dB, improving low frequency performance. When using only the left, center and right channels, the power has increased by 25% from 200 watts per channel to 250 watts per channel. Regardless of the number of channels used, all 200 or 250 watts are delivered to either 4 or 8 ohm speakers via McIntosh's Dynamic Power Manager technology.
The MC255 runs cool and quiet thanks to four McIntosh Monogrammed Heatsinks connected to advanced high current output transistors that effectively cool the amplifier. The speaker connectors have been upgraded with gold-plated binding posts to prevent corrosion and ensure a high-quality signal is sent to your home theater speakers. Traditional McIntosh knobs adorn the front panel for controlling the meter lights and power function. A direct LED backlight has been added to the front panel to improve color accuracy and durability. An environmentally friendly power management system turns off the amplifier after a certain period of time when no input signal is detected.
