The MC451 - Dual Mono Amplifier
The MC451 Dual Mono Amplifier joins the MC901 in offering the ultimate solution to bi-amping a loudspeaker. Like the MC901, the MC451 uses Hybrid DriveTM technology that combines a separate vacuum tube and solid state amplifier onto one single chassis to produce the best possible sound performance from a bi-ampable speaker. Unlike the larger MC901, the MC451 has a more conventional McIntosh form factor and size, allowing it to fit into home audio systems, racks, and furniture more easily. Adding a pair of MC451 to your stereo system will allow your prized speakers to perform like never before.
The MC451 consists of a 150 Watt vacuum tube amplifier and a 300 Watt solid state amplifier, which is more than enough power to drive virtually all speakers. The vacuum tube section drives the speaker's midranges and tweeters, while the solid state section drives the woofers.
The 150 Watt vacuum tube amplifier is powered by four KT88 output tubes which are located under a removable wire cage, plus two 12AT7 and one 12AX7A signal tubes; it uses patented Unity Coupled Circuit output transformer to deliver its full 150 Watts into almost any speaker regardless if it has 2, 4 or 8 Ohm impedance. Similarly, the 300 Watt solid state amplifier delivers its full 300 Watts into a 2, 4 or 8 Ohm impedance speaker via AutoformerTM technology.
The two amplifiers in the MC451 are designed to work together in a synergistic relationship and are specifically engineered to assure that each only amplifies its intended frequencies. The large but quiet toroidal transformer generates enough power so that neither amplifier robs power or performance from the other. All of this results in easy bi-amping with unparalleled performance and sound reproduction from your speakers.
MC451 features DualViewTM Power Output Meter. The DualView meter features two of traditional, fast responding mechanical meters stacked above and below each other in a single meter window; one meter is dedicated to the 150 Watt vacuum tube amp and the other to the 300 Watt solid state amp.
