McIntosh MC451, monofoninis stiprintuvas (sujungia 150 vatų lempinį stiprintuvą ir 300 vatų tranzistorinį stiprintuvą viename korpuse)

A Stunning Sound Experience.

The MC451 Dual Mono Amplifier joins the MC901 in offering the ultimate solution to bi-amping a loudspeaker. Like the MC901, the MC451 uses our Hybrid Drive^™ 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 MC451s to your stereo system will allow your prized speakers to perform like never before.

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.

The MC451 features our DualView^™ Power Output Meter. The DualView meter features two of our 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. Each meter operates independently of the other and displays the real time power reading of each amplifier section.

In addition to everything already mentioned, the MC451 comes with a multitude of other McIntosh amplifier the technologies:

Power Guard® monitors and adjusts the input signal in the 300 Watt solid state amplifier section in real time, then makes inconspicuous volume adjustments to prevent harsh sounding distortion and potential speaker damaging clipping.
Power Guard Screen Grid Sensor®(SGS). The 150 Watt vacuum tube amplifier section features our Power Guard SGS® technology. Power Guard SGS helps prevent premature vacuum tube failure by monitoring the screen grid current in the KT88 output vacuum tubes. If the current becomes too high, a circuit in Power Guard SGS is activated which then dynamically attenuates the input signal in real time to keep the vacuum tubes operating at safe levels.
Sentry Monitor™ observes the output current and shuts the amplifier off if it ever exceeds safe limits.
Power Control that can send power on/off signals to other connected McIntosh components for easy system power up and shutdown.
Our patented, gold-plated Solid Cinch™ speaker binding posts that easily and securely attach the speaker cables.
A McIntosh Monogrammed Heatsink™ that is connected to advanced high current output transistors to efficiently cool the solid state amplifier section.
Our Power Management System that will turn the entire unit off after a set amount of time when no input signal has been detected.
McIntosh Solid Cinch speaker binding posts.

The uncompromising fit and finish of the MC451 is highlighted by familiar McIntosh design cues. The front features a signature black glass faceplate with three clear windows that allow viewing of the vacuum tubes, the DualView meter, two rotary control knobs, an illuminated logo and lettering, and built-in aluminum handles. The top is highlighted by a series of block diagrams printed on glass inserts outlining the circuitry and specifications of the unit. All of this sits atop of stainless steel chassis that's been polished to a pristine mirror finish.
