McIntosh MC451 1-Channel Power Amplifier
£19,490.00
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.
Description
The McIntosh MT-10 marries classic McIntosh glass front panel cosmetics with serious
mechanics to create a unique, ready-to-play LP solution. With tracking force, anti-skate
and cartridge position preset at the factory the McIntosh MT-10 delivers high performance
LP playback with minimal set up.
The turntable base is comprised of a damped sandwich of stainless steel and acrylic plate;
a unique combination of dissimilar materials that provides a resonance-free foundation
for the tonearm. A massive, 12 pound, 2 ½” thick acrylic platter spins on a cushion of air,
elevated by a custom magnetic bearing.
A regulated power supply drives a super-quiet, brushless, Swiss DC motor. Unmatched
accuracy is derived from a new electronic speed control that references 1,595 strobe
markings per revolution of the platter. Speed adjustments of 331/3, 45, or 78 RPM are
made from the front panel and are registered on a blue, backlit McIntosh meter.
A custom tonearm features a rigid, dural-aluminium arm-tube gimbaled in two sapphire
(horizontal) and two ceramic (vertical) bearings for the least possible friction. A .5mV
moving coil cartridge is included, and features an ebony body with an elliptical stylus.
- Power Guard® that 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.
