McIntosh MC451 Dual Mono Amplifier


Recommended Posts

Regalo di Natale di McIntosh.

Da quanto ho compreso, ma non vorrei dire castronerie, essendo un amplificatore ibrido, si può scegliere se utilizzarlo con le valvole (150W) oppure a stato solido (300W).

Attendo Vincenzo, che, sicuramente - almeno spero - potrà dirci qualcosa in più.

Ciao e buon proseguimento di giornata.

Ne stavamo parlando già qualche settimana orsono:

Devo dire che è proprio spettacolare....300 watt a ss per le vie basse e 150 watt a valvole per le medioalte. Un 901 in "miniatura"

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 our 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 our Autoformer™ 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.

 

Bi-amping your speakers with the MC451 is easy. No longer do you need fiddle with two separate amplifiers, an external crossover, and a lot of trial and error to properly configure the two separate amplifiers with often times only so-so results. The MC451 solves these hassles thanks to its internal, adjustable crossover. The MC451’s crossover tailors the output frequency range of each amplifier section to the attached loudspeaker. Simply set the CROSSOVER POINT knob on the back of the MC451 to the loudspeaker’s crossover point, then frequencies below the crossover point will be sent to the solid state amplifier and frequencies above it will be sent to the vacuum tube amplifier.

This adjustable crossover allows you to optimize the performance of both amplifier sections to your speaker's specifications and to your listening preferences. Gain levels for the vacuum tube amplifier can be adjusted from -6dB to +3dB. A direct feed can also be connected to each amplifier section, thus bypassing the internal crossover.

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.
