The fully loaded, hybrid MA12000 Integrated Amplifier is a product of uncompromising audio engineering and expert craftsmanship. Our most powerful integrated amplifier ever, the feature rich MA12000 offers 350 Watts per channel of clean, high performance power that produces a breathtaking home audio experience. You will think your favorite musicians are playing a live, in-person performance in your house.
The MA12000 gives you the best of all worlds with the warm nuances of a vacuum tube preamplifier (or valve preamplifier as some of our friends like to say) combined with the speed and raw power of a solid state amplifier, state-of-the-art digital audio capabilities, and enough analog audio connections for virtually any home music system.
The MA12000 is a hybrid design with the preamplifier section powered by (4) 12AX7A vacuum tubes (2 tubes per audio channel), while the 350 Watt power amplifier section employs a solid state design. Our Autoformer™ technology guarantees your speakers will always be capable of receiving that full 350 Watts whether they have 2, 4 or 8 Ohm impedance.
There are 10 analog inputs on the MA12000 consisting of 2 balanced and 6 unbalanced inputs, plus 1 Moving Coil and 1 Moving Magnet input for connecting a turntable. Both phono inputs feature adjustable loading for fine tuning the MA12000 to your specific turntable configuration so your vinyl collection sounds just right. All the unbalanced analog connectors are constructed from premium gold-plated solid brass for superior signal handling and grounding. The MA12000 also has 1 balanced and 1 unbalanced output if you ever want to connect to an additional amplifier that's used in a different part of your residence.
Other MA12000 features include:
- Power Guard® that monitors the output signal for over driving and makes real time micro adjustments to the input signal to prevent harsh sounding clipping that could potentially damage your speakers
- Our fuse-less short-circuit protection circuit Sentry Monitor™ that disengages the output stage before current exceeds safe operating levels and then resets automatically when operating conditions return to normal
- A pair of peak responding, trademarked "McIntosh Blue" Watt meters that indicate the real time power output of each audio channel
- McIntosh Monogrammed Heatsinks™ which are connected to advanced high current output transistors that minimize thermal equilibrium lag (or warm-up) time and help keep the MA12000 running cool
- Home Theater PassThru that allows for seamless integration into a home theater system
- A discrete, eight-band tone control that allows for advanced manual analog adjustment of your favorite recordings
- High Drive headphone amplifier with Headphone Crossfeed Director (HXD®) which can bring an added dimension to headphone listening
- Power Control to send power on/off signals to connected McIntosh components for easy system power up and shutdown
- Doubling of filter capacity compared to our other integrated amplifiers for even better low frequency performance
- The latest audio-grade circuit components to deliver the best sound possible
- Powerful control microprocessors to improve overall system operation
- Easy operation via front panel controls or the included comprehensive remote control
