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 includes our Hybrid Drive™ technology that uses the best of vacuum tubes and solid state to produce the best sound performance. It gives you 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. 
 
The vacuum tubes for the preamplifier section are located between the Watt meters. Also shown are the knobs for the eight-band analog tone control.
 
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.

For digital music, the MA12000 comes with our DA2 Digital Audio Module factory installed. Located in the DA2 are 7 digital audio inputs: 2 coaxial, 2 optical, 1 USB and 1 MCT (for use with our MCT series of SACD/CD Transports), and 1 audio-only HDMI Audio Return Channel (ARC)1 connection. The DA2 is powered by a next generation, Quad Balanced, 8-channel, 32-bit Digital-to-Analog Converter (DAC). This audiophile-grade DAC features improved dynamic range and improved total harmonic distortion. The DA2 supports high resolution digital audio playback, as the USB input supports native playback of up to DSD512 and DXD up to 384kHz, while the coax and optical inputs can decode digital music up to 24-bit/192kHz.
 
The DA2 has received Roon Tested designation from Roon Labs, which can be especially useful if you have an extensive library of digital music. As a Roon Tested partner, McIntosh has provided equipment to Roon for testing with a variety of different operating systems and computers, and shared information about its design and capabilities.
 
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
