The McIntosh MA12000 is a hybrid integrated amplifier that delivers 350 watts per channel. It uses Hybrid Drive technology, which pairs a vacuum tube preamplifier with a solid state power amplifier. The preamp section uses four 12AX7A tubes, two per channel. Autoformer technology lets the amp deliver its full 350 watts into speakers of 2, 4 or 8 ohms.
It has 10 analog inputs: 2 balanced, 6 unbalanced, and separate moving coil and moving magnet phono inputs. Both phono inputs have adjustable loading to match a turntable setup. The unbalanced analog connectors are gold-plated solid brass. One balanced and one unbalanced output can feed an additional amplifier.
The DA2 Digital Audio Module comes factory installed and adds 7 digital inputs. It uses a Quad Balanced, 8-channel, 32-bit DAC. The HDMI ARC input connects a TV with a compatible HDMI ARC output so its audio plays through the stereo system.
