Four 12AX7A tubes handle preamplification, while the power amplifier delivers 350 W per channel into 2, 4, or 8 ohms through McIntosh Autoformers, allowing its full rated power to be delivered across all three speaker impedances.\u003c\/p\u003e\u003cp\u003eTen analog inputs include two balanced, six unbalanced, and dedicated Moving Coil and Moving Magnet phono inputs. Both phono stages offer adjustable loading for matching a wide range of cartridges. An eight-band analog equalizer provides additional tonal adjustment and can be bypassed when not required.\u003c\/p\u003e\u003ch4\u003eDA2 Digital Audio Module\u003c\/h4\u003e\u003cp\u003eThe factory-installed DA2 Digital Audio Module adds seven digital inputs: two coaxial, two optical, USB, MCT, and an audio-only HDMI ARC connection. Its Quad Balanced eight-channel, 32-bit DAC supports PCM up to 32-bit\/384 kHz through USB, along with DSD512 and DXD384. Coaxial and optical inputs support PCM up to 24-bit\/192 kHz.\u003c\/p\u003e\u003cp\u003eHDMI ARC allows a compatible television to feed audio directly to the MA12000, with support for two-channel playback of compatible Dolby and DTS formats. With CEC enabled, a compatible TV remote can control amplifier power and volume. The DA2 module is replaceable, allowing the digital section to be upgraded if McIntosh develops future modules.\u003c\/p\u003e\u003ch4\u003eMcIntosh Power and Protection\u003c\/h4\u003e\u003cp\u003ePower Guard monitors the output signal and adjusts the input level to prevent clipping, while Sentry Monitor provides fuse-less protection against excessive operating current. Monogrammed heatsinks help dissipate heat from the high-current output transistors, and Solid Cinch speaker binding posts provide secure connections for speaker cables.\u003c\/p\u003e\u003cp\u003eA High Drive headphone amplifier with Headphone Crossfeed Director (HXD) is included for headphone listening, while Home Theater PassThru allows the MA12000 to be incorporated into a multichannel system. Power Control connections, Data Ports, RS232 control, input level matching, and a rear-panel IR sensor input provide additional system integration options.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cp\u003e\u003cb\u003ePower Output per Channel:\u003c\/b\u003e 350 W into 2, 4, or 8 ohms\u003c\/p\u003e\u003cp\u003e\u003cb\u003eNumber of Channels:\u003c\/b\u003e 2\u003c\/p\u003e\u003cp\u003e\u003cb\u003eRated Power Band:\u003c\/b\u003e 20 Hz to 20 kHz\u003c\/p\u003e\u003cp\u003e\u003cb\u003eTotal Harmonic Distortion (Preamplifier \/ Amplifier):\u003c\/b\u003e 0.03% \/ 0.005%\u003c\/p\u003e\u003cp\u003e\u003cb\u003eDynamic Headroom:\u003c\/b\u003e 1.5 dB\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFrequency Response \u003cb\u003e(+0, -0.5 dB)\u003c\/b\u003e:\u003c\/b\u003e 20 Hz to 20 kHz\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFrequency Response \u003cb\u003e(+0, -3 dB)\u003c\/b\u003e:\u003c\/b\u003e 10 Hz to 100 kHz\u003c\/p\u003e\u003cp\u003e\u003cb\u003ePhono Sensitivity (MC, MM):\u003c\/b\u003e 0.30 mV, 3.0 mV\u003c\/p\u003e\u003cp\u003e\u003cb\u003eHigh-Level Sensitivity (Balanced \/ Unbalanced):\u003c\/b\u003e 600 mV \/ 300 mV\u003c\/p\u003e\u003cp\u003e\u003cb\u003ePower Amplifier Input Sensitivity:\u003c\/b\u003e 1.7 V\u003c\/p\u003e\u003cp\u003e\u003cb\u003eSignal-to-Noise Ratio (MC, MM):\u003c\/b\u003e 75 dB, 77 dB\u003c\/p\u003e\u003cp\u003e\u003cb\u003eSignal-to-Noise Ratio (High Level \/ Power Amplifier):\u003c\/b\u003e 95 dB \/ 114 dB\u003c\/p\u003e\u003cp\u003e\u003cb\u003eInput Impedance (Balanced \/ Unbalanced):\u003c\/b\u003e 44 kohms \/ 22 kohms\u003c\/p\u003e\u003cp\u003e\u003cb\u003eDamping Factor:\u003c\/b\u003e \u0026gt;40\u003c\/p\u003e\u003cp\u003e\u003cb\u003eMaximum Output Voltage (Balanced \/ Unbalanced):\u003c\/b\u003e 16 V \/ 8 V\u003c\/p\u003e\u003cp\u003e\u003cb\u003eBalanced Inputs:\u003c\/b\u003e 2\u003c\/p\u003e\u003cp\u003e\u003cb\u003eUnbalanced Inputs:\u003c\/b\u003e 6\u003c\/p\u003e\u003cp\u003e\u003cb\u003ePhono Inputs:\u003c\/b\u003e 1 Moving Coil (adjustable); 1 Moving Magnet (adjustable)\u003c\/p\u003e\u003cp\u003e\u003cb\u003eDigital Inputs:\u003c\/b\u003e 2 coaxial, 2 optical, 1 MCT, 1 USB, 1 HDMI ARC\u003c\/p\u003e\u003cp\u003e\u003cb\u003eBalanced Variable Outputs:\u003c\/b\u003e 1\u003c\/p\u003e\u003cp\u003e\u003cb\u003eUnbalanced Outputs:\u003c\/b\u003e 1 fixed, 1 variable\u003c\/p\u003e\u003cp\u003e\u003cb\u003eHeadphone Output:\u003c\/b\u003e 1\/4\" High Drive with Headphone Crossfeed Director (HXD)\u003c\/p\u003e\u003cp\u003e\u003cb\u003eDAC:\u003c\/b\u003e Quad Balanced 8-channel, 32-bit\/384 kHz PCM\/DSD\u003c\/p\u003e\u003cp\u003e\u003cb\u003eCoaxial \/ Optical Input:\u003c\/b\u003e PCM up to 24-bit\/192 kHz\u003c\/p\u003e\u003cp\u003e\u003cb\u003eMCT Input:\u003c\/b\u003e 16-bit\/44.1 kHz PCM, DSD64\u003c\/p\u003e\u003cp\u003e\u003cb\u003eUSB Input:\u003c\/b\u003e PCM up to 32-bit\/384 kHz; DSD64, DSD128, DSD256, DSD512; DXD352.8, DXD384\u003c\/p\u003e\u003cp\u003e\u003cb\u003eTone Controls:\u003c\/b\u003e 8-band analog equalizer\u003c\/p\u003e\u003cp\u003e\u003cb\u003eTone Bypass:\u003c\/b\u003e Yes\u003c\/p\u003e\u003cp\u003e\u003cb\u003eHome Theater PassThru:\u003c\/b\u003e Yes\u003c\/p\u003e\u003cp\u003e\u003cb\u003ePower Control Outputs:\u003c\/b\u003e 1 main, 2 trigger\u003c\/p\u003e\u003cp\u003e\u003cb\u003eRear-Panel Data Ports:\u003c\/b\u003e 4\u003c\/p\u003e\u003cp\u003e\u003cb\u003eRS232 Control:\u003c\/b\u003e Yes\u003c\/p\u003e\u003cp\u003e\u003cb\u003eVacuum Tubes:\u003c\/b\u003e 4 x 12AX7A\u003c\/p\u003e\u003cp\u003e\u003cb\u003eOutput Type:\u003c\/b\u003e Autoformer\u003c\/p\u003e\u003cp\u003e\u003cb\u003eDimensions (H × W × D):\u003c\/b\u003e 9-7\/16\" × 17-1\/2\" × 19-3\/4\" (240 × 445 × 502 mm)\u003c\/p\u003e\u003cp\u003e\u003cb\u003eWeight:\u003c\/b\u003e 108 lb.
