McIntosh MA12000 Integrert superforsterker med rør og DAC 2x350w

McIntosh MA12000 Integrated Amplifier
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.
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.

McIntosh MA12000 Integrated Amplifier
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.
