The McIntosh C12000 is a high-end, two-chassis preamplifier designed for ultimate stereo separation and sonic purity. The C12000 consists of the C12000 Controller module and the C12000 Preamplifier module, which are connected via high-performance, shielded umbilical cables. All power control, data ports, and external control connections are located in the C12000 Controller, while the C12000 Preamplifier houses the audio connections and circuitry. The two units are designed to act as one, providing easy control and operation.
The C12000 Preamplifier module offers a total of 12 analog inputs, including six balanced inputs, four unbalanced inputs, and two unbalanced phono inputs. The phono inputs are configurable as either Moving Coil or Moving Magnet, with adjustable capacitance and resistance loading, as well as adjustable gain in 6dB steps from 40dB to 64dB. This allows for maximum flexibility and the ability to customize the preamplifier to best fit your turntable, cartridge, and vinyl collection.
The C12000 utilizes McIntosh's Hybrid Drive™ technology, which combines the best of vacuum tube and solid-state technology to produce exceptional sound performance. The preamplifier offers both vacuum tube and solid-state output options, allowing you to choose based on the music being played, the audio components in your home audio system, and your personal preferences. All outputs are driven by discrete amplifiers, ensuring high-quality sound reproduction.
For vacuum tube output, the C12000 uses six tubes or valves to power the high-level preamplifier section, with two 12AT7 tubes and one 12AX7A tube assigned to each the left and right channel. Solid state output is handled by a discrete balanced op-amp. The phono stage, regardless of the chosen output option, uses four 12AX7A vacuum tubes in a fully balanced configuration that incorporates RIAA equalization.
The C12000 preamplifier is designed to deliver the pinnacle of high-quality and balanced audio performances. Its stainless steel and black titanium chassis are polished to a mirror finish, and its front panel features the classic McIntosh black glass, blue meters, and illuminated logos. This preamplifier can be easily integrated with other McIntosh products. With its striking design and superior sound quality, the C12000 is a must-have for audio enthusiasts.
