BRAND: McIntosh
SERIES: C12000 Stereo Preamplifier
TYPE: Preamplifier
OVERVIEW
- The C12000 Preamplifier is the next generation of our acclaimed two-chassis preamplifier design. This unusual but effective design allows the audio section to be completely separated from the control and power section, delivering the purest sound reproduction possible.
- Inside each the C12000C Controller and C12000ST Preamplifier, the left and right channels are electrically and mechanically isolated from each other to allow for true dual mono operation.
- Includes 12 analog inputs: six balanced, four unbalanced, and two unbalanced phono inputs. The phono inputs are no longer set up as dedicated for Moving Coil or Moving Magnet cartridges; instead, both are configurable as either Moving Coil or Moving Magnet with adjustable Capacitance and Resistance Loading, along with adjustable Gain.
- Offers both vacuum tube and solid-state output. Six vacuum tubes 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 via a discrete balanced op-amp. Phono stage utilizes four 12AX7A vacuum tubes, with two tubes used per channel in a fully balanced configuration that incorporates RIAA equalization.
- Four total outputs: one balanced vacuum tube; one balanced solid-state; one fixed unbalanced; and one programmable unbalanced (can be either vacuum tube or solid-state).
- Other features: High Drive headphone amplifier that has plenty of power and flexibility to drive a wide range of headphones. Power Control can automatically turn other connected McIntosh components on and off. Data Ports can send remote control commands to connected sources
