■ The C12000 Preamplifier is the next generation of our acclaimed twochassis 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.
