c1000
Configurable Tube/Solid-State Controller
and Preamplifier
The McIntosh C1000 stereo preamplifier is a fully balanced, dual-mono design.
A separate power supply chassis houses all microprocessor and control circuits providing
a high degree of isolation for the audio stages. Available with solid-state and tube preampli-
fier electronics which may be used individually or together, the C1000 preamplifier marries
outstanding audio performance with flexible user-programmability in a one-of-a-kind
three-chassis solution.
Moving Coil and Moving Magnet phono preamplifiers are supported in both the solid-state
and tube designs. Both feature high open-loop gain enabling the use of negative feedback
around the compensation amplifiers for very low noise and distortion and markedly
improved RIAA performance.
The C1000 volume control is a balanced design with a logic-controlled audio taper.
This custom attenuator is accomplished via a 4-stage, digitally controlled analog circuit
that operates with 16 bit precision. Exceptional tracking accuracy guarantees that common
noise and distortion rejection are maximized. The second stage of this control adjusts the
gain of the output amplifier towards unity as the attenuation of the first stage is increased.
The result is very low distortion and wide dynamic range.
The C1000 configurable tube/solid state controller and preamplifier is available
exclusively through McIntosh Authorized Premier Dealers.
