Introduction
The McIntosh C1100 Tube Preamplifier is one of the
finest Preamplifiers ever created with connections for
both analog and digital sources. The C1100T Outputs
have the ability to drive multiple Power Amplifiers.
The C1100 Audio Reproduction is sonically transparent and absolutely accurate. The McIntosh Sound is
“The Sound of the Music Itself.”
Performance Features
• Dual Chassis with Dual Mono Design
The Dual Chassis design completely separates all
power supply, microprocessor and control circuits
from the pure audio circuits for total noise isolation.
To further aid in channel isolation, the circuitry for
both channels is totally separate, physically isolated
and shielded. The C1100C incorporates two identical
power supplies one for each channel, to help assure
total channel isolation.
• Fully Balanced Circuitry
The C1100T utilizes the very latest in Fully Balanced
Circuitry from the Input Connectors all the way to the
Output Connectors for the lowest possible noise and
distortion.
• Electromagnetic Input Switching with Level Trim
Adjustment
Digital Logic integrated circuits drive Electromagnetic Switches on all Inputs and operating functions
for reliable, noiseless, distortion free switching. All
the Inputs on the C1100T can be matched in level, so
there are no abrupt changes in volume levels between
the different Inputs.
• Moving Coil and Moving Magnet Phono Inputs
The C1100T has two precision Phono Preamplifier
Circuits, one for Moving Coil Phono Cartridges and
the other for Moving Magnet Cartridges. Both phono
inputs have selectable loading. The circuits use the
latest designs providing the lowest possible noise and
distortion. The close tolerance resistors and capacitors
used in the RIAA Correction Equalization Circuitry
provide an extremely flat frequency response.
• Balanced Inputs
The Balanced Inputs allow the connection of a source
component using long cable lengths without a loss in
sound qu a l it y.
• Precision Tracking Volume Control
Volume levels are controlled by a Precision Balanced
Digitally Controlled Attenuator System with an Optical Encoder Rotary Control. This assures a 0.1dB
tracking accuracy between channels. There are 214
individual 0.5dB volume level steps with no noise as
the volume level is changed.
• Variable Rate Volume and Balance Controls
The C1100T Preamplifier’s Volume and Balance
Control Circuitry provides an ideal rate of change with
control rotation.

Input/Output is selected.
• Dual Special Power Supply
Two fully separate and regulated Power Supplies with
special R-Core Power Transformers ensure stable
noise free operation even though the power line varies.
• LED Front Panel Illumination
The even Illumination of the Front Panel is accomplished by multiple extra long life Light Emitting
Diodes (LEDs) arranged with a special orientation.
• Glass Front Panel and Super Mirror Chassis
Finish
The famous McIntosh Illuminated Glass Front Panel
and the Lower Chassis are Stainless Steel with a
Mirror Finish. The Upper Chassis and Top Cover is
hairline brushed black Titanium Stainless Steel Finish.

Installation
The C1100C can be placed upright on a table or
shelf, standing on its four feet. It also can be custom
installed in a piece of furniture or cabinet of your
choice. The four feet may be removed from the bottom
of the C1100C when it is custom installed as outlined
below. The four feet together with the mounting
screws should be retained for possible future use if the
C1100C is removed from the custom installation and
used free standing. The required panel cutout, ventilation cutout and unit dimensions are shown.
Always provide adequate ventilation for your
C1100C. Cool operation ensures the longest possible
operating life for any electronic instrument. Do not
install the C1100C directly above a heat generating
component such as a high powered amplifier. Also
do not stack the C1100T on top of the C1100C. If all
the components are installed in a single cabinet, a
quiet running ventilation fan can be a definite asset in
maintaining all the system components at the coolest
possible operating temperature.
A custom cabinet installation should provide the
following minimum spacing dimensions for cool
operation.
Allow at least 6 inches (15.2cm) above the top, 2
inches (5.1cm) below the bottom and 1 inch (2.5cm)
on each side of the Preamplifier, so that airf low is not
obstructed. Allow 20 inches (50.8cm) depth behind the
front panel. Allow 1‑7/16 inch (3.7cm) in front of the
mounting panel for knob clearance. Be sure to cut out
a ventilation hole in the mounting shelf according to
