Introduction and Performance Features
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 transpar-
ent and absolutely accurate. The McIntosh Sound is
“The Sound of the Music Itself.”
• 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 Electromag-
netic 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 qualit y.
• Precision Tracking Volume Control
Volume levels are controlled by a Precision Balanced
Digitally Controlled Attenuator System with an Opti-
cal 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.
• HXD
®
for Headphones
The C1100T Headphone Crossfeed Director Circuitry
(HXD
® )
improves the sound localization for Head-
phone Listening. HXD
TM
restores the directionality
component of the spatial sound stage normally heard
with Loudspeaker listening.
• Alphanumeric Fluorescent Display
The Front Panel Information Display indicates the
Source Selection, Volume/Balance Levels and Setup
Mode Selections. The display intensity is adjustable.
• PASSTHRU Mode
The Automatic PASSTHRU Mode allows the C1100T
to become part of a Home Theater Multichannel
Sound System.
• Remote Control with External Sensor Input
The Remote Control provides control of the C1100C
operating functions and McIntosh Source Components
connected to it. Enjoy your McIntosh System from
another room in your home by connecting an external
sensor.
• Power Control Output and Trigger Assignment
A Power Control connection for convenient Turn-On
of McIntosh Power Amplifiers, Source Components
and Accessories is included. The Power Control Trig-
ger Ouputs may be assigned to activate when a given
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 accom-
plished 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.
This will ensure the pristine beauty of the C1100 will
be retained for many years to come.
