Introduction and Performance Features
Introduction
The McIntosh C49 Audio Preamplifier is one of the
finest Preamplifiers ever created with connections for
both analog and digital sources. The C49 Outputs have
the ability to drive multiple Power Amplifiers. The
C49 reproduction is sonically transparent and absolutely accurate. The McIntosh Sound is “The Sound of
the Music Itself.”
Performance Features
• Electromagnetic Input Switching with Level Trim
Adjustment
Digital Logic Circuits drive Electromagnetic Switches
on all Inputs and operating functions for reliable,
noiseless, distortion free switching. The Analog Inputs
can be matched in level, preventing abrupt changes in
volume levels.
• Moving Coil and Moving Magnet Phono Inputs
The C49 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
provides an extremely flat frequency response.
• Digital Audio Inputs
The Digital Inputs decode PCM and DSD Signals
from external sources. Coaxial and Optical Inputs
process Digital Signals up to 192kHz with 24-Bit
resolution. The Digital MCT Input Circuitry directly
decodes SACD/CD signals from an external Transport component. The USB Input for streaming audio
processes Digital Signals up to 384kHz with 32Bit
resolution, decodes up to DSD256 Digital Signals and
DXD 24Bit with a sampling rate up to 384kHz.
4
• Balanced Inputs
The Balanced Inputs allow the connection of a source
component using long cable lengths without a loss in
sound quality.
• PASSTHRU Mode
The Automatic PASSTHRU Mode allows the C49 to
become part of a Home Theater Multichannel Sound
System.
• 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.
• Remote Control with External Sensor Input
The Remote Control provides control of the C49
operating functions and McIntosh Source Components
connected to it. Enjoy your McIntosh System from
another room in your home by connecting an external
sensor.
• Variable Rate Volume and Balance Controls
The C49 Preamplifier’s Volume and Balance Control
Circuitry provides an ideal rate of change with control
rotation.
• Tone Controls
The Bass and Treble Trim Controls provide up to
12dB of boost or cut. The C49 remembers the Bass
and Treble Setting for each input.
• HXD® for Headphones
The C49 Headphone Crossfeed Director Circuitry
(HXD® ) improves the sound localization for Headphone Listening. HXDTM restores the directionality
component of the spatial sound stage normally heard
with Loudspeaker listening.
• Power Control Output and Trigger Assignment

Installation
Installation
The C49 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 C49 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 C49
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 C49.
Cool operation ensures the longest possible operating
life for any electronic instrument. Do not install the
C49 directly above a heat generating component such
as a high powered amplifier. 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 2 inches (5.1cm) above the top, 2
inches (5.1cm) below the bottom and 1 inch (2.5cm)
on each side of the Preamplifier, so that airflow 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
the dimensions in the drawing.

The Sampling Rate and the Bit Rate are determined
by the original recording, the Application Output
Format (when available) and the McIntosh-HD Control
Panel Settings.
Figure 107
Note: In general, when the original music is recorded
at a higher Sampling Rate, the result is usually
more detail in the music. However, this higher
rate results in consuming larger amounts of storage space. The Sample Rate usually should be set
to match the Sample Rate of the music recording
being played back.
