Introduction

The McIntosh D1100 Digital Preamplifier is one of the
finest Preamplifiers ever created with connections for
digital sources. The D1100 Outputs have the ability to
drive multiple Power Amplifiers. The D1100 reproduc-
tion is sonically transparent and absolutely accurate.
The McIntosh Sound is "The Sound of the Music
Itself."

Performance Features

• Electromagnetic Output Switching
Digital Logic Circuits drive Electromagnetic Switches
for the Balance and Unbalanced Outputs 1 and Out-
puts 2 for reliable, noiseless, distortion free switching.
• Digital Audio Inputs
The Digital Inputs decode PCM and DSD Signals
from external sources. Coaxial, Optical, BNC and
AES/EBU Inputs process Digital Signals up to
192kHz with 24-Bit resolution. The Digital MCT In-
put Circuitry directly decodes SACD/CD signals from
an external Transport component. The USB Input
for streaming audio processes Digital Signals up to
384kHz with 32-Bit resolution, decodes up to DSD256
Digital Signals and DXD 24-Bit with a sampling rate
up to 384kHz.
• Dual Operating Modes
The D1100 has two modes of operation. One mode is
as a high performance full function Digital Pream-
plifier. The second mode is as a high performance
Digital to Analog Converter (DAC) which integrates
with an Analog only Preamplifier via a special Digital
Control Interface.

• 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 D1100 Preamplifier's Volume and Balance Con-
trol Circuitry provides an ideal rate of change with
control rotation.
• HXD for Headphones

phone Listening. HXD restores the directionality
TM
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.
• Remote Control with External Sensor Input
The Remote Control provides control of the D1100
operating functions and McIntosh Source Components
connected to it. Enjoy your McIntosh System from
another room in your home by connecting an external
sensor.
Introduction and Performance Features
• 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
