Introduction
Performance Features
The McIntosh MP1100 Phono Preamplifier is one of
the finest Phono Preamplifiers ever created and has
the ability for connections to components with analog
and digital inputs. The MP1100 reproduction is soni-
cally transparent and absolutely accurate. The McIn-
tosh Sound is “The Sound of the Music Itself.”
• Electromagnetic Input Switching
Digital Logic Circuits drive Electromagnetic Switches
on Inputs and operating functions for reliable, noise-
less, distortion free switching.
• Vacuum Tube Phono Amplification
The MP1100 utilizes Vacuum Tube Amplification
Circuitry for the Phono Inputs. The circuits use the
latest designs providing the lowest possible noise and
distortion.
• Fully Balanced Circuitry
The MP1100 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.
• Moving Coil and Moving Magnet Phono Inputs
The MP1100 has three precision Phono Preamplifier
Circuits with unbalanced and balanced connections.
They have the ability to be configured for Moving
Coil or Moving Magnet Cartridges. The close toler-
ance resistors and capacitors used in the Equaliza-
tion Circuitry provide an extremely flat frequency
response.
• Selectable Phono Cartridge Loading
Adjustable Capacitance and Resistance Loading are
available for both Moving Coil and Moving Magnet
Phono Cartridges. Resistance Loading is selectable
from values of 25 ohms to 47,000 ohms. Capacitance
Loading is selectable from values of 50 picofarads to
400 picofarads.
• Balanced and Unbalanced Outputs
The Balanced Outputs allow connection using long
cable lengths without a loss in sound quality. The
MP1100 also has unbalanced Output connections for
compatibility with a wide range of audio components.
• Rumble and Scratch Filters
Selectable Rumble and Scratch Filters can improve the
quality of sound when playing back older vinyl recod-
ings.
• Digital Audio Outputs
The Digital Outputs encode PCM Signals from the
selected Input (Phono and Line). Coaxial and Optical
Outputs process Digital Signals at 96kHz or 192kHz
with 24-Bit resolution. The Digital Outputs have two
different output level settings and the Digital Circuitry
can be switched Off providing true analog only signal
processing.
• USB Digital Audio Output
The USB Digital Output provides Digital Signals at
96kHz or 192kHz with 24-Bit resolution from the
selected Input.
• Dual Mono Design
The circuitry for both channels is totally separate,
physically isolated and shielded which helps to assure
total channel isolation.
• Selectable Equalizer
In addition to normal RIAA Equalization Standard,
the MP1100 provides the ability to select four alterna-
tive Equalization Settings of LP, AES, NAB or 78.
This helps to assure a desired tonal balance when
playing a wide variety of phonograph records made
before the RIAA Equalization Standard was em-
ployed.
• Alphanumeric Fluorescent Display
The Front Panel Information Display indicates the
Source Selection, Cartridge Loading, Equalizer and
Setup Mode Selections. The display intensity is ad-
justable.
• Illuminated Output Meters
The Illuminated Output Meters are peak responding,
and indicate the output of the MP1100 Phono Pream-
plifier.
• Special Power Supply
The Multi Regulated Power Supply and a special
R-Core Power Transformer ensure stable noise free
operation even though the power line varies.
• Remote Control with External Sensor Input
The Remote Control provides control of the MP1100
operating functions. The External Sensor Input pro-
vides Remote Control when the MP1100 is located
behind closed doors or in another room.
