Introduction and Performance Features
The McIntosh D150 Digital Preamplifier is one of the
finest Preamplifiers ever created with connections for
digital sources. The D150 Outputs have the ability to
drive multiple components. The D150 reproduction
is sonically transparent and absolutely accurate. The
McIntosh Sound is “The Sound of the Music Itself.”
• Dual Function
Use the D150 as the Preamplifer together with McIn-
tosh Source Components and Power Amplifier to form
a complete Audio System. Connect the D150 to an
exisiting McIntosh Analog Audio System to provide
the latest in Digital-to-Analog Conversion from digital
audio sources.
• Electronic Input Switching
Electronic Input Switching on all Inputs provides reli-
able, noiseless, distortion free switching.
• Digital Audio Inputs
The D150 has Coaxial, Optical, DIN and USB Digital
Inputs to Decode PCM and DSD Signals from an ex-
ternal source. The Coaxial and Optical Inputs process
Digital Signals up to 192kHz with 24-Bit resolution.
The Digital DIN connection allows for streaming of
high bandwidth digital signals (DSD, PCM) directly
into the D150 from external sources. The USB Input
processes Digital Signals up to 192kHz with 32Bit
resolution, decodes DSD128 Digital Signals and DXD
24Bit with a sampling rate of 352.8 (or 384).
• Quad Balanced Digital to Analog Converter
The 8 channel 32-bit, 192kHz Digital to Analog
Converter is used in a Stereo Quad Balanced Mode,
assuring the music is reproduced with a wide dynamic
range and extremely low distortion, for both Disc and
external sources.
• Balanced Outputs
The Balanced Outputs allow the connection of long
cable lengths without a loss in sound quality.
• Precision Tracking Volume Control
Volume levels are controlled by a new Precision Digi-
tally Controlled Attenuator System with a tracking
accuracy of 0.5dB.
• Alphanumeric Fluorescent Display
The Front Panel Information Display indicates the
Source Selection, Sampling Frequency, Volume Level
and Setup Mode Selections. The display intensity is
adjustable.
• Remote Control with External Sensor Input
The Remote Control provides control of the D150
operating functions and allows enjoyment of your
McIntosh System from another room in your home by
connecting an external sensor.
• Power Control Input and Output
A Power Control connection for convenient Turn-On
of McIntosh Power Amplifiers, Source Components
and Accessories is included.
• Special Power Supply
Fully regulated Power Supplies and a special R-Core
Power Transformer ensure stable noise free operation
even though the power line varies.
• Gold Plated Connectors
The Input and Output Connectors contacts are gold
plated for superior corrosion resistance and high elec-
trical conductivity.
• Fiber Optic Solid State Front Panel Illumination
The even Illumination of the Front Panel is accom-
plished by the combination of custom designed Fiber
Optic Light Diffusers and extra long life Light Emit-
ting Diodes (LEDs).
• Glass Front Panel
The famous McIntosh Illuminated Glass Front Panel
ensures the pristine beauty of the D150 will be re-
tained for many years.
