Introduction
Performance Features
• Electromagentic Input Switching with Level Trim
Adjustment and Title Reassignment
Digital Logic integrated circuits drive Electromagnetic
Switches on all Inputs and operating functions for reliable,
noiseless, distortion free switching. All eight Inputs on the
C220 can be matched in level, so that there are no abrupt
changes in volume levels between the different Inputs.
There is also a Record Monitor function for checking the
progress of a recording. Any of the eight Inputs can have
their Input Title reassigned to match the sources in the
system.
• Balanced Inputs
The Balanced Inputs allow the connection of a source
component using long cable lengths without a loss in sound
quality.
• Precision Tracking Volume Control
Volume levels are controlled by a new Multi-Stage Preci
-
sion Digitally Controlled Attenuator System with a track-
ing accuracy of 0.1dB.
• Variable Rate Volume and Balance Control Selection
The C220 Tube Preamplifier’s Volume and Balance Con
-
trol Circuitry provides an ideal rate of change with control
rotation.
• Tone Control with Assignable Bypass
The Bass and Treble Control Circuit Elements can be re
-
moved from the Signal Path of any selected input.
• Alphanumeric Fluorescent Display
The Multifunction Front Panel Display indicates the
Source Selection, Volume and Balance Levels. Setup Mode
Selections and Adjustments are also displayed. The display
intensity is adjustable.
• Precision Parts
Only the finest precision 1% tolerance resistors are used
throughout.
The McIntosh C220 Tube Preamplifier is one of the finest
Tube Preamplifiers ever created. The versatile Preamplifier
provides connections for various input sources and outputs
to drive multiple Power Amplifiers. The C220 reproduc
-
tion is sonically transparent and absolutely accurate. The
McIntosh Sound is “The Sound of the Music Itself.”
Introduction and Performance Features
• Low Distortion
Distortion levels of all types are less than 0.08%. Music is
amplified with total transparency and accuracy.
• Moving Magnet Phono Input
There is a Precision Phono Preamplifier for Moving Mag
-
net Cartridges.
• Phono Tube Saver
When the Phono Input is selected to be Off in the Setup
Mode, the power going to the Tubes performing the Phono
Amplification is removed, thus extending the life of those
two tubes.
• Output Switching
Front panel Output Push-buttons control two Switched
Outputs that allow sending signals to two separate Power
Amplifiers.
• Remote Control
The Remote Control provides control of the C220 operat
-
ing functions and any McIntosh Source Components con-
nected to it.
• External Sensor Input
There are provisions for connecting External Sensors,
which allows for enjoyment of your McIntosh System from
other rooms in your home via the Remote Control.
• Power Control Output and Trigger Assignment
A Power Control connection for convenient Turn-On of
McIntosh Power Amplifiers, Source Components and Ac
-
cessories is included. Three of the Power Control Ouputs
may be assigned to activate when a given Input is selected.
• 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.
• Fiber Optic Solid State Front Panel Illumination
The even Illumination of the Front Panel is accomplished
by the combination of custom designed Fiber Optic Light
Diffusers and extra long life Light Emitting Diodes
(LEDs). The glass Front Panel ensures the pristine beauty
of the C220 will be retained for many years.
