Introduction

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.”

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.

• 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.
