The versatile Preamplifier provides connections for various input sources and outputs to drive multiple Power Amplifiers. The C22 reproduction is sonically transparent and absolutely accurate. The McIntosh Sound is The Sound of the Music Itself. Performance Features Electromagentic Input Switching Digital Logic integrated circuits drive Electromagnetic Switches on all Inputs and operating functions for reliable, noiseless, distortion free switching. There is also a Record Monitor function for checking the progress of a recording. Moving Coil and Moving Magnet Phono Inputs The C22 contains two different precision Phono Preamplifier Circuits. One for low output Moving Coil Phono Cartridges with selectable resistance loading, the other is for Moving Magnet Cartridges with selectable capacitive loading. Both circuits use the latest designs to provide the lowest possible noise and distortion. The RIAA Equalization Circuitry utilizies close tolerance resistors and capacitors for an extremely flat frequency response. Balanced Inputs The Balanced Inputs allow the connection of a source component using long cable lengths without a loss in sound quality. Low Distortion Distortion levels of all types are less than 0.08%. Music is amplified with total transparency and accuracy. Tone Controls with Bypass The C22 allows for bypassing the Bass and Treble Tone Circuitry. 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 basic control of the C22 operating functions and any McIntosh Source Components connected to it. Power Control Output A Power Control connection for convenient Turn-On of McIntosh Power Amplifiers, Source Components and Accessories is included. Precision Parts Only the finest precision 1% tolerance resistors are used throughout. 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. Extruded Side Panels The sides of the C22 are extruded aluminum panels with a bead blast textured surface and a black anodized finish. Solid State Front Panel Illumination The Illumination of the Front Panel is accomplished by extra long life Light Emitting Diodes (LEDs). 4

6 Installation Installation The C22 can be placed upright on a table or shelf, standing on its four feet. It also can be custom installed in a piece of furniture or cabinet of your choice. The four feet may be removed from the bottom of the C22 when it is custom installed as outlined below. The four feet together with the mounting screws should be retained for possible future use if the C22 is removed from the custom installation and used free standing. The required panel cutout, ventilation cutout and unit dimensions are shown. Always provide adequate ventilation for your C22. Cool operation ensures the longest possible operating life for any electronic instrument. Do not install the C22 directly above a heat generating component such as a high powered amplifier. If all the components are installed in a single cabinet, a quiet running ventilation fan can be a definite asset in maintaining all the system components at the coolest possible operating temperature. A custom cabinet installation should provide the following minimum spacing dimensions for cool operation. Allow at least 6 inches (15.24cm) above the top, 2 inches (5.08cm) below the bottom and 1 inch (2.54cm) on each side of the Tube Preamplifier, so that airflow is not obstructed. Allow 19-1/2 inches (49.53cm) depth behind the front panel. Allow 1-1/8 inch (2.9cm) in front of the mounting panel for knob clearance. Be sure to cut out a ventilation hole in the mounting shelf according to the dimensions in the drawing.
