Refer to the diagrams for connections: PIN 1: Shield/Ground PIN 2: + Signal PIN 3: - Signal PIN 1 PIN 2 PIN 2 PIN 1 PIN 3 PIN 3 The McIntosh C22 Stereophonic 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 C22 reproduction is sonically transparent and absolutely accurate. The McIntosh Sound is "The Sound of the Music Itself. " · 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 with External Sensor Input The Remote Control provides basic control of the C22 operating functions and any McIntosh Source Components connected to it. Enjoy your McIntosh System from another room in your home by connecting external sensors. · 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. 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. 17-1/16" 43. 34cm Opening for Ventilation C22 Front Panel Custom Cabinet Cutout 27. 62cm 10-7/8" Cabinet Front Panel Cabinet Front Panel Opening for Ventilation 15. 24cm 6" Cutout Opening for Custom Mounting C22 Side View in Custom Cabinet Cutout Opening for Ventilation Support Shelf 1-1/16" 2. 70cm Chassis Spacers C22 Bottom View in Custom Cabinet 2. 54cm 1" 21. 91cm 39. 37cm Cutout Opening for Ventilation 8-5/8" 15-1/2" 15-1/16" 38. 26cm 7. 62cm Note: Center the cutout Horizontally on the unit.
