Installation Installation The C15 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 required panel cutout, ventilation cutout and unit dimensions are shown. Always provide adequate ventilation for your C15. Cool operation ensures the longest possible operating life for any electronic instrument. Do not install the C15 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 1-1/2 inches (3. 8cm) above the unit so airflow is not obstructed. Allow 17-1/2 inches (44. 5cm) depth behind the mounting panel, which includes clearance for connectors. Allow 1-1/8 inches (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. 17-1/2" 444mm 17-1/16" 433. 4mm 1/4" 6mm Outline of Front Panel Edge of Cutout End Caps 3-9/16" 90. 0mm 3-1/16" 77. 8mm Panel Height 3 1/2" 88. 9mm 7/32" 5. 3mm Front View of the C15 custom installed (Front View) 3/16" 5. 1mm Support Shelf Bottom of Cutout and Top of Support Shelf Must Coincide Mounting Surface Mounting Bracket at Both Sides of the Rear Panel.
