The MC2102 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 MC2102 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 MC2102 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 MC2102. Cool operation ensures the longest possible operating life for any electronic instrument. Do not install the MC2102 directly above a heat generating component such as a high powered amplifier. If the MC2102 is installed in a cabinet, a quiet running ventilation fan can be a definite asset in maintaining the coolest possible operating temperature.

A custom cabinet installation should provide the following minimum spacing dimensions for cool operation. Allow at least 12 inches (30.48cm) above the top, 2 inches (3.81cm) below the bottom and 3 inch (7.62cm) on each side of the amplifier, so that airflow is not obstructed. Allow 22 inches (55.88cm) depth behind the front panel. Allow

1 inch (2.54cm) 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.

Packing Instructions

In the event it is necessary to repack the equipment for shipment, the equipment must be packed exactly as described and shown below.

The MC2102 Vacuum Tubes must be removed from the Amplifier Tube Sockets and placed into the inside openings of the four layer foam packing material. The foam with the tubes located inside are placed into the Amplifier Tube Cover and secured to the Chassis. Failure to do this will result in damage to the Vacuum Tubes and possibly the MC2102.

Four 1/4 - 20 x 2-1/4 inch cap screws and flat washers must be used to fasten the unit securely to the Shipping Skid. This will ensure the proper equipment location in the Inner Carton. Failure to do this will result in shipping damage.

Use the original shipping carton and interior parts only if they are all in good serviceable condition. If a shipping carton or any of the interior part(s) are needed, please call or write Customer Service Department of McIntosh Laboratory. Please see the Part List for the correct part numbers.
