Installation

Installation

The MC302 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 MC302 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 

MC302 is removed from the custom installation and 

used free standing. The required panel cutout, ventila-

tion cutout and unit dimensions are shown.

Always provide adequate ventilation for your MC302. 

Cool operation ensures the longest possible operating 

life for any electronic instrument. Do not install the 

MC302 directly above a heat generating component 

such as a high powered amplifier. If all the compo-

nents 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 oper-

ating temperature.

A custom cabinet installation should provide the fol-

lowing minimum spacing dimensions for cool opera-

tion.

Allow at least 6 inches (15.24cm) above the top, 2 

inches (5.08cm) below the bottom, 3 inches (7.62cm) 

behind the rear panel and 2 inches (5.08cm) on each 

side of the Power Amplifier, so that airflow is not 

obstructed. Allow 7/8 inch (2.22cm) in front of the 

mounting

1

 panel for clearance. 

Be sure to cut out a 

ventilation hole in the mounting shelf according to 

the dimensions in the drawing.

 When the MC302 is installed together with other McIn-

tosh Components, check clearances on all components 

before proceeding.
