Installation
Installation
The MC303 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 MC303 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 MC303 is
removed from the custom
installation and used free
standing. The required
panel cutout, ventilation
cutout and unit dimen-
sions are shown.
Always provide adequate
ventilation for your
MC303. Cool operation
ensures the longest pos-
sible operating life for any
electronic instrument. Do
not install the MC303 di-
rectly above a heat gener-
ating component such as a
high powered amplifier. If
all the components are in-
stalled in a single cabinet,
a quiet running ventila-
tion fan can be a definite
asset in maintaining all
the system components at
the coolest possible oper-
ating temperature.
A custom cabinet instal-
lation should provide the
following minimum spac-
ing 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 Power Amplifier, so
that airflow is not ob-
structed. Allow 19-1/2
inches (49.53cm) depth
behind the front panel.
Allow 1-5/8 inch (4.12cm)
in front of the mounting
panel

for clearance. Be
sure to cut out a ventilation hole in the mounting shelf ac-
cording to the dimensions in the drawing.

When the MC303 is installed together with other McIntosh
Components, check clearances on all components before
proceeding.
