McIntosh MA6500 Owner's Manual

Installation
The MA6500 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 MA6500 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 MA6500 is removed from the custom in-
stallation and used free standing. The required panel cutout,
ventilation cutout and
unit dimensions are
shown.
Always provide
adequate ventilation
for your MA6500.
Cool operation en-
sures the longest pos-
sible operating life
for any electronic in-
strument. Do not in-
stall the MA6500 di-
rectly above a heat
generating compo-
nent 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 compo-
nents 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
(3.81cm) below the
bottom and 1 inch
(2.54cm) on each
side of the amplifier,

mensions in the drawing.
