The MA2275 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 MA2275 when it
is custom installed as out-
lined below. The four feet
together with the mounting
screws should be retained
for possible future use if the
MA2275 is removed from
the custom installation and
used free standing. Install
the four supplied chassis
spacers into the threaded
openings on the bottom lo-
cated next to the just re-
moved four feet. The re-
quired panel cutout, ventila-
tion cutout and unit dimen-
sions are shown.
Always provide ad-
equate ventilation for your
MA2275. Cool operation
ensures the longest possible
operating life for any elec-
tronic instrument. Do not
install the MA2275 directly
above a heat generating
component such as a high
powered amplifier. If the
MA2275 is installed in a
cabinet, a quiet running
ventilation fan can be a
definite asset in maintain-
ing the coolest possible op-
erating temperature.
A custom cabinet instal-
lation should provide the
following minimum spac-
ing dimensions for cool op-
eration. Allow at least 12
inches (30.48cm) above the
top, 2 inches (5.08cm) be-
low the bottom and 3
inches (7.62cm) on each
side of the amplifier, so that
airflow is not obstructed.
Allow 20 inches (50.8cm)
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.
