INSTALLATION
The MA230 can be installed in furniture
cabinets, custom built installations or pro-
fessional relay racks. If the unit is to be used
on a shelf or table top, it can be housed in an
attractive Mclntosh cabinet.
Allow sufficient cabinet space for air circu-
lation. Minimum internal cabinet dimensions
should be at least 16 inches wide, 14 inches
deep, and 6 inches high. The back of the
cabinet should be left as open as possible for
ventilation. Proper ventilation will insure your
amplifier a long and trouble-free life,
The MA230 installs conveniently from the
front of the cabinet into the panel cutout.
Two amplifier mounting brackets are pro-
vided for each side of the cabinet panel open-
ing so the MA230 can slide easily into posi-
tion. The mounting brackets are attached to
the cabinet panel by two mounting strips.
The mounting strips are attached to the back
of the cabinet panel on each side of the panel
cutout. With the screws supplied, front cabi-
net mounting panels up to one inch thickness
may be used. Two knurled screws placed into
the MA230 back panel, through the mounting
brackets, hold the unit firmly in place. Due to
the weight of the MA230, it is recommended
that the mounting brackets rest on a wooden
shelf in the cabinet for added support.
The design of the mounting template
allows the cutout to be located either from
the front or the back of the cabinet panel.
Since the MA230 should rest on a shelf, lo-
cate the cutout from the back of the panel.
1A. Position the MA230 mounting tem-
plate on the cabinet panel area to be cutout
for the installation.
1B. On the back of the cabinet panel,
scribe a vertical line through the exact center
of the cutout area.
Place the template against the back of the
panel. Match the template centerline with the
scribed cutout centerline. The bottom of the
template must rest on the shelf.
1C. On each side of the centerline of the
template there are two holes marked "C."
The smaller diameter hole is below the larger
diameter hole. These are the "LOCATING
HOLES." These holes are used to locate the
front panel of the MA230 with reference to
the shelf behind the cabinet panel. So that
the MA230 will rest on the cabinet shelf, fol-
low these instructions carefully.
Mark the back of the cabinet panel with a
pointed instrument through the two small
diameter "LOCATING C" holes. Drill these
two holes through the cabinet panel with a
3
/
16
" diameter drill. Be certain the drill is per-
pendicular to the panel.
Now position the template on the front of
the panel. Align the larger
3

" diameter
upper "LOCATING C" holes in the template
with the drilled holes in the cabinet panel.
2. Mark the "A" and " B " drill holes and
also the four corner cutouts in the template.
Join the corner markers. The edge of the
template can be used as a straight edge.
