manual tuning knob, B. use the SCAN up or down
touchbuttons, C. use the preset station touchbuttons
or, D. use the SEARCH which will preview the preset
stations for 5 seconds each.
The sound enhancing SPATIAL audio processor
provides

tions or AM stations, SPATIAL provides reduced
noise and retains a broad stereo-like sound.
High quality tape recordings of FM broadcasts can
be made without the interference that stereo transmissions can cause. Carefully designed suppression
circuits eliminate the potential for stereo carrier
noise when making "off the air" tape recordings.

INTRODUCTION 3
The trouble-free life of an electronic instrument is
greatly extended by providing sufficient ventilation to
prevent the build-up of high internal temperatures
that cause deterioration. Allow enough clearance so
that cool air can enter at the bottom of the cabinet
and be vented from the top. With adequate
ventilation the instrument can be mounted in any
position. The recommended minimum space for
installation is 15 inches (38.1 cm) deep, 17 inches
(43.2 cm) wide, and 6 inches (15.2 cm) high.
The MR 7083 may be installed in a Mclntosh
cabinet or custom installed in furniture of your
choice. Always provide adequate ventilation. Never
place it above heat generating components such as
high powered amplifiers. Provide 1½ inches (3 cm) of
space above the preamplifier so as not to interfere
with a cooling air flow.
CUSTOM INSTALLATION
The PANLOC system of installing equipment
conveniently and securely is a product of Mclntosh
research. The PANLOC buttons on the front panel
will lock the unit firmly in place when they are
turned approximately one quarter turn clockwise. A
counterclockwise turn of the PANLOC buttons
unlocks the chassis from its mounting.
To install the instrument in a Mclntosh cabinet,
follow the instructions that are enclosed with the
cabinet. For any other type of installation, follow
these instructions:
1. Unpack from Carton
Open the carton and remove the PANLOC brackets,
hardware package, and mounting template. Remove
the instrument from its plastic bag and place it
upside down on the shipping pallet. Unscrew the
four plastic feet from the bottom of the chassis.
2. Mark the Cabinet Panel
Tape the mounting template in position on the
cabinet panel where the instrument is to be
installed. The broken lines that represent the outline
of the rectangular cutout also represent the outside
dimensions of the chassis. Make sure these lines
clear shelves, partitions, or any equipment. With the
template in place, first mark the six A and B holes
and the four small holes that locate the corners of
the cutout. Then, join the four corner markings with
pencil lines, using the edge of the template as a
straightedge.
3. Drill Holes
Use a drill with a 3/16 inch (5 mm) bit held
perpendicular to the panel and drill the six A and B
holes. Then, using a drill bit slightly larger than the
tip of your saw blade, drill one hole at each of two
diagonally opposite corners. The holes should barely
touch the inside edge of the penciled outline. Before
taking the next step, make sure that the six A and B
holes have been drilled.
