Installation
The MR89 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 MR89 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 MR89
is removed from the custom installation and used free
standing. The required panel cutout, ventilation cutout
and unit dimensions are shown.
Always provide adequate ventilation for your MR89.
Cool operation ensures the longest possible operating
life for any electronic instrument. Do not install the
MR89 directly above a heat generating component such
as a high powered amplier. If all the components are
installed in a single cabinet, a quiet running ventila-
tion fan can be a denite asset in maintaining all the
system components at the coolest possible operating
temperature.
When the MR89 is placed free-standing on a at
surface, allow at least 2 inches (5.08cm) above the
top, 2 inches (5.08cm) below the bottom and 2 inches
(5.08cm) on each side of the Tuner, so airow is not
obstructed. Allow 19-1/2 inches (49.53cm) depth
behind the front panel. Allow 1-7/16 inch (3.66cm) in
front of the mounting panel for knob clearance.
A custom cabinet installation should provide the
minimum spacing dimensions for cool operation.
Allow at least 2 inches (5.08cm) above the top, 2 inches
(5.08cm) below the bottom and 2 inches (5.08cm) on
each side of the Tuner, so airow is not obstructed.
The Custom Cabinet should be open backed and at
least 12 inches (30.48cm) away from any surface such
as a wall. Be sure to cut out a ventilation hole in the
mounting shelf according to the dimensions in the
drawing. Allow 1-7/16 inch (3.66cm) in front of the
mounting panel for knob clearance.
