Installation
The D150 can be placed upright on a table or shelf,
standing on its four feet. It also can be custom in-
stalled in a piece of furniture or cabinet of your
choice. The four feet may be removed from the bottom
of the D150 when it is custom installed as outlined be-
low. The four feet together with the mounting screws
should be retained for possible future use if the D150
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 D150.
Cool operation ensures the longest possible operating
life for any electronic instrument. Do not install the
D150 directly above a heat generating component such
as a high powered amplifier. If all the components are
installed in a single cabinet, a quiet running ventila-
tion fan can be a definite asset in maintaining all the
system components at the coolest possible operating
temperature.
A custom cabinet installation should provide the
following minimum spacing dimensions for cool
operation.
Allow at least 2 inches (5.08cm) above the top, 2
inches (5.08cm) below the bottom and 1 inch (2.54cm)
on each side of the Preamplifier, so that airflow is not
obstructed. Allow 15 inches (38.1cm) depth behind the
front panel. Allow 1-7/16 inch (3.66cm) 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.
