Installation

The MCD550 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 MCD550 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
MCD550 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
MCD550. Cool operation ensures the longest possible
operating life for any electronic instrument. Do not
install the MCD550 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 ventilation 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 (5.1cm) above the top, 2
inches (5.1cm) below the bottom and 1 inch (2.5cm) on

each side of the SACD/CD Player, so that airflow is

not obstructed. Allow 17 inches (43.2cm) depth behind
the front panel. Allow 1-1/8 inch (2.9cm) 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.

Note: Temporarily, connect the AC Power

Cord coming from the MCD550 into an
AC Power Strip with an On/Off Switch.
Position the AC Power Strip so the On/Off
Switch on the strip is in very close proxim­ity to the MCD550 Front Panel STOP Push­button (the MCD550 Remote Control STOP
Push-button will not work for resetting the

micro).

2. Rotate the Track Control Knob clockwise to the
NEXT Track and hold the position, then press and
hold in the STOP< Push-button while at the same
time switching On the AC Power Strip.
