INSTALLATION

allowing it to slide into the shelves. When the unit has been positioned completely into the

cabinet and its front panel is against the cabinet panel, it can be locked into position. Turn

each PANLOC button approximately one-quarter turn clockwise to lock. Turn the PANLOC button

one-quarter turn counterclockwise to unlock the unit so it can be removed from the cabinet.

UNPACKING

Open the carton and remove the PANLOC shelves, the hardware package and the mount-

ing template. Lift the amplifier up off the shipping pallet and remove the plastic bag. The

amplifier is now ready for shelf or table top installation.

If the amplifier is to be installed in a Mclntosh cabinet or custom installation, place it carefully

upside-down on a flat surface and unscrew the four plastic feet from the bottom of the amplifier

chassis.

INSTALLING IN A McINTOSH CABINET

Guide the amplifier AC power cord through the front panel opening to the back of the cabinet.

Slide the amplifier into the opening, making sure the rails on the bottom of each side of the

amplifier chassis engage the tracks on the PANLOC shelves. Slide the amplifier completely

into the cabinet until the back side of its front panel is pressing gently against the front of

the cabinet panel. Turn the PANLOC buttons approximately one-quarter turn clockwise to lock

the amplifier into the cabinet. Turn the buttons one-quarter turn counterclockwise to unlock

and remove the amplifier.

CUSTOM INSTALLATION

1. MARK THE CABINET FRONT PANEL

Tape the plastic mounting template to the cabinet panel in the position where the amplifier

is to be mounted. The broken lines that represent the outline of the rectangular cutout also
represent the outside dimensions of the amplifier chassis. Make sure these lines clear any
shelves, partitions or any other equipment mounted in the same cabinet. 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 a ruler or straightedge.

2. DRILL THE HOLES

Use a drill with a 3/16 inch (5mm) bit. Drill perpendicular to the front panel 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, be sure the six A and B holes have been drilled.
