INSTALLATION PROCEDURE
1. Mark for Position
Mark the cabinet panel where the instrument is
to be installed. The solid lines in Fig. 1 represent
the outline of the rectangular cutout to be made
and also represent the outside dimensions of the
chassis. Make sure to clear internal shelves, parti-
tions, or any equipment. The broken line repre-
sents the outside dimension of the panel.
2. Drill Holes
Using a drill bit slightly larger than the tip of
your saw blade, drill one hole at each of two dia-
gonally opposite corners. The holes should barely
touch the inside edge of the outline.
3. Saw Panel Cutout
Place the blade of the saw in one of the holes.
Sawing carefully on the inside of the lines, first
make the two long cuts and then the two short
cuts. After the rectangular opening has been cut
out, use a file to square the corners and smooth
any irregularities in the cut edges.
4. Shelf Installation
In the same way mark and saw the ventilation
cutout shown in Fig. 2. Also drill two ¼ " holes for
the mounting screws. Install the shelf to the
cabinet panel. It must be able to support the total
weight of the instrument.
5. Install Instrument
Guide the AC power cord through the panel
opening to the back of the cabinet; then, slide the
instrument into the opening until its front panel is
flush with the cabinet panel. Secure the amplifier
to the shelf with #10 wood screws of the proper
length.
½ " thick shelf—use 1" screws
¾" thick shelf—use 1¼ " screws
Do not use longer screws. They may penetrate
electronic components inside the chassis and
cause severe damage. The screw length must not
exceed the shelf thickness by more than ½ ".
INSTALLATION IN A 19 INCH RACK
The optional RMA7 RACK MOUNTING ADAPTERS
install on each end of the amplifier front panel. On
each side of the amplifier, three screws secure the
front panel bracket to the chassis. See Fig. 3.
Remove these three screws, place the RACK MOUN-
TING ADAPTER over the screw holes, and replace
the screws. The entire amplifier weight is transmit-
ted through the RACK MOUNTING ADAPTERS to the
rack. Additional support for the amplifier can be pro-
vided at the rear of the chassis as desired.
