APPENDIX A
USING THE RAIN HOOD
(WEATHER-PROTECTED LOUDSPEAKERS)
If your 700-HP loudspeaker was ordered with optional
weather protection, a rain hood is installed. It is provided to
protect the loudspeaker’s electronics from direct exposure
to rainfall. Before using the 700-HP loudspeaker, open the
rain hood as described in the following procedure.
1. Pull the exterior Velcro straps off the hood to allow it to
open.
2. Lift the flap fully outward, and unfold the fabric of the
rain hood.
3. With your other hand, reach into the hood and free the
two PVC supports from their corner pockets in the outer
flap.
4. Fold both supports out and re-insert them into the two
pockets, shown in Figure A.1, in the lower corners of
the soft side flaps. This will hold the rain hood fully open
for use, which is necessary for proper cooling of the
700-HP loudspeaker’s electronics.

CAUTION:
When operating a weather-pro-
tected 700-HP loudspeaker be sure the rain
hood is fully open. Leaving the hood closed or par-
tially open will limit the airflow through the amplifier,
which could cause it to overheat and shut down.
REMOVING THE HP-2/700 AMPLIFIER
If you need to remove the amplifier from a 700-HP loud-
speaker, perform the following steps:
1. Using a #2 Phillips screwdriver, remove all eight screws
from the amplifier module. This will free the HP-2/700
electronics module from the cabinet (Figure A.3).

amplifier module
2. Carefully slide the amplifier module out of the cabinet
using care not to stress the cables.
3. Disconnect the 4-pin loudspeaker connector.
Replacing the HP-2/700 Amplifier
To replace the amplifier, do the following:
1. Gently slide the amplifier partially back into 700-HP and
connect the loudspeaker connector.
TIP:
Avoid pinching wires behind the fans;
if necessary, reach in and guide the wire(s)
toward you as you slide the amplifier into place.
2. Start all eight screws into the holes before tightening
them.
3. Once all eight screws are started, tighten them using a
#2 Phillips screwdriver.
4. Tighten the inner four screws first, then tighten the
remaining four corners.
CAUTION:
Never use power tools in high
torque settings to remove or replace the
stainless steel amplifier and/or rain hood screws on
the 700-HP loudspeaker.
