Installation Guide

Once the loudspeaker is mounted correctly in
the ceiling, set the tap switch (inset above) to the
appropriate tap setting before any audio is passed
through the loudspeaker.
Do not change the setting on the
tap switch while the loudspeaker
is in use. It’s best to turn off the
power amplifier before adjusting
this switch.
If necessary, remove the loudspeaker grille to
gain access to the tap switch, which is located on
the front baffle adjacent to the loudspeaker cone
(red arrows and inset in Figure 9, yellow arrow
in Figure 10).
You can use a standard #2 or #3 Phillips or a me-
dium slot-blade screwdriver (not the one provid-
ed with the loudspeaker kit), or just press with

Loudspeaker Tap Setting
your thumb firmly, and twist to adjust the power
control dial on the front face of the loudspeaker
baffle. As shown in Figure 9, you can make any of
five different settings, although the dial has dual
calibrations so at first glance it appears to have
ten settings. The 8-ohm position is the same on
both sides and is for a low impedance connection.
On the lower-left side of the power tap control
shown in the close-up on Figure 8 are the power
values for 100-volt connections, and on the upper
right side are the power values for 70-volt con-
nections.
Note.
The letters NC mean “no-connect” but
they do not actually break a connection. DO
NOT USE this setting if you’re using a 100-
volt distribution scheme as the loudspeaker
may draw excessive power; it corresponds to
the highest power that can be drawn with a
70-volt source.
This control makes it very easy and fast to balance
an installation since there is no need to open the
loudspeakers and move wires to different termi-
nals. Just be sure there is no applied signal when
you are actually changing the tap switch setting.

Note
: It is best to begin with the loudspeaker lower
than the anticipated final height, and lift it into po-
sition. It can be lowered later by using the Gripple
Setting Key, as shown in Figure 7, but best practice
is to set the height primarily by raising the unit.

If you want extra weatherproofing, apply a
small bead of silicon sealant around the ridge
on the loudspeaker body where the top will
join it (Figure 8A). Slide the loudspeaker cover
into position so its four recessed holes align
with the four threaded fittings on the top of the
loudspeaker (Figure 8B). Then insert the four
provided machine screws and fasten the cover.
Finally, press the split cover plug into place
(Figure 8C), also using some silicon sealant as
may be necessary.
If you have purchased the optional PST-14 Deco-
rative Plastic Tubing, this is an appropriate time
to install it.

To lower a loudspeaker which is already clamped
by the Gripple, Refer to figure 7.

. Insert the setting key into the small hole in the
bottom of the Gripple, which forces the internal
locking wedges open, and then,

. Slide the cables to lower the loudspeaker.
Use this method first to create some extra slack
in the safety cable, then support the loudspeaker
with your hand as you play out the main support
cable, lowering the loudspeaker to the desired
height. Finally remove the setting key to lock the
loudspeaker in place, and re-tension the safety
cable by pulling the loose end until it is snug.
