Installation and Wiring

See Figure 7 To lower a loudspeaker which is already clamped by the Gripple.

1. Insert the setting key into the small hole in the bottom of the Gripple, which

forces the internal locking wedges open, and then,

2. 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 pull 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.

Installation in Outside or Moisture-rich Environments

For extra weatherproofing, apply a small bead of silicon sealant

around the ridge on the loudspeaker body where the top will join it

(Figure 8, arrow A). Slide the loudspeaker cover into position so its four recessed

holes align with the four threaded fittings on the top of the loudspeaker

(arrow B). Then insert the four provided machine screws and fasten the cover.

Finally, press the split cover plug into place (arrow C). Also apply some silicon

sealant on the inside and outside surfaces of the split cover plug before

installing.

If you have purchased the optional PST-14 Decorative Plastic Tubing, this is an

appropriate time to install it.

Loudspeaker Tap Setting

To gain access to the tap switch (inset below), remove the loudspeaker grille by

lifting the strapping tape attached on either side of the grille. Once the grille is

off, remove the tape and set the tap switch to the appropriate tap setting.

CAUTION: Do NOT change the setting on the tap switch while the loudspeaker is

in use. Turn off the power amplifier before adjusting this switch.

The tap switch is located on the front baffle adjacent to the loudspeaker cone

(arrow and inset in Figure 9, arrow in Figure 10).

You can use a standard #2 or #3 Phillips or a medium slot-blade screwdriver

(not the one provided with the loudspeaker kit), or just press with 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 left side of the power tap control shown in the

close-up on Figure 9 are the power values for 100-volt connections, and on the

right side are the power values for 70-volt connections.

IMPORTANT: 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 terminals. Just

be sure there is no applied signal when you are actually changing the tap switch

setting. When the desired setting is confirmed, replace the grille.
