Attach Grille Safety Cable
Note: Some codes now require that the grille have a safety cable. Your local
codes may vary. Community makes it easy to comply with an included security
cable system, as detailed below.
1. Once the loudspeaker is secured in the back can, you can attach the safety
cable between the grille and loudspeaker. There is a nylon mono filament
loop attached to the grille and looped through a metal clip. Another
mono filament line is located inside the bass reflex port of the face of the
loudspeaker. Use the metal clip to link these two mono filament loops
(Figure 12).
2. Carefully lower the grille until the cable holds it, and let go. It should hang
harmlessly from the mono filament line.
3. If you're proceeding with setup, you can leave the grille hanging so you can
adjust the power setting as noted below. Otherwise, snap the grille into
position on the face of the loudspeaker baffle.
Loudspeaker Tap Setting
Use a standard #2 or #3 Phillips or a medium slot-blade screwdriver (not the
one provided with the loudspeaker kit), or just press thumb firmly, and twist
to adjust the power control dial on the front face of the loudspeaker baffle. As
shown below, 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 in Figure 13
are the power values for 100V connections, and on the upper right side are the
power values for 70V connections.
Caution: Set the tap control initially prior to applying audio, and only change the dial
setting while the audio amplifier is shut off.
This control makes it very easy and fast to balance an installation since there
is no need to drop the loudspeakers out of their back cans and move wires to
different terminals.

attached.
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 100V distribution scheme as the
loudspeaker may draw excessive
power; it corresponds to the highest
power that can be drawn with a 70V
source.
