Mount the Loudspeaker
Refer to Figure 5.
1. Make sure all of the dog-ears are fully extended and in their
non-capture position.
2. Position the loudspeaker into the hole prepared in the ceiling.
3. Use a Phillips screwdriver to tighten each of the three dog-ear screws.
As you tighten the screws, the dog-ears will swing into capture position
over the ceiling. Be sure all dog-ears are properly positioned over the
ceiling.
4. Tighten the dog-ears until rm contact is made with the ceiling surface.
CAUTION: Do not overtighten the dog-ear screws! Insert
the grille saftey tether grommet into supplied hole on the
loudspeaker bae and install the grille.
Prepare Ceiling
Refer to Figure 1.
1. Use the template provided to mark and cut a hole (1) in the ceiling
where the loudspeaker is to be installed. For frame-construction
ceiling, skip to “Wire the Loudspeakers”.
2. Install two V-rails (2), one on each side of the hole, and supported by
the suspended-ceiling support rails (3).
3. Install the C-ring (4) over the hole, using the V-rails as support. Make
sure the clips on the C-ring are properly tted over the V-rail.
4. Use sheet-metal screws (5) to secure the C-ring to the V-rails.
Wire the Loudspeakers
1. Set the transformer tap switch located under the grille for the desired
wattage setting or 16Ω for low impedance operation as shown in Figure 2.
2. Back out the conduit covers Phillips retaining screw to its stop point and
pull the conduit cover straight out to remove as shown in Figure 3.
3. Pass the wires through the conduit/stress-relief clamp, leaving enough
wire for making connections. Carefully tighten the clamp over the wires,
or over the conduit if used.
4. Wire the female Euro-style plug as shown in Figure 4.
5. Plug the connector securely into the receptacle.
6. Reattach the conduit cover and secure with the Phillips retaining screw.
