Installation Procedure
1- Using the included C-ring or the dimensions provided, trace a cutout pattern onto
the ceiling surface.
2- Cut the mounting hole. Use a sharp tool to avoid stressing or cracking the mount-
ing surface.
3- Pull the wires through the hole.
4- Pass the two suspended ceiling support brackets through the hole and place as
shown in the illustration. Make sure the part of the bracket that is flat against the tile
is toward the hole. If installing in a non-suspended ceiling application, these brackets
are not required.
5- Pass the C-ring bracket through the hole. Slide the cutout slot into the hole first,
EN
and then rotate the bracket so it passes through the hole. Be sure the wires pass
through the ring.
6- Position the support brackets, and secure the C-ring bracket to each of the support
brackets using the screws provided. If installing in a non-suspended ceiling applica-
tion, skip this step.
7- Loosen the connection cover plate retaining screw and swing the cover open.
Install an appropriate non-metallic sheathed cable connector into the hole provided
on the cover plate.
8- Temporarily support the enclosure so the wires may be passed through the enclo-
sure top with enough slack to prepare and terminate the wires.
9- Locate the terminal block connectors included with the loudspeaker. Loosen the
wire retaining screws fully.
10- Strip the wire ends approximately 5 mm (0.2") and insert each wire into its proper
connector position. Tighten the wire retaining screws fully.
11- Rotate the connection cover plate closed, making sure not to stress the connec-
tions or pinch the wires. Tighten the cover plate's retaining screw.
12- Adjust the wiring at the entry point, if necessary, and tighten the clamping
screw(s) on the non-metallic sheathed cable connector. This prevents wire stress and
strain from pulling the connections/connectors loose.
13- Attach a safety cable (secondary support cable) from the enclosure's attachment
tab to an appropriate support point. This cable and the attachment points must be
strong enough to support many times the weight of the loudspeaker in the event the
primary mounting system fails.
14- Insert the enclosure into the ceiling cutout, making sure any brackets used
remain properly positioned. Tighten the loudspeaker's mounting clamp screws.
15- Set the tap selector switch to the desired position. 70V systems, all four posi-
tions may be used. Do not use highest tap setting with 100V systems. 8 ohm sys-
tems, se selector to 8 ohm position.
16- Make sure all tests and adjustments are complete before installing the grills.
Locate the loudspeaker's grill. The cabinet and the grill both have a small loop of
plastic line. Using the clip on the grill's line, attach the grill's safety loop to the cabi-
net's loop. Carefully work the grill into its retaining slot and press firmly into place.
Work the grill in slowly and evenly to avoid damage. Make sure all tests and adjust-
ments are complete before installing the grills.
