Installation Preparations
e entire installation can be accomplished, if necessary, without requiring access above the ceiling. Bracketry for use with
either suspended ceilings or sheetrock ceilings is included. e
speaker is held securely in place via mounting ears which lock
into place.
OPTIONAL PRE-INSTALLATION BRACKETS
IN MOST CASES, NO BRACKETS OTHER THAN THE
ONES INCLUDED WITH YOUR SPEAKER ARE REQUIRED.
Everything needed for most installations of these loudspeakers
is provided with your Control Contractor ceiling speaker.
However, when the speaker is being installed into a sheet rock
(typically gypsum board) ceiling, JBL’s optional pre-installation
brackets can be installed before the sheetrock is installed. e
pre-installation bracket provides a bracket to which wiring can
be tied behind the sheetrock. It can function as a cutout template when many cutouts are to be made in a production-line
style installation, and it secures the ceiling speaker to the
building structure. Two types of pre-installation brackets are
available from JBL Professional as optional accessories:
1) e optional NEW-CONSTRUCTION BRACKET is made
of at sheetmetal, with wings to attach to the building structure.
Holes are drilled for nails or screws at 16 inches (406 mm) and
24 inches (610 mm) on-center. Additional holes can be drilled
by the installer at other spacings up to a maximum of 24-3/4
inches (630 mm) apart. Sheet rock installs over the bracket, and
the bracket provides a template for blind cutout of the hole in
the sheet rock. e sheet rock is typically cut with a router-type
cutting tool, using the bracket ring as a cutout guide.
Figure 1:
Optional NC New-Construction Bracket
2) e optional PLASTER-RING BRACKET (or “mud ring”)
contains a circular oset, forming a edge guide for sheet rock
plastering. e bracket has wings that attach to the building
structure. Sheet rock is typically either precut or cut with a
rotary cutting tool using the outside of the plaster ring circle as
a guide. e sheet rock hole is then plastered (or “mudded”) up
to the ring to create a seamless cutout.

STEP-BY-STEP
INSTALLATION AND WIRING
e installation system has been designed so that the entire
installation can be accomplished from beneath the ceiling for
instances when access above the tile is not possible or practical.
However, in some cases it may be easier with removable ceiling
tiles to access from both the top and bottom of the ceiling tile
during various phases of the installation.

Step 1 – Cut the Hole in the Ceiling Material. Cut-
out the circular hole to the cutout hole size listed above. Pull
the wiring through the cutout hole.
Figure 3:
Hole Cutout
Step 2 – Insert Backing Hardware rough the
Hole. Packaged with the speakers are two types of backing
hardware – a C-shaped backing-plate bracket and two tile rails.
Suspended Ceilings – Insert the C-plate through the hole
cut in the ceiling tile. Place the C-plate around the hole with
the tabs located as shown on Figure 4. Insert the tile rails
through the cut hole in the ceiling tile. Snap the two rails
into the two tabs in the C-plate and align the rails so that the
ends extend OVER the T-channel grid on the side of the tile.
Secure the rails onto the C-bracket tabs by inserting a screw
though each tab into the rail. is can all be accomplished
from below the ceiling tile, if necessary.
FOR SAFETY:
IMPORTANT TO USE BRACKETS
ALL included support brackets – C-plate and
tile rails -- MUST be used when installing into
suspended ceiling tiles.
Figure 4:

Additional Suspended Ceiling Installation
Information
Tile Rails: e tile rails are designed to t either standard
24-inch wide tiles or 600-mm wide tiles. e tile rail pieces do NOT physically attach to the T-grid struts. Instead,
the inverted-V shape at the ends of the rails sit OVER
the T-grid strut. During normal operation, the rails are
supported by the edge of the tile. If the tile were to come
out or fall apart, the ends of the support rails are designed
to catch onto the T-grid, providing secure support to hold
the loudspeaker assembly in place.
Vibration Reduction: Loudspeakers can generate substantial vibration which can cause buzzing of the ceiling
materials or structure. Depending on the character of the
ceiling tile and structure, the installer might need to place
neoprene or other dampening material under the tile rails
or the edges of the tiles to eliminate rattles.
Cutout Placement: e tile rails are pre-punched with
attachment holes along their length. Placement is not
limited to the center of the tile as is the case with many
other tile rail support systems.
Non-Suspended Ceiling Types – e C-bracket can be
optionally used by itself to shore up the ceiling material and
to spread out the clamping force from the tab clamps. Insert
the C-plate through the cut hole in the ceiling and place it on
the back side of the hole before inserting the speaker.
Step 3 -- Removing Terminal Cover. Loosen the 4
screws holding the Terminal Cover Plate (you do not have to
remove them), slide the plate to where the screws line up with
the larger end of the keyholes, and remove the Terminal Cover
Plate.

Make sure the gland nut tting is axed and tightened in the
proper knock-out location (add a second gland nut to the other
knock-out location if two glands nuts are desired). Slide the
wire through the gland nut (do not tighten the gland nut onto
the wire yet).
Figure 6:
Plate
Step 4 – Connect the Wiring to the Ceramic Terminal Block – e Ceramic Terminal Block is attached to
the speaker. Strip the insulation back about 5 mm (about 3/16
inch). Do NOT strip wires back any longer than this. Insert the
bare end of wire fully into the connector (not allowing any bare
wire outside of connector). Only utilize the side of the terminal
where there aren’t already wires connected.
Add a second set of wires in parallel to the same terminals if
a second wire is utilized for looping to another loudspeaker. Screw down the hold-down screw until tight using a small
phillips-type screwdriver. Tighten any unused screws to avoid
rattling from vibration.

Terminal Block
(Note that the right-hand wire shown
in diagram is optional. It only needs
to be connected if the chassis of the
driver needs to be connected to a safety
ground.)

Step 5 – Re-attach Terminal Cover Plate and
Tighten Gland Nut -- Slide the wire through the gland nut
until you can re-attach the Terminal Cover Plate. Install the
cover plate so that the screws go in through the keyholes, and
slide the plate so that the screws are back at the narrow-slot end
of the keyholes. Tighten the 4 screws. Tighten the gland nut
onto the wire (leaving enough slack inside the coverplate so that
there is no strain on the wires inside the compartment).

Step 6 – Insert Speaker into Ceiling & Tighten– In-
sert the speaker into the ceiling as far as it goes, until the front
bae rim touches the ceiling.
Figure 14:

Turn the attachment screws to tighten the mounting tabs, by
using the following directions:
Figure 15:
Tightening Mounting Tabs
IMPORTANT -- For each attachment screw, FIRST turn ½
turn COUNTER-CLOCKWISE to release the mounting tab
from its guide.
en tighten the mounting tabs by turning the screw CLOCKWISE until tight. e rst ¼ clockwise turn rotates the attachment tabs outward and the remaining turns tighten the tabs
down onto the back of the ceiling surface. DO NOT OVERTIGHTEN.

A tab is provided on the back of each speaker for connection
to an independent secondary support point. Some construction codes require using this secondary support point, which
requires connecting a support line to a separate secure support
point on the building structure. Consult construction codes in
your region.
IMPORTANT -- Control Contractor ceiling speakers can generate substantial vibration . Using the seismic tab as a secondary
support point is highly recommended in case the ceiling tile
or structure breaks. In some areas, using the seismic tab as a
secondary support point is required by code.
Step 7 Adjust Tap Selector – e tap selector rotary
switch is located on the front bae. Adjust the tap setting
before applying power to the speaker and before inserting the
grille. From the OFF position, turn the selector counter-clockwise to set to the 8Ω (low impedance) nominal setting (see
spec sheet for more precise impedance information) or turn the
selector clockwise to set to the various 70V and 100V distribut-
ed system tap settings.

Step 8 – Insert the Grille – Aer testing the speaker,
consider which direction the logo is facing and press the grille
into place until the front of the grille is ush with the rim. It is
oen easiest to press in various places around the perimeter of
the grille. Make sure grille is securely seated to prevent it from
vibrating loose and falling.
Removing the Grille -- e grille presents a tight t in order
to make sure that it won’t fall out, even with high vibrations
that can be produced by these speakers. If you need to
remove the grille, it is easiest to do so by inserting 2 pointed
objects (such as push pins) into 2 nearby holes in the grille,
presenting slow even pressure to pull down on the grille until
that section of the grille comes out approximately 6 mm (1/4
inch) . Work your way around the grille, loosening a section
at a time until the grille comes out.
Painting the Speaker
For EN54 Applications -- Painting is not allowed for EN54
applications, under the general requirements for EN54-certied
loudspeakers.
For Non-EN54 Applications -- e speaker’s textured white
nish complements most decor and does not need further n-
ishing. Where the interior design requires it, these speakers are
easy to paint.
e rim can be painted before installation or in cases where the
rim needs to be nished along with the ceiling, the speaker rim
can be painted aer attaching into the ceiling.
Type of Paint – e speaker’s ABS rim accepts almost any type
of latex or oil based paint. Two coats are recommended.
Painting Process – For best results, the following procedure is
recommended:
• Clean the rim and grille with a light solvent such as mineral
spirits by rubbing the item with a lightly dampened cloth. Do
not, however, use abrasives such as sandpaper or steel wool. Nor
should you use gasoline, kerosene, acetone, MEK, paint thinner,
harsh detergents or other chemicals. Use of these cleaners may
result in permanent damage to the enclosure.
• Aer cleaning, apply two or more thin coats of either latex
or oil-based paints. Latex paint will adhere best if an oil-based
primer is used rst. Application can be made by rolling, brushing or spraying.
Painting the Speaker Along With the Ceiling – Insert the clear
plastic paint shield into the front of the speaker to mask the
drivers and internal bae, paint the speaker, then remove the
shield.
Painting the Grille – Painting the grille requires removal of the
logo prior to painting (the logo should be stuck back onto the
grille aer painting, making sure it is located in the exact center
of the grille).
e backing to the grille is glued in place so that it can’t interfere
with the movement of the woofer cone. Leave the grille backing
in place. Spray the grille lightly using thinned paint. Make
sure the spray is light enough that when the grille is held up to
the light, you can still see light through the grille holes (which
means that sound can also get through). Spray only the front of
the grille, not the back. Rolling or brushing the paint is discouraged because the mesh and/or backing may become clogged
with paint and poor sound quality may result, however using a
very short-napped roller can be made to work.
