Product Feature Identification
(Control 14C-VA Shown)
The 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. The 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 sheetrock (typically gypsum board) ceiling, JBL’s optional pre-installation brackets can be installed before the sheetrock is installed. The 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:
- The optional NEW-CONSTRUCTION BRACKET is made of %at sheet metal, 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. Sheetrock installs over the bracket, and the bracket provides a template for the blind cutout of the hole in the sheetrock. The sheetrock is typically cut with a router-type cutting tool, using the bracket ring as a cutout guide.
- The optional PLASTER-RING BRACKET (or “mud ring”) contains a circular set, forming an edge guide for sheet rock plastering. The bracket has wings that attach to the building structure. Sheetrock is typically either precut or cut with a rotary cutting tool using the outside of the plaster ring circle as a guide. The sheetrock hole is then plastered (or “mudded”) up to the ring to create a seamless cutout.

STEP-BY-STEP INSTALLATION AND WIRING
The installation system has been designed so that the entire installation can be accomplished from beneath the ceiling for instance 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.
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 in 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 through each tab into the rail. “is can all be accomplished from below the ceiling tile, if necessary.
IMPORTANT TO USE BRACKETS
ALL included support brackets – C-plate and tile rails — MUST be used when installing into suspended ceiling tiles.
Additional Suspended Ceiling Installation Information
Tile Rails: The tile rails are designed to !t either standard 24-inch wide tiles or 600-mm wide tiles. The tile rail pieces do NOT physically attach to the T-grid struts. Instead, the inverted-V shape at the ends of the rails sits 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: The 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 – The 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 Fitting is affxed 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).
Step 4 – Connect the Wiring to the Ceramic Terminal Block – The 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 the wire fully into the connector (not allowing any bare wire outside of the 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.
Figure 7: Connecting Wires to the Ceramic Terminal Block
(Note that the right-hand wire shown in the diagram is optional. It only needs to be connected if the chassis of the driver needs to be connected to safety ground.)
Figure 8: Connecting two sets of wires to the Ceramic Terminal Block for loop-out to a subsequent loudspeaker
Figure 9: Paralleling connections to multiple speakers for 70V or 100V distributed speakers systems
Guide to the Pins for Connection — The Ceramic Terminal Block contains 3 terminals, as marked on the connector as + INPUT, – INPUT, and 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 cover plate so that there is no strain on the wires inside the compartment).
Step 6 – Insert Speaker into Ceiling & Tighten– Insert the speaker into the ceiling as far as it goes, until the front ba(e rim touches the ceiling.
(C-ring/tile-rail assembly is above the ceiling tile. Speaker inserted through a cutout in ceiling material. The diagram shown without cable and ceiling tile for clarity) Turn the attachment screws to tighten the mounting tabs, by using the following directions:
IMPORTANT — For each attachment screw, FIRST turn ½ turn COUNTER-CLOCKWISE to release the mounting tab from its guide.
Then tighten the mounting tabs by turning the screw CLOCKWISE until tight. The first ¼ clockwise turn rotates the attach- ment 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 – The tap selector rotary switch is located on the front ba(e. 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 distributed system tap settings.
(Shown: Control 14C-VA. Tap ratings on the other models differ from the figures.)
Step 8 – Insert the Grille – A$er testing the speaker, consider which direction the logo is facing and press the grille into place until the front of the grille is %ush with the rim. It is o$en 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-certified loudspeakers.
For Non-EN54 Applications — The speaker’s textured white finish complements most decor and does not need further finishing. Where the interior design requires it, these speakers are easy to paint.
The rim can be painted before installation or in cases where the rim needs to be finished along with the ceiling, the speaker rim can be painted a$er attaching into the ceiling.
Type of Paint – The 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.
- • After 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 first. The 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 ba(e, paint the speaker, then remove the shield.
- Painting the Grille – Painting the grille requires the removal of the logo prior to painting (the logo should be stuck back onto the grille after painting, making sure it is located in the exact center of the grille).
- The 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 grill 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.
