Painting The Speaker - JBL Control 12C-VA Owner's Manual & Installation Manual

A tab is provided on the back of each speaker for connection
to an independent secondary support point. Some construc-
tion 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 gen-
erate 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 –
switch is located on the front baffle. Adjust the tap setting
before applying power to the speaker and before inserting the
grille. From the OFF position, turn the selector counter-clock-
wise 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 –
consider which direction the logo is facing and press the grille
into place until the front of the grille is flush with the rim. It is
often 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 -- The grille presents a tight fit 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 fin-
ishing. 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 after 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. Application can be made by rolling, brush-
ing 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 baffle, 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 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 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 discour-
aged 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.
