JBL 25AV-LS User Manual

Control 25AV-LS

Professional Compact Loudspeaker for

Life Safety Applications

PRODUCT OVERVIEW

The Control® 25AV-LS is built on the same platform
as our popular Control 25AV and is UL 1480 UUMW
Listed for use in fire alarm and/or emergency
communication systems. The Control® 25AV utilizes
a deep cabinet, high power components and complex
network to achieve extremely smooth high fidelity
performance from a compact 2-way loudspeaker.
Premium performance capability and even coverage
ensures excellent sound quality throughout the
listening area.

The top-quality transformer, with reduced saturation,
allows the loudspeaker to be used on either 70 volt or
100 volt distributed speaker lines, with similar fidelity
performance to the 8 ohm bypass position.

The patented InvisiBall® mounting method is simple
to install, aims easily, and provides a high degree
of theft deterrence. The cabinet accepts a variety
of paints to match any décor. Weather resistance is
maximized by utilizing an aluminum grille featuring
polyester powder coating.

INVISIBALL MOUNTING INSTRUCTIONS

Designed to be unobtrusive, offer theft deterrence,
and simplify the installers job, the patented InvisiBall
mounting system features a unique method for installing a
loudspeaker onto a wall or other flat surface.

Installing this Commercial Sound product must be
done in accordance with local building codes and
regulations. Consult with a licensed contractor or
professional engineer regarding any installation
in which the loudspeakers are mounted to a wall or
ceiling. For outdoor applications, be sure to use a
mounting support system which has sufficient wind
load strength in accordance with local building codes
and regulations. JBL Professional is not responsible
for damages resulting from the negligent installation
of any bracket or speaker.

1. Install the InvisiBall mounting bracket plate on the
mounting surface as shown in Fig. 1. Be sure to use

anchor hardware that is appropriate for the mounting
surface and that the mounting surface will adequately
support the loudspeaker assembly.

4. Insert the supplied hex key into the hole exposed by the

®

logo badge. Lightly push and slowly rotate the hex key until
you feel the key fall into place. Loosen the InvisiBall clamp
as shown in Fig. 4.

5. Mount the speaker on the InvisiBall as shown in Fig. 5.

Fig. 1

2. Using a wide-tipped, slotted screwdriver, remove the
plastic InvisiBall knock-out plug by pushing downward as
shown in Fig. 2. Remove any residual plastic around the
hole to ensure the ball assembly will fit into the hole.

Fig. 2

3. Remove the logo badge on the speaker grill by pulling it
straight out as shown in Fig. 3.

Fig. 5

6. Tighten the clamp just enough to hold the speaker while
it is positioned in its desired orientation. When the speaker
is in the desired direction, tighten the InvisiBall clamp as
shown in Fig. 6 and replace the logo badge.

CAUTION: DO NOT OVERTIGHTEN.

Control 25AV-LS Loudspeakers feature barrier strip
input connectors. When wiring Control 25AV-LS

loudspeakers, always use proper electrical wiring
practices in accordance with your local building
codes and regulations.

To wire the Control 25AV-LS, connect the positive lead
(+) from your power amplifier to the positive input on the
Control 25AV-LS and the negative lead (-) from your power
amplifier to the negative input on the Control 25AV-LS as
shown in Fig. 7.

Fig. 7

Before turning on the amplifier, make sure the speaker
tap switch is set to the proper selection. Sending a

70/100V feed to the Control 25AV-LS in its bypass
mode may result in permanent damage to the
loudspeaker.

DISTRIBUTED LINE SYSTEMS

The Control 25AV-LS includes a transformer for use on
70V / 100V distribution lines as shown in Fig. 8. Be sure
to use a line distribution amplifier when using the Control
25AV-LS units with the transformer tap settings.

As with conventional 8 ohm loudpseakers, simply connect
the amplifier’s “+”and “-” outputs directly to the red (+) and
black (-) input jacks on the back of the enclosure. Set the
transformer tap (located on the lower left rear side of the
cabinet) to the desired wattage.

The advantage of using a 70V / 100V distribution line is the
ability to connect multiple Control 25AV-LS loudspeakers
to one amplifier channel providing that all the speaker taps
do not add up to more than the amplifier channel’s power
rating.

A conservative rule-of-thumb is to try to keep the sum of
the speaker loads (watts) under 80% of the power amp
rating. (e.g. A 100 watt amplifier channel will then drive 10
speaker set to 7.5 watts each, i.e. 10 x 7.5 = 75 watts).

TROUBLESHOOTING

If there is no sound from your speakers:

• Make sure your power amplifier is on and the gain is set
above its minimum setting.

• Make sure there is a signal to your amplifier from your
mixer.

• Ensure all wires are connected and that none are cut or
frayed.

• If more than one pair of speakers is being used, check
the minimum impedance requirments of your amplifier
(overloading your amplifier may result in damage to your
amplifier).

If there is no sound from one of your speakers:

• Check the balance control on your mixer.

• Check the channel output gains of your amplifier.

• Ensure all wires are connected and that none are cut or
frayed.

If there is no (or weak) bass output or a poor stereo
image:

• Make sure the polarities (+ and -) of the speakers inputs
are properly connected

MAINTENENCE & CONTACTING JBL

PAINTING THE CONTROL 25AV-LS

The polystyrene speaker enclosure of the Control 25AV­LS can be painted to match almost any decor.

1. Remove the grille and mask the woofer, tweeter, &
ports on the front, and the wire terminals on the back,
being careful that no tape comes in direct contact with the
drivers.

2. Clean the enclosures with a light solvent such as
mineral spirits by rubbing the components with a lightly
dampened cloth. Do not, however, use abrasives such as
sandpaper or steel wool on the enclosures. 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 enclosures.

3. After cleaning, apply two or more thin coats of either
latex or oil-based paints. Latex paints will adhere better
if an oil-based primer is used first. Application can be by
rolling, brushing, or spraying. The grilles require masking
of the logo plug, then spray painting. If the grill is rolled or
brush painted, the mesh may become clogged with paint,
and poor sound quality may result.
