Control 25AV-LS

Professional Compact Loudspeaker for

Life Safety Applications

JBL Professional Control 25AV-LS

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.

Coating the woofer cone in polypropylene and

terminating its circumference in JBL’sWeatherEdgeTM,

a seamless, butyl rubber extension of the woofer

surround, protects critical transducer elements. The

polycarbonate tweeter diaphragm is reinforced with a

thin ﬁlm of titanium for added rigidity and endurance.

Nickel/zinc rust-resistant terminals ensure a secure

input connection.

JBL’s exclusive SonicGuardTM overload protection is

virtually inaudible to the listener, ensuring reliability

while providing full ﬁdelity sound.

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.

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.

3. Remove the logo badge on the speaker grill by pulling it

straight out as shown in Fig. 3.

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.

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.

WIRING INSTRUCTIONS

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.

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

PAINTING THE CONTROL 25AV-LS

The polystyrene speaker enclosure of the Control 25AV-

LS 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.

The InvisiBall mount may also be painted, but because

it is metal, latex paints will not adhere as well as other

ﬁnishes.

MAINTENANCE

No maintenance is required when assembled in accordance

with the instructions and wiring guidelines described in this

manual. The cabinet on the Control 25AV-LS is designed

to be weather resistant but it is NOT WEATHERPROOF.
