Section 2: Precautions
Watch For These Symbols
The lightning flash with arrowhead symbol within
an equilateral triangle, is intended to alert the user
to the presence of uninsulated. “Dangerous Voltage”
within the products enclosure that may be of sufficient
magnitude to constitute a risk of electric shock to
persons. The exclamation point within an equilateral triangle is intended to alert the user to the presence of
important operating and maintenance (Servicing) instructions in the literature accompanying the product.
AC Power Requirements
Before plugging an EON® speaker into an outlet ensure that it is able to provide
the appropriate AC power. EON speaker systems have been designed to
automatically detect 115V or 230V AC mains voltage 50/60 Hz.
DO NOT UNDER ANY CIRCUMSTANCES OPERATE THE UNIT WITH AN AC POWER SUPPLY LESS THAN
100V OR GREATER THAN 240V. DOING SO MAY RESULT IN SERIOUS DAMAGE TO YOUR SPEAKER
SYSTEM WHICH WILL NOT BE COVERED BY WARRANTY.
A robust AC supply is necessary for maximum performance. If the supply is too weak the bass performance may
be affected and if it sags (drops) too much the system may self-mute to protect itself. As soon as the appropriate
AC supply is restored it will continue to operate. Plugging multiple systems into the same outlet and long
extension cord runs may affect the AC supply to the systems.
CAUTION
In compliance with safety agency criteria and proper system operation, it is critical that the system
installer observe all electrical safety practices at all times and provide proper earth grounding for all
AC Power connections.
EON® Power Amplifiers - Operating Temperature
The design of the EON amplifier is such that it is very energy efficient and as a result does not get really hot.
In the rare event that it does get too hot it will automatically shut down to protect itself. When its temperature
has returned to within its operating range it will turn back on. A condition under which this may occur is when the
system is operated in very high ambient temperatures and the heat sink on the rear of the enclosure is in direct
sunlight. Always ensure adequate cooling and appropriate shade.
Care and Maintenance
While your EON speakers are rugged and will provide years of service, some common sense care in handling
will prevent damage and preserve appearance.
• If your speakers will be frequently moved, consider a padded carrying bag.
• If your EON speakers have been subjected to prolonged exposure to extreme low temperatures, avoid
subjecting them to heavy mechanical shock and warm the speakers up by playing at a low volume for one
hour before playing at loud levels.
• Keep the exterior of the speaker enclosure clean. Clean only with a dry cloth.
• EON speakers are not intended for fixed installation in outdoor environments. Moisture can damage the
speaker cone and surround, cause corrosion of electrical contacts, and create an electrical shock hazard.
Protect your speakers from moisture. Avoid exposing the speakers to direct moisture. Any electrically
powered device can produce dangerous shock hazards when wet or exposed to moisture. Keep speakers
out of extended or intense direct sunlight. The driver’s integrity may be affected and finished surfaces will be
degraded by long-term exposure to intense ultra-violet (UV) light.
6
THIS APPARATUS CONTAINS POTENTIALLY LETHAL VOLTAGES. TO PREVENT ELECTRIC SHOCK OR
HAZARD, DO NOT REMOVE CHASSIS, INPUT MODULE OR AC INPUT COVERS. NO USER SERVICEABLE
PARTS INSIDE. REFER SERVICING TO QUALIFIED SERVICE PERSONNEL.
Mounting / Suspending EON® Speakers
EON speakers are designed for portable applications in which the speakers will be stacked directly on the floor,
stage, speaker stands, or a solid, stable platform. When placed on a smooth surface such as polished wood
or linoleum, the speakers may move due to acoustical energy output. Precautions should be taken to assure
that the speaker does not fall off the stage or table on which it is placed. Optional accessory items are available
from JBL Professional and after-market suppliers to facilitate suspension and wall /ceiling mounting of EON
speakers. Only those items recommended by JBL Professional should be used. When using these items, review
all enclosed documentation and carefully follow all instructions and safety precautions.
CAUTION: Suspension of EON® speakers should be done by qualified persons following safe rigging standards
and practices. Unsafe mounting or overhead suspension of any heavy load can result in serious injury and
equipment damage.
CAUTION: When suspending this product carefully follow JBL instructions and local ordinances. Do not attempt
to use unless you have read and understood all instructions including the JBL User’s Guide. Attachment of the
loudspeaker to a supporting structure should be referred to a qualified professional.
Stand Mounting Safety Precautions
EON series full range models include a 36 mm receptacle cup to allow mounting on tripod stands or on a pole
over subwoofers. When using stands or poles, be sure to observe the following precautions:
• EON speakers include a thumb-screw that must be tightened to secure the speaker to the tripod stand. Before
mounting the speaker on the stand, be sure to loosen the screw so that it doesn’t prevent the pole from fully
penetrating the socket.
• Check the stand or pole specification to be certain the device is designed to support the weight of the speaker.
Observe all safety precautions specified by the manufacturer.
• Always verify that the stand (or subwoofer/pole) is placed on a flat, level and stable surface and be sure to fully
extend the legs of tripod type stands. Position the stand so that the legs do not present a trip hazard.
• Route cables so that performers, production crew, and audience will not trip and topple the speakers over.
• Inspect the stand (or pole and associated hardware) before each use and do not use equipment with worn,
damaged or missing parts.
• Do not attempt to place more than one EON series speaker on a stand or pole.
• Always be cautious in windy, outdoor conditions. It may be necessary to place additional weight (i.e. sandbags)
on the base of the stand to improve stability. Avoid attaching banners or similar items to any part of a speaker
system. Such attachments could act as a sail and topple the system.
• Unless you are confident that you can handle the weight of the speaker, ask another person to help you get it
onto the tripod stand or pole.
Hearing Damage, Prolonged Exposure to Excessive SPL
EON series loudspeakers are easily capable of generating sound pressure levels (SPL) sufficient to cause
permanent hearing damage to performers, production crew and audience members. Caution should be taken
to avoid prolonged exposure to SPL in excess of 90 dB.

Section 3: Quick Start
Congratulations on your purchase of JBL Professional EON® Series loudspeakers! We know you are anxious to
get up and running as fast as possible, which is why you are reading this section. The following will help you get
set up as soon as possible.
Packaging Contents
Your EON510 system should include the following:
1 x EON510 speaker
1 x 10’(3m) IEC Power Cable
1 x User’s Guide
1. Refer to the Application Examples with EON510 in Section 6.
2. Turn the INPUT 1 & 2, and 3 controls fully counter-clockwise.
3. Set the MIC/LINE switch:
• If a microphone will be connected directly to INPUT 3, set the MIC/LINE switch to the
MIC position (depressed). The MIC LED will illuminate when power is turned on.
• If a mixer, CD player, cassette tape, or electronic musical instrument (the “source”) will be connected directly
to INPUT 3, set the MIC/LINE switch to the LINE position (disengaged).
4. Set the EQ control to the center position – Flat.
5. Plug the power cable into a properly grounded 3-wire AC power outlet.
6. Plug the XLR cable from the mixer or microphone into the INPUT 3 connector.
7. Connect other sources (if used) to the LINE 1 & 2 input connector.
8. POWER UP PROCEDURE
The main power switch is located on the input panel on the back of the enclosure. Always ensure that the
speaker system is the last thing you power up, and the first thing to turn off when operating your complete PA
system. If speaker systems are daisy chained together always turn off the last system in the chain first. Power
“on” is indicated by the illumination of the logo on the front of the enclosure and the power “on” LED.
• First, switch on the power to the mixer, audio sources, or musical instruments that are feeding your EON.
• Next, turn on the power switch.
• Reverse this process when shutting down your system.
9. SET VOLUME
• If you are using an audio mixing console, refer to the manufacturer’s instructions to properly set
gain structure.
• Turn up your sources to the level that will be used in performance and talk, sing or play into the system.
• Bring the INPUT 3 control up (clockwise) until the desired volume has been reached. If you are using a
microphone, turn the INPUT 3 control up slowly to avoid feedback.
• If you are using the INPUT 1 & 2 input, bring the INPUT 1 & 2 control up until the desired volume has been
reached.
10. CHECK THE LIMIT LED
The LIMIT indicator flashes when the loudspeaker’s on-board amplifiers are approaching maximum output.
Occasional flashes are normal for very loud operation. However, if the LIMIT LED stays illuminated, the sound
may be distorted and it is an indication that more speakers or a lower performance volume may be required
for your specific application.

Section 5: Loudspeaker Placement and Suspension
The following guidelines will help you achieve optimum sound wherever you use your EON® loudspeakers:
Raise the speakers as high as possible.
For best results try to get the high frequency horn at least 2 to 4 feet above the heads of the audience. If the
speakers are too low, the people in the back of the audience will not receive the best quality sound.
Place the speakers between the microphones and the audience.
Feedback occurs when the microphones pick up sound from the speakers and “feed” the sound back through
the sound system. If space is limited, point the speakers away from the microphones to reduce feedback.
Locate the speakers away from turntables.
Low-frequency feedback occurs when the output of the speaker is picked up by the tone arm of the turntable
and is re-amplified. A heavy, solid turntable base and shock mounting can also reduce this type of feedback in
DJ applications.
Use more speakers in large or highly reverberant spaces.
Spreading speakers throughout these spaces will produce much better sound than trying to compensate with
loudness level or equalization. For very long distances, the use of another set of speakers with time delay is
recommended.
Stand speakers upright for PA - Tilt the speakers back on the side for stage monitoring. Upright stance
provides even coverage over a wide area. EON speakers are also designed with two slanted positions for
stage monitoring applications.
15
Using the suspension points
CAUTION: Suspension of EON® speakers should be done by qualified persons following safe rigging standards
and practices. Unsafe mounting or overhead suspension of any heavy load can result in serious injury and
equipment damage.
CAUTION: When suspending this product carefully follow JBL instructions and local ordinances. Do not attempt
to use unless you have read and understood all instructions including the JBL User’s Guide. Attachment of the
loudspeaker to supporting structure should be referred to a qualified professional.
CAUTION: Do not suspend speaker from pull-back point.
Before suspending the system, inspect all components involved for cracks, deformations, corrosion and/or
missing or damaged parts that could reduce strength and safety of the installation.
1. Remove suspension point caps
2. Insert load rated shoulder eyebolt with spacer and tighten appropriately
Never suspend more than one EON system from its suspension points.

Section 7: Connection Types
There are two basic types of audio system interconnections for audio signals: Balanced and Unbalanced.
Your EON® can accept either type of input.
Balanced Lines
In audio, a balanced line is a three-conductor system in which the two signal wires carry an equal, but
opposite voltage with respect to the ground wire. The ground wire acts only as a shield and does not carry
any audio signal current. Outside interference (such as RFI - Radio Frequency Interference) is either
shielded from the internal signal conductor, or if it gets into the cable is cancelled out by the opposite signals
at the receiving end. Balanced connections are preferred for any longer cable runs.
Unbalanced Lines
Unbalanced cable is a two-wire system where the shield (ground wire) acts as one of the current carrying
signal conductors. The center conductor enclosed by the shield is commonly known as the “hot” conductor.
Unbalanced audio cables do not reject noise as well as balanced lines.
Unbalanced lines are typical in home hi-fi type systems and on the outputs of electronic musical
instruments. These work well if the distance between the components is short, the signal level is
relatively high and all of the electronics used in the system are plugged into the same AC service.
Unbalanced Sources to EON Powered Loudspeakers
If you need to connect your EON speakers to an unbalanced source you have two options:
• Use the LINE 1 and LINE 2 connectors. These inputs are balanced but will accept
unbalanced inputs without the need for any special adapters.
• Use an adapter or special cable

Section 10: Warranty Information
The JBL Limited Warranty on professional loudspeaker products (except for enclosures) remains in effect for
five years from the date of the first consumer purchase. JBL amplifiers are warranted for three years from the
date of original purchase. Enclosures and all other JBL products are warranted for two years from the date of
original purchase.
Who Is Protected By This Warranty?
Your JBL Warranty protects the original owner and all subsequent owners so long as: A.) Your JBL product
has been purchased in the Continental United States, Hawaii or Alaska. (This Warranty does not apply to JBL
products purchased elsewhere except for purchases by military outlets. Other purchasers should contact the
local JBL distributor for warranty information.); and B.) The original dated bill of sale is presented whenever
warranty service is required.
What Does The JBL Warranty Cover?
Except as specified below, your JBL Warranty covers all defects in material and workmanship. The following
are not covered: Damage caused by accident, misuse, abuse, product modification or neglect; damage
occurring during shipment; damage resulting from failure to follow instructions contained in your Instruction
Manual; damage resulting from the performance of repairs by someone not authorized by JBL; claims based
upon any misrepresentations by the seller; any JBL product on which the serial number has been defaced,
modified or removed.
Who Pays For What?
JBL will pay all labor and material expenses for all repairs covered by this warranty. Please be sure to save
the original shipping cartons because a charge will be made if replacement cartons are requested. Payment of
shipping charges is discussed in the next section of this warranty.

Department), 8500 Balboa Boulevard, PO. Box 2200, Northridge, California 91329 (818/893-8411). We may
direct you to an authorized JBL Service Agency or ask you to send your unit to the factory for repair. Either way,
