JBL sound systems are used in some of the world’s most famous arenas, concert halls and clubs. In fact, JBL speakers are the premier choice for today’s hottest touring acts and artists. You just can’t make a more professional choice.

This User Guide contains important information that will help you get the most from your JBL EON loudspeakers so please take a moment to read it and be sure to keep it in a safe place for future reference.

Congratulations and thanks from all of us at JBL Professional. You have invested in the best portable performance system available.

PACKAGE CONTENTS

Your EON10 G2 system should include the following:

• User Guide

• 1 EON10 G2 speaker

• 1 10’ (3 m) IEC Power Cable

AGENCY APPROVALS AND CERTIFICATIONS

This EON G2 System complies with all International Safety Requirements for Mains Operated

Professional audio equipment under IEC65, and Electromagnetic compatibility, Radio interference,

Emissions and Immunity requirements.

BEFORE YOU BEGIN - IMPORTANT INFORMATION

Before using your EON10 G2 speaker system please review the following for important information on safety and protection of your investment in quality loudspeakers:

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. 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 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.

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

(see AVAILABLE ACCESSORIES).

• 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. Make sure to unplug the unit before cleaning. Use a damp rag with a general-purpose household detergent. For grease and marking tape residue, use a damp cloth with isopropyl alcohol or mineral spirits and wipe dry. Do not use powerful solvents like acetone,

MEK, lacquer thinner or 1,1,1-Trichloro-ethane (house hold cleaning fluid). These solvents will damage painted and co-polymer surfaces of your speakers.

• 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 electrical ly powered device can produce dangerous shock hazards when wet or exposed to moisture. Keep speakers out of extended or intense direct sunlight such as that encountered in permanent, outdoor installation. The driver suspension will prematurely dry out and finished surfaces will be degraded by longterm exposure to intense ultra-violet light.

Placement Precautions

For Stand Mounting your EON speakers include a 35mm receptacle cup to facilitate mounting on tripod stands. When using stands, be sure to observe the following precautions:

• EON speakers include a thumbscrew that can be tightened to lock 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 specification to be certain it is designed to support the weight of the speaker (see specifications). Observe all safety precautions specified by the stand manufacturer.

• Always verify that the stand is placed on a flat, level, and stable surface.

• Route cables so that performers, production crew, and audience will not trip over the cables pulling the speaker over.

• Be sure to fully extend the legs of tripod type stands.

• Position the stand so that the legs do not present a trip hazard.

• Do not attempt to place more than one speaker on a stand designed for a single speaker.

• Always be cautious in windy, outdoor conditions. It may be necessary to place additional weight

(e.g. sandbags) on the base of the stand to improve stability.

Floor and Table Top Application

The EON10 G2 generates considerable energy. When placed on a slippery surface such as polished wood or linoleum, the EON10 G2 may move due to its acoustical energy output. Precautions should be taken to ensure that the speaker does not fall off a stage or table on which it is placed. One solution is to place the speaker on a rubber mat.

Electrical Safety

All EON products are fitted with a detachable power cord (supplied) which connects to the AC mains and the back panel of the loudspeaker. The power cord has an IEC female connector on one end and a male mains connector on the other end. This cord is supplied specifically to accommodate the different worldwide safety and electrical code requirements. Depending on the electrical power standards in your area, the power cord may have a 3-pin type plug. Do not cut off or damage the grounding plug. Like any electrical appliance, your EON powered speakers should not be used in water or when wet.

Quick Start

1. Refer to the “Basic Sound Reinforcement System with Stage Monitors” diagram on page 12

2. Turn the INPUT 1 and INPUT 2 & 3 controls fully counter clockwise.

3. Set the MIC/LINE switch.

• If a microphone will be connected directly to INPUT 1, 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 1, set the MIC/LINE switch to the LINE position (disengaged). The MIC LED will not illuminate when power is turned on.

4. Plug the power cable into a properly grounded 3-wire AC power.

5. Plug the XLR cable from the mixer or microphone into the INPUT 1 connector.

6. Connect unbalanced sources (if used) to the INPUT 2 & 3 connector.

7. POWER UP PROCEDURE

First, switch on the power to the mixer, audio sources, or musical instruments that are feeding your EON10 G2.

• Next, turn on the power switch (the front panel power indicator will illuminate).

• Reverse this process when shutting down your system. This will avoid disturbing thumps from the speaker as sources power on/off.

8. SET VOLUME

• If you are using an audio-mixing console, refer to the manufacturer’s instructions to properly set gain structure

(see the “Gain Structure” section on page 16).

• Turn up your sources to the level that will be used in performance and talk, sing or play into the system.

• Bring the INPUT 1 control up (clockwise) until the desired volume has been reached. If you are using a micphone, turn the INPUT 1 control up slowly to avoid feedback.

• If you are using the INPUT 2 & 3 inputs, bring the INPUT 2 & 3 controls up to the desired volume.

9. CHECK THE PEAK LED - The PEAK indicator flashes when the loudspeaker’s on-board amplifiers are approaching maximum output. Occasional flashes are normal for very loud operation. However, if the PEAK LED stays illuminated, the sound will be distorted and it is an indication that more speakers or a lower performance volume may be required for your specific application.

Controls

INPUT 1

Adjusts the level of INPUT 1. Use this control to match the input sensitivity of the EON10 G2 to the output level of the mixer, microphone, or instrument connected to INPUT 1. It is a common misconception that this control changes the power of a system. Your EON10 G2 will produce its rated output power no matter where this control is set. The INPUT 1 control determines how much signal is required at the input in order to drive the system to full output.

INPUT 2 & 3

This control adjusts the level of the inputs connected to INPUT 2 & 3.

MIC LINE 1

Connectors

INPUT 1

This balanced input accepts a standard XLR (female) connector. A broad range of signals from microphones (-48 dBu to 0 dBu nominal), audio mixing consoles, and electronic musical instruments may be connected here. When using a single audio input to the speaker, this is the input to use. The sensitivity of this input is controlled by the MIC/LINE SWITCH and the INPUT 1 rotary control.

MIX LOOP

INPUT 2 & 3

This 1/4” jack can accommodate one or two channels of audio. When a two-channel source is connected by means of a TRS 1/4” plug, both channels are summed to mono. A single channel source may also be connected here with a standard 1/4” TS plug. This input is intended for use with audio devices including cassette tape, CD, MP3 players, computer sound-card outputs, electronic keyboards, and electric/acoustic musical instruments. The level of INPUTS 2 & 3 is controlled by the INPUT 2 & 3 rotary control. See the APPLICATION EXAMPLES and CABLES

AND CONNECTORS sections of this guide for details on how this input may be used.

OUT

This XLR (male) output connector works with the MIX/LOOP SWITCH (see below) to provide a method of sending audio from your EON10 G2.

Switches

MIC/LINE

The MIC/LINE switch effects only INPUT 1. It selects between two sensitivity ranges. This switch is used to match the input sensitivity of the EON10 G2 with the output level of the device connected to INPUT 1. Depressing the MIC/LINE switch selects MIC (most sensitive) and causes the MIC/LINE

LED to illuminate.

CAUTION: Before adjusting this switch, be certain to rotate the INPUT 1 control fully counter clockwise.

After the MIC/LINE switch has been adjusted, slowly rotate the INPUT 1 control clockwise until the desired volume has been reached.

• Use the MIC position (depressed) when a microphone is connected to INPUT 1.

• Use the LINE position (disengaged) when a line level source such as an audio mixing console, audio playback device, or electronic musical instrument is connected to INPUT 1.

MIX/LOOP

This switch selects the source of the signal for the OUT connector.

CAUTION: Before adjusting this switch, be certain to set the input level control of any equipment connected to this output to its minimum gain (least sensitive) setting.

• In the disengaged position, only the signal from the INPUT 1 connector is routed directly to the OUT connector.

Changing the other settings on the audio panel will not effect the OUT signal. The INPUT 2 & 3 inputs will not be present at the OUT connector. Use this setting when you want to feed multiple EON powered speakers the same signal.

• In the MIX position (depressed), a blend of all inputs to the speaker (INPUT 1 and 2 & 3) will be sent to the

OUT connector. Any changes to input level settings will affect the OUT signal. See the APPLICATION

EXAMPLES section for details on how this mode may be used.

Indicators

PEAK / SIGNAL

The PEAK / SIGNAL LED (Light Emitting Diode) is a two-color device. Red indicates that the system is approaching clipping. The threshold for this light is actually about 2 dB below clipping.

An occasional flicker of the red LED on the loudest peaks is acceptable. If this LED remains red for more than the duration of brief dynamic peaks, the system is being overdriven. Continuously over driving the system will result in unpleasant and fatiguing distortion and may lead to premature failure of your speaker system.

MIX LOOP

If the red LED illuminates excessively:

• Reduce INPUT 1 and INPUT 2 & 3.

• Reduce the output level of the mixer, musical instrument, or other source to the speaker.

VOLTAGE SELECTION AND FUSES

Changing Voltage

Your EON10 G2 will typically be set at the factory to accommodate the power mains voltage in your area. Before you set up your EON10 G2 for the first time it is a good idea to verify that the setting of the selector is appropriate for the power in your area. Directly above the power switch you will see a seal that indicates the factory setting for the voltage. If the voltage indicated is correct for your area, go ahead and power up your EON10 G2.

In the event that you do need to change the voltage selection:

• Make sure that the AC is disconnected from the speaker.

• Directly above the power switch on the speaker is a voltage selector. Peel off the factory-applied seal.

• Set the voltage selector switch to the 115V or 230V setting as required for your area.

• After having reconfirmed that the correct voltage is selected, connect the AC

(IEC connector) and power the unit up.

DO NOT UNDER ANY CIRCUMSTANCES OPERATE THE UNIT WITH THE WRONG

VOLTAGE SELECTED. DOING SO MAY RESULT IN SERIOUS DAMAGE TO YOUR

SPEAKER SYSTEM WHICH WILL NOT BE COVERED BY WARRANTY.

Fuse Replacement

The EON10 G2 has no user-serviceable fuses. Failure of fuses is most frequently a symptom of problems requiring service by a competent technician.

Application Examples

One Piece PA System

In this basic PA setup a dynamic microphone is connected to INPUT 1. The MIC / LINE switch would be set to the MIC position (depressed). Several examples illustrating possible uses for INPUT 2 & 3 are shown.

Acoustic Electric Guitar - The mono or stereo output of an electrified acoustic guitar can be connected directly to INPUT 2 & 3. If a stereo instrument and cable are used, the left and right channels will be combined into mono.

Electronic Keyboards - A pair of electronic keyboards are connected to INPUT 2 & 3 via an adapter cable

(see the section “Cables and Connectors”). Such a cable is available from pro-audio dealers and is commonly used as an “insert cable”.

Portable CD Player - A portable CD player may be connected to the EON10 G2 by means of a 1/4” TRS to Mini-Phone adapter. Again, the left and right channels will be combined into mono.

Reference

Gain Structure

Gain structure is the term we apply to adjusting the relative input sensitivity and output levels of components in an audio system. The objective of proper gain structure is to minimize noise on one extreme and to prevent clipping on the other. Proper gain structure will result in all components clipping at about the same time.

First, let’s clear up one common misconception. The input control on an amplifier or powered speaker does not determine how much power it will produce. A 100 watt amplifier (for example) can produce 100 watts no matter where the input level control is set. The input level control simply determines how much input voltage is required to drive the amp to full output. If the input level controls of an EON10 G2 are set too low (rotated too far counter-clockwise) the mixer will go into clipping before the speakers are driven to full output. If the input level controls of an EON10 G2 are set too high (rotated too far clockwise) the system will be noisy. With that in mind, here’s a procedure for setting up system gain structure that will get the best dynamic performance possible from your system.

Summary

• Adjust your mixer so that the loudest passages of your performance drive the mixer almost to its peak output.

• Set the MIC / LINE switch to the LINE position (unless a microphone is connected directly to the EON input).

Slowly bring up the INPUT 1 level control of the EON10 G2 until the desired performance volume is reached.

When used with a typical DJ or audio mixer, this will probably place the control around 10:00 o’clock.

Step by step instructions

1.

Begin with all level controls on your mixer and EON10 G2 speakers at minimum. Note that the EON10 G2 has a switch that selects “Mic” or “Line” sensitivity. The “Mic” position should be used only when a microphone is connected directly to the input.

2.

Bring the INPUT 1 level control on your EON10 G2s to approximately 9:00 o’clock. We’ll come back and make some final adjustments here later on.

Bring the output of any electronic source (CD player, drum machine, electronic keyboard, etc.) to its “nominal” position. This will usually be marked. If it isn’t, bring the control to about 2/3 of its maximum position. Make sure that any foot pedals or other volume controls are at the position they will be during the performance.

4.

At your mixer, bring the “Input Attenuator” (sometimes called “Gain” or “Sensitivity”) control up while playing the instrument or talking / singing into the microphone. Be sure that the level you’re playing at is the same as the actual performance level will be. Watch the channel “Clip” or “Overload” or “Peak” indicator. It should just flicker on the very loudest dynamic peaks.

5.

Now bring the channel fader up to its “nominal” position (see the mixer Owners Manual).

6.

Slowly bring the mixer master faders up to their nominal position. At this point, you should hear sound from the EON10

G2s. If the level is too high, trim back the INPUT 1 control on the EON10 G2s.

7.

Repeat steps 3 – 5 for all remaining channels.

8.

Check the meters on the mixer output. If you’re seeing peaks that drive the meters into clipping, trim back the channel faders and master faders slightly. Also be aware that actual performance levels tend to be higher than rehearsal and sound check levels so you may want to trim back the input sensitivity slightly.

9.

If an outboard processor such as a graphic EQ is used, it should be set to “unity gain” (see the processor’s

Owners Manual). Unity gain means that the signal level on the output is the same as the level at the input.

10. Now bring up the input control of your EON10 G2 speakers until the desired performance volume is reached. If clipping occurs before the desired volume is reached you need more speakers or a lower performance volume.

11. Listen to your mix and adjust to taste.

12. At this point, the maximum output of the mixing console should be capable of driving your EON10 G2s to full out put and you will have the lowest noise operation that your equipment is capable of delivering.

Connections - Balanced and Unbalanced

There are two basic types of audio system interconnections for very low to medium level audio signals: Balanced and unbalanced. Your EON10 G2 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 INPUT 2 and INPUT 3 connectors. These inputs are balanced but will accept unbalanced inputs without the need for any special adapters.

• Use an adapter or special cable (see the section “Cables and Connectors”).

Loudspeaker Placement and Mounting

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 of 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 on a delay is recommended.

Stand speakers upright for PA - Tilt the speakers back 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.
