The PRX700 series speakers covered by this manual are not intended for use in high moisture environments. Moisture can damage the speaker cone and surround and cause corrosion of electrical contacts and metal parts. Avoid exposing the speakers to direct moisture. Keep speakers out of extended or intense direct sunlight. The driver suspension will prematurely dry out and finished surfaces may be degraded by long-term exposure to intense ultra-violet (UV) light. PRX700 series speakers can generate considerable energy. When placed on a slippery surface such as polished wood or linoleum, the speaker may move due to its acoustical energy output. Precautions should be taken to assure that the speaker does not fall off a stage or table on which it is placed.

Stand Mounting Safety Precautions
Some PRX700 series 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:

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 PRX700 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.
JBL highly recommends that no more than 80 lbs of weight be placed on a speaker pole that is
mounted to a PRX715XLF or PRX718XLF.

General Hardware Information
Any hardware used in an overhead suspension application must be load rated for the intended use. Generally, this type of hardware is available from rigging supply houses, industrial supply catalogs and specialized rigging distributors. Local hardware stores do not usually stock these products. Hardware that is intended for overhead suspension will comply with ASME B30.20 and will be manufactured under product traceability controls. Compliant hardware will be referenced with a working load limit (WLL) and a traceability code.

Attachment to Structures
A licensed Professional Engineer must approve the placement and method of attachment to the structure prior to the installation of any overhead object. The following performance standards should be provided to the Professional Engineer for design purposes; Uniform Building Code as applicable, Municipal Building Code
as applicable, and Seismic Code as applicable.
The installation of the hardware and method of attachment must be carried out in the manner specified by
the Professional Engineer. Improper installation may result in damage, injury or death.

Inspection & Maintenance
Suspension systems are comprised of mechanical devices and, as such, they require regular inspection and routine maintenance to insure proper function ability. JBL suspend able loudspeakers must be inspected for fatigue at least annually or, if there has been significant seismic activity, immediately thereafter. The inspection shall include a visual survey of all corners and load bearing surfaces for signs of cracking, water damage,
de-lamination, or any other condition that may decrease the strength of the loudspeaker enclosure. Accessory suspension hardware provided with or for the JBL loudspeakers must be inspected for fatigue at least annually. The inspection shall include a visual survey of the material for signs of corrosion, bending or any other condition that may decrease the strength of the fastener. Additionally, any eyebolts shall be checked for possible spin- out of the enclosure.
For all other hardware and fittings, refer to the hardware manufacturer’s inspection and maintenance guidelines for process.

The PRX700 Series Power Amplifier

AC Power Requirements
Standard PRX700 series speaker systems are equipped with a multi-channel Class-D power amplifier
and loudspeaker specific DSP electronics and require appropriate AC power. Before plugging a PRX700 speaker into an outlet ensure that it is able to provide the appropriate AC power as required by the speaker.
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.

Powering Up
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 blue LED on the front of the enclosure.

Operating Temperature
The design of the 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 or the rear of the enclosure is in direct sunlight. Always ensure adequate cooling and appropriate shade.

Introduction to the PRX700 Series

JBL-PRX700-Series-PRX715XLF-Powered-15-Inch
Subwoofe-01

Thank you for choosing the JBL PRX700 series self-powered PA loudspeakers. The PRX700 Series represent an evolutionary step in the efficient use of amplifier power, rugged durability and enhanced versatility in a self powered loudspeaker. The speakers were designed from the ground up to perform in the real world of sound reinforcement where challenging audio environments, high ambient noise levels and loud volumes are the norm. And we’ve built these speakers to last a lifetime using tour tested technology that’s reliable and trustworthy. Knowing you can rely on your system to deliver everything you need gives you the freedom to deliver your best. That’s performance you can trust. With the PRX700 Series, as always, JBL delivers with precision and care. Properly maintained, your PRX700 series speaker will provide you with many years of flawless performance. To ensure you are always receiving optimum performance we encourage you to review this user’s guide completely before hooking up your new system.

The PRX700 Series is a platform technology that allows you to create the system you need from an intelligent range of models. While each model was designed to excel at a specific application, the PRX Series integrate seamlessly with one another offering a multitude of choices when tailoring a system to fit your specific needs. Whether you need a single speaker on a stand for public address situations, a full-range stereo set up with two top cabinets and a sub-woofer for live performance or DJ applications, or multiple cabinets for a scalable, highly professional sound reinforcement situation, the PRX700 Series offers the solutions. In fact, you can even suspend any of the top cabinets for use in a commercial installation or House of Worship. If versatility, scalability, portability and affordability are what you’re looking for in a system, PRX700s are the intelligent choice.

Road Tough
All PRX700 cabinets are built from a combination of 25mm (on the top and bottom for added rigidity) and 18mm, strong, lightweight poplar plywood made structurally sound with tongue and groove joints. All PRX700 Series cabinets are protected by JBL’s tour proven DuraFlex™ finish. We make our grilles from dent-resistant 16 gauge steel and our handles are made from lightweight glass- filled nylon for added durability. All M10 suspension points are constructed from 14 gauge steel and the M10 suspension points have been tested with a yield-strength of 1000 lbs. each.

Differential Drive Transducers
Extended frequency response, high power output and low distortion are hallmarks of all JBL transducers. Our tour tested, tour proven and patented Differential Drive® technology delivers all this performance in a dramati- cally lighter package than traditional transducer designs.

Powered Speaker Systems

A Closed System Architecture…
There is much confusion these days in the world of powered speakers especially when it comes to defining
“performance”. What constitutes “exceptional performance”? Is it wattage ratings, driver dimensions, cabinet dimensions, sound pressure levels, tone? It can get very confusing when you’re confronted with a barrage of specifications from manufacturers all claiming to have the “best performance”. A self powered speaker is really a “system” unto itself – it’s a “closed system”. Unlike a passive speaker, amplifier and signal processing chain where components can be interchanged or upgraded, the powered speaker is a “closed system” that operates as a single unit. Properly designed, all of the components are chosen to work together, complementing each other to create an environment where the whole is greater than the sum of the parts. The cabinet volume needs to support the mechanical performance of the speaker which is impacted by the power amplifier’s performance which, if there is Digital Signal Processing on the input, is affected by the DSP programming. Some manufactur-ers simply stick an amplifier on an existing speaker cabinet and call it a “powered speaker” (technically correct) while more experienced companies, like JBL, spend hundreds of man hours optimizing the relationship between the components in order to maximize amplifier and speaker efficiency, spectral balance, tone and dependability. Here at JBL we not only work hard on the system but on our proprietary components as well. Products like Dif- ferential Drive® speakers for example are patented designs born from years of dedicated research and develop-ment into acoustical and transducer science. No one else has access to this technology and Differential Drive® speakers have been tested on worldwide concert tours for years.

FEATURES

Selectable System EQ
- Normal and Boost (PRX710, PRX725, & PRX735 only) – When set in the “Normal” position, frequency response is linear and unaltered. When “Boost” is selected, internal equalization is applied to enhance low frequency and high frequency response. “Normal” will provide greater accuracy of reproduced music and higher speech intelligibility. “Boost” is particularly useful at lower levels to enhance the low and high frequencies of pre-recorded music. This feature provides flexibility without the need to use an
  external equalizer. The LED will illuminate GREEN when NORMAL is selected and YELLOW when BOOST is selected.
- Main and Monitor (PRX712 & PRX715 only) – Switching between “Main” and “Monitor” optimizes the system for use as either a main full-range system or a stage monitor. The LED will illuminate GREEN when MAIN is selected and YELLOW when MONITOR is selected.
PWR/STBY LED – This LED illuminates when the “Power Switch” has been turned to the on position. It will illuminate BLUE when the system has power and is ready to pass audio. It will illuminate RED when the system is in power save mode and not passing audio.
FRONT LED – This push button allows you to turn on/off the Power LED on the front of the speaker. The front LED will illuminate BLUE when the system has power and is ready to pass audio. When the front LED turn RED that means the system is in power save mode and not passing audio.
SIGNAL Indicator – There are two LED indicators (one for each channel) that will illuminate GREEN when signal is present at the input connector.
LIMIT Indicator – There is one YELLOW LED indicator that will illuminate when peak output has been reached and the DSP limiter is acting.
GAIN Knobs – This gain knob is for setting the input level of CH1 and CH2.
MIC/LINE Button – This push button allows you to choose between MIC or LINE level on CH1 only. CH2 is always line level.
GROUND LIFT Button – This push button allows you to lift the ground on CH2 only reducing unwanted hum and buzz caused by ground loops in the system.
XLR Inputs – Female balanced XLR and 1/4 inch phone jack combo input connectors.
RCA Inputs – Female unbalanced RCA input connectors.
SPK SELECT Switch – This switch determines which inputs are fed through to the amplifier. If CH1 is selected only the audio on CH1 will pass through to the speaker. If CH2 is selected only the audio on CH2 will pass through to the speaker. If MIX is selected, the audio on both CH1 and CH2 will pass through to the speaker.
THRU SELECT Switch – This switch determines which inputs are sent out of the THRU connector. If CH1 is selected, only the audio on CH1 will be sent out via the THRU connector. If CH2 is selected, only audio on CH2 will be sent out via the THRU connector. If MIX is selected, the audio on both CH1 and CH2 will be sent out via the THRU connector at a 50/50 mix. The signal sent out of the THRU connector is before the GAIN knob so any change in level via the GAIN knob will not be reflected on the signal that is sent out.
THRU Connector – Male balanced XLR output connector. This connector provides a full-range signal which can be daisy chained to another speaker.

PRX700 Amplifier Input Configuration for
PRX715XLF and PRX718XLF:

FEATURES

POLARITY Button – This push button allows you to choose between 0° (Normal) or 180° (Inverse Polarity). The correct polarity setting will produce the best blend between the subwoofer and the full-range speaker and the strongest perceived bass response at the listening position. If the bass response seems weak, try inverting the polarity.
PASS THRU Button – This push button determines whether the signal coming out of the THRU connector is unaltered (FULL RANGE) or has a high-pass filter (HI PASS) applied to it. If HI PASS is selected, a 120Hz 24dB/Octave high-pass filter is applied to the signal coming out of the THRU connector. Engaging the high- pass filter allows for a smooth transition between the subwoofer and full-range speaker that is connected to the output connector.
PWR/STBY LED – This LED illuminates when the “Power Switch” has been turned to the on position. It will illuminate BLUE when the system has power and is ready to pass audio. It will illuminate RED when the system is in power save mode and not passing audio.
FRONT LED – This push button allows you to turn on/off the Power LED on the front of the speaker. The front LED will illuminate BLUE when the system has power and is ready to pass audio. When the front LED turn RED that means the system is in power save mode and not passing audio.
SIGNAL Indicator – There is one GREEN LED that will illuminate when signal is present.
LIMIT Indicator – There is one YELLOW LED indicator that will illuminate when peak output has been reached and the DSP limiter is acting.
GAIN Knob – This gain knob is for setting the input level. The 12 o’clock position is a good starting point for most uses. Once the full-range system has been connected the level can be varied to match and deliver the desired balance.
XLR Inputs – Female balanced XLR and 1/4 inch phone jack combo input connectors.
THRU Connectors – Male balanced XLR output connector. This connector provides a FULL RANGE or HI PASS signal depending on the setting of the PASS THRU button. In addition to connecting a full-range system to the output, it’s also possible to daisy chain subwoofers together.

TROUBLESHOOTING

Symptom	Likely Cause	What to do
No sound	Speaker not connected to active AC power	Verify that speaker is

connected and that circuit is on. Switch on power and verify that illuminated logo is on.

• Re-seat the power cable at both ends.

• Substitute a known-good power cable.

Speaker power cable is faulty or improperly connected
No sound, speaker is connected to working AC power but won’t come on.| Blown fuse| • Replace the fuse with the specified value

and type.

• Take your speaker to a competent

service center.

Signal source (mixer, instrument, etc.) is not active
No sound.

Speaker comes on.

| Faulty cables and connections| • Check VU meters on the source mixer.

• Verify that the CD/MP3 is playing.

• Use headphones to verify that the

instrument is actually sending an audio signal.

• Disconnect and re-seat signal cables.

• Replace suspected cable with a

known-good cable.

No sound with microphone connected directly to the MIC input.| Microphone requires 48V phantom power| The PRX700 speakers do not supply phantom power. Switch to a dynamic microphone, use a battery in the microphone (if possible), use an external phantom power Faulty microphone cable supply. Check cable.
Faulty microphone cable
Signal sounds distorted and very loud, OVERLOAD light is lit most of the time.| Excessive input signal, trying to exceed the capabilities of

the speakers

| • Reduce the output level of the source.

• Turn down the level controls on the speaker.

Signal sounds distorted even at moderate volumes, OVERLOAD light is not lit.| Mixer or other source

is overdriven (clipping)

| Review the Owner’s Manual for your system setup and adjust controls as needed.

• Input sensitivity (gain)

• Check gain structure of signal chain

Noise or hiss heard at output| Noisy Source Device| Disconnect the devices that are connected to your speaker one at a time. If the noise goes away, the problem is with the source or the connecting cable.
Hum or Buzz that increases or decreases when the mixer level controls are moved| Improper A/C ground or faulty equipment connected to mixer input| Disconnect or mute channels one at a time to isolate the problem. Refer to the owner’s manual of the faulty equipment for troubleshooting help.
---|---|---
Faulty cable between source equipment and mixer| Substitute a known-good cable for the suspected faulty cable.
Hum or Buzz| Improper A/C grounding, ground loops| • “Telescope” the audio ground by using an XLR/F

to XLR/M adapter on one end.

• Re-route audio cable away from AC power and

lighting cables.

Excessively long unbalanced cable run| • Use the balanced outputs (if available) of your

mixer or source equipment to drive your EON speakers.

• Use a “DI” (direct injection) box to convert your unbalanced equipment output to a balanced output.

Improper system gain structure| Review the Owner’s Manual for your system setup and adjust controls as needed.

• Input sensitivity (gain)

Speakers feedback and howl when the microphone volume is turned up| Microphones are pointed into the speakers| Move the speakers so they do not point to the microphone’s pickup pattern.
Equalizer settings are incorrect| Locate the feedback frequency and reduce it using the mixer EQ or an external equalizer.
Excessive gain| Reduce the gain at the mixer and move the microphone closer to the sound source.
Too much low frequencies when playing back prerecorded music| Recorded music with excessive low frequencies| Switch the EQ switch to “flat.”
