PRECAUTIONS  
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.  
Suspension of Loudspeaker System  
Before attempting to suspend your JBL loudspeakers, read and understand the following safety information.

SUSPENSION OF LOUDSPEAKER SYSTEMS  
Are You New to Rigging?  
If you are new to rigging, you should do the following:  
• Read and study JBL Technical Note Volume 1, Number 14: Basic Principles for Suspending Loudspeaker  
Systems (available at http://www.jblpro.com/catalog/support/getfile.aspx?docid=296&doctype=3).  
• Know the rules for safe rigging.  
• Attend a safe rigging seminar, such as that presented by professionals like Rigging Seminars™ or by Chain  
Motor Hoist manufacturers like Columbus McKinnon Corp. (manufacturers of the C/M Lodestar).  
• Meet and establish a relationship with a licensed mechanical or structural engineer. Get in the habit of asking  
them questions instead of guessing about their answers. Learn from what they tell you.  
• Meet and discuss this aspect of your business with your Insurance Agent.  
• Research and understand the codes, practices, and requirements in the venues where you intend to  
operate your sound system.  
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 suspendable 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.  
JBL is not responsible for the application of its products for any purpose or the misuse of this information for  
any purpose. Furthermore, JBL is not responsible for the abuse of its products caused by avoiding compliance  
with inspection and maintenance procedures or any other abuse.

Safe Rigging  
JBL suspendable version loudspeakers are supplied with built-in internal brackets. The systems are designed  
to facilitate the suspension of the loudspeaker by a qualified person familiar with rigging hardware and industry  
practices. Improper installation may result in damage, injury or death.  
If you are unfamiliar with Safe Rigging Practices you will need to consult with a qualified person familiar  
with rigging hardware and industry practices.  
Working Load Limit  
Working Load Limit for M10 Suspension Points:  
The working load limit (WLL) of the JBL PRX700 Series loudspeakers utilizing M10 attachment points will be  
maintained with a safety factor of 5:1, provided no more than 470lbs/213kg from 2 points equally loaded, or no  
more than 235lbs/106kg maximum from a single suspension point, is utilized in conjunction with industry  
recognized safe rigging practices and the guidelines established within this manual.  
For permanent installation applications utilizing the M10 suspension points order JBL 229-00009-01.  
This kit includes three M10 x 35 mm forged shoulder steel eyebolts with washers.  
WARNING  
Suspension of JBL loudspeakers must employ a minimum of two attachment points. When “bridling” a JBL  
loudspeaker system, two legs of equal length must be used. The rear attachment points are pull-back points and  
are intended only for use in adjusting the down-angle of the speaker enclosure. Only the top and bottom  
attachment points are intended for use as suspension points.  
Hearing Damage, Prolonged Exposure To Excessive SPL  
PRX700 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.

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.

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  
1. Selectable System EQ  
a. 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.  
b. 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.  
2. 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.  
3. 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.  
4. SIGNAL Indicator – There are two LED indicators (one for each channel) that will illuminate GREEN when  
signal is present at the input connector.  
5. LIMIT Indicator – There is one YELLOW LED indicator that will illuminate when peak output has been  
reached and the DSP limiter is acting.  
6. GAIN Knobs – This gain knob is for setting the input level of CH1 and CH2.  
7. MIC/LINE Button – This push button allows you to choose between MIC or LINE level on CH1 only. CH2 is  
always line level.  
8. 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.  
9. XLR Inputs – Female balanced XLR and 1/4 inch phone jack combo input connectors.  
10. RCA Inputs – Female unbalanced RCA input connectors.  
11. 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.  
12. 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.  
13. THRU Connector – Male balanced XLR output connector. This connector provides a full-range signal  
which can be daisy chained to another speaker.

FEATURES  
1. 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.  
2. 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.  
3. 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.  
4. 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.  
5. SIGNAL Indicator – There is one GREEN LED that will illuminate when signal is present.  
6. LIMIT Indicator – There is one YELLOW LED indicator that will illuminate when peak output has been  
reached and the DSP limiter is acting.  
7. 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.  
8. XLR Inputs – Female balanced XLR and 1/4 inch phone jack combo input connectors.  
9. 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.
