BEFOREYOU BEGIN
Welcome to the family of discerning sound equipment users who have selected JBL Professional loudspeakers.
This Users Guide contains important information that will help you get the most from your JBL speakers so
please take a few moments to read it and be sure to keep it in a safe place for future reference.
Important Information
Before using your SR-X Series speaker system, please review the following for important information on safety
and protection of your investment in quality loudspeakers.
Rigging / Suspending SR-X Products
SR-X Series speakers are designed for portable applications in which the speakers will be stacked directly on
the floor, stage, speaker stands (SR4702X, SR4722X only), other speakers, or a solid, stable platform. SR-X
Series speakers have no provisions for hanging, rigging or suspension.
SR-X/F Series speakers are similar to SR-X and in addition have provisions for flying.
SR-X/F versions should always be substituted for SR-X if flying or suspending the speaker system is required.
ONLY SPEAKERS SPECIFICALLY DESIGNED FOR FLYING / RIGGING SHOULD BE SUSPENDED. For
further information on suspending speakers contact JBL and request Technical Note Volume 1, Number 14 -
"Basic Principles for Suspending Loudspeaker Systems".
Stand Mounting
Some SR-X models (SR4702X, SR4722X) include a receptacle cup to facilitate mounting on tripod stands.When
using these stands, be sure to observe the following precautions:
•Check the stand specification to be certain it is designed to support the weight of the speaker. 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, crew, and audience will not trip over them and pull 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.
•Always be cautious in windy, outdoor conditions. It may be necessary to place additional weight (i.e. sand-
bags) on the base of the stand to improve stability.
Stacking Speakers
Safety precautions should be observed when stacking SR-X speakers.
•Verify that the floor or stage on which the speakers will be stacked is flat, level and solid.
•When used outdoors, be aware of winds that could tip a tall speaker stack over.
•Position the speakers to minimize the possibility that performers, crew, or audience will bump into them.
•Under extreme, high-SPL conditions it's possible that speakers on a highly polished surface can "creep."
(i.e. move due to the power of the acoustic energy) Precautions should be taken so that such creeping will
not result in toppling of the speaker stack.
Hearing Damage, Prolonged Exposure to Excessive SPL
SR-X series loudspeakers are easily capable of generating sound pressure levels (SPL) sufficient to cause
permanent hearing damage to performers, production crew and audience members. Proper precautions should
be taken to avoid prolonged exposure to SPL in excess of 85dB.
Exposure to Moisture, Outdoor Applications
While SR-X Series loudspeakers will work great for outdoor sound reinforcement, they are not "weather-proof"
and are not intended for continuous exposure to extremes of humidity, temperature, salt air, or UV rays.
Exposure to outdoor environmental conditions may result in premature failure of components as well as
degradation to appearance.

PRODUCT RANGE
The SR-X Series consists of 11 popular configurations including subwoofers, front-of-house systems, and stage
monitors. SR-X models include these features:
•Metalized polyester capacitors are used throughout (instead of cheaper electrolytics) for higher power
handling and lower distortion.
•"Dual-mode" crossovers can be easily switched from full-range to bi-amplified operation. A tamper-resistant,
internal mode selector provides a visible, external indication of the selected mode.
•Dual driver subwoofers may be operated in parallel or discrete mode.
•VGC™ (Vented Gap Cooling) low-frequency transducers control heat build-up to increase power handling
and decrease power compression, providing more acoustic output for every watt of amplifier input.
•13 ply birch enclosures are finished in tough DuraFlex™ that resists the inevitable scuffs and dings a
hard-working speaker suffers during a life of one-nighters.
•Pure titanium diaphragm compression drivers are used in all two & three-way models for high power
handling and reliability.
•Optimized Aperture™ horn/driver combinations reduce throat distortion and provide smooth frequency
response.
•A non-resonant, full-length perforated metal grill provides protection for the components and a rich yet
unobtrusive appearance.
•Trapezoidal enclosures (except SR4715X, SR4718X, SR4719X, SR4702X) for optimal coverage when
splaying multiple cabinets.
•Family footprint on the most popular models provides ease of stacking for larger, full-range systems
Stage Monitor
SR4702X
12" two-way stage monitor: With 600 watts of power capacity and 95 dB sensitivity, the
SR4702X delivers all the output needed to cut through high stage volumes. Its compact
footprint won't crowd the stage and the low profile won't come between the performer
and the audience. For increased flexibility, a tripod mount socket is provided to facilitate
use as a front-of-house speaker. A "pass-thru" speaker connector allows cleaner
connection of adjacent cabinets driven by the same amplifier.

of two VGC LF motors and the cone area of dual 12"
speakers, the SR4731X produces incredible
amounts of mid-range power combined with lots of
tight, punchy bass.The transition from the 12" LF
drivers to the large format 2447 compression driver
is very smooth. For extremely high-power
applications requiring earth-moving bass, use
the SR4731X over the SR4719X subwoofer.
SR4733X
Dual 15" two-way system:The SR4733X delivers the
power and performance of separate subwoofer / high-mid
configurations combined with the simplicity of an all-in-
one system. At home in a wide range of live sound and
playback applications, the SR4733X delivers very high
acoustic output combined with lots of extended low bass. 5

Three-Way Systems

pounding bass down to 30 Hz. A top mounted, 35 mm
diameter socket is provided for an optional pole (JBL model
SS3-BK) to elevate a speaker such as the SR4702X or
SR4722X above your subwoofer.The socket is intended to
accommodate speakers up to 100 lbs (45 kg). Observe the
stand mounting precautions outlined in the "Before You
Begin" section of this User's Guide.
SR4715X
Dual 15" subwoofer: For those who prefer the tight, punchy bass of
a 15" sub, the SR4715X is the answer.The SR4715X has the same
footprint as the other SR-X 15" two-way systems (including the dual
LF models) for tight floor stacking.
SR4719X
Dual 18" subwoofer: Capable of delivering a wall-shaking 136 dB of
acoustical output with a frequency range extending to 25 Hz, the
SR4719X is the choice for large rooms, outdoor performance and

SPECIFICATIONS
DuraFlex
The SR-X loudspeaker system is finished in JBL's DuraFlex™. DuraFlex is tough and inherently flexible and it is
extremely resistant to knocks, scratches and scuffs.The DuraFlex finish on your SR-X speakers is actually much
tougher than the plywood to which it is applied. Note: SR-X enclosures are not paintable. In the event that
cosmetic damage occurs to your speakers, a DuraFlex touch-up kit (PN 16677) is available from JBL.
Recommended Power
The following table shows the recommended amplifier power for SR-X models.
1.Full-range / Parallel: Is the amplifier power required to optimally drive this speaker system when used in full-
range (passive) mode. In the case of dual-driver subwoofer models, this is the power required to drive both
transducers at the same time.
2.HF: Is the amplifier power required to optimally drive the high-frequency section of this speaker system when
used in bi-amp mode.
3.LF: Is the amplifier power required to optimally drive the low-frequency section of this speaker system when
used in bi-amp mode.
4.Discrete: Is the amplifier power required to optimally drive an individual transducer in a dual transducer
subwoofer.
5.±1 or ±2 Pass-Thru: This allows for the convenience of a single conductor cable from the amplifier rack to the
speakers stack, this configuration supplies separate amplifier power to the subwoofer (ie ±2) and to the
mid-high speaker (ie 1 Pass-Thru).

CABLE AND CONNECTIONS
Passive Systems & Subs (Parallel Mode)
Bi-Amp Systems & Subs (Discrete Mode)
Wire Gauges
Each connector panel incorporates two Neutrik® Speakon® connectors. The second connector facilitates the
ability to "loop through" to other SR-X speakers in the system.The diagrams below detail the cable-side
connections.
Selection of the appropriate wire gauge is important to system operation. A cable that is too light will result in
amplifier power being wasted due to the series resistance of the cable and in loss of low-frequency performance
due to degraded damping factor.

INPUT PANEL
Internal Network Mode Selector
All SR-X models are fitted with the internal network mode selector.
The ability to select the mode of operation provides the sound system user flexibility
in the system configuration, and also permits the system to be upgraded at a later
date. By simply removing the input panel and changing the position of a heavy duty
connector, the system can be configured as either a bi-amp or a passive system.
After replacing the input panel, the network position is indicated on the connector
plate panel.This provides a truly tamper resistant solution to avoid the horrors of a
mis-configuration.
In passive operation, a system can be operated with a minimum of only one
amplifier and no additional system controllers. In bi-amp operation, the system can
be operated for maximum transducer performance and will require the use of
additional amplifiers-and an electronic crossover (see "Crossovers and Controllers").
For Sub systems with more than one transducer, the same ability to select the mode
of operation is provided - but instead of bi-amp/passive selection, the input can be
configured for either parallel woofers (4 ohm) or individual transducer access
(2 x 8 ohm).This can be useful for assuring maximum power transfer from the
amplifier to the transducers.
Please Note:There are no passive network components in the circuit when the
Bi-amp mode is selected. (Except: SR4732X and SR4735X which retain a crossover
section between midrange and HF.)
Changing the Input Mode Connector
1. Remove 6 connector plate retaining screws and
remove the plate.
2. Turn plate over and locate the male connector.
3. Pull out connector and firmly place in socket of
desired system mode - you should be able to see
the yellow indicator in the desired mode window.
4. Replace plate and secure with 6 screws.
Please Note: For SR4715X - SR4719X, the connector is
split to permit discrete mode operation.

CROSSOVERS AND CONTROLLERS
Digital System Controllers
Digital signal processing technology has made it possible to build sophisticated loudspeaker system controllers
that incorporate into a single unit, the ability to control crossover frequencies, slopes, and filter topology. In
addition, these units may include graphic and parametric equalization, time / phase alignment, and compression /
limiting. Some of these digital system controllers include factory-programmed presets for SR-X series
loudspeakers. As this manual goes to press, these controllers include the JBL DSC260, and the dbx®
DriveRack™ and DriveRack™ PA products.
If you are using a digital system controller that does not include pre-programmed presets for SR-X series loud-
speakers, it may be useful to review the JBL DSC260 settings as a starting point for programming your controller.
A PDF download detailing these settings may be found at www.jblpro.com/pages/tunings/ srx_dsc260.pdf.
Note that various processors will respond to these settings in different ways, so you will probably need to refine
your settings by ear or with the help of acoustical measurement equipment.
As with any software driven device, it is always good practice to check with the manufacturer of your digital
system controller for updates. JBL will also attempt to post notifications of any new developments at

CROSSOVER/ALIGNMENT DELAY/GRAPHIC EQ/PARAMETRIC EQ/AUTO/EQ
SR-X series loudspeakers may be operated in bi-amplified mode. In this mode, all crossover components are
bypassed (except in the case of the three-way SR4732X and SR4735X) and the voice-coils of the drivers are
connected directly to the power amplifier outputs. When operated in this manner, an external, electronic
crossover is required. Such crossovers may be cards or modules that can be installed in the power amplifiers or
may be separate processors.
SR-X series speakers include CD (constant directivity) horn designs. A characteristic of this type of horn is that it
requires a power response correction consisting of a 6 dB per octave rise beginning at approximately 4 kHz. This
power response correction is built into the passive networks of SR-X series speakers. When used in bi-amp
mode, the power response correction must be provided by the electronic crossover. Most analog crossovers will
include a "CD Horn EQ" function.

Prior to suspending the system, an expert, trained and experienced in flying speaker systems should inspect all
components for cracks, deformations, corrosion, missing parts or damaged parts that could reduce strength and
integrity of the system. For further information on precautions and rigging techniques, see JBL Technical Note
Volume 1, Number 14.This document is available in the Technical Reference section of www.jblpro.com
The rigging track used on SR-X/F models can accommodate both 10 mm forged shoulder eyebolts and detach-
able track fittings.When using 10 mm forged shoulder eyebolts with SR-X/F, always use a 10 mm washer
between the track and the eyebolt/ Failure to do so can result in damage to the track and unsafe suspension of
the speaker system.The the event that the track is damaged, the speaker should not be suspended until the
damaged part is replaced. A kit containing 10 mm forged eyebolts and washers is available from JBL
Professional Parts (PN: 229-00017-00).
When used with an appropriate eyebolt and washer (see above) the SR-X/F suspension system has a working
load limit (WLL) of 400 lbs. (181 kg.) per point with a 7:1 design factor. When used with an appropriate track fit-
ting, the SR-X/F suspension system has a working load limit (WLL) of 500 lbs. (227 kg.) per point with a 7:1
design factor.
Suspension or flying speaker systems requires training and expertise. Improper rigging of a flying speaker may
result in injury, death, equipment damage, and legal liability.This User Guide is intended to provide a skilled
system rigger with resources needed to get the most from the SR-X/F speaker system.This User Guide will not
provide the novice with the skills and training needed to safely fly a speaker system. If you lack the skills,
training, and proper ancillary equipment to fly a speaker system do not attempt to do so. Obtain the services of a
qualified rigger or get the proper training yourself.
The SR-X/F models are equipped with ATM FLY-WARE® rigging hardware. Only hardware rated for overhead
suspension and certified in accordance with appropriate safety standards should be used to fly speaker systems.
