Introduction
This third edition of the Array Application Guide illustrates how Application Engineered TM and
Precision Directivity TM Series loudspeakers can provide the building blocks to construct arrays
that fit almost any room size or application. New to this edition are arrays B4, G7 and G8. Also
included in this latest edition are updated explanations for ordering weather resistant models,
general guidelines for painting AE and PD enclosures, and an AE/PD Series connector pin-out
guide to illustrate proper speaker wire terminating.
The arrays in this guide are categorized by configuration. These configurations help emphasize
the scalability of the AE and PD 5000 Series loudspeakers as the arrays are upgraded in terms
of power handling, bandwidth, and pattern control. General performance information including
frequency range, nominal coverage, SPL capability, size, and weight are provided for each
array.
Many of the arrays take advantage of the available hardware developed to rig some of the more
popular configurations. This includes the PAF Planar Array Frames. A further description of this
hardware can be found in the JBL publication: AE Series Bracket and Array Frame Handbook
available on the JBL Professional website.
Also included in this guide is a section that describes some array application examples as they
might be used in some typical rooms given various program requirements. The guide provides
notes that can assist in the final optimization of the arrays and provides references to additional
resources.
Although each room and project has its own demanding set of circumstances, we hope this
Array Guide provides some footing for understanding the wide variety of effective solutions that
are possible with the AE and PD series of loudspeakers.

Suspending Loudspeaker Arrays
IMPORTANT SAFETY WARNING!
The information in this section has been assembled from recognized engineering data and is intended for
informational purposes only. None of the information in this section should be used without first obtaining
competent advice with respect to applicability to a given circumstance. None of the information presented
herein is intended as a representation or warranty on the part of JBL. Anyone making use of this
information assumes all liability arising from such use.
All information presented herein is based upon materials and practices common to North America and
may not directly apply to other countries because of differing material dimensions, specifications, and/or
local regulations. Users in other countries should consult with appropriate engineering and regulatory
authorities for specific guidelines.
Correct use of all rigging hardware is required for secure system suspension. Careful calculations should
always be performed to ensure that all components are used within their working load limits before the
array is suspended. Never exceed the maximum recommended load ratings.
Before suspending any speaker system always inspect all components (enclosure, rigging frames, pins,
eyebolts, track fittings, etc.) for cracks, deformations, corrosion, missing, loose or damaged parts that
could reduce strength and safety of the array. Do not suspend the speaker until the proper corrective
action has been taken. Use only load-rated hardware when suspending Application Engineered™ Series
and Precision Directivity™ Series loudspeakers.
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/pub/technote/tn_v1n14.pdf).
•Know the rules for safe rigging.
•Attend a safe rigging seminar, such as that presented by professionals like Rigging Seminars™
(www.riggingseminars.com) 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 install and operate sound systems.
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

-5-
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 AE Series and PD Series loudspeakers
must be inspected for fatigue at least annually. 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 rigging hardware provided with or for
the JBL AE Series and PD Series 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 from 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.
Prior to suspending the system, an expert, trained and experienced in flying speaker systems should
inspect all rigging parts and components.
Safe Rigging
WARNING!
Suspending any loudspeaker system should be done by qualified persons following safe rigging standards.
The JBL AE Series and PD Series are supplied with built-in internal brackets. The system is designed to
facilitate the suspension of the loudspeaker by a qualified person familiar with rigging hardware and
industry practices. Threaded M10 shouldered eyebolts are available for purchase from JBL Professional
for use when suspending AE and PD Series enclosures utilizing this internal bracket system.
AE and PD enclosures are capable of a maximum load of 470lbs/213kg from 2 points equally loaded. The
single point maximum load is 235lbs/106kg. Improper installation may result in damage, injury or death.
Prior to suspending the system, an expert, trained and experienced in flying speaker systems should
inspect all rigging parts and components. A licensed Professional Engineer must approve the placement
and method of attachment to the structure prior to the installation of any overhead object.

Array Applications
The arrays described in this guide are developed to meet the performance goals of a wide
variety of applications. Array recommendations are largely dictated by the intended function of
the sound system along with the size and shape of the room. For this discussion, we will divide
the function of the sound system into three broad categories: Speech, Speech & Music, and
High-Impact Music, and describe some typical solutions to three common room types.
Referenced array types begin on page 13.
Speech Systems
A speech-only system’s primary function is to provide good intelligibility throughout the
room. For these systems, there is more of a tendency to use a center cluster system or a
more distributed approach since cost and evenness of coverage are generally driving
factors in the design. Center clusters provide good localization to the talker. Delay fills
improve gain before feedback and coverage, but at an increased cost. These systems
are typically run in mono mode.
For small to medium sized rooms, Application Engineered™ two and three-way arrays
are most appropriate. A simple single-tier solution such as array types B or C may be
appropriate if the vertical coverage requirement is less than 50 degrees (see Figure 1).
Larger rooms require higher SPL levels, better directivity, and usually a two-tiered array.
In these cases, clusters that include the AM6340 or the PD5322 will provide the levels
and broadband directivity to make these systems successful (see Figure 2).
For fan-shaped rooms or larger auditoriums, a three- or four-cluster system provides
more consistent horizontal coverage and better localization to the stage. Systems
designed primarily for speech should have as little overlap as possible between adjacent
clusters. These systems can also improve coverage close to the stage (see Figures 3, 4
& 5).
Figure 1: Array B3 (p. 19) as
Center Cluster in small theater
Figure 2: Array E4 (p. 26) as Center
Cluster with AM4212 fill speakers in
large auditorium

-7-
For larger center clusters, consider the D or E series of arrays. For three- and four-cluster
systems as described above (see Figure 3), the G series of arrays are particularly useful given
their low profile and excellent polar characteristics. The stacked LF drivers of these arrays
combine to increase LF power and directivity, improving gain before feedback. They are also
very simple to rig.
Combination Speech & Music Systems
A majority of sound reinforcement projects fall into this category. Here, all the elements
associated with a successful speech system (evenness of coverage, consistent pattern
control, and good intelligibility) need to be combined with a system that goes lower in
frequency and gets louder. These systems require a strong proscenium system to
provide source localization and solid low-frequency support.
The preferred configuration of these systems is often an exploded arrangement, although
other building constraints or preferences may dictate otherwise (see Figures 4 & 5).
Clusters must provide good directivity to lower frequencies in order to provide evenness
of coverage and improved system gain before feedback.
Figure 3: Array G4 (p. 34) used as an exploded
cluster in a fan-shaped room

-8-
Some of the array types described have subwoofers integrated into the array; others do
not. Of course, subwoofers are often a requirement for this kind of system and can
always be flown adjacent to the arrays or ground supported.
Figure 4: Array G4 (p. 34) used in an
exploded configuration in an auditorium
Figure 5: Array E3 (p. 25) used in an exploded
configuration in a fan-shaped room

-9-
High-Impact Music Systems
While these systems are also sometimes used for speech, their primary purpose
indicates that the arrays must produce high SPL Levels and have extended bandwidth by
integrating subwoofers – whether flown or ground supported – into the system.
Rectangular and auditorium shapes can have enhanced L/R only systems or exploded
cluster systems – the center channel sometimes being optimized for speech. Fan-
shaped rooms once again must use three- or four-cluster systems to provide proper
coverage and localization to the stage.
Many of the Speech-only or Speech & Music scenarios described above may be used as
a basis for a high-impact music system provided the SPL levels are high enough
(>110dB in the seating area) and subwoofers are included in the system. Similarly, the
array types described will generally be appropriate for this use if sized correctly for the
room and properly augmented with subwoofers.
Summary
These are only some examples of the uses of the array types that follow. These arrays may be
modified or augmented to meet the particular needs of the project. Hopefully, they are useful in
providing a starting point for configurations you can consider for your project.

ARRAY TIPS
Modeling Arrays in Rooms
The arrays included in this array guide have been developed to provide good coverage
consistency throughout their specified range and balanced power response throughout their
bandwidth. They are arranged to produce systems that are easy to rig and meet common
coverage and performance needs.
To better understand how these arrays will work in a particular room, it is always preferred to
model the room with EASEor a similar type of predictive analysis tool. With these tools,
array orientation and angles can be adjusted to optimize their use in the room. It is also a
good way to determine how different elements of the system – multiple arrays and fills –
combine to produce the complete solution.
EASE models for selected arrays are available on the JBL web site.
Optimizing Long-throw/Short-throw Loudspeaker Systems
Many sound reinforcement applications call for loudspeakers to be arranged in a “long-
throw/short-throw” configuration. To set-up a system like this, we recommend the following
procedure:
1) First, optimize the long-throw loudspeaker or system by itself (including separate
LF). Store your optimized trace for later reference.
2) Optimize the short-throw (downfill) speaker by itself (with long-throw off).
Note: When using a full-range downfill device, use the same high-pass as the
long-throw device. For a mid-high downfill device, use the same high-pass as
the long-throw M/H high-pass. This is important since using different
crossover points is detrimental to how the loudspeakers interact due to phase
mismatches through the crossover regions.
3) Level balance the downfill on-axis measurement to match the long-throw
loudspeaker’s on-axis measurement. This should be done above 1 kHz, where both
devices are clearly in the effective range of the waveguide. This may be done by
matching traces on an analysis system such as Smaartor TEF; or by simply
using an SPL meter.
4) With both long-throw and short-throw sections on, analyze the downfill region
again. The additional energy in this region, which resulted from the combined
contribution of the long-throw device(s) and the downfill device, may be reduced by
adding broad parametric EQ cuts to the downfill loudspeaker.
Note: The use of parametric filters introduces less phase shift between the
long-throw and downfill devices than raising the high-pass crossover point of
the downfill loudspeaker. This ultimately creates a smoother transition
between the devices.

-11-
5) If both loudspeakers are full-range devices, the addition of the down-fill device will
affect the long-throw response by increasing level in the LF region. This is usually
beneficial since the overall array will provide greater LF levels, producing a more
balanced system and better LF polar characteristics. However, this means that the
final low-frequency EQ must be done with all devices on.
Note: Below 250 Hz, treat all components of the array as one device with the
same EQ filters.
This proven procedure provides very good, consistent results for this common arrangement.
Signal Processing
Loudspeakers shown in this array guide are described in their most passive
configuration; the number of DSP channels required and amplifier recommendations
shown for each array type reflect this.
A separate DSP channel is required for the downfill loudspeakers. With the exception of
the AM4315, the low-frequency section of a three-way system or separate LF enclosure
will require an additional DSP channel, as will the subwoofers.
DSP signals for each individual array may be paralleled symmetrically. For instance,
where two loudspeakers are side by side horizontally, there is no benefit to providing
independent DSP. Level differences may be done at the amplifier if required.
Loudspeaker DSP settings may be found on the JBL web site. For the crossover
between the subwoofers and the low-frequency section, a 24 dB/octave L-R crossover
slope on each side is recommended. Also, it is good practice to use as a minimum an 18
dB/octave high-pass on the system with the corner frequency somewhere between the –
10dB and –3dB down point of the loudspeaker reproducing the lowest frequency. Refer
to the loudspeaker specifications for this data.
Low Frequency Pattern Control
Most of the arrays described in this guide have integral to them low-frequency devices
that are arranged to provide improved directivity. No special DSP techniques are
required to realize these benefits.
It is generally better to arrange LF devices vertically rather than horizontally, as the
vertical arrangement tends to collapse the vertical polar pattern, which is beneficial in
keeping energy off of the stage and projecting it into the room. Where it is important to
limit the LF energy on the stage and to gain additional level and impact, look for solutions
that stack two or more LF drivers vertically.
To further explore low-frequency arraying please refer to the following JBL white papers:

 ; JBL Professional Application Note.
4) JBL Audio Engineering for Sound Reinforcement by John Eargle and Chris
Foreman (Hal Leonard Publications, 2002).
These papers describe some of the most popular and effective low-frequency arraying
techniques for performance systems including:
•Frequency-shaded or Bipole arrays
•Gradient or Cardiod arrays
•Filtered Array Technology(FAT) arrays
•Forward Steered arrays
Each of these arrays may be realized using product from the AEand PDseries of
loudspeakers. For additional information on the use of these arrays please contact the
JBL application support staff.
Planar Array Frames and Rigging Brackets
Planar Array Frames (PAFs) provide a pre-engineered solution to rig many of the arrays
found in this guide. Please refer to the AE Series Bracket and Array Frame Handbook for
more details.
When tilting an array that utilizes a PAF frame downward at angles greater than about 35
degrees, understand that the center section of the array will end up with more down-tilt
than the outside sections. If this is undesirable, consider changing the rigging to a
spherical array, where each box is aimed down independently. Spherical arrays can
require more complex rigging, but have the benefit of independent adjustment of
speakers on each axis.
Often the top tier of a multi-tiered array is aimed downward together at a shallower angle
and the downfill boxes are aimed independently below that. This is how the two-tiered
arrays in this guide are shown.

ARRAY OVERVIEW

ArrayA5 Application Notes
A sometimes unanticipated problem in sound system design is excessive low frequency energy
beneath the flown array. Related to this can be poor low frequency coverage into the audience
area and a system with excessive ‘lobing’ onto the performance area. This is usually caused by
arranging low frequency devices in such a way they do not work together in an efficient
manner.
A single low-frequency device by itself has very little directivity. However, by spacing a pair of
low frequency devices the resulting ‘spaced-source’ array has a directivity defined by the
distance between the devices and the frequency. Additionally, spacing the drivers above and
below the MF waveguide has the effect of extending the effective working height of the system,
thus allowing the resulting array to work together smoothly through a lower frequency. This is
commonly known as a bipole array.
Not only will this reduce LF energy on the stage, thus increasing gain before feedback, it will
also have the effect of improving the evenness of coverage in the audience area.
The diagram below (Fig 1.) describes how the levels of the loudspeaker system must be
controlled in the vertical plane to achieve consistent direct levels in the seating area.
To achieve the spaced-source effect, a PD5122 is simply placed below a standard PD5322. The
low frequency device spacing creates a directivity pattern that essentially matches that of the
mid-frequency waveguide. The result is a smooth transition in directivity performance through
crossover.
Since the PD5122 is simply the LF section of a PD5322, the response of the LF sections will be
identical and they can utilize the same DSP processing settings. No additional steps are required
to realize the increased vertical directivity offered by this array configuration. Refer to JBL
