This provides smoother pattern control at the mid-high cross-
over. With selectable shading, the enclosures can be used as
house right or left by flipping the switch, not the enclosure.
Introduction
The WideLine loudspeaker system has been designed to pro-
vide a compact system that has similar power handling, fre-
quency response, and coverage of larger systems. Its primary
uses include ballrooms, theatres, night clubs, houses of wor-
ship, and small to medium size events for the corporate/indus-
trial market.
The enclosure is constructed of lightweight cored-composite
and weighs only 70lbs. (31.8kg), including the self-contained
rigging hardware. The hardware allows for simple vertical
splay angle adjustment of 0, 2, 3, 4, 5, 6, 7, 8, 9, and 10°
between enclosures. Two array grids are available. The small
array frame supports up to 8 enclosures flown or 4 enclosures
stacked. The large array frame supports up to 24 enclosures
flown or 12 enclosures stacked.
The WideLine system is suitable for stand alone applications
as a full range, articulate, high fidelity, sound reinforcement
product with the ability to reproduce almost any musical pro-
gram without subwoofers or bass modules. It has bass
response to 52 Hertz (-3 dB) in a small format package. Its 3-
way, biamp or triamp design keeps required amplification to a
minimum.
WideLine users can also use a software tool called EASE
Focus to aid in the design and implementation of a WideLine
array. EASE Focus can calculate the number of enclosures
required for a given space (venue), determine the optimum
splay angle between those enclosures, calculate at what
angle to set the array grid in a single (variable) pick-point or
fixed suspension point application, and predict the acoustical
response and sound pressure levels throughout the venue in a
two-dimensional illustration. The software is available sepa-
rately; downloadable from the QSC website or contact QSC for
more information.
WideLine’s exceptionally wide dispersion practically elimi-
nates the need for “side” or “fill” hangs when used as the
main array. Its wide dispersion also provides enhanced cover-
age when used as a center cluster or as a downfill or under-
hang enclosure when used with larger format line array
systems.
Wide dispersion is accomplished with a 3” (76mm) diaphragm,
1.4” (36mm) exit neodymium high-frequency driver mounted
on a proprietary, patent-pending multiple aperture diffraction-
slot waveguide. This device is the ideal linear source needed
for line array performance.
Like all ISIS products, WideLine design focuses on accurate
audio performance, rapid set-up, and reduced labor requir-
ments. Ease of transportation, assembly, use, and self-con-
tained rigging hardware make WideLine the clear choice.
Combined with the ISIS 82H, 102M, 102W, 122M, 152M,
215PCM, and 215SB, the WideLine array system provides the
most comprehensive toolbox for any sound reinforcement pro-
fessional.
Internal, mid-frequency shading can be switched to either 10”
(254mm) transducer. Both transducers handle the low-frequen-
cies, but only the non-shaded transducer handles the mids.

Three way Active/Two way Active Switch
Two way active: The “full range” LF input is applied to pins 1+ and 1- and the -6dB per octave shading
network is applied to one of the LF transducers using the Low Frequency Select switch (above).
Three way active: Shading network is NOT applied (shading must be provided by upstream signal pro-
cessing). Connect the full-range input signal to pins 1+ and 1-, connect the shaded (processed) signal to
pins 2+ and 2-. To flip shaded transducer location, use the Low Frequency Select switch or alter signal
processing. Default Low Frequency Select switch position for three way mode is position A; if put in
position B, connections (per Table 1) to LF transducers A and B are interchanged.
Low Frequency Select Switch
The WideLine is a three way design (shaded, non-shaded and high frequency) with shading provided by
a passive network in two way mode or upstream signal processing (DSP) in three way mode. This allows
switch position selection for use as either “house left” or “house right”, without the need to flip boxes.
Two way Mode: The shading switch allows either low frequency transducer to be selected as the
shaded unit (bass only) by inserting a -6dB per octave network. The switch handle points to the side of
the non-shaded (full range) low-frequency transducer.
Three way Mode: The internal -6dB per octave network in NOT applied to either LF transducer. Shad-
ing is accomplished with signal processing. The switch handle points to the side of the non-shaded (full
range) low-frequency transducer ONLY IF the full range signal is applied to pins 1+ and 1- and the
shaded signal to pins 2+ and 2-. Default position for three way mode is position A; if put in position B,
connections to LF transducers A and B are interchanged.

Input Connections
The input connectors are a pair of Neutrik NL8's wired in parallel. Connections for biamp and tri-
amp vary, see Table 1. The pin designations for the NL8FC cable connector is shown for reference,
bottom right.
Note! In three way mode, the Low Frequency Select switch position determines the
input connector wiring! Unexpected results may occur if switch positions and wir-
ing are not strictly controlled.
The WideLine loudspeaker is not equipped with a crossover network. All signal
processing must be done before connecting audio power to the loudspeaker. Do not
connect full-range audio to the high-frequency transducer or damage may result!

Rigging
CAUTION: SUSPENDING SPEAKERS PRESENTS A RISK OF SERIOUS
INJURY OR DEATH. PLEASE USE CAUTION TO ASSURE THAT
MOUNTING SURFACES ARE CAPABLE OF SUPPORTING AT LEAST
FIVE TIMES THE WEIGHT OF THE SPEAKER AND MOUNTING APPARATUS.
USE ONLY LOAD RATED HARDWARE. ALWAYS CONSULT WITH A CERTIFIED
PROFESSIONAL WHEN IMPLEMENTING OVERHEAD SUSPENSION.
Front Articulated
Joint- Slide the joint
out of the receiver tube
by sliding the retaining
screw upward, then
lock in place using the
ball-lock pin.
The large array frame’s maximum array is twenty-four (24) enclosures. Weight of a
twenty-four box system is only 1680lbs and the large array frame weighs 83lbs.
The small array frame supports a maximum of eight (8) enclosures with a system
weight of 420lbs. and frame weight of 33lbs. The rigging hardware does not allow
array assembly with any enclosure inverted.
The rigging system for WideLine has been engineered to achieve a minimum of
the industry standard strength ratio of 5:1 with 24 enclosures on the large array
frame or 8 enclosures on the small array frame. Palos Verdes Engineering has cer-
tified the mechanical calculations, and destructive tests have been performed by
ATM Flyware.
WideLine enclosures use a three-point suspension system. The system consists of
front, left/right, captive articulated joints and a single rear link blade. Articulation
is in 2° increments using the first location on the link bar. With the use of the sec-
ond location, 1° degree increments can be obtained starting at 3°. The total avail-
able angular increments are: 0, 2, 3, 4, 5, 6, 7, 8, 9, and 10°. All pieces and locking
pins remain with the enclosures. No ancillary items are needed to fly the enclo-
sures from the WideLine grid. All ball-lock pins are equipped with a lanyard to
help prevent loss.
Front Articulated Joint (Knuckle) Hardware
Expose the end of the articulated joint by locating the joint’s retaining screw pro-
truding from the front of the receiver tube and sliding it upward. The front captive
joint will slide upward from the enclosure’s receiver tube.
The exposed end of the articulated joint can now be inserted into the adjacent
enclosure’s receiver tube and locked into position by a locking pin. This is repeated
for each side of the enclosure. Then the rear link blade can be rotated into position
and pinned at the chosen degree increment.
Rear Link-Remove the
ball lock pin from the
storage position, then
rotate the link down-
ward to the adjacent
enclosure. Lock in place
using the ball-lock pin.
Rear Link (Angle Adjust) Hardware
The rear link is stored with the link folded between the sides of the block. To
expose the link, remove the ball-lock pin and rotate the link into the desired posi-
tion. Once positioned, the link is secured using the ball-lock pin of the adjacent
enclosure.
The rear link is marked with a thin, white line at the “normal” (0°) position and
with a “+3” at the +3° position.
The additional ball-lock pin hole (located approximately midway on the link) is
used for storing the link when folded into the enclosure’s block for storage. The
link may be pinned in place at the 0° or 8° location on the block when rotated into
the storage position.

Adjusting the Angle Between Enclosures
(Splay)
The illustration shows the rear pin block of two enclo-
sures joined by the upper enclosure’s rear link arm.
Use the first pin location (closest to the end) on the link
arm for setting in normalized 2° increments. The left-
side example shows two enclosures linked for 8° of
splay. The ball-lock pin is inserted into the 8° position
in the rear block while passing through the “normal”
pin hole in the link.
When the "+3" location is used, an additional 3° are
added to the "normalized" location. The right side
example shows two enclosures linked for 9° of splay.
The ball-lock pin is inserted into the 6° position in the
rear block while passing through the “+3°” pin hole in
the link. The total splay is the 6° indicated on the block,
plus the 3° additional from the link position, for a total
of 9°. In this manner 1° increments can be attained
starting with 3° (0° block location and +3° link arm
location).

Array Frames (Fly Grids)
There are two array frames available for the WideLine
system.
The large frame is used for flying a typical four to
twenty-four-box array. The large grid may be inverted
and used to stack up to twelve or more enclosures.
A compact and easier to handle frame is available for
use as a small array, four or less, stacking or fly grid.
This grid will easily sit on deck stacked bass enclosures
or it can be used at those smaller events to fly clusters
from the stage trusses.
Large Array Frame (Fly Grid)
Do not fly (suspend) more than twenty-four
(24) enclosures form the large array frame.
Do not stack more than twelve (12) enclo-
sures on a large array frame.
Use only 5/16” diameter x 1.25” long ball-
lock pins on front receiver tubes.
The three pick up rails allow for any number of rigging
solutions to fit the most demanding venues. The rails
are drilled for industry standard 5/8" shackles.
7
Large Array Frame (continued)
The mounting plate and link on are located on the bottom side of the frame assembly. Use this link for attaching the rear of the first
enclosure. The grid allows for up or down angle options for use with either stacking or flying. The 4° “normal” locations on the link sys-
tem will yield a net 0° vertical inclination.
Use 4° link location for
0° vertical inclination
Small Array Frame (Stacking Grid)
Do not fly (suspend) more than eight (8) enclosures form the small array frame.
Do not stack more than four (4) enclosures on a small array frame.
Use only 5/16” diameter x 1.25” long ball-lock pins on front receiver tubes.
The small frame will easily handle four enclosures and will interface with the QSC 215PCM or 215SB subwoofer in both a stacked or
flown configuration. The stacking bumpers on the frame may need to be moved to the opposite side of the frame member for use. The
small frame is constructed using standard “L” track for rigging.
8
Stacking the Small Array Frame
The small array frame comes with two aluminum I-bars used for aligning and securing the frame to QSC’s “215” subwoofer.
To use the I-bars, simply slide each one into the small frame’s L-track and secure with a stud fitting. Then, turn the frame over (I-bars on the
bottom) and slide the exposed I-bars into the subwoofer’s L-track. Secure the I-bar with a stud fitting. Note that the stud fittings used are
not required to be load rated as they only retain the I-bars from moving laterally.
When stacking a small array frame on top of
QSC’s 215SB or PCM cabinet, use the I-beam
inserts (1 in each L-track) to assure proper align-
ment and to firmly secure the frame to the 215
cabinet. Secure using stud fittings.
Do not stack more than four (4) enclosures on a
small array frame.
Care
The socket head cap screws used on the WideLine products are load-rated high-strength steel, not stainless steel. Stainless screws are not
rated to handle the necessary load. Should any hardware require replacement, contact QSC’s Technical Services for spare parts.
The rigging hardware is stainless steel which has been black oxide coated. The oxide coating is not corrosion-free.
We suggest wiping down all screws, pins, hardware, and frames with LPS ® Dry Film Lube or Starrett M1® All Purpose Lube before and
after outside gigs to help prevent oxidation. This will not only prevent the formation of rust and other oxides, but also provide lubrication,
adding to the longevity and ease-of-use of the WideLine product.
