Designed for the most demanding concert and installation audio
professionals, the WideLine-8 system sets new standards for astonishing
acoustical performance and compact size.

Line arrays are increasingly employed in a wider range of venues and
applications. Frequently these venues have height or sightline restrictions
that limit the placement and size of the array. Rising fuel costs are putting
pressure on touring system providers to downsize their transportation
requirements. At the same time, client and audience expectations for
audio performance has never been higher. To meet these needs, QSC
embarked on a program to develop the most compact, highest output line
array speaker system available.

QSC’s WideLine-8 packs full size line array performance into an ultra
compact package measuring less than 20" (508 mm) wide and 9"
(229 mm) high. The WideLine-8 applies to audio the classic hot rod, high­performance formula – putting the most horsepower available into the
smallest chassis possible.

Each tri-amplified WideLine-8 element uses a pair of high-power,
neodymium magnet, 8" low-frequency drivers. Both cover low frequencies
while only one extends into the mid range, thus maintaining horizontal
dispersion control at crossover. High frequencies are handled by a
premium, 3" diaphragm, neodymium compression driver mounted to
QSC’s patented, 140º multiple aperture diffraction waveguide. WideLine
signature wide coverage delivers a broader stereo image, reduces the
need for supplemental fill speakers and allows more placement options.

The waveguide exit extends nearly to the top and bottom of the enclosure to
create a continuous acoustical source with minimal discontinuities between
adjacent elements resulting in greatly reduced destructive interaction.

The WideLine-8 sub sets a new benchmark for extraordinary acoustic
output from a miniscule enclosure. At first glance, the enclosure seems
too small to even house its pair of 4" voice-coil, long-excursion 12"
woofers, yet it produces 135 dB (peak) SPL and has LF extension to
32 Hz, with the punch needed for popular music. The extremely low
profile of the WL212-sw sub (less than 15") also makes it a great choice
for installed and portable use under a stage or in other tight quarters. The
4th order bandpass design matches the width of the WideLine-8 elements
allowing it to be flown inline with or behind a WideLine-8 array.

Premium materials are used throughout the system. The enclosure is
constructed of Baltic birch plywood and coated in an environmentally friendly,
waterborne polymer finish that is field repairable. To keep the weight to a
minimum and prevent rust, suspension fittings are made of aluminum.

An elegantly simple 4-point suspension system combined with light weight,
compact size and excellent handling ergonomics mean that a one person
crew can easily deploy an array. A single AF3082-L array frame suspends
up to twelve line array elements or up to twelve line array elements plus
four subwoofers. The WideLine-8 system is equally at home in the air or
ground-stacked.

Special attention is given to ground-stacked applications. The WideLine-8
sub suspension system includes a unique provision that allows the lowest
line array element stacked over a sub to be tilted up or down by as much
as 10º, offering better coverage of listeners near the stage. WideLine-8
subs may be used as a base for stacking up to six WideLine-8 elements.

WideLine-8 System Configurations

Flexible Arrays

Arrays can be assembled using only WL3082 line
arrays modules, with WL212-sw subwoofers at
the top of the array, or by utilizing the EB3082
extension bar, subwoofers can be flown behind
the main array.

Arrays of up to twelve WL3082 modules,
with four WL212-sw subwoofers flown behind
can be accommodated by the combination of
2 x AF3082-S small array frames and a single
EB3082 extension bar (Figure A). As many as
twelve WL3082 modules can be suspended

using one AF3082-S (Figure B) while the
AF3082-L large array frame can be used to
assemble arrays of up to 12 x WL3082 modules
alone or suspended below up to 4 x WL212-sw
subwoofers (Figure C). The AF8-10 adapter frame
(not shown) allows the user to add WL3082
WideLine-8 arrays beneath WL2012 WideLine-10
arrays. The PB3082 pullback bar (not shown) can
be used to attain extra down-angle in flown arrays
or as a suspension bar for arrays of up to eight
WL3082 modules.

Optimized Ground Stacking

WideLine-8 rigging doubles as an optimized ground stacking system. Using the WL212-sw subwoofer
as a base, arrays of WL3082 line array elements can be aimed downward by as much as ten degrees to
cover audience areas close to a stage, as well as upward by as much as ten degrees in order to better
cover distant balcony seating areas.
