ILA is a line array system designed specifically
for installation in a variety of venues including
houses of worship, sports facilities, clubs
and other entertainment venues. ILA System
v2 is a complete system consisting of line
array, subwoofer, processing, amplification
and suspension accessories. The result is an
accessible system with very high performance,
moderate cost and ease of deployment.
Most line array systems currently available
are designed for touring applications, which
require extreme ruggedization and expensive
suspension hardware. As a result, overall
system cost is driven beyond the means of
many facilities that could benefit from line
array performance. By focusing on installation
applications, using a molded enclosure and
simplifying the rigging design, QSC has driven
cost out of the ILA System while retaining the
sound quality, coverage and power of high end
touring line array systems.
WL2082-i
Each Installation Line Array element uses a
pair of high-power, neodymium magnet, 8"
diameter low-frequency drivers. Both woofers
produce low frequencies but only one covers
the mid-range resulting in more uniform
directivity in the crossover region. For high
frequencies, a pair of 1.75" (voice coil diameter)
neodymium compression drivers with titanium
domes are mounted on a multiple aperture
diffraction waveguide* that provides extremely
wide coverage (140º). As a result, a WL2082-i
system will rarely require additional side or
center fill speakers and solid stereo imaging is
preserved across the listening area.
The system may be used in bi-amplified or
tri-amplified mode. In general, the tri-amplified
mode will produce the best performance and,
for arrays larger than four boxes, will not
increase the total cost of system amplification.
Available in black or white, the WL2082-i
enclosure is made of high impact polystyrene
with extensive internal ribs to eliminate acoustic
losses due to sidewall flex. The Installation Line
Array may be used in outdoor applications
where the system is not directly exposed
to the elements. The enclosure material is
formulated with UV inhibitors, the grille is
made of aluminum and the woofer cones are
weather resistant.
Rigging
Rigging for the ILA is simple, flexible and safe
providing a 10:1 design factor with twelve
WL2082-i systems in the array (see the owner’s
manual for details before planning any array
suspension). The array is assembled with the
included bolts and the relative angle between
adjacent boxes is adjustable in 1º increments
for precise tailoring of vertical coverage. For
those who prefer quick release pins to the
included bolts, an optional kit of four quick
release pins (QRP-KIT-1) is available.
Subwoofer
The subwoofer for ILA System v2 is the
WL118-sw, a single 18" version of the popular
WideLine-10 touring, dual 18" subwoofer and
offers an impressive combination of punch
and low-frequency extension. ILA subs may
be suspended at the top of an ILA array using
the standard FP2082-i array frame. When trim
height is limited, the ILA sub may be suspended
behind the array using the available EB2082-i
extension bar.
