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.

Array Configurations
The following table provides information regarding the maximum number of WL2082-i line array
elements and WL118-sw subwoofers that may be suspended using various configurations of
the available suspension accessories. The calculations for this table are based on a 10:1 design
factor. See owner’s manual for detail before designing or suspending an array. While a single
WL2082-i may be used for some specialized applications such as stage lip front fill, or under
balcony fill, three or more ILA elements are required before the system begins to perform as a
true line array.

Aiming the ILA System v2
Aiming and array configuration of an ILA System is supported by EASE
Focus, a two-dimensional acoustic simulation application that calculates
vertical coverage of a venue by a line array system. This free software
may be downloaded from the support section of the QSC website at
qscaudio.com.
Intrinsic Correction™
Modern line arrays rely on digital signal processing to perform their best. QSC has developed a
sophisticated approach to creating system tunings that improve performance and dramatically
simplify system set-up. Intrinsic Correction is far more than just signal processing. It is also
a process that begins by taking extensive laboratory measurements (typically 60-75) of the
loudspeaker and then spatially averaging those measurements. Once the spatially averaged
response of the loudspeaker is determined, a combination of IIR and FIR filters is applied to
adjust the time, frequency and amplitude response to a maximally flat band-pass target.
The result is that signal processing adjustment is no longer a task requiring complicated test
gear, prolonged measurements and golden-eared experts. The QSC SC28 System Controller
offers preset recall simplicity. Just input the size of the array, the included coverage angle and
the amplifier model numbers. The SC28 does all the needed calculations. While it’s simple to
use, the SC28 offers audio quality so good it’s being used on major concert tours.
For applications requiring networked audio and more complex signal routing, BASIS™ processors
also support ILA.
