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.  
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.  
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.  
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.  
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.  
Subwoofer  
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.  
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.  
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  
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
