Specifications subject to change without notice.
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

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.
