WL2082-i-BK,  Black - Line Array Speaker ILA Series, QSC

Accessible, affordable, accurate.

ILA is a line array system designed specifically for installation. 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.


An ILA system doesn't require set up by an expert user with sophisticated acoustical measurement equipment. The SC28 system controller offers simple preset recall processing. While it's simple to use, the SC28 offers audio quality so good that it's being used on major concert tours. To achieve this combination of simplicity and performance, QSC developed the proprietary Intrinsic Correction™ process.


Most line array systems currently available are designed for touring applications. Touring requires 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 drove cost out of the ILA system while retaining the sound quality, coverage and power of high end touring line array systems.


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.

What's new for version 2?

An upgraded subwoofer, the WL118-sw is a single 18" version of the popular GP218-sw touring subwoofer that offers offers an impressive combination of punch and low-frequency extension. The addition of the SC28 System Controller with its simple-to-use presets, has greatly improved the ease of deployment of the system and the sound quality markedly enhanced.

  • More information about the SC28

CMX Series Power Amplifiers

  • Proven, reliable amp with superb sound quality
  • Presets are pre-programmed into the SC28 processor
  • High power - only 3x CMX2000V amplifiers plus one CMX800V needed to power a pair of 6+2 arrays
  • More information about the CMX Series

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 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.

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. For installations in which the subwoofers are ground stacked, the GP118-sw offers identical performance but omits the ILA-compatible suspension hardware.

Array Configurations

The following table provides information regarding the maximum number of WL2082-i line array elements and WL115-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 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.

EASE Focus™

To determine the array position and box-to-box splay angles, EASE Focus software is available free from the QSC web site.

Here are a few simple rules to keep in mind when configuring an ILA (or any other line array) system.

Arcuate arrays and spiral arrays will always produce the best results. The use of straight arrays and convoluted arrays is discouraged. For more detail on why, download Mark Engebretson's White Paper on Intrinsic Correction.

While the ILA will accommodate splay angles of up to 10°, the best performance will be obtained by keeping all splay angles to less than 6°. Remember, the amplifiers for an ILA v2.0 system can drive up to 16 ILA boxes so it’s relatively inexpensive to add more speakers.

Finally, the "Auto Splay" function in Focus will provide a starting point – not a final solution for your array hang. Use the aiming points of the top and bottom boxes and manually fill in the rest so as to create either an arcuate or spiral array.
