    Description

    18" subwoofer - for use with WL2082-i installation line array, may be ground-stacked or suspended with WL2082-i, integral array hardware, available in black.

    Specifications

    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.
