ILA Series v2

Installation Line Array

Installed Sound

Most line array systems are designed for touring applications which require extreme ruggedization and expensive suspension hardware. By focusing on installation applications QSC drove cost out of the

ILA System while retaining the performance of high-end touring line array systems. ILA System v2 takes this concept and builds on it by offering a complete and accessible solution consisting of processing, amplification, line array, subwoofer and suspension accessories.

WL2082-i

Each Installation Line Array element uses a pair of high-power, neodymium magnet, 8" diameter low-frequency drivers. For high frequencies, a pair of

1.75" (voice coil diameter) neodymium compression drivers with titanium domes are mounted on a patented* 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 entire listening area.

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.

WL118-sw Subwoofer

The WL118-sw is a single 18" version of the popular

WideLine-10 touring, dual 18" subwoofer. ILA subs may be suspended at the top of an ILA array using the standard FB2082-i array frame. When trim height is limited, the ILA sub may be suspended behind the array using the available EB2082-i extension bar.

GP118-sw Subwoofer

The GP118-sw omits the ILA compatible suspension hardware but retains the identical acoustical performance of the WL118-sw at a lower cost. Each

GP118-sw includes a total of eight (8) threaded

M10 inserts for single box suspension in permanent installations. In ground-supported applications, multiple units can be stacked vertically utilizing the interlocking feet and recess features machined into the enclosures top panel. Also included on the GP version is a screw-in (M20) pole mount to provide flexibility as a “Sub-Sat” system when used with full-range pole mount speakers such as K or KW.

Processing

The SC28 is a 2 input, 8 output digital system controller containing pre-programmed tunings for the

ILA and other QSC loudspeaker systems. In addition to the preset tunings, the SC28 offers user-adjustable equalization and delay. Simple to operate yet uncompromised in audio quality, the SC28 uses

48 kHz, 24-bit A/D and D/A conversion with 32-bit, floating point DSP for wide dynamic range and low distortion.

EASE Focus Software

This free software may be downloaded from the support section of the QSC website and is available for ILA,

WideLine-10 and WideLine-8.

EASE Focus is a software tool that aids in system planning and deployment.

Functions performed include:

• Calculating the number of enclosures required for a given space.

• Determining optimum splay angles

between enclosures.

• Calculating the angle to set the array grid in a single (variable) pick-point or fixed suspension point application.

• Predicting the acoustical response and SPL throughout the venue.
