"One of the main reasons for developing ILA v2 is to make true line array performance accessible in a far broader range of applications," QSC VP of marketing Gerry Tschetter says, explaining the underlying goal driving the product introduction. "Most line array systems today are manufactured for the touring sound market, which means that overall, system costs lie well beyond the means of many facilities that could gain direct benefits from the technology. By focusing on fixed installation needs with a molded enclosure and simplified rigging scheme, QSC has driven costs down while retaining the sound quality, coverage, and acoustic output of touring line array systems."
With ILA v2's SC28 system controller, setup by an expert using sophisticated acoustical measurement equipment isn't required. Offering simple preset recall processing built expressly to optimise ILA v2 and other QSC loudspeakers, the SC28 is easy to use, and offers audio quality so good that it's been included on major concert tours, says the company.
With power provided by QSC's RMX Series amplifiers, every ILA v2 system relies upon line array elements equipped with a pair of neodymium magnet, eight-inch diameter, low frequency drivers. While both of these woofers produce low frequencies, only one covers the midrange, thereby resulting in more uniform directivity in the crossover region. For high frequencies, a pair of 1.75-inch (voice coil diameter) neodymium compression drivers with titanium domes are mounted on a multiple aperture diffraction waveguide that provides extremely wide coverage (140ยบ). As a result, an ILA v2 system will rarely require additional side or centre-fill speakers, and solid stereo imaging is preserved across the listening area.
An upgraded subwoofer - the WL118-sw - is also offered with ILA v2 systems. A single 18-inch version of QSC's GP218-sw touring subwoofer, the WL118-sw offers impressive punch and low frequency extension. Using only three RMX 5050 amplifiers and a single RMX 2450HD, a pair of ILA v2 arrays incorporating six full-range line array enclosures and a pair of subwoofers can easily be powered with ample headroom to burn.
