SLS Loudspeakers will debut the RLA/3 ribbon line array speakersystem at NSCA 2004, Booth #2503. The system is configured usingmultiple lightweight and compact LS6500 modules that use thecompany’s unique ribbon driver technology. The RLA/3 is targetedtoward corporate, sanctuary and club venues where placing line arraysare challenged by either size or budget constraints.,/P>

“The RLA/3 is basically a splayable version of our unique andpopular LS8695 Columnar Line Array, which is now being used byNBC’s The Today Show,” stated SLS’ director ofmarketing Jeff Lowry. “The RLA/3 shares many of the same featuresand components of the LS8695 and arrives in the marketplace at under$800 per module, making it one of the most cost-effective line arraysolutions available to date.”

The LS6500, the basis for the RLA/3 line array, features a 100-wattRMS, 6.5-inch woofer and an SLS PRD500 5-inch planar ribbon driver in acompact bass-reflex trapezoid enclosure. The modules offer a frequencyresponse of 80 to 20k Hz and horizontal coverage of 110 degrees. All ofthe necessary rigging is included.

Equipped with a PRD500 planar ribbon driver that has extremely highoutput evenly distributed over its entire radiating surface, the RLA/3presents a coherent wave front that is ideal for energy transfer. Thegeometry of the array enables a virtually continuous line source to becreated. System performance can be accurately predicted using theSLS’ LASS CAD modeling program.

The low-frequency section provides a sensitivity spec of 94 dB(1W/1m) with a nominal impedance of 8 ohms. The system handles 100watts, yielding a continuous SPL of 114 dB with a peak performancerating of 120 dB. The high-frequency section delivers 101 dB (1W/1m)with nominal impedance of 8 ohms and handles 50 watts RMS with a SPL of118 dB reaching 127dB peaks.

Weighing 20 pounds and enclosed in a 13-ply Baltic-birch, blackNeverMar enclosure, the RLA/3 measures 7.25x14x10 (HxWxD) inches.
