The JBL PRX535 is a self-powered, lightweight 3-way loudspeaker system capable of delivering a very high level of performance. The PRX535 is comprised of a 15" 265F Differential Drive woofer, a 6-1/2" 195H horn-loaded 90° by 50° mid-range, and a 2408H 1-1/2" annular polymer diaphragm, neodymium compression driver mounted to a 90° by 50° horn—all driven by a multichannel Crown International Class-D digital power amplifier. A propriety DSP chip is at the core of a fully featured input section, providing user selectable system EQ, protection, input sensitivity selection, cross-over functionality, dynamic limiting, and discrete component optimization.
The enclosure is constructed of quality plywood and coated in JBL's rugged DuraFlex finish. Durable polypropylene end-caps add extra protection for the cabinet. An integrated polemount on the bottom endcap enables easy deployment. The CNC machined steel grille wraps around the sides of the enclosure so there are no protruding lips on the front of the box to create acoustical interference. The grille is also lined with an acoustically transparent foam to provide additional driver protection.
The amplifier input panel offers XLR or 1/4" jack compatibility and a sensitivity switch provides extra flexibility, making it possible to connect literally any sound source without using a mixer. Signal present and overload lights indicate the system status and assist in setting the optimum level, via the level control knob.
