Prx618s-xlf

* Maximum SPL 133 db peak * 460mm (18 in) Differential Drive dual voice-coil and magnetic gap, neodymium woofer * 1000 Watt (2 x 500 watt) Class-D, Crown digital amplifier * DSP input section with dbx Type IV™ limiter circuit, crossover, dynamic limiting, component optimization, selectable system EQ * Professional XLR line and ¼" Mic/Instrument inputs, with loop through * Obsidian DuraFlex coated plywood construction * Top panel M20 pole mount socket for sub/satellite configuration * Large die-cast aluminum handle bar with a fine tuned ergonomic rubber grip for maximum comfort BL PRX618S-XLF extended low frequency subwoofer was designed and engineered to provide sub bass frequencies with accuracy and power. Used as a single sub in a sub/sat system or in multiples as part of a scalable, large format sound reinforcement system, the PRX618SXLF performs with extreme efficiency and control. The subs are stackable and light-weight ensuring quick set-ups and tear-downs. And due to their rugged construction are perfect for AV rental inventories. With a pole receptacle (that accepts a SS4-BK or SS4-BK24) on the top panel and integrated stereo pass-thru this is the most powerful low-frequency complement to the PRX full-range systems. The addition of a polarity reverse option further enables system optimization. The JBL PRX 618S-XLF is a high performance self-powered subwoofer system. The PRX-618S-XLF is comprised of a powerful 2268FF Differential Drive dual voice-coil and magnetic gap, neodymium woofer driven by a 1000 Watt (dual 500 watt) Crown Class-D power amplifier. Dual-Bridge Technology directly links discrete amplifier channel outputs to each voice coil in the Differential Drive woofer. Electrical power transfer to the transducer is optimized for more power performance. A proprietary DSP chip is at the core of a fully featured input section, providing user selectable cross-over functionality, polarity optimization, protection, dynamic limiting and discrete component optimization. The amplifier input panel offers stereo inputs with XLR or ¼ inch jack compatibility. A user selectable crossover ensures a smooth transition to full-range system connected to the stereo outputs. Signal present and limiter lights indicate the system status and assist in setting the optimum level, via the level control knob.
