78058_JBL_PRX612M.qxd 5/27/10 1:06 PM Page 1 Professional Series PRX612M Self Powered 12", Two-Way, Bass-Reflex Features: 䉴 Maximum SPL 134 dB peak 䉴 Dual purpose enclosure for both front-of house and floor monitor applications 䉴 Eight M10 fly points for horizontal or vertical suspension. One M10 pull-back point. 䉴 Optimized EQ for monitor or front-ofhouse applications 䉴 305 mm (12 in) Differential Drive® dual voice-coil and magnetic gap, neodymium woofer 䉴 37.5 mm (1.5 in) annular polymer diaphragm, neodymium, compression driver 䉴 1000 Watt (Dual 500 watt) Class-D, Crown® amplifier. 䉴 DSP input section, crossover, dynamic limiting, component optimization, selectable system EQ 䉴 Professional XLR line and ¼ in Mic/Instrument inputs, with loop-through. 䉴 Dual socket pole mount with (angle) down-tilt. Application: PRX612M is the most compact and versatile speaker in the PRX600 Series. It has been designed to deliver maximum performance for its weight and size as both a stage monitor and a front-of-house main PA. Two user selectable EQ settings are provided to optimize the system for either application. With a dual socket pole mount, the PRX612M is a perfect match with a PRX618S subwoofer, offering a high performance self-powered sub/sat system. The PRX615M is comprised of a 305 mm (12 in) 262F-1 Differential Drive® woofer, a 2408H-1, 37.5 mm (1.5 in) annular polymer diaphragm, neodymium compression driver mounted to a 90° by 50° horn, all driven by 1000 watt (dual 500 watt) Crown® Class-D digital power amplifier. A proprietary 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 amplifier input panel offers XLR or ¼ in 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 limiter lights indicate the system status and assist in setting the optimum level, via the level control knob. All PRX600 cabinets are built from a combination of 25 mm (on the top and bottom for added rigidity) and 18 mm, strong, lightweight poplar plywood made structurally sound with tongue and groove joints. All PRX600 Series cabinets are protected by JBL’s tour proven DuraFlex™ finish. Grilles are made from dent-resistant 16 gauge steel and handles are made from lightweight, glass-filled nylon for added strength and durability. All M10 suspension points are constructed from 14 gauge steel and have been tested with a yield-strength of 1000 lbs. each.

Some materials, production methods and design refinements are introduced into existing products without notice as a routine expression of that philosophy. For this reason, any current JBL product may differ in some respect from its published description, but will always equal or exceed the original design specifications unless otherwise stated. 78058_JBL_PRX612M.qxd 5/27/10 1:06 PM Page 2 䉴 PRX612M 12" Self Powered Two-Way, Bass-Reflex Frequency Response INPUT MAIN MIC LEVEL +4 dB 110 100 -10 dB MONITOR PRX612M LIMITER SIGNAL l SPL (dB) EQ POWER LINE 90 80 LINE SELECT IN 70 20 100 1000 10000 20000 Frequency (Hz) JBL PROFESSIONAL Northridge, CA.
