ll8L Filter Cards ofter an extensive menu of pre-set features as weil as user selectable functions, setting new standards for system adapt­ bility with limiters which can be adjusted to match amplifier gain and with connections for sub­ woofers in vented enclosures or Tripie Chamber Bandpass (TCB) enclosures. The Sound Power Controller has been designed specifically to control sound, not to process it. The Sound Power Series trans­ ducers do not need processing, which would unavoidably impose its own colorations and sonic artifacts on the sound. The Sound Power Series is dedicated to the faithful reproduction of the original signal . Unlike typical heavy-handed limiters which cut oft musical transients vital to the liveness of he JBL Sound Power Systems approach pro­ vides the user with a wide selection of high quality total sound system solutions to fulfil virtually any need in SR, PA and MI applications. Each Sound Power System consists of a perfectly matched combination of selected Sound Fbwer loudspeakers and MPA power amplifier components totally integrated by the Sound Power Controller configured with pre-set system-specific dedicated filter cards. The Sound Power systems solution removes the guesswork in selecting speakers, crossovers, power amplifiers and, equally important, in the combining of these components into perfectly matched systems with optimum performance.

User access is restricted to non­ critical parts and functions, elimi­ nating a major source of potential error and damage. Because power line voltage in the field can vary wildly, the JBL Sound Power Controller is de­ signed with a switching power supply which can handle extreme swings from an unstable voltage supply and will function with a line voltage from 100-240 volt. To assist the user in optimizing the application of a chosen system, JBL ofters the CADPZM and SRDSTIVi computer software programs. Based on the physical details of the venue and the proposed Sound Power System configuration, SRDSTfv1 ofters a quick estimate of basic perfor­ mance parameters, while CADP2™ provides a more detailed analysis -.. ." :. : : : : ,.~ ..

At the same time, the Controller will allow the user all the flexibility required to adapt the system to any specific situation. The Controller consists of a main unit plus a dedicated pre-set system filter card configured to match the specified Sound Power System of your choice. The JBL Sound Power Controller System the sound, the limiters in the JBL Sound Power Controller preserve the integrity of the original signal, based on true RMS detection, operating as a "gain control'; predicting the heat generated in the speaker. The JBL Sound Power Controller protects the speaker from overheating, while leaving intact the crucial musical transi­ ents which JBL transducers handle with the greatest of ease. The ergonomics and operation of the JBL Sound Power Controller have been refined during endless hours of hands-on, real world field 1 I 10 I ;:', and prediction of system per­ formance. The program data bases include Sound Power Systems and the individual speakers in the Sound Power Series. The bottom line: The Sound Power Systems approach makes life easier for the user by removing guesswork fram the design and selection of sound systems. With JBL's dedicated software, the performance of a given system can be evaluated in detail, for fast, easy and reliable systems solutions. . • I 1 .. TOURING arge scale sound rein­ forcemellt is a highly specialised field involving the consistent and reliable delivery of tremendous sound pressure levels into huge and often irregular spaces. Serious professionals demand serious professional systems that can perform consistently under extreme conditions. The JBL Sound Power Touring Series offers a simple and efficient solution to the complex problems of PA for major events with a new horn/compression driver combina­ tion, more efficient powerful woofers and cutting edge JBL driver technology including flat wire coils, Symmetrical Field Geometry (SFG™), Vented Gap Cooling (VGCM), titanium diaphragm compression drivers and Bi­ Radial™ horns. The resulting drivers demall­ ded similar breakthroughs in cross­ over technology and enclosure build, enabling the JBL Sound Power Touring Series to reach new levels of musical performance efficiency, compactness and reliability. L STRUCTURAllNTEGRITY The superior strength and rigidity of the JBL Sound Power Touring cabinets are achieved using high­ density 21 mm 13-ply Finnish birch hardwood construction and comprehensive internal bracing. The cabinets are attractively finished in a durable black acid­ hardened paint that resists scuffing and chipping during transport, set-up and rigging. Every JBL Sound Power Touring loudspeaker sports a 3 removable grille of 2 mm per­ forated steel lined witll open cell reticulated foam to protect against moisture damage and dust. RIGGING The integrated aluminum corner­ mounted hanging system protects cabinets during transport, while providing unique flexibility and strength during installation. The integral mounting hard­ ware made from a special an­ nealed aluminum alloy surpasses the strictest safety standards. The mounting system allows convenient stacking or clustering and the enclosurelbrace combination can handle in excess of 10 tons. You'lI bring the roof down, long before these reliable braces give way. In clusters the integral hanging points create a "unified front;' effec­ tivelya single, continuous baffle with no gaps between the cabi­ nets, enhancing overall system performance. ACCESSORIES The comprehensive range of JB L electronics, accessories and cabling options enhances the total system flexibility that has been a primary design goal for the JBL Sound Power Touring Series. For signal interface JBL employs specialised Neutrik connectors, long championed by JBL for their long-term reliability, improved current characteristics and absolutely air-tight sockets.
