[. . . ] Xb X-ArrayTM Bass System · Unprecedented acoustic output in a small, lightweight package · Ring-Mode Decoupling (RMD)TM provides accurate transient detail · EVX-180B woofers · Unique rear-hinge rigging · Enclosure shell and rigging identical to all of the full-size X-ArrayTM systems Description The X-ArrayTM product line represents important advancements in concert-sound reinforcement technology. The design goals called for the highest acoustic output capability with the highest fidelity in lightweight, compact enclosures that were easy to array. The development began with a clean sheet of paper and took an integrated approach. The individual loudspeaker drivers, horns, enclosures, rigging hardware and system configurations were designed from the ground up specifically for this high-performance application. [. . . ] Note that, when two Xb systems are jumped from one to another via the input/output connections, the amplifier home run cable will have two LF drivers on Pins 2 (for a 4-ohm load) and two LF drivers on Pins 1 (for a 4-ohm load). Flying the X-ArrayTM Systems The X-ArrayTM loudspeaker systems all utilize the same rigging hardware and have the same structural strength ratings. Thus, different systems may be mixed in an array to achieve the best acoustic results. The rigging system allows for the smallest possible spacing between adjacent enclosures, and utilizes quick-release rigging fittings for fast installation and tear down. When flown, the X-ArrayTM enclosures are linked together by two removable hinges on the rear of the enclosures at the top and bottom. This arrangement enables the enclosures to pivot vertically from the rear corners. The relative vertical angles between adjacent enclosures is adjustable and set by two removable rigging straps on the front of the enclosures at the top and bottom. Both the rear rigging hinges and the front rigging straps are installed when enclosures are sitting on top of one another. For ease of installation of the hinges and straps, the enclosures self align using feet and cups mounted on the top and bottom of the enclosures. The relative horizontal angle between adjacent columns of loudspeakers is set by adjustable grids at the top of the array (or by custom-building attachment supports in permanent-installation applications where grids are not used). The removable proprietary rear rigging hinges utilize all-steel construction, and are secured into a proprietary track assembly on the enclosure (similar to the heavy-duty aircraft L-track). The aluminum track is extruded as a single-piece track/angle-bracket aluminum assembly and ties into the top, bottom and rear of the enclosure. Metal bars inside the enclosure tie the top and bottom track/angle-bracket assemblies together, minimizing the load applied to the wooden enclosure. The rear extrusion will accommodate the New Haven 32102-2 aircraft-type double-stud locking fitting instead of the hinge for applications requiring a lower strength rating. The removable, front strap assemblies utilize all-steel standard New Haven 32102-2 aircraft-type double-stud locking fittings and wire-rope and are secured into another proprietary track similar to the heavy-duty aircraft L-track. The track is extruded as a single-piece track/angle-bracket assembly that ties into the front and side of the enclosure. The track/angle-bracket assembly extends from the top to the bottom of the enclosure, eliminating the load applied to the wooden enclosure. Rigging Accessories: Grid: This ATM Fly-WareTM "T"­shaped, all-steel-construction grid was specifically designed as a single column of X-ArrayTM systems. Multiple grids can be linked together with couplers on front and back retractable arms, the position of which sets the splay angle between adjacent columns. Wilmington Ave. , Carson, CA 90810 USA, 310/834-5914 Xrhg Grid Hinge: Two Xrhg grid rigging hinges are used to attach the rear of the top enclosure in a column to the rear of an X-ArrayTM compatible grid. Each hinge consists of two precision-machined steel riggingtrack fittings connected by an alloy-steel chain. Electro-Voice, 600 Cecil St. , Buchanan, MI 49107 USA, 616/695-6831 or 800/234-6831 Xrhp Pickup Hinge: Two Xrhp pickup rigging hinges are used to create custom rigging assemblies to attach to the rear of the top enclosure in a column when an ATM grid is not used.
