[. . . ] The Xf is an active far field, two-way, MB/HF loudspeaker system with a 40° H x 20° V coverage pattern utilizing the full-size X-ArrayTM enclosure shell. The high-frequency and mid-bass sections are horn loaded with two drivers in each frequency band, and the high-frequency horn/driver combination is mounted coaxially inside the mid-bass horn. The horns and drivers were designed as part of the Xf development and represent a step forward in state-of-the-art loudspeaker design in terms of high acoustic output with low distortion and low power compression. Electro-Voice engineers developed a new technology dubbed Ring-Mode Decoupling (RMDTM) to substantially im-
prove clarity and intelligibility by reducing both linear and nonlinear resonance modes that color the sound. [. . . ] For basic applications, the Electro-Voice Dx38 2-in/4-out controller is recommended. For more sophisticated applications, the Klark
Xf Two-Way, MB/HF System
Xf T wo-Way, MB/HF System
Teknik DN8000 2-in/5-out controller is recommended. Linkwitz-Riley crossover filters with a minimum slope of 24 dB per octave at 125 Hz and 1, 760 Hz are recommended. Both the Dx38 and the DN8000 offer appropriate filtering, equalization and signal delay capabilities to provide optimum performance of the X-ArrayTM loudspeaker systems. Digital parameter settings for both controllers are avaialble upon request. Electrical Connection and System Wiring Two paralleled Neutrik 8-pin Speakon® connectors are used for electrical connection to the Xf loudspeakers with the following pin assignments: HF: Pins 4 Paralleled MB: Pins 3 Paralleled The Xf wiring diagram is shown in Figure 7. Since the connectors are paralleled, it does not matter which connector is used as the input or output when paralleling Xf systems. Although Pins 1 and 2 are not used by the Xf systems, they are paralleled on the input panel. This allows an X-ArrayTM bass box (like the Xb which uses Pins 1 and 2, but not Pins 3 and 4) to be paralleled with an Xf, allowing all eight conductors to be used with a single cable run to the amplifiers. Note that, when two Xf systems are jumped from one to another via the input/ output connections, the amplifier homerun cable will have four high-frequency drivers on Pins 4 (for a 4-ohm load) and four mid-bass drivers on Pins 3 (for a 4ohm load). Flying the X-ArrayTM Systems The X-ArrayTM loudspeaker systems all utilize the same rigging hardware and have the same structural strength ratings. The drivers may be accessed as follows: HF: First remove the grille, then remove the screws securing the front flange of the highfrequency horn. 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. Each hinge consists of one precision-machined steel rigging-track fitting
with an alloy-steel chain. Electro-Voice, 600 Cecil St. , Buchanan, MI 49107 USA, 616/695-6831 or 800/234-6831 Xrhl Linking Hinge: Two Xrhl linking rigging hinges are used to link two enclosures together at the rear. Each hinge consists of two precision-machined steel rigging-track fittings connected by a heavy-duty steel hinge. Electro-Voice, 600 Cecil St. , Buchanan, MI 49107 USA, 616/695-6831 or 800/234-6831 Xrsl Long Rigging Steel Straps: Two Xrsl long rigging straps are used at the front of two enclosures to adjust their relative vertical angles. The Xrsl may also be used to attach the front of the top enclosure to the ATM grid when upward angles are not required. [. . . ] Exclusions and Limitations: The Limited Warranty does not apply to: (a) exterior finish or appearance; (b)
certain specific items described in the individual product-line statement(s) below, or in the individual product data sheet or owner's manual; (c) malfunction resulting from use or operation of the product other than as specified in the product data sheet or owner's manual; (d) malfunction resulting from misuse or abuse of the product; or (e) malfunction occurring at any time after repairs have been made to the product by anyone other than Electro-Voice Service or any of its authorized service representatives. Obtaining Warranty Service: To obtain warranty service, a customer must deliver the product, prepaid, to ElectroVoice Service or any of its authorized service representatives together with proof of purchase of the product in the form of a bill of sale or receipted invoice. A list of authorized service representatives is available from Electro-Voice Service at 600 Cecil Street, Buchanan, MI 49107 (800/234-6831 or fax 616/ 695-4743). Incidental and Consequential Damages Excluded: Product repair or replacement and return to the customer are the only remedies provided to the customer. [. . . ]
