User manual ELECTRO-VOICE X-LINE

[. . . ] X-LineTM System 1 T he Electro-Voice X-LineTM is a fully configurable linear sound reinforcement system. It is designed to allow one-person rigging while exhibiting both flat-front long-throw and curvedfront arc segment--or J-box--orientations. X-LineTM, Electro-Voice's realization of that classic J orientation, maximizes vertical-plane wave summing and eliminates the physical gaps between the rectangular enclosures at the J portion of the hang. Because such gaps separate the high-frequency radiating planes and result in non-coherent summing when the wavelengths are shorter than the spacings between rectangular enclosures, the X-LineTM simply provides cleaner sound. [. . . ] These dollies have sufficient clearance to allow the enclosures to travel with both the front and rear rigging hardware attached to the loudspeaker systems. This makes rigging set up and tear down extremely easy because the loudspeaker enclosures can be moved in blocks of four units. 18) illustrates the technique used to construct a loudspeaker array with enclosures transported on bottom dollies. The bottom dolly cannot be used with trapezoidal enclosures (Xvlt). A front dolly can be used with either the rectangular enclosures (Xvls or Xsub) or trapezoidal enclosures (Xvlt). The front dolly attaches to the front of a single loudspeaker system covering the grille and the enclosure front rigging track. This dolly allows the ease of moving one loudspeaker enclosure at a time; however, the rigging cannot remain attached to the enclosure during transport. 20) illustrates the technique used to construct a loudspeaker array with enclosures transported on front dollies. Because most arrays typically require more rectangular Xvls and Xsub systems than trapezoidal Xvlt systems, it would be common in large-scale touring situations for the rectangular boxes to be transported on bottom dollies and trapezoidal boxes to be transported on front dollies. Thus, both rigging techniques may be employed in the same array. Adjusting Vertical Angles of Enclosures The vertical angle of an enclosure may be adjusted relative to the enclosure immediately above by the choice of the attachment position of the Xvsl front linking straps in the enclosure track. The locating holes in the enclosure rigging track are spaced 1. 00 inches apart. Moving the attachment position one hole results in a 2° change in the enclosure vertical angle. A 1° angle adjustment is possible, however. The chain on the Xvsl linking strap is secured to the fittings on each end with a pin through a hole on each fitting. Note that there are two holes on each fitting labeled "A" and "B". These two holes offer two attachment points that change the length of the linking strap assembly. When the chain is connected in the "B-B" position, the Xvsl linking strap is 0. 500 inches longer than when connected in the "A-A" position. This 0. 500-inch change in length results in a 1° angle adjustment. Thus, by adjusting the length of the Xvsl linking straps and their attachment position on the enclosure front track, the relative angles between boxes can be adjusted in 1° increments. When used with the "A-A" length, even-numbered angles result (0°, 2°, 4°, 6°, etc. ) when changing the attachment position of the linking strap along the track, while odd-numbered angles result (1°, 3°, 5°, 7°, etc. ) when used with the "B-B" length. When planning angle adjustments between boxes, the shape of the enclosure must be taken into account. Two rectangular enclosures (either Xvls or Xsub) can be pulled up tight with their sides parallel, leaving a 0° relative angle between the enclosures (that is, both are facing straight ahead).
