[. . . ] Center the main body of the fitting over one of the track cutouts, with the feet located on either side (i. e. , the feet positioned directly under the teeth of the track). The round protrusion on the bottom of the fitting should lock into the round cutout in the track, with the locking ring retracting to its normal position, allowing the safety pin to reappear and extend over the locking ring. If the fitting does not lock into the track, nudge it along the track and wiggle as necessary until it settles into position. If the outer locking ring does not fully re-tract, push the ring towards the track until the safety pin reappears and extends over the locking ring. When locked, the fitting will be immovable in the track and the locking ring of the fitting may not be lifted. ALWAYS CHECK TO MAKE SURE THAT THE DOUBLE-STUD FITTING IS SECURELY LOCKED INTO THE TRACK, AND THAT THE SAFETY PIN IS EXTENDED OVER THE LOCKING RING BEFORE LIFTING ANY LOUDSPEAKER ENCLOSURE OVERHEAD. ELECTRO-VOICE® X-Line TM Rigging Manual 18 2. X-Line Rigging and Flying Techniques 2. 1 Array Considerations The X-Line loudspeaker systems have been specifically designed to construct acoustic linearrays. Line-array systems typically consist of independent columns of loudspeaker systems. The most common implementation would be a stereo sound reinforcement system with two columns (left and right). Additional columns of loudspeakers are sometimes added to cover different seating sections of a venue seating areas that wrap around the side or back of a stage, for example. Vertical line arrays typically consist of several Xvls 90°H x 5°V systems at the top, followed by several Xvlt 120°H x 8. 5°V systems below. With A-B length, in between angles are achievable (0. 5°, 2. 5°, 4. 5°, etc. ). When planning angle adjustments between boxes, the shape of the enclosure must be taken into account. Two rectangular enclosures (Xvls, Xsub, Xfil) can be pulled up tight with their sides parallel, a 0° relative aiming angle exists between the enclosures (i. e. , both are facing straight ahead and the sound from both is aimed straight ahead). When two trapezoidal enclosures (Xvlt only) are pulled up tight with their sides parallel, a 5° relative aiming angle exists between the enclosures (because the enclosure shape is a 5° wedge, the sound from both is aimed 5° apart). When a trapezoidal enclosure (Xvlt) and rectangular enclosure (Xvls, Xsub, Xfil1 or Xfil2) are pulled up tight with their sides parallel, a 2. 5° relative aiming angle exists between the enclosures. Figure 8 shows all of the possible combinations of rigging attachment locations and linking strap lengths. When designing an array using the X-Line modeling software, the program will automatically tell you what each front strap length is required (A-A, A-B or B-B) and at what position on the rigging they should be attached for each enclosure.

Figure 8: Enclosure Vertical Angle Adjustments ELECTRO-VOICE® X-Line TM Rigging Manual 20 In this document and in the software modeling program, the front rigging fitting attachment locations are denoted by the number of holes showing in the rigging track once a rigging strap is installed. On each side of the enclosures at the front, there is a pin in the middle of the rigging track that is used to secure the Front Dollies to the enclosures. When two enclosures are linked together so that they are tight packed with the sides of the enclosures parallel, the rigging fittings are installed near the middle of the rigging track in the last available rigging cutout next to the dolly pins. [. . . ] Grid Assemblies: Prior to each use, inspect the grid assembly and associated hardware for any cracks, deformations, broken welds, corrosion, missing or damaged components that could reduce the grid assembly strength. Never exceed the limitations or maximum recommended load intended for grid assembly design. Never exceed the limitations or maximum recommended load for the grid assemblies. Chain Hoists: Prior to each use, inspect the chain hoist and associated hardware (including motor, if applicable) for any cracks, deformation. [. . . ]
