User manual FENDER 2912C

[. . . ] The 2912(c) /2915(c) is a professional, full-range, twoway, compact loudspeaker designed for the most demanding concert sound and sound contracting requirements. With a scientifically derived trapezoidal shape and equipped with fly-points for use with the Fender RigSafeTM rigging and flying hardware (except "c" versions), the speakers are designed for use as a single unit or as part of a larger loudspeaker array. The RigSafe system is compatible with both the JBL S. A. F. E. TM and the ATM FlywareTM components. [. . . ] (See the section on "Horn Inserts" for more information. ) 2912 2912 2912 A "tight-pack" array requiring a 60º horizonal dispersion pattern 4 A second consideration is for feedback and bass performance. If the speaker is placed near a large, flat wall, the bass output will be increased by approximately 6 dB. Placing the speaker near a wall can cause feedback. If this occurs, the speaker must be moved. In general, placing speakers near a wall works best if the sources feeding the speaker are line level items. A third consideration is to what degree the speaker should be "heard and not seen", especially in permanent installations. Flying (hanging the speakers from the ceiling) is one option whereby the 2912 / 2915 can be integrated with a 118s subwoofer. In this configuration, the speakers can be arranged in any array of up to three rows (tiers), loose or tight pack, with or without downward angling (splaying). HORN INSERTS To change the dispersion pattern from 90º to 60º, first remove the grille from the speaker. Using a small screw driver, gently pry the grille away from the top and bottom cleat. Next, gently pull outward at the center of the grille; it should bend and pull out from under the sides. If your insert has a plug on it, you may wish to remove it for easier installation. To do so, carefully cut it off with a razor blade. To attach the two horn inserts, first place the wider end of the insert under the front lip of the horn. Next, guide the smaller end of the insert under the ribs near the throat of the horn. The insert is secured in place by the 3 ridges. 2915 2915 118s Installing the 2912(c) / 2915(c) horn insert Reinstall the grille by placing one side of the grille under the side cleat, then gripping the grille on the top and bottom, bend the other end under the cleat at the opposite end of the cabinet. With the inserts installed, the horizontal coverage angle is reduced to 60º. [. . . ] An example of this configuration is shown on the next page. It is strongly recommended that a fourth-order "Linkwitz-Riley" or a digital FIR fourth-order active crossover be used. The crossover frequency, for both the 2912(c) / 2915(c), should be set at approximately 2000 Hz. [. . . ]
