[. . . ] After moisture sealing, the 2912 / 2915 cabinets are painted with an environmentally friendly tough black finish for long life and lasting looks. The 2912c / 2915c are covered in a rugged black carpet with the addition of metal corners and feet. These speakers are ideal for use as a two-way system or as the mid / high pack in a three-way set-up incorporating a 118s(c) or 215s(c) subwoofer loudspeaker system. CAUTION: Almost all speakers produce strong magnetic fields which may interfere with the normal operation of nearby electronic devices, including televisions and computer video monitors. [. . . ] To reduce or eliminate interference, increase the distance between this product and other nearby electronic devices. 3 CONNECTIONS In normal operation (using the passive internal crossover), the 1/4" jacks and the Speakon TM Connectors are wired in parallel allowing any one of the connectors to be used as an input and any other as an output. This allows "daisy chaining" of multiple loudspeakers, eliminating the need for several long, cumbersome runs of speaker cable. During normal mode, the connections are as follows: Polarity Positive (+) Negative (-) Phone Jack Tip Sleeve SpeakonTM 1+ and/or 2+ 1- and/or 2- SETUP SUGGESTIONS The placement of any speaker can dramatically affect its sound. Thus, there are several considerations to review when placing loudspeakers. If the speaker will be used as a single unit, as part of a pair, or as part of a group of widely spaced enclosures, then maximum horizontal coverage will be desired. The horn in this configuration has a horizontal coverage angle of 90º and a vertical coverage of 40º. When the switch on the back of the speaker is in the bi-amp mode, the internal crossover and high frequency attenuator are disabled. Thus, an external crossover must be used with the speaker and two channels of power amplification will be required: one for the low frequencies and another for the high frequencies. In bi-amp mode, the connections are as follows: Phone Jacks Frequency Lows Lows Highs Highs Polarity Positive (+) Negative (-) Positive (+) Negative (-) Left N/A N/A Tip Sleeve Right Tip Sleeve N/A N/A Speakon 1+ 12+ 2- 2915 Stage 2915 Audience Two speakers arranged as a mono or stereo pair requiring maximum horizontal coverage 30º 2912 IMPORTANT: If the crossover switch is set to external, DO NOT plug a full range signal into the High Frequency input. Doing so will destroy the compression driver. 2912 Two speakers in a "loose pack" array requiring maximum horizontal coverage If the speaker is part of a tightly packed array (see figure below), the coverage pattern should be modified to reduce overlapping radiating patterns of multiple drivers. When both inserts are installed, a 60º coverage pattern is achieved. This is useful in multi-cabinet tight pack arrays where a narrower consistent coverage pattern is required. With the horn inserts removed, a 90º coverage pattern is attained offering a wider horizontal dispersion pattern. 2912 2912 118s Flying speakers with the Fender RIGSAFETM system The Fender RigSafeTM system is designed into both speaker cabinets models to safely accommodate such practices. This system is compatible with both the JBL S. A. F. E. TM and the ATM FlywareTM rigging systems. Nonetheless, flying loudspeakers above crowds is dangerous and should only be undertaken by experienced and insured riggers. For more information on safe rigging practices, please refer to the "Flying with Fender RigSafe TM" brochure (p/n 049646) or contact ATM FlyWare at (310) 834-5914. 5 NORMAL vs. BI-AMP OPERATION Hours of testing and listening are used to determine the crossover point and filter slopes for each speaker. This information is then used to design the built-in passive crossover. For versatility and increased headroom, some users may wish to use an active electronic crossover / processor, such as the Fender PCN-2 or PCN-4, with the system. [. . . ] For versatility and increased headroom, some users may wish to use an active electronic crossover / processor, such as the Fender PCN-2 or PCN-4, with the system. This electronic crossover or processor will take the place of the internal crossover of the speaker system. The "Normal / BiAmp" switch on the back of the cabinet must be set to the "Bi-Amp" position. For those situations requiring a subwoofer, the 2912(c) / 2915(c) can still be amplified if a three-way electronic crossover is used. [. . . ]
