User manual FENDER SPA-7500

[. . . ] In fact, many of the world's best sounding electric musical instruments and sound reinforcement equipment proudly wear the Fender name. Whether you need a simple box top powered mixer for your Saturday afternoon jam, or a professional full-size concert system, Fender has the sound reinforcement equipment to meet your needs. Wishing you years of enjoyment and a heartfelt thank you, Bill Schultz Bill Schultz Chairman Fender Musical Instruments Corporation 2 TOUR SERIES 215s / 215sc PROFESSIONAL SUBWOOFER LOUDSPEAKERS INTRODUCTION 13-Ply Baltic Birch Cabinet 1600W Program Power Handling 35 Hz to 170 Hz Frequency Response 101 dB Sensitivity @ 1W / 1m Two 15" Woofers with 4" Voice Coils and 110 Ounce Magnets 4-pole SpeakonTM Connectors and High Current 1/4" Phone Jacks Thank you for purchasing a Tour Series 215s or 215sc Professional Subwoofer from Fender Pro Audio. [. . . ] Designed for the most demanding concert sound and sound contracting requirements, the cabinet's multiple cavities and internal wood bracing helps eliminate side wall movement. This design results in low distortion, very high power handling and very high SPL output. Likewise, large ports on the 215s and 215sc cabinets prevent compression at high SPL due to large exit velocities. After moisture sealing, the 215s cabinet is painted with a environmentally friendly tough black finish for longer life and lasting looks. The 215sc is covered in a rugged black carpet with the addition of metal corners and feet. Also, a pole mount adapter is available for placing a mid or high range enclosure over the 215s or 215sc. -Only use Fender Mounting Pole (P/N 071-1359000) to support the full range cabinets. 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 The two 4-Pole SpeakonTM connectors and the two 1/4" phone jacks are wired in full parallel so that any one of the connectors may be used as an input and the other connectors as an output to another subwoofer. This allows the multiple, cabinets to be "daisy chained", eliminating the need for several long runs of speaker cable. The third consideration is convenience and the visual aspect of the speaker array. For temporary installations, the subwoofer can be used as a support for a mid/high pack mounted either directly on top of the subwoofer or supported by the optional pole mount assembly (Fender P/N 071-1359-000) and using the subwoofer as a base. In permanent installations, the 215s/215sc, for example, can be placed under a stage or table. For each particular situation, a compromise among these three factors should yield the best solution possible. USING THE 215s/215sc IN A SYSTEM The 215s / 215sc is designed to augment the low frequency performance of the main P. A. By reproducing very high levels of the low bass frequencies, the 215s / 215sc relieve the smaller main speakers from having to supply this energy. In order to split frequencies and send certain frequencies to one type of speaker and other frequencies to another type, a line-level electronic crossover, such as a Fender PCN-2 or PCN-4, is required. Two different configurations are shown on pages 5 and 6, demonstrating how easy it is to add a subwoofer to a system. Figure 3, on page 7, shows a more extensive configuration for those set-ups requiring additional power. 4 CROSSOVER SUGGESTIONS After the speaker system has been placed, the crossover point needs to be set for maximum benefit. While the 15" drivers in the 215s/215sc are fully capable of accurately reproducing frequencies above 350 Hz, the bandpass enclosure has been designed to acoustically roll off frequencies above 170 Hz. [. . . ] Thus, the crossover point should be set lower than 130 Hz to ensure that all frequencies are reproduced. Setting the crossover point too low (below 80 Hz) will not take full advantage of the subwoofer because it places too high of a demand on the mid/high packs. For these reasons, a crossover point of ranging between 80 and 130 Hz is recommended depending upon the placement of the speakers. [. . . ]
