SPEAKER SR1530 SR1530 3-Way Active Sound Reinforcement Speaker System  The SR1530 is a high-output, horn-loaded, 3- way, wide dispersion, active sound reinforcement speaker system. The combination of active on-board electronics and high-precision transducers allows the SR1530 to generate high output levels with complete clarity and high resolution.  The transducers developed for the SR1530 fea- ture several innovations specifically designed for this speaker system. The SR1530 is the first speaker in its class to feature a horn-loaded mid-frequency transducer. By designing a one piece 90° x 40° horn, which includes both the mid and high-frequency sections, the SR1530 takes advantage of several performance benefits. First the 6-inch mid-range's basket assembly is designed as part of the horn assembly. It is also designed to function as an optimized compression chamber, dramatically simplifying the mid-range assembly. Also, in three-way designs the mid-frequency horn and the high-frequency horn are physically pointing to different locations in front of the box. The SR1530 features an "Optimized Wavefront" horn design. Unlike typical mid/high horns, the high-frequency section is positioned to fire down into the six-inch midrange's dispersion pattern. This creates a focused, single wave front with excellent phase and power response characteristics. The mid-range transducer operates between 700 Hz and 3,000 Hz eliminating the placement of a crossover point in the middle of critical voice frequencies. Frequencies above 3,000 Hz are reproduced by a 1inch exit compression driver. There are two 100 watt amplifiers for the mid and high-frequency drivers.  The SR1530 deep bass is produced through a 15-inch high-output woofer. The transducer handles 250 watts rms long term. The low-frequency amplifier is an excellent example of the efficiency of active designs. The amplifier uses a high efficiency, high current Class G topology to produce 300 watts rms of power.  The SR1530 frequency response is linear between 45 Hz and 18 kHz. The system processor provides complete system management of all electronic and acoustic functions. These functions include electronic active crossover, electronic phase alignment, electronic time correction, electronic equalization, and complete amplifier and component protection. The system accepts a standard line level signal via an XLR input connector. There is also a loop out connector (continued on page 2) Features  Three-way tri-amplified, horn-loaded sound reinforcement speaker system  High definition, high output levels before feedback  500 watts of integrated power  Electronic equalization, time correction, and phase alignment  Complete electronic and component protection circuitry  Wide dispersion, extreme output high/mid horn design  High-output six-inch horn loaded mid-range transducer  High-precision one-inch exit, high- frequency compression driver  15-inch woofer with high-flux magnetic circuit  Professional trap designed enclosure  Correctly weight-balanced with two comfortable side handles for easy carrying and set up  One top and one bottom handle for easy repositioning of speaker Applications  Live applications  Playback applications  Small to medium sized portable PA systems  Corporate events  Night clubs  Houses of worship 1 OF 6 PAGES SR1530
