SPEAKER
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 feature 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 1- inch 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

for additional signal routing. To ensure long term reliability and performance, the amplifiers are mounted on a massive heat sink, which is convection cooled and dramatically extends the life expectancy of the heatproducing components.
The SR1530 cabinet is constructed using both multilayered plywood and pressure injected structural resin. The combination provides a robust enclosure system with useful ergonomic features. There are three-part cast aluminum handles on each side of the enclosure for easy carrying and setup. Handles are located on the top and bottom of the cabinet for easy movement and relocation. A full size, oval punched, weather resistant steel grille protects the front of the cabinet.
