OVERVIEW
The SR1530 is a high output, horn loaded, 3-way, wide dispersion, active sound
reinforcement system. It features a one-piece 90º x 40º horn, which includes both the mid
and high frequency sections in a proprietary "Optimal Wavefront" design. Unlike typical
mid/high horn designs, the high frequency section is positioned to fire down into the six-
inch mid-range's dispersion pattern. This creates a focused, single wave front with
excellent phase and power response characteristics.
The mid-range transducer operates between 700Hz and 3000Hz, eliminating the
placement of a crossover point in the middle of critical voice frequencies. Frequencies
above 3000Hz are reproduced by a 1-inch exit compression driver. The low frequencies
are produced through a high output 15-inch woofer.
The SR1530 accepts a line-level signal via a female XLR input jack. A male XLR Thru jack is
provided for daisy-chaining the signal to additional SR1530 cabinets.
Two built-in power amplifiers provide 100 watts each for the mid-frequency and high-
frequency drivers. The low-frequency driver is powered by a high-efficiency, high-current
Class G topology amplifier providing 300 watts of power. The amplifier modules sit on a
large heatsink that eliminates the need for fans, dramatically extending life expectancy,
and eliminating maintenance cycles.
The cabinet is constructed using both 18mm multi-layered plywood and pressure injected
structural resin. Two carrying handles are integrated into each side for easy loading and
transport.
