Mackie SRS-1500 Self Powered Subwoofer
The SRS1500 is a high output active subwoofer system. It features a high-precision 15 ̋ transducer combined with application specific amplifier technology. The system is composed of a single, compact subwoofer cabinet with built-in control and amplifier electronics.
Connecting and setting up the SRS1500 is a breeze. It accepts a stereo line-level signal via female XLR input jacks. Male XLR Thru jacks are provided for daisy- chaining the signal to additional SRS1500 cabinets. The built-in crossover separates the low frequencies from the high frequencies, and routes the high frequencies to the male XLR high-pass output jacks. Connect these to the inputs of full-range active speakers such as the Mackie Designs SRM450s, or to an amplifier powering a pair of passive speakers. A Phase switch gives you the option of reversing the polarity of the signal to the full-range speakers by 180º. A Subwoofer Level control allows you to adjust the balance between the subwoofer and the full-range speakers.
The built-in amplifier produces 600 watts of continuous power. The amplifier module sits on a mammoth heatsink that eliminates the need for fans, dramatically extending life expectancy, and eliminating maintenance cycles. A tremendous benefit of having the amplifier located within the subwoofer cabinet is that the SRS1500 functions as a system, optimizing acoustic, electronic, and mechanical designs to achieve the highest level of performance and value. The cabinet is constructed with 18mm thick multi-layered birch plywood. Carrying handles are integrated into each side for easy loading and transport.
