INTRODUCTION
Thank you for choosing Mackie Designs’ active sound reinforcement speaker systems.
The FUSSION 1800SA and 1800S is an extreme output active subwoofer system. Designed to live on the road, this subwoofer system is a double 18˝ design broken down into two individual enclosures that make load-in and load-out quick and easy. It incorporates a 2500 watt high-efficiency amplifier system and two front-loaded, high-precision 18˝ woofers mounted within each cabinet. Connection and setup is a breeze. Just connect the SUB OUT line- level signal from a Fussion Series full-range active speaker, plug in the power cord, and you’re ready to go.
The FUSSION 1800SA accepts a line- level signal via a female XLR input jack. All Fussion Series full-range active speaker systems include a SUB OUT signal via a male XLR that connects to the subwoofer system quickly and easily. The FUSSION 1800SA is specifically designed to work with the FUSSION 1800S. Power for the passive 1800S is provided by the 1800SA via a Neutrik™ female Speakon connector located on the rear panel.
Because the amplifier is located just inches away from the driver within its own protected enclosure, the amplifier enjoys several benefits. It sees a non-reactive load with a constant impedance, which substantially improves performance. It also 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 FUSSION 1800SA functions as a system, optimizing acoustic, electronic, and mechanical designs to achieve the highest level of performance and value.
Size was a paramount design objective during the development of the FUSSION 1800SA and 1800S. Double 18˝ subwoofer bins are typically very heavy, bulky, and difficult to handle. We spent over a year speaking with regional touring companies and gaining valuable insight from their experiences and suggestions. The result is an extremely compact system that is easy to transport and set up.
High-Efficiency, High-Current Design
The FUSSION 1800SA is the first subwoofer system to incorporate a passively cooled, high-efficiency, high-current design into an enclosure. The physical design is based on an amp-module philosophy that facilitates easy field service and repair. Reproduction of transients was the key goal when designing the amplifier, and to accomplish this we used an exorbitant quantity of high-voltage capacitors in the power supply to store the necessary energy. The result is a compact system that delivers concert-level, high-quality performance without the need of external amplification and processing.
The FUSSION 3000 can run on 115VAC or 230VAC and features soft-start circuitry that eliminates “pops” and precisely controls in-rush surges. The cabinet is constructed of 13-ply, 18mm thick baltic birch wood and is coated with high impact, black textured paint.
