One Systems’ Portable Outdoor Powered System (POPS) was designed to fulfill a unique need in the professional audio marketplace for a high-output powered speaker system that can be used outdoors in any weather condition.
POPS15a is a 15-inch two-way system that includes onboard digital power amplifiers and digital signal processing (DSP) with dynamics and protection. POPS15a was designed for direct-weather applications and its enclosure, electronics and transducers have been developed for use in rain, snow and other inclement weather applications. Its highly-portable design and flexible features makes it ideal for mobile applications indoors and outdoors.
POPS15a’s enclosure is injection-molded using a special resin designed for use in harsh weather conditions and high UV exposure. POPS15a’s gray-colored, near infra-red reflective resin is able to withstand high ultra-violet exposure and its reflective color minimizes solar-induced heat build-up to prevent the amplifiers from output limiting or shutdown when used in high ambient temperatures and/or direct sunlight. All system rigging and components are made of very high grade stainless steel. The enclosure has been designed to IEC 529 / IP 56 ingress protection standards and its transducers are designed to meet weather/water proof requirements. All its electronic switches and input/output connections meet IP 67 standards or better.
POPS15a’s digital power amplifier, built by Powersoft® in Florence, Italy, provides 2,000 peak watts of output power and is bi-amplified with the headroom necessary for modern presentation and music systems. The onboard digital processing provides high-order filtering and crossover functions, free-field optimized equalization and system dynamics and protection algorithms. The system’s dynamics processing has been designed to provide excellent system protection while maximizing its peak acoustic output capability.
POPS15a’s components include a 60º x 40º High-Q horn coupled to a medium-format compression driver that delivers impressive projection with superb pattern control. The low frequency transducer is a unique Narrow-Profile design that utilizes a 15-inch (381 mm) cone with a very large 4-inch (101 mm) diameter voice coil. This extremely large voice coil diameter provides superb reliability and high power handling while minimizing power compression effects. The driver’s neodymium-iron-boron magnets have been optimized using finite-element modeling techniques to insure maximized efficiency bandwidth The compression driver’s titanium diaphragm that features an exit geometry optimized for superior acoustic loading and extended bandwidth directivity control.
POPS15a features 7 x M10 stainless steel rigging points as well as an integrated loudspeaker stand adaptor. It may be suspended horizontally or vertically using the optional Eye Bolt Kit. POPS15a may also be mounted on a loudspeaker stand with a standard-sized 1-3/8″ (35 mm) diameter pole. Its specially-shaped enclosure also permits its use as a floor monitor.
POPS15a includes custom 30.5 m / 100 ft-long AC Mains cable and an IP 67-rated XLR signal cable with moisture-resistant connectors. Both cable assemblies are supplied on portable cable reels for fast system setup and easy transportation. The AC mains cable is equipped with an inline Ground Fault Circuit Interrupter (GFCI) for added safety.
Thanks to its premium components, rugged injection-molded enclosure, high-performance Powersoft® amplifiers and digital processing, POPS15ais a perfect solution for a variety of applications indoors or outside that require an integrated system that is quick to set up, easy to use and is capable of delivering excellent performance.
