115UM™

The 115UM is a 15″ two-way high output sound reinforcement system. The enclosure geometry allows the 115UM to be used as either a utility enclosure or a high output floor monitor. The 115UM may be used in outdoor installations as well as indoor applications where high intelligibility and accuracy are required. Like all One Systems products, the 115UM was designed not only offer excellent full range fidelity but superior vocal reproduction and intelligibility as well. The system consists of a single 15 inch 15I/O woofer and an ETS driver on a fully rotatable high-frequency horn.

The ONE SYSTEMS 115UM features an 18mm birch plywood enclosure that utilizes stainless steel internal structural supports to enable a variety of suspension points when it is used in a “utility” mode. The 45 degree angle also makes the 115UM an ideal floor monitor for professional applications. Because of its small size, the 115UM also features an integral stand/pole mount adaptor.

The grill is a 3 layer “rain shield” design that will minimize direct rain contact with the systems transducers. All internal and external metal hardware, as well as the grill, are stainless steel. The enclosure and grill design are rated to IEC 529 IP45 (solid object penetration to 1 mm (0.04 inches) and water jets from any direction). The enclosures and components are also rated to Mil Spec 810.

The input section consists of both 4 pin Neutrik Speakons as well as a stainless steel hardware barrier strip.

A weather cover is provided with an integral gland nut connector for outdoor applications. In the outdoor configuration connections are made thru the 4 position barrier strip. The input is user switchable for wither full range or bi amp operation. The switch is located on the inpt plate and is isolated from direct weather by the weather cover. accommodate most 2 conductor AWG 12 cable assemblies.

The Gland nut is weather proof and is rated NEMA 60 (IP68). The connector will accomodate cable outside diameters from 7mm to 12mm (0.236″ to 0.472″). The maximum diameter will accommodate most 2 conductor AWG 12 cable assemblies.

The basic design utilizes a patent pending high-frequency driver and horn combination. The fully rotatable high-frequency horn has a pattern of 105 degrees by 60 degrees.The ETS design offers extended bandwidth polar control and very low distortion. The ETS-105/60 is a 105 degree horizontal by 60 degree vertical pattern and may be rotated to also provide a 60 degree horizontal by 105 degree vertical for short throw and downfill applications.

The patent pending ET-2 large format driver is a unique “equivalent throat” design that allows the radiation pattern to be controlled by the phase plug summation plane rather then the conventional “exit diameter” at the end of the driver structure. This feature provides extended high-frequency dispersion. The ET-2 large format driver has a titanium diaphragm and a close spaced circumferential ring phase plug to ensure extended high-frequency bandwidth.

The low-frequency design is also patent pending. The 15 inch I/O woofer (Inside Only) utilizes a unique voice coil wind on the inside of the voice coil support structure. This design allows for both high magnetic system displacement as well as increased thermal transfer. This results in reduced power compression and higher reliability.Because the ONE SYSTEMS 115UM is designed for both floor monitor and permanent installation applications a variety of rigging and suspension options are available. The 115UM has 12 M10 mounting points. An M10 forged shoulder eye bolt kit is available for all M10 suspension points.
