The ENTASYS Pan-Tilt Bracket Kit, designated ENT-PT, is used to provide a down-tilt angle (rotation about a horizontal axis) and a panning action (rotation about a vertical axis) when an ENTASYS column or tall array is mounted to a wall. The Pan-Tilt Bracket Kit consists of two primary parts, a Top Assembly and a Bottom Piece, as shown in Figure 4. The Top Assembly consists of multiple parts that are configured and assembled to yield the desired down angle for an array of up to five columns. After the Pan Tilt Bracket Assembly is put together it is mounted to a wall and then the ENTASYS loudspeaker(s) are attached to it. The Pan-Tilt bracket can be used with a one, two, or three column array for a down-tilt angle of up to 10°. With a four or five column array the maximum down-tilt angle is 5°. All parts in the kit are engineered to provide a high margin of safety when used in accordance with these instructions. The brackets are manufactured of steel and are covered with a durable powder-coat finish. Kits are available in either black or white to match the color of the enclosures.
The ENTASYS high-performance column line array loudspeaker system is designed for permanent installation in applications such as auditoriums, airports, train stations, conference centers, lecture halls, houses of worship, stadium concourses and museums. ENTASYS features a unique three-way Full-Range Column and a Low Frequency Column in the same size enclosure, offering superior performance, high output and high power handling capability in an architecturally appealing design that is weather-resistant for outdoor installations.Unlike other column products on the market, the ENTASYS system provides consistent horizontal and vertical coverage from 800 Hz to 16 kHz from a single loudspeaker.
The ENTASYS line of loudspeakers features just two loudspeaker models but they are able to be configured and deployed to achieve very high SPL, exceptional sound quality and outstanding speech intelligibility. This is accomplished through the use of multiple drivers in each pass band of the loudspeaker system. Particular attention was paid to driver spacing, including the development of a patent-pending Compact Ribbon Emulator, a device that allows a line of 1-inch drivers to effectively produce a single ribbon of energy. The spacing of the drivers used in ENTASYS has been optimized for the frequency region that they reproduce to minimize the formation of grating lobes in the vertical plane.
ENTASYS systems are designed to be modular. Multiple enclosures may be stacked and joined together to form larger column line arrays. The Full-Range and Low Frequency enclosures can be arranged in any order to direct the sound only where it's needed, and to extend the length of the column to provide additional low frequency pattern control. This enables the sound system designer to specify the best performing configuration for a given application.
Each individual enclosure features a compact 5.5 inch wide by 7.375 inch deep "teardrop" shaped footprint and stands 44.5 inches tall. An extremely low-profile T-Bar mounting bracket is included with each ENTASYS column for straight "flush" mounting. Since the connector panels are situated on the top and bottom of the modules, the assemblies can be installed virtually flush with the wall, with invisible connections between modules. The result is an attractive, cost competitive system with excellent projection and pattern consistency in both horizontal and vertical coverage. ENTASYS systems provide excellent intelligibility, feedback rejection, and wide frequency response.
The only additional items required to make ENTASYS work are a high pass filter and a power amplifier. An equalizer may also be used, if desired, but is not required to deliver exceptional sound quality. Each
ENTASYS loudspeaker has its own internal passive crossover to provide the required filtering. An external high pass filter is recommended to allow ENTASYS to reach its maximum performance potential.
