Description

In the TS940D, Electro-Voice has combined its expertise in constant-directivity horns, high-frequency compression drivers and low- frequency speakers and enclosures to produce a compact, easily installed theatre stage sys- tem with superior performance in all areas: uniform dispersion to the higheest frequen- cies, high efficiency, high power capacity and wide, smooth frequency response.

The TS940D matches the only second-gen- eration constant-directivity high-frequency horn to a world-class high-frequency driver, providing accurate reproduction and cover- age of frequencies from500 Hz to 20,000 Hz. Electro-Voice invented constant-direectivity technology, first introduced in our HR series horns in 1974. The HP horn is the TS940D is

asignificant refinement. Constant directiv- ity means that all frequencies are enenly spread over the horn's rated coverage angle, so that every seat in the house can receive booth clear dialogue and subtle high-fre- quency effects. For low frequencies, two 15- inch woofers are vertically stacked in a di- rect-radiating configuration, providing a cov- erage pattern thatlosely matches that of the

high-frequency horn in the crossover region. Such a match is not possible with more tradi- tional horn-loaded bass enclosure. The high excursion woofers, mounted in an optimally vented, Thiele-Small enclosure, provide high- impact bass from 40-500 Hz, at average pow- ers up to 800 watts, when required. In the field, the TS940D's combination of high- and low-frequency reproduction has proven to be an excellent choice for small to medium sized houses.

The TS940D incorporates a number of in- staller-recommended features, for quick, trouble-free and low-cost installation. Among these features is a dedicated crossover/ equilizer that is easily flush mounted in the pre-sized, pre-drilled hole located in the side of the low-frequency enclosure. Side mount- ing provides easy wiring access when the system is installed against a wall. Through the use of the horn mounting kit and pre- drilled holes in the low-frequency system, the high-frequency section is easily mounted in the proper position on top of the low-fre- quency section. All pre-drilled holes are T- nut loaded, including bass driver mounting holes. This means quick and easy driver re- placement. All components of the TS940D

are finished in matte black, to eliminate any reflections back through the screen.

Frequency Response

Figure 2 shows TS992-LX frequency re- sponse with presets of the Electro-Voice Dx34A digital speaker system processor (see Crossover and Basic Equalization section). The measurement was made with a swept sine-wave signal, 4 volts at 500 Hz, in an anechoic (echoless) environment. The micro- phone was at a distance of 3.0 m (10 ft), on an axis at the lower edge of the high-fre- quency horn. Figure 3 shows the frequency response of the individual sections of the TS992-LX, measured under the same condi- tions but with a 4-volt input constant with frequency, the results of which were then nor- malized to 1 watt/1 meter.

Frequeny Response

The data was measured in an anechoic (echoless) environement at 20 feet on axis with 4 volts of swept 1/3-octave random noise. The frequency response curve for the TS940D is shown in Figure2.

TS940D specifications

The Electro-Voice TS940D is a professional-grade loudspeaker system designed for demanding performance environments. Renowned for its impressive sound quality and durability, the TS940D is an ideal choice for concert venues, auditoriums, and large events, offering a versatile solution for a wide range of sound reinforcement applications.

One of the standout features of the TS940D is its advanced transducer technology. The system is equipped with high-performance woofers that deliver deep, impactful bass and a frequency response that extends low enough to fill large spaces with rich audio. The 18-inch woofers provide a powerful low-end punch, making them suitable for genres that rely heavily on bass-driven sounds.

In terms of high-frequency performance, the TS940D utilizes custom-designed compression drivers coupled with a meticulously engineered waveguide. This configuration ensures exceptional clarity and dispersion, allowing the speaker to cover large areas evenly without significant drop-offs in sound quality. The system is capable of reproducing detailed vocals and crisp instrumentals, making it a top choice for live performances.

The build quality of the TS940D is another key characteristic that sets it apart from its competitors. Constructed with durable materials, the cabinet is designed to withstand the rigors of touring and extended use. Its rugged design is complemented by an aesthetically pleasing black finish, allowing it to blend seamlessly into any professional setting.

The TS940D is also equipped with advanced connectivity options, including both speakON and binding post inputs, simplifying integration with various sound systems and amplifiers. The loudspeaker features user-friendly controls that allow for easy adjustments to meet specific performance requirements.

Additionally, the TS940D is designed with enhanced thermal management technology, which helps prevent overheating during extended use. This feature ensures reliability and longevity, even in high-usage scenarios.

With its combination of powerful performance, durability, and advanced technology, the Electro-Voice TS940D is a top-tier loudspeaker that meets the demands of professional audio engineers and sound technicians. Whether for concerts, events, or installations, the TS940D provides an exceptional audio experience that truly elevates the standard for live sound reinforcement.
