1.0 Introduction

The Electro-Voice® EVA (Expandable Vertical Array) loudspeaker systems or line-array modules represent an important step in line-array technology for small- and medium-scale fixed-installation sound reinforce- ment. The four models are designed to significantly simplify the physical assembly of a line array. Also, arrays of EVA modules are designed to be powered from one amplifier channel, the necessary crossover and EQ functions accomplished with sophisticated passive networks. The individual loudspeaker drivers, Hydra™ plane-wave generators, acoustic waveguides, enclosures and rigging hardware were all designed specifically for the EVA product line to not only achieve the highest acoustic output with the highest fidel- ity but also produce a precise wavefront from each element to achieve state-of-the-art line-array perfor- mance. A brief description of the product line is included below. The EVA modules are shown in Figure 1 with key dimensions and features.

Although the EVA modules shown in Figure 1 are not physically symmetrical, their acoustic polar respons- es are substantially symmetrical. Thus, stereo left and right arrays or left-center-right arrays may be con- structed with the modules in their normal right-side-up orientation as shown in Figure 1. However, should the user desire, the module attachment points are such that mirror-image left-right arrays can be made by constructing one array with its modules turned upside down with respect to the views of Figure 1.

Each EVA module contains two separate, vertically stacked line-array elements.

EVA-2082S/906:two-way, LF/HF line-array module with a 90° horizontal x 6° vertical coverage pattern (for long throws) and passive crossover/HF-shading/EQ network. The enclosure is trapezoidal in the verti- cal plane with a 6° total included angle. The two line-array elements contained in the module are vertically splayed by 3°.

EVA-2082S/920:two-way, LF/HF line-array module with a 90° horizontal x 20° vertical coverage pat- tern (for short throws) and passive crossover/HF-shading/EQ network. The enclosure is trapezoidal in the vertical plane with a 20° total included angle. The two line-array elements contained in the module are vertically splayed by 10°.

EVA-2082S/126:two-way, LF/HF line-array module with a 120° horizontal x 6° vertical coverage pattern (for long throws) and passive crossover/HF-shading/EQ network. The enclosure is trapezoidal in the verti- cal plane with a 6° total included angle. The two line-array elements contained in the module are vertically splayed by 3°.

EVA-2082S/1220:two-way, LF/HF line-array module with a 120° horizontal x 20° vertical coverage pat- tern (for short throws) and passive crossover/HF-shading/EQ network. The enclosure is trapezoidal in the vertical plane with a 20° total included angle. The two line-array elements contained in the module are vertically splayed by 10°.

EVA-AM:this optional attenuation module mounts on the inside of an EVA input panel, and attenuates the entire module by 3, 6 or 9 dB. The nominal impedance of an EVA module is 16 ohms. Up to six paralleled EVA modules can be driven from a single amplifier channel capable of driving a 2.7-ohm nominal imped- ance (16 ohms ÷ 6 modules = 2.7 ohms).
