3 Introduction
The Electro-Voice Expandable Vertical Array (EVA) line-array modules represent an important
step in line-array technology for small- and medium-scale fixed-installation sound
reinforcement.
The four base models are designed to simplify the physical assembly of a line array. Also,
arrays of EVA full-range modules are designed to be powered from one amplifier channel.
Sophisticated passive networks provide the necessary crossover and EQ functions.
The individual loudspeaker drivers, Hydra™ waveform converters, acoustic waveguides,
enclosures and rigging hardware were all designed specifically for the EVA product line. The
goal is to achieve the highest acoustic output with the highest fidelity and produce a precise
wavefront from each element to achieve state-of-the-art line-array performance.
The EVA subwoofer modules complement both the appearance and performance of the EVA
full-range modules in applications where additional low-frequency output is required from a
flown array.
EVA loudspeaker arrays present an affordable option for projects that require a line array
approach, but have limited budgets. At the same time, the performance of fully passive EVA
systems rivals that of more expensive and complex line arrays. EVA was designed for
outstanding sound quality with only minor equalization for room compensation, without any
speaker-specific settings.
But Electro-Voice also offers EVA loudspeaker settings that can be loaded into Dynacord
amplifiers and processors by using SONICUE System Software. The settings add protective
limiters to reduce the risk of loudspeaker failure, and allow higher drive levels.

3.2 Features
Although the EVA full-range modules are not the same, their acoustic polar responses are
substantially symmetrical. You can construct stereo-left and -right arrays or left-center-right
arrays with the modules in their normal right-side-up orientation. Alternatively, 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.
Each EVA full-range module contains two separate, vertically stacked line-array elements
splayed within the module at one-half the included vertical angle of the vertically trapezoidal
enclosure. The two elements of each module consist of two vertically stacked EVS2008 8-inch
(203mm) LF drivers (one per element) and two pairs of DH2005 1.25-inch-diaphragm
(32mm) HF drivers (one pair per element). Each HF driver pair is mounted on a Hydra™
waveform converter, the two of which are vertically stacked and splayed with their respective
elements. Each module functions as one self-contained zone within an array. The added
benefit of the internal shading network attenuates the upper or lower HF driver pair by 3dB to
help smooth transition between zones when needed.
EVA-2082S/906 full-range module
EVA-2082S/906 is a 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 vertical plane with a 6° total included angle. The two line-array
elements contained in the module are vertically splayed by 3°.

EVA-2082S/920 full-range module
EVA-2082S/920 is a two-way, LF/HF line-array module with a 90° horizontal x 20° vertical
coverage pattern (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 full-range module
EVA-2082S/126 is a 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 vertical plane with a 6° total included angle. The two line-array
elements contained in the module are vertically splayed by 3°.
EVA-2082S/1220 full-range module
EVA-2082S/1220 is a two-way, LF/HF line-array module with a 120° horizontal x 20° vertical
coverage pattern (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 attenuation module
The EVA-AM attenuation module mounts on the inside of an EVA-2082S input panel, and
attenuates the entire module by 3, 6 or 9dB. The nominal impedance of an EVA-2082S module
is 16ohms. Up to six paralleled EVA-2082S modules can be driven from a single amplifier
channel capable of driving a 2.7-ohm nominal impedance (16ohms ÷ 6 modules = 2.7ohms).
If at least two of the modules have the optional EVA-AM attenuation modules installed, a single
amplifier channel capable of driving a 2.3-ohm nominal impedance can drive up to eight
paralleled EVA-2082S modules.
EVA-1151D single subwoofer module (discontinued)
EVA-1151D is a compact single 15-inch subwoofer module capable of being flown either above
or behind an EVA full-range array. EVA-1151D is a rectangular unit with special tie plates that
allow for assembly with either 0° or 5° of splay between modules. It may also be used in a
stand-alone subwoofer array or ground-stacked.
EVA-2151D dual subwoofer module
EVA-2151D is a large rectangular dual 15-inch subwoofer module designed for use only at the
top of an EVA full-range array. It may also be used in a stand-alone subwoofer array or ground-
stacked.
Both subwoofers use the DVX3159A 15-inch (381mm) woofer designed specifically for
subwoofer duty, providing reliable low-frequency performance at high SPL levels with low
distortion and solid impact.
i
Notice!
Subwoofer modules do not have internal passive crossovers and require an active crossover
and dedicated amplifier channel(s) for proper operation.
The standard EVA indoor versions are finished in tough EVCoat™. All EVA modules (except
EVA-2151D ) are available in two levels of weather resistance:
– Fiberglass (FG) versions like EVA-2082S/906-FGB are designed for full weather exposure.
They feature a fiberglass-finished enclosure, stainless-steel three-layer hydrophobic grille
and the CDG dual-gland-nut input-panel cover.

2023-01 | 04 | F01U196199 Installation manual Electro-Voice
– Permanent Install (PI) versions like EVA-2082S/906-PIB are rated for indirect outdoor
exposure only in protected areas, such as under a roof overhang. They feature a stainless-
steel three-layer hydrophobic grille and the CDG dual-gland-nut input-panel cover on an
enclosure finished in standard EVCoat.
External fasteners on all EVA systems are stainless steel.
All EVA modules are available in black or white and are supplied with the hardware necessary
to fasten one module to another. Two cosmetic side cover panels give the finished array a
smooth and uncluttered appearance. The end caps on the fiberglass versions are also finished
in fiberglass. Black is indicated by BLK or B at the end of the complete model number and

EVA-2082S/906-BLK and EVA-2082S/906-PIB.
3.3 Accessories
EVA-SG2 standard grid
EVA-SG2 is a standard grid for typical down angles with small arrays, or top and bottom
suspension for extreme down angles in large arrays of EVA-1151D subwoofer (discontinued)
and/or EVA-2082S full-range modules.
Not for use with EVA-2151D subwoofer.
EVA-EG2 extended grid
EVA-EG2 is an extended grid for extreme down angles in small to medium arrays and typical
down angles in large arrays. EVA-EG2 is the only grid for flying EVA-2151D subwoofers.
EVA-CG coupler grid (discontinued)
EVA-CG is a coupler grid for flying EVA-1151D subwoofer modules (discontinued) behind an
EVA full-range array.
i
Notice!
The three different grid options (EVA-SG2, EVA-EG2 and EVA-CG) are sold separately. Consult
the PREVIEW Loudspeaker Software for proper grid selection.
!
Caution!
Series 2 grids (EVA-SG2, EVA-EG2) are required to fly EVA subwoofer modules. Older grids
(EVA-SG, EVA-EG) are used for flying EVA full-range modules only.
EVA-GXB extra spreader bar
EVA-GXB is an optional second spreader bar for EVA grids, to be used when two-point front-to-
back hangs are required.
i
Notice!
The need to maintain sufficient pressure on the forward rigging point limits the amount of
down angle available with the standard EVA grids (EVA-SG or EVA-SG2) in this configuration.
CDG cover plate
An optional dual-gland-nut input panel cover is used to protect the input connections from
water.

5 Designing an array
!
Warning!
When flown in the same column with full-range modules from an EVA-SG2 or EVA-EG2 grid,
subwoofers must always be at the top of the array.
5.1 Designing and optimizing arrays
The total included vertical angles of the EVA modules in side view (6° for long-throw and 20°
for short-throw) were determined after analyzing array simulations in a wide range of venues.
Optimal distance for uniform front-to-back coverage is 100ft ±25ft.
Use Electro-Voice PREVIEW Loudspeaker Software to design and optimize EVA arrays for a
specific situation. You can download the latest version of PREVIEW from the EV website.
A good rule of thumb for aiming a three- or four-box array in a venue with a flat floor is to have
a line running through the intersection of the top two modules intersect the head of the
person in the last row.
Figure5.1: Rule-of-thumb for aiming three- and four-module EVA arrays
The Array Optimizer function in PREVIEW Loudspeaker Software determines the best aiming
angle for any valid combination of EVA-2082 modules.
GLL files for EVA simulations in EASE or EASE Focus are posted for download from the
Electro-Voice website. You can predict the coverage of EVA arrays in these software
applications, but you cannot validate rigging configurations.
5.2 Typical number of arrays
Line-array systems usually consist of vertical columns of multiple independent line-array
elements. The most common implementation is a sound reinforcement system with two
columns (left and right). Additional columns cover different seating sections of a venue, such
as seating areas that wrap around the side or back of a stage. Left-center-right configurations
use the center channel for speech.
A single array can provide good coverage in some venues. A variation of such a monaural
system is the exploded array, where two or more widely spaced (approximately 10ft or more)
arrays provide the horizontal coverage required. Distributed systems, such as in an arena, use
a large number of arrays.

2023-01 | 04 | F01U196199 Installation manual Electro-Voice
6 Preparing modules for installation
6.1 Recommended preflight procedures
For any sound system, certain checks made at the installer’s place of business can prevent
expensive on-site delays. A short-list follows, and sets the stage for proper array performance:
1. Unpack all loudspeakers in the shop.
2. Check for proper model numbers.
3. Check the overall condition of the loudspeakers.
4. Check for continuity at the loudspeaker inputs.
It is a good idea, once on-site and the loudspeakers are connected, to check again for
continuity at the power-amplifier end.
6.2 Module configuration
While modeling an EVA system in the PREVIEW Loudspeaker Software, you can shade the
loudspeakers with the high-frequency attenuation card in the input cup, or with optional
attenuation modules. You need to perform this shading manually when the system is rigged
and suspended.
i
Notice!
It is possible to complete shading adjustments and installation of attenuation modules at the
installer’s shop. Make certain that EVA modules are properly identified to avoid misassembly
of the array in the field.
Use of high-frequency shading
An EVA HF shading switch card comes pre-inserted in the “Center = Both @ 0 dB” position,
indicating no shading of either HF element.
To attenuate the top HF element:
– Remove the switch card by drawing it toward you using the central finger hole.
It is possible to remove the switch with the end of a flat-blade screwdriver. Place the
blade end in the switch hole and use the adjacent edge of the input panel as a fulcrum. A
small recess in the edge of the input panel opposite to the hole in switch card facilitates
this operation.

To shade the upper HF element by 3dB:
4Reinsert the switch card one step higher.
Figure6.2: EVA input panel, with the switch card inserted to shade the upper HF element by 3 dB
To shade the lower HF element:
4Reinsert the switch card one step lower.
Figure6.3: EVA input panel, with the switch card inserted to shade the lower HF element by 3 dB
Use of optional attenuation modules
Some array designs also use one or more of the optional EVA-AM attenuation modules.
i
Notice!
The EVA-AM is for use only with EVA-2082S full-range modules.
To attach the EVA-AM attenuation modules to the inside of the input-panel assembly:
1. Using a Phillips #2 screwdriver, remove the eight screws holding the input panel in place.
The cable assembly that connects the green PC board of the input panel to the crossover/
equalizer network inside the EVA module is long enough to allow the input-panel
assembly to rest on a flat surface close to the EVA module. If necessary, disconnect the
crossover/equalizer cable temporarily.
