About Otto
Otto is a driver compliment for the Adaptive PerformanceTM
system. It is specifically designed to be utilized as an ideal
match for Anya and Anna. Otto extends the Adaptive PerformanceTM
into the sub-bass range, providing optimal low-frequency coverage
for the venue.
Array and Overall System Design
The system design practices for the Adaptive PerformanceTM
include considerations for array coherency and the use of
subwoofers. While the use of subwoofers is optional, certain music
types and environmental conditions may require additional subwoofer
support. If additional subwoofer support is desired, EAW Otto
should be utilized as the ideal match for Anya and Anna.
Array Coherency
Array coherency refers to the alignment and synchronization of
multiple modules within an array. It ensures that the sound
produced by each module combines effectively to create a coherent
and uniform coverage pattern.
Subwoofers
EAW Otto subwoofer extends the Adaptive PerformanceTM into the
sub-bass range, providing the optimal low-frequency coverage
pattern for the venue. It is recommended to use Otto as additional
subwoofer support when needed.
Product Usage Instructions
System Design Practices
When designing the system, it is important to consider the array
size, low-frequency pattern control, and effective throw distance.
The number of Anya enclosures in the array will affect the
directivity and coverage pattern.
Array Size and Low-Frequency Pattern Control
The number of Anya enclosures in the array affects the vertical
directivity. Adding more modules to the array will result in a more
pronounced and directive vertical pattern. The maximum number of
Anya enclosures suspended with a 10:1 design factor will produce an
extremely tight vertical pattern at 125Hz across the listening
area.
Effective Throw Distance
The effective throw distance is influenced by the array size and
low-frequency pattern control. A table is provided as a
rule-of-thumb guide to relate array size, low-frequency pattern
control, and effective throw distance. It assumes a flat audience
surface and an array suspended at a typical trim height of
approximately 10m/32 feet. For more complex audience geometries,
further study in Resolution is recommended.

About Adaptive PerformanceTM
Adaptive PerformanceTM is an EAW technology that allows FOH engineers and
system technicians to easily provide ideal coverage in any environment or
audience geometry. Utilizing proprietary software and hardware, Adaptive
Systems such as Anya, Anna, and Otto provide users with the remarkable ability
to define (and redefine) their coverage in situ, after the system has been
deployed or even midshow. Should the audience size increase or decrease, the
systems engineer can affect changes in seconds simply by entering the
desired coverage and uploading these parameters to the arrays. Adaptive
Systems accomplish this while also providing extraordinary output, consistency
and fidelity at all volume levels and coverage patterns.
This Application Guide will provide users with information on Adaptive System
application and design concepts, system integration, and examples using
typical venues.

Overview
About Adaptive Arrays
Adaptive arrays are designed using only three module types: Anya, Anna, and
Otto. Each column in an array can only consist of one module type, and columns
of Anya and Anna can be combined to create mixed, multi-column arrays. Since
the vertical coverage of the system is adaptable from 90° down to 90° up,
supplemental “downfill” or “upfill” enclosures are unnecessary. Attention
should be paid to the horizontal coverage requirements as Anya/Anna does not
increase or decrease coverage in the horizontal plane via DSP. This is
achieved by attaching additional columns to the array. Anya Driver Compliment
LF Dual 15″ direct radiating with Offset ApertureTM loading MF Six 5″
horn-loaded with CSATM apertures and Radial Phase PlugsTM HF Fourteen 1″
horn-loaded on proprietary waveguide Each component within an Anya module is
independently powered and processed using state-of-theart electronics. These
electronics are contained in each module’s Power Plant, providing 22 channels
of amplification, 22 channels of DSP, and all necessary networking components
in a field-replaceable highly weather-resistant package.
Anya Nominal Coverage Horizontal 70° when used as a single column. Columns
array on 60° centers (10° overlap total, 5° overlap from each column) to
minimize the transition from one column to another.
4
Vertical Completely Variable It should be noted that the vertical coverage
of Anya, as calculated by Resolution software, will almost always be
asymmetrical. Vertical coverage is never derived from fixed Q (i.e. 45°, 60°,
90°, aimed at 10° down) but will be contoured to provide the most consistent
coverage possible. This means that the pattern will be complex.
Anna Driver Compliment LF Dual 10″ direct radiating with Offset ApertureTM
loading MF Four 5″ horn-loaded with CSATM apertures and Radial Phase PlugsTM

Anna module is independently powered and processed using state-of-theart
electronics. These electronics are contained in each module’s Power Plant,
providing 14 channels of amplification, 14 channels of DSP and all necessary
networking components in a field-replaceable highly weather-resistant package.

the transition from one column to another.

About Otto
Otto arrays are designed with a single module type. Each Otto module includes
Offset Apertures in all four corners and two independently-processed 18″
woofers to generate a variety of coverage patterns, even from only a single
module. Otto modules are designed to be tight-packed, with interlocking
flybars and IR transceivers on all faces. “Shotgun” or end-fire arrays,
“delay-arc” or broadside arrays, and simple single-column stacks are all
readily achievable depending on the performance and logistical requirements of
a given event or venue. Otto is designed to both extend and augment the low-
frequency response of any Adaptive product. Depending on the system
configuration and performance needs, engineers may choose to low-pass Otto
simply to provide additional extension, or may overlap Otto and other Adaptive
products to supplement both extension and output. Otto Driver Compliment VLF
Dual 18″ woofers with Offset ApertureTM loading. As with all Adaptive
products, each driver is independently powered and processed. All
amplification and processing electronics are housed in the unit’s Power Plant.

Array and Overall System Design
Adaptive arrays are constructed in two different ways. The vertical coverage
is completely variable regardless of the number of modules in the column,
meaning that the number of modules deployed is determined by the SPL and
directivity requirements only. The horizontal coverage is increased by
physically adding columns to the array. Resolution software’s “Array
Assistant” is designed to assist in creating a 3-dimensional coverage
prediction based on the number of modules physically available. Simply define
the venue as a model in Resolution, launch the Array Assistant, and it will
guide you to the final result. Modifications to the result are certainly
possible, and both coverage requirements and the number of modules used can be
redefined or adjusted at any time. Each time a change is made in Resolution
the parameters are automatically recalculated and the results displayed for
review. Once it is confirmed that the model represents your intentions, simply
upload the new settings to the Adaptive arrays and the system will be ready.
Array Coherency Producing a coherent wavefront from multiple enclosures
containing multiple transducers represents the primary challenge in system
design, especially when these enclosures are arrayed in both the vertical and
horizontal planes. Fortunately, Anya and Anna were designed from the beginning
to maximize coherency by allowing each column in an array to be physically
configured in only one way. Modules hang straight without any “J” curvature
and combine horizontally with their cabinet faces completely closed. This
removes any opportunity for physically mismanaged arrays and provides a highly
predictable physical design from which to model.
Subwoofers Although the use of subwoofers is optional, certain music types and
environmental conditions may require additional subwoofer support. If
additional subwoofer support is desired, EAW Otto should be utilized as the
ideal match for Anya and Anna. This subwoofer extends Adaptive Performance
into the sub-bass range, providing the optimal low-frequency coverage pattern
for the venue.
System Design Practices
Designing with Anya and Anna The number of modules used in any Adaptive array
is predicated on a number of factors. Since the vertical dispersion of the
array is determined by EAW Resolution software and any sized column can be
adjusted anywhere within a 180° vertical beamwidth, the factors to be
considered in defining an Adaptive array design are simplified to the
following:
- Horizontal coverage The horizontal coverage for Anya is defined by how many columns are assembled in each array. Columns are arrayed in 60° arc segments (60°, 120°, 180°, 240°, 300°, 360°). Horizontal coverage for Anna is also defined by the number of columns in the array. Columns are arrayed in 90° arc segments (90°, 180°, 270°, 360°). Additionally, EAW Resolution applies processing to align multiple columns for the smallest column-to-column seam possible.
- Overall SPL requirement As one would expect, the overall available SPL
for an Adaptive array is determined by the number of enclosures in the array.
Often, systems are designed around
8
the demands for SPL at the mix position. Most professional Front-Of-House
(FOH) engineers have a sense of what sound levels they will need for their
particular artist. Adaptive modules are easily added or removed from arrays,
and a wide variety of SPL calculations performed to assist in accurately
determining the right number of modules needed for a given SPL requirement.
Additionally, Resolution’s Array Assistant is designed to assist the designer
in balancing coverage, output and consistency given a certain number of
available modules and any physical restrictions (maximum height and minimum
trim). 3) Directivity Anya, Anna, and Otto adhere to classic line source
theory when discussing directivity. Like any true line source, the frequency
at which directivity begins is determined by the overall physical length of
the line. More simply: the longer the array, the lower in frequency the array
can control the directivity. Directivity can have significant benefits in
controlling spill onto the stage, noise control in outdoor venues, minimizing
reflections indoors, and “throw” distance.
Using EAW ResolutionTM EAW Resolution is the key to determining the optimal
array configuration for any application. Rooted in EAW’s proprietary FChart
modeling and calculation engine, Resolution allows users to easily model any
venue and visualize a wide variety of array designs to determine what
particular array configuration is best suited to the venue. Users simply need
to define the array position, allowable trim, minimum clearance, and quantity
of modules available and use the Array Assistant to determine the optimal
array configuration for a given venue. In many situations no further
prediction work will be necessary for optimal results. Users can also adjust
the results after running the Array Assistant by manually adding/removing
modules or adjusting coverage and observing changes in predicted results. In
this way Adaptive arrays can be optimized for any application. Additionally,
Resolution interfaces directly with Adaptive Systems via the Dante protocol,
allowing users to easily upload the processing parameters for their system
directly from their model to the physical array, adjust equalization and
coverage, and monitor all Adaptive components in real time. No additional
software is necessary to use Adaptive systems. Please visit www.eaw.com to
download the latest version of Resolution.

How Array Length Affects Directivity It would be beyond the scope of this
guide to go into the physics of how line arrays behave. Regarding vertical
directivity, Anya and Anna behave similarly to any true line source. The
difference with Adaptive products is their ability to define that directivity
dynamically and across the entire audible spectrum. The key to directivity is
array length. This should not be confused with the number of drivers. A
properly designed line array system will exhibit the same directivity from the
same physical length regardless of whether this length is made up of 8″, 10″,
12″ or 15″ components. The determining factor is the length of the array
itself and how that length affects the wavelength being produced. The samples
below show three array types in the same venue. The first array is very short
with only 4 x Anya modules being deployed. The contour line feature in
Resolution has been used to clearly show the definition of the vertical
contour at 125Hz. It is clear that with this array length, the 125Hz frequency
is seeing only slight directivity control.
The second image demonstrates what would happen with the same frequency in the
same venue but with an Anya array of 12 modules instead of 4. It is quite
clear how much more directive the vertical has become in this image and if we
continue to add modules to the array, the effect will become more pronounced.
10
Finally, we see the result when the maximum number of Anya enclosures is
suspended (maintaining a 10:1 design factor). This 18-module column of Anya
produces an extremely tight vertical pattern at 125Hz across this listening
area. If directivity at lower frequencies is required for the application,
array length must be considered.
11
Below, a table relating array size, low-frequency pattern control and effective “throw” distance is provided as a rule-of-thumb guide. This assumes a flat audience surface and an array suspended at a typical trim height (i.e. approximately 10m/32 feet). More complex audience geometries will produce different results and should be studied in Resolution.

How Adaptive Systems Handle Horizontal Coverage with Multiple Columns One of
the major advantages of Adaptive Systems is the integration of multiple
columns for smooth, consistent, precise horizontal coverage at all
frequencies. With traditional line array systems, multiple horizontal arrays
(i.e. mains and out-fills) are physically separated and independent. During
setup, engineers choose a location to align them, accepting the consequences
of misalignment at other locations. With Adaptive Systems, tight-packed multi-
column arrays are fully integrated, working together as a singular entity to
achieve a coverage solution throughout the entire horizontal and vertical
coverage range of the entire array, not just each individual column. Great
benefit of this can be seen at lower frequencies, where the horizontal energy
of an array is adjusted to benefit the greatest number of seats possible. In
the below example, an array of three columns of 4 Anya modules each clearly
can be seen to manipulate the low-frequency pattern to provide optimal
coverage of the venue, allocating the available low-frequency energy from all
three columns down the long-throw side of the coverage area. No physical
changes are made between the two examples it is only the enabling and
disabling of the LF correction algorithm.
Above, an array without LF correction Low-frequency energy is directed
through centerline of array, diagonally. This is the `natural’ response of
this array geometry.
Above, an array with LF correction to shift the low-frequency energy towards
the majority of the audience (on the right side of the venue), reducing excess
bass energy behind the array and in the side audience areas. No physical
changes have been made to produce this benefit it is an inherent component
of how Adaptive Systems work.
13
Split Coverage to Avoid Balcony Faces and Other Obstacles Adaptive arrays
automatically “split” coverage to avoid balcony faces and other obstacles to
reduce slap-back. No additional steps are required of the user. Inherently,
Adaptive Systems minimize energy directed where there is no audience surface;
anywhere not explicitly covered has minimal energy to due to the excellent
off-axis performance of these systems. The precise amount of attenuation
possible will depend on the model geometry, array length, frequency and
coverage start and stop. In the extreme example below, it is clear that even
with no additional effort from the user other than to enter the audience
areas, coverage is tailored very precisely to provide energy only where
surfaces are present, with deep attenuation everywhere else:
Even with a less complicated venue, such as a single-balcony theater or
contemporary house of worship, energy is minimized on balcony faces and under-
balcony rear walls:

Truck Pack Examples Several example truck pack configurations are displayed
below, and show recommended packing configurations for various Adaptive
systems. These configurations are based on product pallet dimensions, and
typical truck interior dimensions.
15
Integrating Otto with Anya and Anna Adaptive systems were designed for
seamless integration of Otto subwoofers with Anya and Anna. Leveraging the
same core Adaptive PerformanceTM technology, Anya, Anna, and Otto systems are
designed to be used together to provide ideal broadband coverage of any venue.
The recommended ratio of Otto modules to complement an Anya or Anna system
vary by musical genre, desired LF “bump” relative to mid- and high-frequency
output, and overall output level relative to available headroom . The
following ratios should serve as a general rule in sizing Adaptive systems,
representing the relative subwoofer/full-range balance at full output of both
systems. Note that in some cases Anya/Anna arrays may have sufficient low-
frequency headroom such that no Otto subwoofers are necessary.

This example represents a fan-shaped venue with a balcony, and sloped seating areas leading from the floor to the balcony on either side of the space. Utilizing three arrays of 4x modules each, Anna is able to provide an average 104 dB to every seat in the house, without supplemental fills. Anna also minimizes reflected energy from the balcony face much more effectively than traditional line arrays or point source clusters. A pair of Otto subwoofers flown immediately behind each array provides low frequency extension, and utilizes Adaptive processing to provide low frequency rejection behind the arrays.

This example represents an outdoor “shed”-style venue, including a heavily-

Often situated in suburban areas, shed venues can be the source of community-
sensitive noise issues. Compared to traditional line array products, Anna and
Otto provide a tremendous advantage in controlling noise spill to adjacent
neighborhoods with their ability to adjust coverage through a few clicks in
software. The engineer can direct the system to reduce coverage as needed
throughout an event, even mid-show, without any physical changes to the
arrays.

Venue: Outdoor Festival
Perspective Venue View
Outdoor festivals include a number of inherent challenges. First and foremost,
the typical audience areas and throw distances are very large. The following
example shows a large concert area (550′ deep x 650′ wide) for a well-known
festival in the UK. The design uses two arrays, each with one main column of
16x Anya modules and one outfill column of 12x modules. The system is clearly
capable of addressing the 500+ foot throw without any need for delay towers,
delivering consistent coverage to the most distant listeners. As mentioned
before, a major advantage with Anya over any other pro-touring system on the
market is its ability to tailor coverage in-situ. It is no secret that major
outdoor festivals endure the wrath of surrounding neighborhoods on a regular
basis and noise control is of paramount importance to festival promoters and
city government. Most festivals begin early in the day and run late into the
evening. The first half of the day is usually light on festival attendees
relative to the number that can be expected for the headliners later in the
evening. Still, with conventional systems, there is no way to tailor the
coverage. The mains will run all day long in full coverage regardless of how
many attendees are present. While delay rings may be turned off until they are
required later in the evening the mains cannot be altered Anya has the ability
to alter the coverage to whatever the needs are at any time. Coverage could be
0 to 50 feet at the beginning and 20 to 300 in the evening or anywhere in
between. The ability to tailor the coverage in such a way minimizes
unnecessary spill to the surrounding areas. The key is that even reducing the
coverage of the system does not disrupt the directivity control. With a
traditional system to attempt this would mean turning off sections of the
arrays which would reduce its ability to control
29
low frequencies. With Adaptive systems, the array’s total output is available
wherever coverage is defined. In the examples below, both full-coverage’ and reduced-coverage’ options are presented. In the `reduced-coverage’ scenario,
SPL in the coverage zone is increased because the entire array is now
being applied to a smaller area.
