An introduction to

Introduction to EAW Resolution™

Resolution is proprietary EAW software created to aid end users in the proper prediction and

application of EAW loudspeaker products.

Its intuitive work surface and exceptional modeling accuracy is based largely on the fact that the

engine driving it is derived directly from EAW’s internal usage only software F-Chart.

F-Chart is the software responsible for not only modeling EAW loudspeaker designs but also to dene

the algorithms used in the proprietary acoustic correction signal processing known as “Focusing”. For

this reason, the accuracy of the Resolution software is unrivaled as the end user is using the same

calculations used to develop the loudspeakers in the rst place.

Resolution is not limited to just line array systems. The software has the capacity to also implement

subwoofers and standard trapezoidal enclosures from EAW. The long-term goal of the software

designers is to have a program that can calculate as many EAW products as is necessary to aid the end

user in creating the best sounding systems possible.

The Work Surface: Venue Tab, Array Tab and Mapping Area

The Venue tab is where the work begins.

It is the area in which you will build the room that will house your loudspeaker array design.

The default view for Resolution is a section but a plan view can also be selected to see horizontal

coverage and interaction between adjacent loudspeakers or arrays.

Once the venue has been designed the user can now click over to the Array Tab work area.

This is where you will select and place the desired loudspeakers within your room model.

You have the option of manually entering all of the necessary data, using the software’s very powerful

“Array Assistant” or use a combination of both to achieve the perfect balance of what the computer

calculates and what you see as the perfect design.

The “Array Pane” is where the virtual arrays will be presented.

This is your opportunity to visualize the arrays shape and to also review the mechanical data required

to install a system that is both accurate in its deployment and also safe in its capacity.

The power of Resolution is realized in the SPL“mapping area”.

This is where hundreds of calculations are performed by the software and the results of all your hard

work are displayed.

Not only can you view the arrays individually or combined in the mapping area, you can also see these

arrays displayed in both section and plan views for nite array adjustment.

Windows Toolbar Menus

The toolbar across the top of the work area holds many valuable options that will aid you in setup and

execution of the software. While many of the menus are common in software programs, some include

Resolution-specic options.

File Menu

New – Creates a new Resolution design le

Open – Allows you to open a previously stored design le

Save – Allows the user to quickly save a design le (best when you already have the design stored

under a unique name)

Save As – Opens the option to save the design le with a unique name and in a unique location on

your PC

Import – This is where the user may import an EASE le into the software.

Export EASE File – This feature will create a“single-balloon” le that can be imported into the

EASE software which is excellent for speeding up the modeling process. Instead of calculating each

individual loudspeaker in the design, EASE receives a le that is already pre-calculated by Resolution

and hence only needs to process a single entity!

Create PDF – This will create a PDF of all pertinent data in the current design. This is handy for riggers

and stagehands in system assembly

Create CSV – Creates an “Excel” spreadsheet with all pertinent data of the design.

Recent Files – Remembers the last design les you were working on for quick reload.

Exit – Exits the Resolution program

Edit Menu

The “Edit” menu is very small.

This is where you can Undo or Redo previous keystrokes.

Undo - If you dislike what you just did to the perfect design you can “Undo” the move.

Redo - If you decide that you liked it after-all you can redo the move again with “Redo”

View Menu

The “View” menu has many options that are extremely helpful to the operator of the software.

Aiming Lines – This will toggle on or o green lines that extend from each individual loudspeaker in

the array to the point where it impacts a surface. The aiming lines extend perpendicular to the face of

each enclosure but do not dene the absolute coverage. They are a visual reference for the user to see

where each enclosure is projecting.

Aiming Coverage Lines – This will toggle on or o two red lines that dene the usable upper and

lower extremities of the arrays coverage. The aiming coverage lines can be used as the upper limit

of focus in venues where back wall reections or noise levels o-site are a concern. It represents the

soft edges of the systems coverage. If the user is required to obtain maximum throw and SPL to the

back of the venue, the green aiming line of the top enclosure of the array should be used as the top of

coverage. This will have the side-eect of some wasted energy above the coverage area and some loss

of coverage down front so take this into account when designing.

SPL – This toggles on or o the entire SPL routine in Resolution. It may seem obvious that the SPL

routine is why you are using the software to begin with but this option allows you to turn it o while

you are in the process of building both the venue and the intended arrays saving valuable RAM

energy. The number crunching that takes place in the routine can be intense!

SPL Map – Toggles on or o the SPL mapping feature. The surfaces themselves will continue to plot

the SPL for the design but the overall vertical and horizontal map will be bypassed. Again, this is a

time-saving and RAM-saving feature.

Contour Lines – In each design, it is possible to show vertical and horizontal isocontours dened in

various stages of SPL loss. These plots will overlay on the SPL map and are useful to clarify the shape of

the coverage and how well it matches the audience geometry. The contours can be viewed even when

the SPL mapping has been toggled o.

Frequency Response – Once frequency / SPL points have been dened (more on this later), the

frequency response at each location can be viewed. This feature, like all features in Resolution, works

in an anechoic environment and does not include any reective data. Consider each of the points as

virtual measurement mics giving accurate SPL and equalization data.

Array Pane – Toggles on or o the Array Pane within the design work area (allowing more visual space

for the other two panes)

Venue Pane - Toggles on or o the Venue Pane within the design work area (allowing more visual

space for the other two panes)

Property Pane - Toggles on or o the Property Pane within the design work area (allowing more visual

space for the other two panes)

Insert Menu

The “Insert” dropdown menu provides to simple functions:

Array – This will automatically launch the Array Assistant feature within the software providing the

user with an extremely fast and accurate way of placing arrays.

Floor – This will place a new oor within the model. Be advised that this is a “new” oor and not an

addition to a currently implemented oor already placed within the model.

Options Menu

Like the View menu, the Options menu has many powerful features that enhance the experience of

using the Resolution software.

Automatically Check for Updates – By selecting this feature, Resolution will periodically check for

new, revised versions of the software when connected to the internet. The user will be prompted

when there is a newer version and you will have the option to install or not install the newer version

Temperature And Humidity – This opens up a congurable box that allows

the user to include the current temperature and humidity into the design using

EAW’s very powerful air-loss calculations. These values will vary the overall

outcome of the mapping so be certain that the values are correct.

Without Air Absorption – By default, Resolution plots its SPL mapping data with the inclusion of air

loss. This is only practical as sound is always aected by air over distance. However, if one should want

to see the dierence that air loss is making on the design, the feature can be disabled by toggling it o

here.

SPL Interpolation – This allows the user to set the resolution of the SPL mapping. Three choices are

oered from fastest to best. Fastest takes less time to calculate but provides plots that are more coarse.

These are ok for rough calculations but should not be relied upon for the nal design review. Normal

provides better resolution of the mapping but is still somewhat coarse. Best is the option of choice for

obtaining extremely accurate mapping. The trade-o being that it takes longer to crunch the numbers

than the other two options.

Side View Contour Lines – When the option to see contour lines has been selected, the user will have

three choices as to how these contours will be viewed in the section.

Top View Contour Lines - When the option to see contour lines has been selected, the user will have

three options as to how these contours will be viewed in the plan.

Design Factor – This is the most important feature within Resolution and every care should be

taken that it is set accurately. This feature modies the limits of the mechanical rigging and there

are four options available (5:1, 8:1, 10:1, 12:1). The design factor that you decide to use should match

the acceptable level of safety in your particular country. In the United States, a 5:1 design factor is

generally considered to be acceptable but other countries such as Germany are much higher at 10 and

even 12:1! Using higher ratios in the design factor will limit the number of enclosures one can hang in

an array and also limit the tilt both up and down that one can achieve. The option opens a dialogue

box that reviews the safety considerations one should be aware of before altering the design factor.

SI Units – Selects the Metric option for entering all data in Resolution

US Units – Selects the Imperial option for entering all data in Resolution

Cartesian Venue Measurements – Used when measurements are based on known points of

intersection in width, height and length. Recommended when working from scale drawings and for

venues where heights of objects are known relative to one another.

Polar Venue Measurements – Used when measurements are based on height and distance of the

starting point of an object where an objects length and angle (if known) to an end point are known.

Recommended for measurements made in a venue where relative measurements are unknown but

start and end points of individual objects are.

Laser Venue Measurements – Measurements are relative to a single point in a venue dened as

a beginning and end point of an object in angle and distance from the same point of observation.

Recommended when a laser range nder and inclinometer are used together to collect data.

Max SPL – SPL is measured as a maximum loudness for any given frequency.

Flat SPL – SPL is measured as the highest loudness level where all frequencies can be sustained at the

same output level

Tools Menu

Under Tools, you will nd the following:

Inventory Manager – A helpful tool that allows you to tailor the

software to match your existing equipment roster. By selecting or

deselecting from the inventory menu, the software will omit products

which you do not own. Any products highlighted in blue in the

inventory manager list are hyperlinks to the EAW website for product

pdf’s (requires internet hookup). The version number of the product

in Resolution is to the far right. Clicking on the version number will

open a box detailing “release notes” for that particular product. To add

or remove a product from Resolution, check or uncheck the circle to

the left of the Inventory Manager menu. All products remain within the

software but do not show themselves in any menus.
