- Page 2 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.
- Page 3 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.
- Page 4 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.
- Page 5 Export EASE File – This feature will create a “single-balloon” file 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 file that is already pre-calculated by Resolution and hence only needs to process a single entity! Create PDF –...
- Page 6 SPL – This toggles on or off 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 off while you are in the process of building both the venue and the intended arrays saving valuable RAM energy.
- Page 7 Frequency Response – Once frequency / SPL points have been defined (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 reflective data. Consider each of the points as virtual measurement mics giving accurate SPL and equalization data.
- Page 8 SPL Interpolation – This allows the user to set the resolution of the SPL mapping. Three choices are offered from fastest to best. Fastest takes less time to calculate but provides plots that are more coarse.
- Page 9 Design Factor – This is the most important feature within Resolution and every care should be taken that it is set accurately. This feature modifies the limits of the mechanical rigging and there are four options available (5:1, 8:1, 10:1, 12:1).
- Page 10 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.
- Page 11 Auto-adjust SPL Range – Allows the user to match the SPL mapping to the capabilities of the products being displayed on-screen. Check For Updates – By default, the Resolution software will check automatically for updates to the software if the computer is connected to the internet. The user can also command for a check of recent software updates by clicking on this feature.
- Page 12 Building a Venue Here are the steps to building a venue within Resolution: 1) Select the type of measurement data you are going to use to build the surfaces (Cartesian, Polar, Laser). We have selected Cartesian for this example. Using Cartesian measurements assumes that you have access to room drawings with accurate depth, height and width dimensions for the venue.
- Page 13 Rake Now that we have a single floor surface, we should look at attaching a rake to it as this is fairly common for most theaters in North America. 1) Use the + button to the right of the floor we have just built. This will drop in a rake that attaches itself to the end of the floor you have just built but the data points will of course need to be modified.
- Page 14 If there is a free-standing FOH location within the venue, it is a good idea to position it accurately. Resolution may modify the aiming of the system slightly to account for the FOH position when the user decides to use “Array Assistant. ”...
- Page 15 Width of the venue. Enter the width of each surface here. (Currently, Resolution is limited to absolute width measurements. Fan-shaped and asymmetrically shaped rooms are not currently possible but we are working on it.)
- Page 16 Storing a Venue If you are happy with the design and it is a venue that you may have to do repeatedly but with different loudspeaker arrangements, you can save the room data as its own file. 1) In the bottom left corner of the venue tab, you can click on “Save Preset”. This will allow you to give the venue a name and store it in a folder of your choosing.
- Page 17 When creating a new Resolution file, clicking on the array tab will display the Array Assistant within the lower left corner of the “array” panel. Subsequent arrays being placed with AA will require the user to click on the “Insert”...
- Page 18 6) As with the top element of the array, the bottom element may also have a variety of “Greybox” DSP settings available to it based on the size and / or configuration of the array. The drop down menu under “Bottom” will reveal the choices available to you. This insures that any mapping done for a particular loudspeaker / Greybox choice will be accurate in the modeling.
- Page 19 11) Front splays may also be selected. By default, the software has this feature turned off. Opening the fronts of EAW line array enclosures is possible but not highly recommended. Best results are obtained when the fronts are tight together but there are occasions when audio triage is necessary either to cover the entire audience due to an insufficient number of enclosures on hand or to try and split an array to miss reflections from a balcony face, etc.
- Page 20 Storing an Array As with the venue, the array(s) itself can also be stored independently from the venue. This is useful if the there is a defined set design where the same arrays will always be used but the venue will change from show to show. It allows the user to plot all of the arrays in a defined manner and then drop and modify those arrays in different venues.
- Page 21 100dB and an upper limit of 133dB. No reason, just what I wanted to see. Simply click on the “Auto” button and Resolution will do the rest. The sliders will relocate themselves to the appropriate position but they can still be dragged left or right if you choose.
- Page 22 The top right display will show the mapping criteria. This graph is set for FLAT SPL but remember it can be changed to MAX SPL under the options menu at the top of the Resolution display. Another virtual mic feature available in the “Top View” of the mapping area is the “Virtual Mic Grid”.
- Page 23 By right clicking on any floor surface on the model, three choices of mic grids can be selected from small to large. The user first selects “Add Mic Grid” from the options menu which opens a secondary selection of either 4x6, 6x8 or 8x10 grid. This feature greatly speeds up the process of defining and reviewing an average SPL and Frequency Response measurement for any given floor surface.
- Page 24 Acoustics Let’s move on to even more acoustical data by clicking on the button in the Array Tab work area marked “Acoustics” We will revisit the mechanical aspects of the array shortly. There are a variety of things that can be done here to affect the outcome of the model post Array Assistant.
- Page 25 Again, highly unlikely that we would need to do this in reality but the option is there if you need it. Another feature in Resolution that becomes more valuable as multiple arrays are added to the design is the “Solo” feature.
- Page 26 Even though the switch positions on the NTL only affect the HF (which is ok to mix and match to some degree), it opens the possibility for error that may yield a Resolution map that is undesirable. Use this feature only if absolutely necessary! At the far upper right of the array tab work area, you will find a space called “Array Processing”.
- Page 27 The first array shows no EQ whatsoever The second shows how badly an arrays response can be affected if careful attention is not paid to the independent EQ’s available within Resolution. Again, best to use these features only when absolutely necessary!
- Page 28 Array Geometry Geometric Array Data The button marked “Geometric” will take the user back to an area where he can change the physical attributes of the design. Remember that I had added 3 x KF730 enclosures to the bottom of the KF740 array but up to this point, I haven’t made any changes to those enclosures.
- Page 29 7) The minus (-) button to the far right will delete the corresponding enclosure from the design. In this example I have enlisted the help of a time-saving tool in Resolution called “Clone” Once I have verified that the array is exactly as I want it, I can use the cloning tool to create an exact replica of it.

“Hide Floor”. Once you have seen what you would like to see, simply right-click on the area again and select “Show Floor” to restore the surface to the design. Hiding floors removes it from the calculation. This speeds up the amount of time it takes to display. A time-saving feature in Resolution. - Page 31 Let’s take a look at what is the most important feature of the Resolution software and that is Mechanical Data! To review what was mentioned earlier, we must first set the “design factor” for the mechanical data which can be found under “options”. There will be a review of what design factor refers to and some cautionary notes to review.
- Page 32 Once this happens in Resolution, the array will not be able to be tilted any further. You are asking the software to virtually create an array that practically cannot be accomplished in the real world so it stops you there.
- Page 33 Other Resolution Features Here are a few other helpful features that you will find within Resolution 1) If you right-click in the Array Pane, you will see displayed a choice of either “copy to image” or “copy to CSV”. Copy to image is a screen capture of just the Array Pane that you can now paste in other software such as “Word”...
- Page 34 Right-clicking in the Map Area of the software will allow the user to copy the complete color SPL map to other software as well. This example shows the map being displayed in Microsoft “Word”. Colorful graphics are great for presenting to a prospective client.
