MAPP Online Pro 2.8 INTRODUCTION: Meyer Sound MAPP Online® Pro 2.8 MAPP Online Pro 2.8 is a powerful, cross-platform software application for accurately predicting the coverage pattern, frequency response, impulse response and maximum SPL output of single or arrayed Meyer Sound loudspeakers.
MAPP Online Pro 2.8 NOTE: MAPP Online Pro is upgraded continually to add new Meyer Sound products to the database and enhance user features. All upgrades are downloaded automatically when connected to the internet and launching the program. The MAPP Online database includes nearly all current Meyer Sound products, including the M Series products and their corresponding rigging hardware. To view the Release Notes for the latest version, select Help > Contents within MAPP Online Pro.
MAPP Online Pro 2.8 Getting Started MAPP Online Pro is a Single Document Interface (SDI) software application with a familiar and intuitive user interface. NOTE: Depending on system resources, multiple instances of MAPP Online Pro can run simultaneously. MAPP Online Pro’s commands and corresponding shortcut keys are accessible via the menu bar at the top of the workspace. The workspace is composed of two windows: the main application Sound Field window and Virtual SIM®.
MAPP Online Pro 2.8 Pop-Up Menu The pop-up menu (Figure 2) is a quick way to get to the most frequently used program tools; it will change based on the selection and creation of objects. In Windows, you can access this menu by right-clicking with your mouse. Figure 2. The pop-up menu provides access to MAPP Online tools Tip: If you’re running MAPP Online Pro on an Apple Macintosh computer, hold the control key down while clicking the mouse to launch the pop-up menu.
MAPP Online Pro 2.8 Supported File Types MAPP Online works with three types of files: n Extensible Markup Language (XML), a condensed form of SGML (Standard Generalized Markup Language), is MAPP Online Pro’s default project file format for storing and saving MAPP data. n Comma Separated Value (CSV), a simple text file containing data stored in database fields separated by commas. This is a format used by the standard version of MAPP Online. It can be opened but not saved using MAPP Online Pro.
MAPP Online Pro 2.8 MENUS AND FUNCTIONS Project Properties You can create and save project-specific data to a MAPP Online Pro project file using the Project Properties dialog. A project contains the following information: n Project Name n Venue n Designer n Date n Notes To modify project properties, perform the following steps: 1. Launch MAPP Online Pro. A default, blank project is created for you automatically. 2. From the File menu on the menu bar, choose Project Properties. Figure 3.

MAPP Online Pro 2.8 Saving a Zip Archive MAPP Online Pro makes it easy for you to store extended project information by giving you the option to save your project as a zip file. Saving to a zip file will export the project file as well as an imported DXF file being used as an overlay in the project. The files are automatically written to a zip archive which you can later open with MAPP. The ZIP file also contains a comment which includes the Version Number and the Locale which created it.
MAPP Online Pro 2.8 Export Graphics You can save Sound Field Images to a Web-ready image format or to other specialized image formats by choosing Export Graphics... from the File menu in both the Sound Field and Virtual SIM windows. The five types are postscript (PS), EPS, JPEG, PNG and BMP. To create an EPS, PS, JPEG, PNG, or BMP file of the sound field, perform the following steps: 1. From the File menu, choose Export > Export Graphics… The Export dialog appears. 2.
MAPP Online Pro 2.8 Selecting Objects The following three sections give basic instructions on how to select, move, and rotate objects within the MAPP Online Sound Field. Methods for placing loudspeakers, arrays, microphones, and architectural elements into MAPP Online will be detailed later in the manual (see the sections on Loudspeaker Placement, Microphone Placement, and Visual Aids).
MAPP Online Pro 2.8 6. If any part of the selection rectangle crosses over an object in the workspace, that object will be selected and shown in dashed lines (Figure 10). Figure 10. Selecting objects by crossing object with a selection rectangle 7. To de-select an object or group of objects, left-click in a blank area of the screen. Moving Objects Once selected, objects can be moved individually or in groups. 1.
MAPP Online Pro 2.8 Figure 11. Loudspeaker is selected and moved from original location. Rotating Objects Objects in MAPP Online Pro can be rotated individually or in groups, as follows: 1.
MAPP Online Pro 2.8 3. To rotate the loudspeaker or group, move the cursor arrow anywhere in front of the loudspeaker or group, then click and hold the left mouse button. 4. While holding the mouse button, move the mouse to rotate the loudspeaker icon(s). 5. The degree of angle change from the current loudspeaker position will be show numerically next to the cursor (Figure 12), with the current position of the loudspeaker being designated as 0 degrees. Rotate button Figure 12.
MAPP Online Pro 2.8 NOTE: Left-clicking on the workspace while in the Rotate mode will move the icon (and the center of rotation) to the position where the cursor is located. To undo this movement if done accidentally, either: a) click again on the Rotate button at the top right of the sound field (or on the Select, Zoom, or Architecture buttons); or b) right-click in the sound field and select the same items within the menu as in the suggestion above.
MAPP Online Pro 2.8 Tip: Using Control "–" on the computer keyboard has the same effect as Zoom Out, reversing the zoom process one step at a time. Alternately, placing the cursor anywhere in the sound field, holding down the Alt key, and left-clicking the mouse will accomplish the same Zoom Out task. Figure 13. Zoom features in the MAPP Online Pro sound field Center Line Each loudspeaker in MAPP Online Pro has a center axis to help you place and set the output direction of the loudspeaker.
MAPP Online Pro 2.8 MG-MICA Array Zones MAPP Online Pro displays a wealth of information related to the MG-MICA rigging system: Location of the MICA’s array center of gravity. This information is critical in the determination of the load rating of the MG-MICA. Total weight of the array. Distribution of the load on the front and rear points. Height and depth of the array.
MAPP Online Pro 2.8 CAUTION: Using a bridle leg shorter than the recommended length for each configuration will reduce the load rating and may damage the MG-MICA grid. CAUTION: Always use properly rated rigging hardware. The use of 3/4" shackles for the MG-MICA grid’s pick-up points is recommended. With the use of transition accessories, you can also integrate other M Series loudspeakers, to form combined arrays.
MAPP Online Pro 2.8 Table 1.
MAPP Online Pro 2.8 Flown Loudspeaker System: 1. Open the dialog Insert > Insert Flown Loudspeaker System and create the array below the MG-MICA grid. Select the MICA Forward or MICA Rearward grid position, depending on whether more downtilt or more uptilt is desired as a starting place. Insert the necessary quantity of loudspeakers, set the initial splay angles, and set the initial grid height and positioning. If necessary, consult the MG-MICA Assembly Guide for further information. 2.

MAPP Online Pro 2.8 256 colors (High Resolution) Figure 15.
MAPP Online Pro 2.8 Measurement Units Choose Settings > Measurement Units to change the measurement units. Distance in meters and feet may be selected, as well as in centimeters/millimeters and inches. Settings are also available for weight in kilograms and pounds (and fractions thereof), temperature in Fahrenheit, Celsius, and Kelvin as well as pressure units in millibars, pascals, and kilopascals. The distance units are shown on the X and Y axes of the sound field window.
MAPP Online Pro 2.8 Preferences In addition to the previous options, the following visual tools can also be configured via the Settings menu (Figure 17): n From the Settings menu, choose Background Color to change the background color to white, light gray or black. n Choose Settings > Grid > Coarse to view basic grid lines. Grids are used as a visual aid for positioning loudspeakers and microphones within the sound field. n Choose Settings > Grid > Fine to view grid lines with tighter spacing. Figure 17.
MAPP Online Pro 2.8 The Prediction Plane MAPP Online Professional is a 2D application that makes its SPL predictions using complex, 3D high-resolution polar data. The prediction plane displayed by MAPP Online Pro represents a 2D slice of that 3D data. The following section and illustrations will show the types of predictions that can be made with MAPP Online Pro, and how to “visualize” and interpret the resulting SPL maps within the sound field.
MAPP Online Pro 2.8 Figure 18. Isometric view of three MSL-4 loudspeakers showing a representation of the 2D prediction plane When making sound field predictions for horizontal arrays of conventional loudspeakers, a vertical prediction of that same array is not possible. Only one column or a single loudspeaker within one row of an array can be predicted.
MAPP Online Pro 2.8 As a representation of a vertical 2D prediction plane in MAPP Online Pro, Figure 19 shows the predicted loudspeaker and the other MSL-4 loudspeakers (in red) that cannot be represented in a vertical prediction of a horizontal array that contains three MSL-4 loudspeakers. To make this prediction in MAPP Online, a single MSL-4 would be placed into a blank sound field in a vertical orientation. Figure 19.
MAPP Online Pro 2.8 Conversely, a horizontal sound field prediction of a vertical array is not possible. Only one row, or the top loudspeaker, will be predicted. A vertical array includes multiple loudspeakers that are stacked or linked on top of each other to form columns. This array may contain loudspeakers of different types, such as subwoofers, the main full-range loudspeakers, and smaller or more specialized ones for front fill.
MAPP Online Pro 2.8 Figure 21. Only the first row, or top loudspeaker, can be predicted in the horizontal plane in a vertical array. The prediction plane can be used as a floor plan or elevation. Each of the four surfaces can be enabled with materials from the surface materials library in the prediction plane dialog. By enabling these surfaces, a floor, ceiling, or walls with varying degrees of reflectivity or absorption can be entered into the sound field predictions.
MAPP Online Pro 2.8 Surface enabled, solid line Surface not enabled, dashed line Figure 22.
MAPP Online Pro 2.8 Using MAPP Online Pro Over time, users of MAPP Online Pro will develop their own methods of making predictions for their installations, concerts, and theatrical productions. The following basic approach is one method that has lead to successful results. Predict the horizontal (floor plan) layout first to determine the number and location of line arrays, side fills, or columns of conventional full-range loudspeakers required for coverage in the venue.
MAPP Online Pro 2.8 Each 16 channel processor has a unique hardware address and each project can have up to 80 outputs. The microphones are also organized by their own"switcher" hardware address and each project can use up to 24 microphones. This architecture is also utilized in the SIM 3 Audio Analyzer. Each mic switcher contains unique audio inputs. Therefore it must have a unique network address in order for the SIM-3022 analyzer to select the proper mic channel for measurement.
MAPP Online Pro 2.8 Figure 22b Device Configuration window with user defined processor output settings in MAPP Online Pro Loudspeaker Placement There are four placement methods for loudspeakers in MAPP Online Pro. The traditional placement for an individual loudspeaker uses the geometric center of rotation during measurement (GCRM). The other three methods use the Rig Point position of the physical rigging hardware or the top or side of the loudspeaker enclosure.
MAPP Online Pro 2.8 Insert Individual Loudspeaker: Geometric Center of Rotation during Measurement (GCRM) Insert Flown Loudspeaker System: Front Rig Point (X=8, Y=20) Figure 23a & 23b.
MAPP Online Pro 2.8 Insert Horizontal Loudspeaker System: Rear Rig Point (X=5, Y=16) Insert Ground Stacked Loudspeaker System: Front Rig Point (X=5, Y=0) Figure 23c and 23d. Horizontal and vertical gound stacked loudspeaker placement methods in MAPP Online Pro NOTE: When using Ground Stacked Systems be aware that the table in the Insert Ground Stacked Loudspeaker System dialog will still build from the top down. The array will build from the ground up as shown in Figure 23d.
MAPP Online Pro 2.8 3. Here you can edit properties, e.g., the loudspeaker’s type, angle, and X and Y coordinates within the sound field. For now just click OK. A new loudspeaker is created at the X and Y coordinates representing 10 meters/10 meters (or the equivalent in other measurement units) by default. Figure 24. The Insert Loudspeaker dialog box NOTE: The default loudspeaker in the Insert Loudspeaker dialog box when opening a New Project is the CQ-1 Wide Coverage Main Loudspeaker.
MAPP Online Pro 2.8 Figure 25. Repositioning loudspeaker in the Loudspeaker Properties dialog box 10. Click OK to see your changes. NOTE: The Solo function is similar to having an RMS module inside the selected loudspeaker's amplifier. Clicking the Solo button will solo the loudspeaker for predicting, muting all other loudspeakers except for the one you have soloed. You can solo more than one loudspeaker at a time.
MAPP Online Pro 2.8 Changing the Origin in the Sound Field By default, the prediction plane of the sound field has its 0,0 origins begin in the lower left corner. In some circumstances, when matching the measurements within a venue, the MAPP Online Pro user will desire to change the location of those origins, on the X or Y axis (or both). Use the following procedure to relocate the origin within the sound field. 1. From the main menu, select Settings > Prediction Plane, and click to open the dialog box. 2.
MAPP Online Pro 2.8 Sound Field Prediction The main purpose of MAPP Online Pro is to determine and adjust the placement of (typically multiple) loudspeaker systems in order to achieve the best coverage of the listener areas in a venue. The sound field prediction is at the heart of its capabilities. To make a prediction, click the Predict button in the tool bar at the top left of the program.
MAPP Online Pro 2.8 Changing the Center Frequency In Figure 27, the tables at the bottom of the sound field report a number of parameters used for the prediction. The center frequency listed in the tables is the frequency that was used for the prediction that appears in the sound field. From the Settings menu, choose Frequency Range or click on the relative bandwidth and/or frequency drop-down box at the top of the main window (next to the Predict button) to select a different bandwidth and frequency.
MAPP Online Pro 2.8 Selecting Loudspeakers for SPL Predictions By default, selecting Predict will perform SPL calculations for all of the loudspeakers within the sound field. However, the user can choose to predict selected loudspeakers – a subset of the total – in order to view the effect and coverage of various loudspeakers within the sound field. Use the following procedure to perform predictions for some but not all of the loudspeakers in the sound field: 1.
MAPP Online Pro 2.8 Figure 28.
MAPP Online Pro 2.8 Tip: To clear the sound field of the current color SPL map so that the placement of the loudspeakers and microphones can more easily be seen, use the following techniques. When a prediction has been done using all of the loudspeakers within the sound field, choose another frequency from the frequency pull-down menu and the prediction will clear. When a prediction has been done using a selected subset of loudspeakers, choose one of those speakers and perform the previous procedure.
MAPP Online Pro 2.8 Microphone Placement MAPP Online uses pure omni virtual microphones for measuring broadband SPL. While only one microphone can be used for any given prediction, multiple microphones may be placed anywhere in the sound field. To insert a new microphone: 1. Click Insert Microphone... from the Insert menu. The Insert Microphone dialog box appears (Figure 30). Figure 30. The Insert Microphone dialog box 2. Click OK.
MAPP Online Pro 2.8 To edit the properties of a microphone, select the microphone, then choose Edit Microphone from the Edit menu or use the right-click menu. You can edit the microphone’s position, rotation, orientation and name (Figure 31). Figure 31. The Microphone Properties dialog NOTE: The rotation of the microphone has no effect on the Virtual SIM trace or other measurement calculations, since it is functioning as a perfect omnidirectional mic at that point in the virtual prediction space.
MAPP Online Pro 2.8 Project and Loudspeaker System Reports To create a MAPP Online Pro project report, perform the following steps: 1. From the Tools menu, select Project Report. The Save Project Report As dialog appears (Figure 32). Figure 32.
MAPP Online Pro 2.8 2. Type a descriptive name then click Generate Report to save the current report or Cancel to proceed without saving. An HTML page will be generated that includes references to images of the sound field prediction, Virtual SIM panels if present, a list of your loudspeakers, microphones and other project properties (Figure 33). Once this page is created, it can be opened up for viewing and printing in a browser window. The HTML output is compliant with XHTML 1.0. Figure 33.
MAPP Online Pro 2.8 To create a MAPP Online Pro loudspeaker system report for a particular array or subset of a larger system, perform the following steps: 1. Select a loudspeaker system by left-clicking on it when the Select button is highlighted at the top of the sound field. This report may only be done for one loudspeaker system or array at a time. 2. From the Tools menu, select Loudspeaker System Report (Figure 34). Figure 34.
MAPP Online Pro 2.8 3. The Loudspeaker System Report Preview will appear (Figure 35). You can type additional notes then click OK to proceed to the Save Loudspeaker System Report As dialog box. Figure 35. The Loudspeaker System Report Preview dialog box 4. Type a descriptive name then click OK to save the current report or Cancel to proceed without saving. An HTML page will be generated that includes only the information about the currently selected loudspeaker system.
MAPP Online Pro 2.8 Virtual SIM MAPP Online Pro’s Virtual SIM functionality provides immediate acoustical measurement feedback. To use Virtual SIM, perform the following steps: 1. Add a new microphone to the sound field (see the previous section). 2. Select the microphone and move it anywhere in the sound field. 3. When you release the mouse button after placing the microphone, the Virtual SIM window automatically appears after contacting the MAPP Pro Server.
MAPP Online Pro 2.8 NOTE: The A and C-Weighted average and peak SPL calculations appear in the table at the bottom of the Virtual SIM window; full-spectrum average and peak SPL appear when available. SPL information will not be available if a processor filter is engaged. Because all loudspeakers are scanned at peak power, a boost at any frequency will engage the limiters which will affect the overall frequency response.
MAPP Online Pro 2.8 Dynamic Update (ALWAYS ON) Virtual SIM’s Dynamic Update feature speeds up the process of microphone placement, allowing you to receive Virtual SIM updates on the fly without having to use the predict button each time. Dynamic Update all but eliminates the need to wait for the creation of the sound field. For example, Figure 37 shows a single horizontal UPJ-1P with a microphone at 20 meters away. The same microphone was then moved using the cursor to the approximate coordinates (15,2).
MAPP Online Pro 2.8 Off-axis microphone placement Figure 38. The same sound field prediction moved off-axis after Dynamic Update (also see Figure 37) If a microphone is muted and then moved to another location, a Virtual SIM prediction will not occur. It needs to be unmuted in order to run a Virtual SIM prediction; if a microphone is muted and a prediction is executed from the main sound field window, the prediction will only produce a sound field pressure map.
MAPP Online Pro 2.8 Figures 39 and 40 show the Virtual SIM results of an on-axis and off-axis microphone placement. Figure 39. A simple on-axis Virtual SIM prediction High frequency loss due to placement microphone approaching end of loudspeaker coverage Figure 40.
MAPP Online Pro 2.8 Saving and Exporting You can save Virtual SIM traces to a Web-ready image format or to other specialized image formats by using the Export Graphics... from the File menu in the Virtual SIM window (Figure 41). Figure 41. Export Graphics...
MAPP Online Pro 2.8 MAPP Online Pro supports the following Virtual SIM file formats: n JPG (or JPEG) — the Web-standard Joint Photographic Experts Group image format n EPS — creates a vector image n PS — creates a standard postscript file n CSV — useful for creating overlaying traces in a spreadsheet program (found under the Export Data... command] n PNG — Portable Network Graphics, a file format for bitmapped graphic images n BMP — Device Independent bitmapped graphic images Figure 42.
MAPP Online Pro 2.8 VIEW Menu Virtual SIM’s View menu enables you to change the vertical scale from 30 dB per division down to 1 dB per division. For example, to change the vertical scale to 12dB per division, from the View menu choose Vertical Zoom > 12 dB/div (also available from the “right-click” menu). Figure 43.
MAPP Online Pro 2.8 You can also zoom in or out of different frequency ranges in the Virtual SIM trace to get a closer look at peaks and dips. For example, clicking Horizontal Zoom from the View menu (or right-click within the graph) gives you different range options to choose from. Figure 44.
MAPP Online Pro 2.8 Frequency Response To view a frequency response measurement in Virtual SIM, choose the Frequency Response tab. Figure 45. Example of frequency response trace in Virtual SIM There are four viewing options available in frequency response: Room, Processor, Result, and Group. Group is the default which provides the room, processor and result traces together. The output control table along with Galileo processing is available below the graph.
MAPP Online Pro 2.8 When you change parameters of any processor filter, the green line displayed represents the 1/EQ curve. The 1/EQ curve is the inverse of the equalization that would be produced by changes to the processor settings. By matching the 1/EQ curve to the frequency response, you can find a combination of settings that will equalize your loudspeaker(s). Figure 46. Using the virtual parametric filters in Virtual SIM NOTE: The SPL will not be calculated when any one or many filters are enabled.
MAPP Online Pro 2.8 Impulse Response To view an impulse response measurement in Virtual SIM, click the Impulse Response tab. The predicted impulse response will be displayed. The “peak impulse” in the table displays the arrival time of the maximum peak. This value is used in conjunction with the estimated sound speed to compute the “approximate distance” from the microphone to the loudspeaker(s), also reported in the table.
MAPP Online Pro 2.8 Figure 47. Impulse response graph of single loudspeaker (or aligned group) Figure 48.
MAPP Online Pro 2.8 The Trace-Value Cursor The trace-value cursor shows the relative SPL of the Virtual SIM trace at any frequency. It can also be used within the impulse response measurement to show the exact time and relative amplitude of the response. To engage the trace-value cursor, click in any Virtual SIM measurement window within the graph lines. Hold down the left mouse key and move the cursor from left to right to see the tracking along the trace.
MAPP Online Pro 2.8 Loudspeaker Systems Earlier in this User Guide, you learned how to create and place a single loudspeaker, which is useful for predicting the behavior of individual Meyer Sound loudspeakers. However, the real power of MAPP Online Pro is its ability to work with entire loudspeaker systems — from single components to individual arrays to the interaction between all loudspeakers in the system. To create a loudspeaker system, perform the following steps: 1.
MAPP Online Pro 2.8 3. The Insert Loudspeaker System dialog appears. The default system presented uses M'elodie Loudspeakers with the MG-M'elodie Top Grid(Bumper) with no angles set. 1 4 3 2 5 7 6 8 9 10 11 12 13 14 15 18 19 20 16 17 21 1. Direction of loudspeaker system; 2. Rigging point on loudspeaker enclosure or rigging element; 3. Rig point position on Sound Field window; 4. Angle of first Element; 5. Name of Loudspeaker System; 6. Center Line of loudspeaker System; 7.
MAPP Online Pro 2.8 NOTE: The maximum array size is set to what the related top grid will hold (Refer to the operating instructions for individual top grid specifications). 6. Click on the Model Name column in the table. A drop-down box will appear allowing you to select the model name of a loudspeaker or rigging accessory in the array. Clicking on the first model name in the list opens up the full list of possible rigging hardware and loudspeaker models available in MAPP Online Pro.
MAPP Online Pro 2.8 e.g., 1/1 octave at 2 kHz and then predict at 4 kHz (Figure 51). Center frequency at 2 kHz Center frequency at 4 kHz Figure 51.
MAPP Online Pro 2.8 Changing the Environment Every venue has its own unique environmental “fingerprint.” MAPP Online Pro allows you to change altitude, temperature, barometric pressure, and relative humidity to more closely factor in that fingerprint. These controls are also found in the LD-3 and Galileo 616. Refer to the Operating instructions for the LD-3 for further details on atmospheric correction.
MAPP Online Pro 2.8 The following steps will walk you through changing environmental settings to demonstrate the difference that the “fingerprint” can make: 1. Begin a new Project. 2. Insert the default loudspeaker. 3. Insert a microphone at a distance of 20 meters on axis with the loudspeaker. 4. From the Settings menu, choose Natural Environment. 5. Adjust the Temperature, Pressure and Relative Humidity sliders to taste.
MAPP Online Pro 2.8 Changes in the response curve Figure 54.
MAPP Online Pro 2.8 Visual Aids MAPP Online Professional uses two types of visual aids: Architectural and Multi-Level. Architectural Visual Aids Architectural visual aids enable you to create representations of walls or surfaces located within the prediction plane. This type of visual aid is transparent and is not made of any specific material. To add an architectural visual aid, do the following: 1. From the Tools menu, choose Architecture. 2.
MAPP Online Pro 2.8 Figure 55. Insert Architectural Visual Aid into sound field NOTE: To move an architectural visual aid line that you have drawn in the sound field, while in the Select mode place the cursor over the desired line and left-click. Selection boxes will appear at each end. The line can now be moved while holding the left mouse button by moving the mouse up, down, and side-to-side. The angle cannot be changed except within the Insert Architectural Visual Aid dialog box.
MAPP Online Pro 2.8 Multi-Level Visual Aids The Multi-Level visual aid was developed to assist in creating section views more quickly when time is scarce. It works well when utilized with a range finder and inclinometer; you can input the location results from physical measurements and the Multi-Level visual aid tool will connect the two points together.
