The Most Accurate Prediction Program Just Got More Powerful
Version 1.1.3 Release Notes
The LYON-WXT has been added to the list of Flown Loudspeaker Systems. Up to two LYON-WXT can be selected beneath a LYON-W.Meyer Sound’s LYON-WXT extends the vertical coverage of the LYON-W line array loudspeaker for use as downfill at the bottom of LYON or LEO-M+LYON arrays. LYON-WXT has the same horizontal dispersion and acoustical properties as a standard LYON-W but has greater vertical dispersion, so fewer elements are needed to achieve wider vertical coverage in large, multi-level venues. Available splay angles for LYON-WXT are 8–15 degrees (compared to 0–9 degrees for LYON-W), allowing LYON-WXT to cover nearly twice the vertical area as LYON-W. LYON-WXT is particularly effective when used for downfill at the bottom of extremely curved arrays, such as those used near or directly above the stage for in-the-round arena coverage. LYON-WXT can also be used for installations that cannot use frontfill loudspeakers. LYON-WXT integrates cleanly into LYON arrays without transition hardware. LYON-WXT is available as a factory installed option or as a field upgrade for existing LYON-W loudspeakers
Version 1.1.2 Release Notes
When comparing product capabilities (including SPL and headroom) in MAPP XT, one must consider how loudspeaker arrays work when the individual elements are combined into a system. Before LEOPARD’s development Meyer Sound line array elements would individually exhibit an equal magnitude response with pink noise as the stimulus. With LEOPARD, a new paradigm has begun where the complementary array EQ is applied inside the loudspeaker. To compare SPL accurately, Meyer Sound created “Array EQ” Loudspeaker Types in MAPP XT. These specific array EQ products were added to the available product options for specific Flown Loudspeaker Systems:
- MINA Array EQ (Hanging from MTG-MINA or MTF-MINA from 500-HP)
- M’elodie Array EQ (Hanging from MG-M’elodie or from 500-HP)
- MICA Array EQ (Hanging from MG-MICA or from 600-HP)
- LYON Array EQ (Hanging from MTG-LYON)
- LEO-M Array EQ (Hanging from MTG-LEO)
Version 1.1 Release Notes
This release of MAPP XT includes Rigging Factor of Safety for LEOPARD Family Products, Gradient Subwoofer Array support for 900-LFC, and transition frame support for LEOPARD. Pink and B-Noise data has been added for the following loudspeakers: UPA-1P, MM-10AC, 600-HP, UMS-1P, and USW-1P.

- Enhancement and fixes to Flown Loudspeaker System
Version 1.0 Release Notes
- B-Noise SPL Data:Because a single input type cannot reveal all the headroom capabilities of a loudspeaker on its own, MAPP XT displays information on available headroom using different input sources. A simple SPL number on a datasheet does not reflect the essential characteristic of highly linear systems: that they do not change their sound when the level is increased. The Headroom Tab in the MAPP XT Measurement Viewer shows B-Noise for several Meyer Sound Products. With the ability to store and recall traces in MAPP XT, you can view combined systems with this new data, and verify that system designs have sufficient headroom. More products with B-Noise data will be included in future versions of MAPP XT.
- Gaussian Variability Enhancement AlgorithmTo give better simulations of real world measurements, a new algorithm has been added to MAPP XT that simulates the small natural variability in our loudspeakers. Before this algorithm was added, all loudspeakers of the same model in MAPP used the same measured complex polar data set. This had the unintended effect of creating infinite nulls (for example), which never happens in physical measurements. While Meyer Sound loudspeakers are extremely consistent, they are not perfectly identical. To simulate actual measurements, the algorithm adds a slight (-/+ 0.25 dB) normally-distributed (Gaussian) variation to loudspeakers of the same model. There is no possibility of the algorithm producing incorrect results, but since the algorithm is applied each time you predict, there will be slight differences between predictions.
- Gradient Subwoofer Array Configuration Tool: 1100-LFC and 500-HP:The 1100-LFC and 500-HP can each be configured in cardioid arrays to reduce SPL behind the loudspeakers. Each loudspeaker’s linearity ensures that cardioid patterns behave accurately, even at very high levels. Cardioid arrays are achieved by placing three units coplanar to each other (in either a ground stacked or flown array) with one unit facing the opposite direction. The output of the reversed loudspeaker cancels the output of the other loudspeakers that is normally present behind the units, while also increasing SPL directed forward. Meyer Sound has provided a tool within MAPP XT to optimally configure gradient subwoofer arrays. Once inserted into the sound field, they can remain a gradient subwoofer array object that automatically assigns the correct delay time for the second processor channel. To override any of these automated settings, the object can be converted to a flown loudspeaker system. Gradient Subwoofer Arrays are saved in the MAPP Project File.
- Auto-Splay for LEO Family Flown Loudspeaker Systems:The Auto-Splay feature estimates optimum splay angles for single flown LEO-M, LYON, and LEOPARD loudspeaker systems. Auto-Splay is only available when a single flown loudspeaker system is selected along with a single Listener Plane. A Listener Plane is a converted Architectural Visual Aid that represents an audience area facing the loudspeaker system. Listener Planes can be divided into one or more reference zones. Once the loudspeaker system is selected, along with the Listener Plane, choose Auto-Splay to estimate the optimum splay angles for the system. When the single flown loudspeaker system is selected along with the Listener Plane, the Auto-Splay feature can be used to obtain array starting angles.
- Store and Recall Traces:In the Measurement Viewer window, live traces can be stored and recalled to 4 individual memory slots in Headroom, IFFT (SIM), and Frequency Response (SIM) modes. The memory trace plots display in different colors along with the live trace in all available measurement modes. The traces can be displayed or hidden on demand. These traces are only stored for the active MAPP XT session. They are not stored in the MAPP Project File.
- LEO Family Products:LEO-M, LYON-M, LYON-W and LEOPARD are available in Flown Loudspeaker Systems.
- 1100-LFC:1100-LFC is available in Flown, Gradient, Individual, and Ground Stacked Loudspeaker Systems.

- Phase Trace (Result Mode):In the Measurement Viewer window, the frequency response shows the phase trace when “Result” mode is selected. Using the Auto-Set Delay button inserts delay on the source signal so the relative time between the source signal and the measured signal is zero.
Rigging Safety Analysis has been added to MAPP XT to provide more detailed information regarding the calculations for LYON and LEO Flown Loudspeaker Systems:With a given array configuration, you can choose an analysis type that indicates whether or not the desired array configuration will be OK to hang. When you insert a Flown Loudspeaker System using the MTG-LYON, the rigging Factor Of Safety feature is enabled and analyzes the configuration as you add or subtract LYON elements and change array angles. In future releases of MAPP XT, the Reference Pickup Point Options box will be changed to specify the available top grid (bumper) pickup points that are supported by the rigging hardware. They will be disabled for products (i.e. LYON-M and LYON-W) that are not using this additional analysis feature. If the configuration exceeds the mechanical load limits, a warning is displayed in the edit loudspeaker system properties:
- Rated load capacities of the Meyer Sound rigging assembly for different splay angle settings are based on testing performed by an independent testing agency, and on safety limit analysis performed by an independent structural engineering firm. The ratings apply to the Meyer Sound rigging only. You are responsible for selecting the safety factor required by local law for your installation, and for determining the adequacy of supporting structure “above the hook. PERMANENT INSTALLATIONS MUST BE CERTIFIED BY THE ENGINEER OF RECORD FOR WIND AND SEISMIC LOADING.
- LIMITATIONS AND DISCLAIMER:The safety limit analysis provided by this program does not apply, and may not be relied upon, if your loudspeaker system (1) has been improperly installed or maintained, (2) the rigging or loudspeakers of your system have been damaged prior to installation, (3) your indicated configuration of the system has been altered, (4) any weight has been added to your indicated configuration, or (5) your system is in an outdoor venue and remains installed during strong wind conditions. MEYER SOUND ASSUMES NO RESPONSIBILITY FOR ANY PART OF AN INSTALLATION “ABOVE THE HOOK” OR WHERE ANY OF THE FOREGOING LIMITATIONS APPLY.
