Adding loudspeakers to EASE and EASE JR models is quick and easy. Select the Insert Loudspeaker tool, click on the room model to insert the loudspeaker and then move the loudspeaker to its desired location using the pop up Properties folder that appears. Use the change button to select the desired model from the over 1000 loudspeakers in the database, OK the selection and it’s done.

Note that at the same time you can rotate or turn the loudspeaker, add delay and set its power level.

Loudspeakers are identified in the drawing by either a blue horn symbol or a wire frame drawing or both. The symbol is useful as it shows the insertion point or as it’s commonly called, the rotation point for the loudspeaker. This is the point around which the manufacturer rotated the loudspeaker during its directivity measurements. The wire frame adds realism and is useful when two or more loudspeakers are being arrayed together as it shows any physical interference problems. Either one or both can easily be turned off for appearance reasons.

Aiming the loudspeaker is just as easy as it was to insert it. The most popular method is to look out through the loudspeaker at a display of its directivity pattern imposed on the room. The white cross represents its aiming point can easily be moved to a new location with the Mouse.

Another method uses the -3,-6, -9 dB Isobars method. The purple line represents the aiming point and can be grabbed with the mouse and moved about at will. The red lines are the -3dB points and the yellow lines -6 dB.

Multi loudspeaker arrays can easily be grouped together into a "Cluster". As a cluster, they act a single loudspeaker during simulations and reduce the calculation time. Clusters can also be saved and used again and again in other projects.

Multi loudspeaker arrays can also be turned into an Object. As an Object they can be moved and aimed as a single unit, but perform as individual loudspeakers during simulations. This increases calculation times, but provides a higher degree of accuracy in the near field.

DLL’s (Dynamic Link Libraries) are a new EASE and EASE JR feature. Each DLL is in effect a self contained program that allows users to create line arrays of different sizes (6, 8 or 12 array modules, for example) and configurations (straight, curved and "J", for example) and use them as if they were a single loudspeaker.
