Speaker Array |
Audio/Video |
Large venues require the use of speaker arrays, which consist of speakers stacked in a column and topped by a bumper (top mounting bracket). Up to three different types of speakers can be included in an array. The speakers can each be tilted differently to provide maximum audio coverage for the audience.
To insert a speaker array:
Click the tool and the insertion modes.
Click to place the object in the drawing, and click again to set the rotation.
The first time you use the tool in a file, a properties dialog box opens. Set the default parameters.
The speaker array properties can be edited later from the Object Info palette. To edit the array, select the bumper. Individual speakers can be selected and certain parameters can be set independently, but since the speakers are controlled by the array, many of their parameters are not available (see Inserting speakers for parameter descriptions). Some information from parameters can also be placed on the drawing using the Text Options.

Support |
Displays the support type |
Bottom Element Trim (Object Info palette only) |
Displays the vertical trim of the bottom unit; click Populate Array if not displayed |
Listening Height |
Sets the listening height reference for the speakers’ dispersion lines. Listening height must be less than any speaker’s elevation (Z value). |
Override A/B/C dispersion (V) with array angles |
Calculates the dispersion based on the array’s Angle Relative to Preceding value for each speaker set on the Array tab, rather than the individual speaker’s vertical dispersion angles |
Show dispersion for range 1/2/3 |
Draws the top, bottom, left, and right dispersion lines for each of the three dispersion ranges selected for display, for each speaker (or the Overall range if expanded dispersion is not selected). When applicable, a center reference line is drawn for each of the three dispersion ranges, for each of the speaker models in the array. An outline or hatch pattern representing the listening area coverage “shadow” is drawn when the throw distance and the vertical dispersion and tilt angles allow the speaker to cover the area at or below the Listening Height.
|
Show dispersion hatch |
Displays hatch fills in the coverage shadow of each enabled dispersion range |
Show rigging guides |
Displays the guides which indicate the approximate location of the motors on the bumper |
Hanging Support |
Before attaching hoists to the bumper, select whether to hang the array by one, two, or multiple hoists. For one hoist, the hanging point of the load is generated in the center of the speaker array. For two hoists, a rigid beam is generated in the vertical middle of the bumper, and all support objects connect to this beam. Snap points indicate where the two hoists can be attached. For multiple hoists, the entire bumper is a rigid structure, and all support objects can be connected to this structure. Snap points indicate where a minimum of three hoists can be attached. |
Populate Array (Object Info palette only) |
The first time the speaker array is created, click Populate Array after exiting the Array Detail and Configuration dialog box, to add the bumpers and speakers to the array |
Text Options |
Opens the Text Options dialog box, to enable the display and format the text of labels; see Formatting speaker object labels |
Default Text Position (Object Info palette only) |
Restores text labels to their default positions |
Opens the Classes dialog box, to specify class naming for the various portions of the speaker array. This allows portions of the cabinets, grills, and other elements to be set to visible, grayed, or invisible. Different textures can be applied to the different part classes, for a highly realistic appearance. Use the standard class, select a class from the list of classes present in the drawing, or create a new class. Select <Speaker Array Class> to place the speaker element in the same class as the speaker array. Class Prefix: Specifies an optional default root class naming standard for all speaker array parts; click Assign Default Classes With Prefix to begin all speaker array class names with the prefix, so that they are sorted together. Assign Default Classes With Prefix: Sets the class names for all speaker array elements to the standard, using the Class Prefix if there is one. Speaker array elements: For each portion of the speaker array, specifies the class name standard; the class names shown here are applied to the elements. |
|
Update (Object Info palette only) |
Updates the object when changes have been made to the Object Info palette parameters. Speaker and bumper alignment is adjusted if necessary, and the dispersion ranges and hatch are refreshed. |
Load Information |
A speaker array is considered a point load in Braceworks calculations; if the insertion point is on a rigging object, it is considered to be a load on that structure. Load information is used for Braceworks calculations and reports (Braceworks required). |
