Definition

Lists the speakers that make up the array and their relative and actual dispersion angles, in order from top to bottom starting from below the bumper. Add speakers to the list by selecting one or more from the Bumper and Speaker Types to Add list, and then clicking Add/Swap Bumper(s) or Speaker(s). To re-order the speakers, click the # column of the speaker to be moved, and drag it up or down the list. A horizontal line indicates where the speaker will be inserted in the current order.

Bumper and Speaker Types to Add

Lists the bumper and speaker(s) defined on the Bumper and Speaker tabs. The bumper and speakers in this list are available for placement in the array.

Add/Swap Bumper(s) or Speaker(s)

Adds one or more selected bumper or speakers to the array; to swap one or more units, select the unit or units to be replaced in the definition list first. To add speakers without swapping, ensure that no speakers are highlighted in the definition list.

Bumper and Speaker Counts

Lists the number of each type of bumper and speaker, as well as the total number of speakers, included in the array

Delete Bumper(s) or Speaker(s)

Deletes the bumpers or speakers selected in the definition list

Angle Relative to Preceding

Rack

Enter notes about the rack driving the speaker (this can only be accessed when accessing the speaker settings from the Object Info palette of a selected speaker array)

Drive Line

Indicates information about the drive line feeding signal to the speaker (this can only be accessed when accessing the speaker settings from the Object Info palette of a selected speaker array)

Preview

Displays a preview of the speaker array, which updates as parameters change; the arrows indicate the front face

Array Details

Column ID

Specifies a name for the bumper-speaker combination that makes up the array

Location

Indicates the array location (such as Downstage Right)

Purpose

Indicates the purpose of the array (such as Center Fill)

Override A/B/C Vert. Disp. 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 or dead hang objects to the bumper, select whether to hang the array by one, two, or multiple hoists.

●        For one hoist, the hang 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 connected.

●        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 connected.

Populate Array

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

Default Text Position

Restores text labels to their default positions

Classes

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 suggested 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 Use Standard Classes to begin all speaker array class names with the prefix, so that they are sorted together.

●        Use Standard Classes: Sets the class names for all speaker array elements to the default suggested standard names, 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

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

(Braceworks required)

Includes the speaker array in Braceworks calculations; deselect to exclude it from participating in structural calculations

Load Group Name

The load category is always Audio for speaker array objects

Load ID

Enter a unique ID for the load for informational use in reports

Load Name

Identifies the object in load calculations

Total Weight

Enter the total weight of the bumper
