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:
1. Click the Speaker Array tool from the Spotlight tool set.
2. Click once in the drawing to set the object’s position. Click again to set the object’s rotation.
3. If this is the first time a speaker array is placed on the drawing, the object properties dialog box opens. Specify the default preferences, which apply to all arrays placed subsequently in this drawing. Properties can be edited later in the Object Info palette. Click OK.
4. A bumper is inserted on the drawing. From the Object Info palette, click Configure Array.
The Array Detail and Configuration dialog box opens. Specify the bumper parameters on the Bumper tab.
Click to show/hide the parameters.

6. Set up the array configuration on the Array tab.
Click to show/hide the parameters.
Parameter |
Description |
Array Support |
Specify how the speaker array is supported: Flown-Motors, Flown-Crank Lift, Ground-Stacked, or Tripod. Flown arrays place the speakers below the bumper. Ground-stacked arrays are inserted above the bumper. Arrays supported by a tripod do not include a bumper. |
Bumper Type |
Displays the bumper type that was selected on the Bumper tab (does not apply to tripod-supported arrays) |
Bumper Angle |
Sets the angle of the bumper, establishing a starting angle for the top mounting (does not apply to tripod-supported arrays) |
First Speaker Shift |
Controls the offset of the speaker stack from the bumper. Enter a positive value to shift the speaker stack towards the rear of the bumper; enter a negative value to offset the speaker stack towards the front of the bumper. |
Tripod Height |
For tripod-supported arrays, specifies the height at the top of the tripod |
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 Speaker Types to Add list, and then clicking Add/Swap 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. |
Speaker Types to Add |
Lists the speaker(s) defined on the Speaker tabs. These speakers are available for placement in the array. |
Add/Swap Speaker(s) |
Adds one or more selected speakers to the array; to swap speakers, select the speaker(s) to be replaced in the Definition list first. To add speakers without swapping, ensure that no speakers are highlighted in the Definition list. |
Type Counts |
Lists the number of each type of speaker, as well as the total number of speakers, included in the array |
Delete Speaker(s) |
Deletes the speaker(s) selected in the Definition list |
Angle Relative to Preceding |
Sets the angle of the speaker(s) selected in the Definition list. Individual speakers have range dispersion angle settings, but these can be overridden to use this angle set for the array instead. The Rel° and Act° angles in the Definition list update to reflect the current speaker angles. |
Preview |
Displays a preview of the speaker array, which updates as parameters change; the arrows indicate the front face |

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 |
Class Speaker Array Parts |
When first selected, automatically creates classes for the different parts of the speaker, for appearance and visibility control. 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 (Renderworks required), for a highly realistic appearance. Once the classes have been created, this check box toggles whether class visibility changes apply to the selected speaker object. You may need to click Update to view any changes. |
Parts Classes Prefix |
When speaker parts are classed, enter a prefix for the class names so that they are sorted together |
