Creating arrays

You can create and define characteristics of new arrays with the Array Builder. To launch the Array Builder, click on the icon at the top left of the screen.

Using the Array Builder

You can create and define characteristics of new arrays with the Array Builder . To launch the Array Builder, click on the icon at the top left of the screen.

Launch Array Builder

Add X1, S21 or X2 modules

To choose which type of module you would like to add, use the Product Line menu in the array builder. Arrays can only be created with either X1 , S21 or X2 , and module types cannot be combined within the same array.

Creating S21 array using the array builder

Configuring an array

When creating a new array, start by selecting a template in the Array Builder. For X1 and X2, there is one standard Matrix Array template. For S21, multiple array configurations are available, allowing you to choose the layout that best fits your subwoofer arrangement. Once a template is selected, template-specific controls will appear in the properties panel on the right, adjusting dynamically based on the selected template.

Name your array at the top of the properties panel. The name can be changed later by editing it directly in this panel.

Configuring X1 Arrays

• Adjust the number of rows and columns in the properties panel to modify the array’s size and shape.

• Change the module type by clicking on the array in the viewport and using the Select Module Type dropdown. For X1 arrays, MD96 and MD80-S modules can be used together within the same array.

• X1 module types:

  • Light Blue cells are MD96 modules.
  • Dark Blue cells are MD80-S modules.
  • Purple cells are S21 modules.

Configuring X2 Arrays

• MD30 modules are available for X2 arrays.

• Module positions can be adjusted using the coordinate spin boxes.

• X2 module type:

  • Yellow cells are X2 MD30 modules.

Configuring S21 Arrays

S21 arrays offer multiple template options:

• Matrix Array

• Ground Single-Depth Array

• Flown Single-Depth Array

• Ground Multi-Depth Array

• Flown Multi-Depth Array

Regardless of the template selected, all modules within the template function together as a single array, even if multiple clusters are separated by distance.

Template-Specific Properties

Depending on the selected template, different properties will appear in the properties panel:

• Ground Effect: When enabled, this toggle ensures that beams optimized from the array account for the acoustic effect of the ground. The floor height is assumed to be at the bottom of the array. Enable this option when arrays are placed on the floor to ensure accurate optimization.

• Select Modules and Change Orientation: Click on individual modules in the viewport and use the dropdown to reverse their orientation.

• Layout:

  • Clusters: Clusters (also sometimes referred to as stacks) are groups of modules that are either flown or ground-stacked.

  • Define the number of clusters, the number of modules per cluster, and the number of cluster rows.

  • Spacing Parameters:

    • Equally Spaced Along: Determines the even distribution of clusters along a defined axis.

    • Spacing Between: Specifies the gap between clusters.

    • Distance Between Centers: Defines the distance between the central points of each cluster.

Once the array is configured, click Done to place the array at the origin point (0,0,0).

Adding Rigging Spacing

In HOLOPLOT Plan, the rigging configuration of your arrays can affect the accuracy of your simulation. Understanding when and how to use rigging spacing is essential for reflecting the real-world behavior of your setup.

X1 Arrays: Rigging Spacing Toggle

By default, X1 arrays are designed to be rigged, which is indicated by the Rigging Spacing toggle in the software. When this toggle is activated, it adds 36mm width & 3mm height spacing between the individual modules. This adjustment ensures that the simulation accurately reflects the behavior of a rigged array.

• When to Use the Rigging Spacing Toggle: If your design includes rigged X1 arrays, keep the toggle active for accurate simulation results.

• Ground Stacking or Custom Rigging: If you plan to ground stack your X1 array or use a custom rigging solution, deactivate the Rigging Spacing toggle. This ensures that the array configuration matches your intended setup.

X2 Arrays: No Rigging Spacing Needed

X2 arrays have built-in rigging, so there’s no need to manually adjust rigging spacing or worry about the toggle when working with X2 arrays. The software automatically accounts for the necessary spacing in your design.

S21 Arrays: Rigging Spacing Toggle

Like X1, S21 arrays also feature a Rigging Spacing toggle. When activated, it adds 36mm width & 3mm height spacing between individual modules, ensuring an accurate simulation of the rigged configuration.

Editing arrays

To edit an array once it's been created, simply head to the array and click 'edit array' in the bottom of the Properties Panel. If beams are optimized for the array, they'll need to be unoptimized before the array is editable.
