On-Axis Profiles

Profile Mode

The purpose of the On-Axis Profile function is to draw a uniform plane to the speaker’s axis, starting from the speaker’s rigging point and ending at the farthest point of the audience area. Several of these can be drawn, and the idea is to create a separate On-Axis Profile for each speaker group (for example: Main, Side, 270). The primary purpose is to produce as accurate model as possible of the profile of the venue along the axis of the speaker. To be clear, we are only modeling what happens on the axis of the speakers, and not creating a complete 3D model of the venue. This is an advanced workflow designed for the most demanding conditions and requires its user to understand the three-dimensional challenges of speaker system coverage.

Measure Profile

Step 1 – Set the position of the instrument

Set the instrument Height.
Depth Offset can be used to allow measurements 
behind or in front of the actual starting point of the plane. 
Height Offset does the same in vertical axis.

Step 2 – Measure and enter values

Stand at the front rigging point of the speaker and start measuring the on-axis profile of the venue in direction the speaker is pointing.
Start at the closest point and measure in order from front to back. Amount of target points can be modified (-/+).
If all target points are set to ”0”, app won’t create a profile.

Adjust Parameters

Step 3 – Modify the basic parameters if needed

Set the Width for the profile.
Listener Height can be set. (Not all formats support this)
When Back Wall Height is set, additional plane is created after last measured target. This function can be turned off by setting the value to zero.

Step 4 – Define the profile starting point relative to the zero point (origin) of the simulation program

Visual Guide shows a graphic representation of the profile’s relation to the origin.
Set Depth and Width parameters to define the position.
Horizontal Aiming sets how many degrees plane is rotated horizontally.
L-R Mirror function will automatically make copy of the plane to the opposite site.
Note

Back Wall can be used as ”ArrayProcessing Wall” or for overshooting purposes with autosplay feature.

Create On-Axis Profiles From Design File

The On-Axis application is able to read the speaker group names and positions from the supported design file which can be used to create the On-Axis Profiles. When the position data is imported, profiles are drawn directly to the correct location in the simulation program.

Step 1 – Select Source File

When the operation mode of the app is set to profiles, an import button appears in the upper corner with which you can import the design file. Check the supported file formats from the compatibility chart. 

Step 2 – Map

Map which source is assigned to which profile.

Step 3 – Select Main Speaker Group

Choose your ”Main” stereo system from the dialog box. One wide profile is drawn for the selected system.

Step 4 – Create On-Axis Profiles

Create profiles from data.

Result

On-Axis Profiles are created from the data.
Profile starting point positions are updated from data.
