JBL DDA (Digital Directivity Analysis) Software
Summary:
-
In JBL DDA (Digital Directivity Analysis) software, selecting a point source loudspeaker that features a physical rotatable horn (such as the JBL AM7212-00) does not provide a direct setting to rotate the internal horn measurement file or orient the cabinet horizontally
. Because CLF (Common Loudspeaker Format) files reflect fixed measurement configurations, users can accurately model horizontal coverage for the rotatable waveguide frequencies by setting the loudspeaker's Roll [°] angle parameter to 90.00 .
Troubleshooting:
- End-User Action:
-
Open the project design in JBL DDA software
.
-
Select the Point Source Loudspeaker (e.g., JBL AM7212-00) in the Loudspeakers table
.
-
In the positioning grid, locate the Roll [°] column for the target loudspeaker
.
-
Change the Roll [°] value from
0.00to90.00 .
-
Verification: Review the calculated acoustic coverage map in DDA to observe the modified high-frequency dispersion pattern reflecting the rotated waveguide orientation
