Figure 14: JBL VLA Calculator The JBL VLA calculator allows the designer to enter a seating section of the venue and input a JBL VLA SERIES array consisting of any combination of elements. The direct sound pressure level for the seating plane is plotted for up to 3 frequency bands concurrently. The calculator can also take into account air absorption. Also, the predicted frequency response can be plotted for any position on a seating plane. Alternatively, the JBL VLA SERIES arrays may be modeled within EASE 4.1 to 4.3 using the available DLL plug-in. With this technique, a more descriptive 3-D model may be created and analyzed. Multiple arrays of up to 14 elements can be flown into the model. 16

The JBL VLA calculator allows the designer to enter a seating section of the venue and input a
JBL VLA SERIES array consisting of any combination of elements. The direct sound pressure
level for the seating plane is plotted for up to 3 frequency bands concurrently.
The calculator
can also take into account air absorption. Also, the predicted frequency response can be
plotted for any position on a seating plane.
Alternatively, the JBL VLA SERIES arrays may be modeled within EASE 4.1 to 4.3 using the
available DLL plug-in. With this technique, a more descriptive 3-D model may be created and
analyzed. Multiple arrays of up to 14 elements can be flown into the model.
