JBL Professional has introduced its Constant Beamwidth Technology (CBT) Calculator 1.00 software. The CBT Calculator shows the vertical coverage of JBL CBT line-array column loudspeakers by means of an onscreen, cross-sectional sound level coverage display at user-selectable frequencies.

The CBT Calculator allows the use of either one or two JBL Professional CBT loudspeakers, while adjusting their various settings for vertical coverage (narrow or broad) and voicing (speech or music/flat) in a space with up to four independent listening planes. The software also shows frequency response for up to six listener locations as well as an SPL summary of each location over userdefined frequency bands.
