JBL’s CBT Calculator software is a precision engineering tool allowing audio professionals to design JBL’s CBT Constant Beamwidth Technology line array column loudspeakers into a wide variety of venues.
CBT Calculator shows the vertical coverage of CBT models in venues via a cross-sectional sound level coverage display. The program allows the use of up to 3 CBT speakers and virtual adjustment of their various adjustable settings for vertical coverage (narrow or broad) and voicing (speech or music/flat), in a space with up to 4 independent listening planes.
In addition to the SPL vertical coverage mapping of a proposed design, the CBT Calculator also shows the frequency response for up to 6 listener locations as well as an SPL summary of the listener locations over user-defined frequency bands. It helps designers to determine the best CBT model selection, the proper vertical coverage and voicing settings, mounting height and the down-angle, allowing audio professionals to design CBT column line array speakers into many venue-application types.
