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 at user-selectable frequencies. The program allows the use of either one or two 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.
ProKon - is an amazing engineering calculator with multiple conversion and calculation modules.
