JBL Professional has introduced its CBT Series of passive line-array columns, featuring the company’s patent-pending Constant Beamwidth Technology (CBT) circuitry that reportedly provides consistent constant-directivity coverage and audio clarity, even in difficult acoustical environments.
The coverage pattern of the CBT models can be adjusted—with a switch— between Broad Mode (designed for mid-throw situations) and Narrow Mode (for long-throw applications). This allows the CBTs to meet the requirements of a broad range of applications. In addition, the CBT speakers provide Dynamic SonicGuard overload protection circuitry, which reduces distortion at high drive levels, along with user variable voicing, which allows selecting a flat frequency response or a midrange presence peak for speech intelligibility.
