JBL Professional Introduces CBT 50LA-LS Column Loudspeaker With EN54-24 Certification

JBL Professional has introduced the new CBT 50LA-LS line array column loudspeaker that comes with full EN54-24 certification.

EN54-24 is the EU standard for loudspeakers intended for use in voice announce and fire alarm systems.

The CBT 50LA-LS is an addition to the CBT Series (Constant Beamwidth Technology) that has been developed exclusively for the European installation market. It’s a very compact 50 cm high column that utilizes a straight line of eight 2-inch drivers, and contains low-saturation transformers so that it can be used on 70-volt/100-volt distributed loudspeaker lines or as low-impedance loudspeakers.

JBL CBT Series column loudspeakers were the first loudspeakers to incorporate the company’s newly introduced and patented Constant Beamwidth Technology, using passive beam-forming components to deliver a narrow vertical beamwidth and constant directivity coverage from a passive column, resulting in high intelligibility in difficult acoustical venues and consistent frequency response at every listener location

In addition, the CBT loudspeakers incorporate Dynamic SonicGuard overload protection circuitry, which reduces distortion at high drive levels, along with user variable voicing which allows for selecting a flat frequency response or a midrange presence peak for especially clear speech intelligibility.
