JBL CBT 50LA-1-WH Line Array Passive Column Loudspeaker Eight 50 MM Wall Mount Constant Beamwidth Technology? Line Array Column Loudspeaker with Eight 50 mm (2 in) Drivers. With improved mounting bracket for enhanced aiming flexibility. The CBT 50LA-1, with Constant Beamwidth Technology?, represents a breakthrough in pattern control, utilizing analog delay beam-forming and amplitude tapering to accomplish consistent vertical coverage without the narrow vertical beaming and out-of-coverage lobing that are typical of straight form-factor passive column speakers. The slim, compact design fits well into virtually any architectural decor. The combination of superb sound quality, excellent pattern control, and compact (53 cm [20.8 in] tall by 10 cm [3.9 in] wide) design makes CBT 50LA-1 ideal for a wide variety of applications, such as retail stores, concourses, transit spaces, fill applications, conference rooms, architectural spaces, audio for video, lecture halls, and other applications where such a combination is desired. The voicing can be set to match the application through the Music/Speech switch, conveniently located on the side of the cabinet. The Music setting provides flat frequency response, while the Speech setting produces a mid-range presence boost to provide clear, intelligible speech even at the longest throw distances. Features: Patent-pending Constant Beamwidth Technology? provides constant directivity up to the highest frequencies and reduces out-of-coverage lobing. Switchable voicing provides flat response in music mode or mid-range presence peak in speech mode. Dynamic SonicGuard? overload protection Built-in 70V/100V transformer, plus 8 ohm direct capability.
