The JBL's CBT100LA-LS line array column loudspeaker uses Constant Beamwidth Technology (CBT) to deliver exceptional pattern control in a variety of indoor and outdoor applications. This public address system employs 16 2" full-range drivers that use CBT, a complicated analogue delay beam-forming, and amplitude tapering to achieve continuous vertical coverage without the limited vertical beaming and out-of-coverage lobing that are common with straight form-factor column speakers. This EN54:24 approved loudspeaker includes a built-in 70/100V transformer as well as direct capability at 8 ohms.
The sleek, compact 39.4" tall line array blends well with any architectural style while providing consistent pattern control across the intelligibility range. The vertical beamwidth can be adjusted from 40 degrees for medium-throw coverage to 15 degrees for long-throw applications. The Music/Speech switch can also be used to adjust the voice to match the application. The Music setting has a flat frequency response, whereas the Speech mode has a midrange presence increase for clear, comprehensible speech even at long distances.
