CBT 50LA-1 - JBL Professional

1 CBT 50LA-1 Constant Beamwidth Technology . Line Array Column loudspeaker with Eight 50 mm (2 in) Drivers Key Features: Patent-pending Constant Beamwidth Technology provides constant directivity up to the highest frequencies and reduces out-of-coverage lobing. Switchable voicing provides at 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. Swivel (pan) / tilt wall bracket included. Overview: The CBT 50LA-1 , with Constant Beamwidth Technology , represents a breakthrough in A swivel (pan) / tilt wall-mount bracket is included and ten M6 inserts on the back pattern control, utilizing analog delay beam- panel t the spacing of common mounting brackets, or can be utilized to suspend the forming and amplitude tapering to speaker using M6 forged shoulder steel eyebolts, providing versatility of installation.

2 Accomplish consistent vertical coverage CBT 50LA-1 can be installed either indoors or outdoors. The drivers are weather- without the narrow vertical beaming and treated, the berglass reinforced ABS cabinet with UV resistant paint is excellent for out-of-coverage lobing that are typical of outdoor applications, external screws are stainless steel, and the painted aluminum grille straight form-factor passive column speakers. resists rusting in the harshest conditions. The slim, compact design ts well into Available in black or white (-WH). virtually any architectural decor. The combination of superb sound quality, excellent pattern control, and compact Speci cations: (53 cm [ in] tall by 10 cm [ in] wide) Components: Eight 50 mm (2 in) Full-Range design makes CBT 50LA-1 ideal for a wide Frequency Range (-10 dB)1: 80 Hz 20 kHz variety of applications, such as retail stores, Coverage Pattern: Vertical 20 ( kHz - 16 kHz, 10 ).

Insert Points: Ten M6 swivel (pan)/tilt insert points on back panel. The drivers feature dual neodymium Mounting: Included swivel (pan) / tilt wall bracket provides continuously variable magnets for light weight. Copper-capped pole +/-80 degree left-right swivel aiming (at no up/down tilt -- see Bracket Guide for maximum swivel range at various up/down tilt angles), pieces lower both the driver inductance and continuously adjustable 15 degree tilt, as well as 5 degree xed the ux modulation. This increases high- increment points within the range. Ten threaded mounting points frequency extension and reduces distortion located on back panel conform to industry standard rectangular 108 x at high drive levels.
