JBL CBT 100LA-1-Black ลำโพง Line Array Column Loudspeaker with Sixteen 50 mm (2 in) Drivers.

• Constant Beamwidth Technology™ Line Array Column Loudspeaker with Sixteen 50 mm (2 in) Drivers. With improved mounting bracket for enhanced aiming flexibility.
• The CBT 100LA-1, with Constant Beamwidth Technology™, represents a breakthrough in pattern control consistency, utilizing complex analog delay beam-forming and amplitude tapering to accomplish superior, consistent vertical coverage without the narrow vertical beaming and out-of-coverage lobing that are typical of straight form-factor column speakers.

FEATURES

• Patent-pending Constant Beamwidth Technology™ provides constant directivity up to the highest frequencies and reduces out-of-coverage lobing.
• Vertical pattern coverage switchable between 40° for medium-throw coverage and 15° for 
• long-throw applications.
• Switchable voicing provides flat response in music mode or mid-range presence peak in speech mode.
• Dynamic SonicGuard™ overload protection
• Swivel (pan)/tilt wall bracket included.
• Built-in 70V/100V transformer, plus 8 ohm direct capability.
