The CBT 50LA-LS is a line array column loudspeaker featuring eight 50 mm (2-inch) drivers. It employs Constant Beamwidth Technology (CBT), which uses analog delay beamforming and amplitude tapering to achieve consistent vertical coverage while minimizing narrow vertical beaming and out-of-coverage lobing commonly associated with traditional passive column speakers. The product is certified to the EN 54-24 standard for loudspeakers used in life safety systems.

• Constant Beamwidth Technology provides constant directivity and reduces lobing
• EN 54-24 Compliant for Life Safety Applications
• Switchable voicing with flat response for music mode and presence peak for speech mode
• Dynamic SonicGuard overload protection
• Built-in 70V/100V transformer and 8 ohm direct capability
• Swivel and tilt wall bracket included
