JBL CBT 50LA-LS 50CM TALL COLUMN SPEAKER EN54

Product Overview

The JBL CBT 50LA-LS is an EN 54-24 certified passive line array column loudspeaker for voice-alarm and life-safety installations that also require quality program audio. Eight 50 mm drivers with JBL Constant Beamwidth Technology provide consistent vertical coverage and reduced out-of-coverage lobing in reverberant spaces. Switchable music/speech voicing and built-in 70V/100V transformers support both emergency communication and everyday distributed audio. Finished in black, it suits houses of worship, auditoriums, government spaces, and transport facilities.

Product Description

The CBT 50LA-LS shares the Constant Beamwidth Technology platform of the standard 50LA-1 and adds EN 54-24 compliance for life-safety applications when installed with the included MTC-PC2 panel cover. Analog delay beam-forming and amplitude tapering deliver even vertical coverage from a slim column, while switchable voicing tailors response for music or speech. Built-in 70V/100V transformers plus 8-ohm direct operation allow integration into constant-voltage paging and voice-alarm systems or low-impedance amplifier channels. Dynamic SonicGuard overload protection helps preserve the loudspeaker under sustained output. A swivel (pan)/tilt wall bracket is included for accurate aiming.
