Description
The JBL CBT 50LA-1 is a compact passive line array column with eight 50 mm (2 in) full-range drivers. Constant Beamwidth Technology uses analog delay beamforming and amplitude tapering for consistent 20° vertical coverage without the narrow beaming and lobing of straight column speakers. This listing is for the black version.
A voicing switch chooses flat music response or a speech presence lift, and Dynamic SonicGuard protects against overload. The built-in transformer runs it on 70V or 100V lines, or at 8 ohms direct, and the improved swivel and tilt wall bracket is included.
Features
