JBL CBT 50LA-LS-WH overview

  • 1Description

The white Constant Beamwidth Technology CBT 50LA-LS Line Array Column Loudspeaker from JBL utilizes analog delay beam forming and amplitude tapering to accomplish consistent vertical coverage without the narrow vertical beaming and out-of-coverage lobing that are typical of straight form-factor passive column speakers.

The slim, compact design fits well into virtually any architectural decor. The combination of excellent sound quality and pattern control, and compact (20.8" tall x 3.9" wide) design makes the CBT 50LA-LS Line Array Column Loudspeaker suitable for a wide variety of applications, such as retail stores, concourses, transit spaces, fill applications, conference rooms, architectural spaces, audio for video, lecture halls, and other applications where such a combination is desired.

The voicing can be set to match the application through the Music/Speech switch, conveniently located on the side of the cabinet. The Music setting provides flat frequency response, while the Speech setting produces a mid-range presence boost to provide clear, intelligible speech even at the longest throw distances.

The shielded drivers feature dual neodymium magnets for light weight. Copper-capped pole pieces lower the driver inductance and flux modulation. This increases high frequency extension and reduces distortion at high drive levels. Butyl rubber surrounds provide long life even in high humidity environments.

Dynamic SonicGuard overload protection minimizes distortion at high drive levels by limiting low frequency excursion dynamically. This maximizes clarity at high drive levels while protecting the drivers from damage due to overpowering.

A swivel (pan) / tilt wall-mount bracket is included, and ten M6 inserts on the back panel accommodate third-party mounting brackets, or can be utilized to suspend the speaker using M6 forged shoulder steel eye bolts, providing versatility of installation. The loudspeaker can be installed either indoors or outdoors. The drivers are weather treated, and the fiberglass reinforced ABS cabinet with UV resistant paint is suitable for outdoor applications. The external stainless steel screws and the painted aluminum grille resist rusting in harsh conditions.
