JBL, CBT 200LA-1, Line Array Column Speaker with Thirty-Two 50 mm (2 in) Drivers
Features:
- Patented Constant Beamwidth Technology™ provides true wide-band constant directivity coverage up to the highest frequencies and reduces out-of-coverage lobing.
- 200 cm (6.6 ft) height extends pattern control to include lower frequencies.
- Vertical pattern coverage switchable between 30° and 15° for medium or long-throw coverage.
- Asymmetrical Progressive-Gradient vertical coverage setting directs more sound toward the far area of the listening space, making front to back sound levels more consistent. Progressive-Gradient extent is adjustable.
- Narrow width of 98.5 mm (3.8 in) fits visually into a wide variety of applications.
- Dynamic Sonic-Guard™ low-audibility overload protection.
- Swivel (pan)/tilt wall bracket included
- Built-in 70V/100V transformers, plus direct capability.
The CBT 200LA-1, with Constant Beamwidth Technology™, represents a breakthrough in pattern control consistency and coverage options, utilizing complex analog delay beam-forming and amplitude tapering to accomplish superior, consistent coverage without the inconsistent vertical beaming, uneven coverage, and out-of-coverage lobing that are typical of both powered and nonpowered column speakers.
The CBT 200LA-1 assembly consists of a top and a bottom loudspeaker module that, when bolted together end-to-end during installation, form a 32-driver array that is 200 cm (6.6 feet) tall. The height provides excellent pattern control over a wide bandwidth and superb throw capability. The combination of sound quality, pattern control, and compact design makes CBT 200LA-1 ideal for a wide variety of venues, including highly reverberant facilities and those requiring especially long throw or pattern control down to very low frequencies. Venue types include transit centers, conference centers, cathedrals, multipurpose spaces, gymnasiums, and theme parks, among many others.
The slim, compact design fits well into virtually any architectural decor.
Innovative Coverage Adjustment Capability - Symmetrical Coverage or Asymmetrical Progressive-Gradient Coverage
The CBT 200LA-1 allows the vertical coverage to be switched independently for each of the loudspeaker modules (top and bottom). This allows the system to be set for symmetrically narrow (15 degree) coverage, symmetrical broad (30 degree) coverage, or for asymmetrical progressive-gradient coverage (narrow top module and broad bottom module), which directs higher sound levels toward the far areas of the listening area, leveling out the SPL level differences from front-to-back within the listening space. The proportion of front-to-back differential can also be adjusted by externally lowering the drive level to the bottom loudspeaker module or setting to a lower tap when in 70V/100V operation. This innovative coverage adjustment capability allows a single loudspeaker model to more precisely match the coverage requirements in an extremely wide variety of project types and to accomplish a consistency of coverage that few other loudspeakers can achieve. Horizontal coverage is very wide, at 150° in the mid-range.
Adjustable Voicing
The voicing can be set to match the needs of the application through a Music/Speech switch. 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 distance. The Speech setting also increases mid-range sensitivity and mid-range Max. SPL capability.
Components
The thirty-two 50 mm (2 in) drivers each include dual neodymium magnets for light weight, wide bandwidth, high output levels and tighter driver-to-driver spacings, which helps to extend pattern control consistency up to the highest frequencies. Copper capped pole pieces lower both the driver inductance and the flux modulation, resulting in increased high frequency extension and reduced distortion at high drive levels. Butyl rubber surrounds provide long life even in high humidity environments. The drivers cones are weather treated and magnets are shielded. Minimally audible Dynamic SonicGuard™ 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 short-term overpowering.
Coupler Plate and Wall Brackets
The included Coupler Plate contains four M6 threaded points for attaching the included swivel (pan) / tilt wall-mount bracket, plus the back panel of the system includes twenty-eight (28) M6 inserts on the back panel which can be utilized to suspend the speaker using forged shoulder steel eyebolts, providing installation versatility.
High Outdoor Capability
CBT 200LA-1 can be installed either indoors or outdoors. The drivers are weathertreated, the fiberglass reinforced ABS cabinet is excellent for outdoor applications, external screws are stainless steel, terminals are outdoor-capable.
Wiring Hookup
It is important to make sure that the two speaker modules (top and bottom) are connected in the same polarity. Connecting the same signal cable in parallel to both speaker modules is recommended.
System Design Tools
Vertical coverage can be easily modeled using JBL's free CBT Calculator software, downloadable from the www.JBLPro.com website. EASE and CLF files for CBT 200LA-1 are posted on-line for modeling coverage using EASE and other modeling programs.
