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) available M6 inserts on the back panel which can be

utilized to suspend the speaker using forged shoulder steel eyebolts, providing

installation versatility. Alternatively, for ﬂush-mounting the back of the cabinet to a

surface, two optional MTC-CBT-FM1 brackets can be utilized (one on the top and one

on the bottom loudspeaker module).

High Outdoor Capability

CBT 200LA-1 can be installed either indoors or outdoors. The drivers are weather-

treated, the ﬁberglass reinforced ABS cabinet is excellent for outdoor applications,

external screws are stainless steel, terminals are outdoor-capable, optional MTC-PC2

terminal panel cover can provide additional terminal protection, the painted aluminum

grille resists rusting, and the grille backing breaks up driving rain. With MTC-PC2, the

speaker is rated IP-55 per IEC529.

CBT 200LA-1

200 cm Tall Constant Beamwidth

Technology™ Line Array Column Speaker

with Thirty-Two 50 mm (2 in) Drivers

Key Features:

䉴

Patented Constant Beamwidth

Technology™ provides true wide-band

constant directivity coverage up to the

highest frequencies and reduces out-of-

coverage lobing.

䉴

200 cm (6.6 in) height extends pattern

control to include lower frequencies.

䉴

Vertical pattern coverage switchable

between 30° and 15° for medium or

long-throw coverage.

䉴

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.

䉴

Narrow width of 98.5 mm (3.8 in) ﬁts

visually into a wide variety of

applications.

䉴

Dynamic Sonic-Guard™ low-audibility

overload protection.

䉴

Swivel (pan) / tilt wall bracket included

䉴

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 non-

powered 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.

CBT 200LA-1 Line Array Column with Thirty-Two 50 mm (2 in) Drivers

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.

CBT 200LA-1 is available in black or white (-WH).
