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.
