|HARMAN’s JBL Professional Unveils CBT 200LA-1 Constant Directivity Column
LAS VEGAS, Nevada – At InfoComm 2012, HARMAN’s JBL Professional is introducing the CBT 200LA-1, the
newest and tallest model in the popular CBT Series of constant directivity column loudspeakers. At 200 cm (6.6
feet) tall, this array of 32 drivers (each measuring 50 mm/2 inches) provides consistent pattern control over a wider
bandwidth than is possible with shorter columns or fewer drivers. Vertical pattern coverage is adjustable to either
15 or 30 degrees to match the architectural characteristics of a wide variety of venues, and a variety of mounting
heights. In addition, an innovative asymmetrical progressive-gradient coverage mode can be selected, which makes the
speaker function similarly to the popular CBT 70J, directing more sound toward the far areas of the listening space to
help reduce variation in SPL levels from front to back throughout the area. This can make for a more pleasant and
intelligible listening experience, regardless of listener location.
“In addition to using patented CBT technology to provide constant directivity coverage so that listeners throughout the
space hear the same sound character everywhere, the 6-1/2 foot height of the CBT 200LA-1 allows this unobtrusive
column speaker to control down to a particularly low frequency for very clear sound, which is important when you want to
get well-controlled broadband coverage over a defined listening space,”
commented Rick Kamlet, Senior Marketing Manager, Commercial
Installed Sound, JBL Professional.
The narrow width (98 mm/3.8 inches) fits visually into a wide variety of
applications. Dynamic Sonic-Guard™ provides low audibility overload
protection. A swivel/tilt wall bracket is included, and MTC-FM flush-mount
wall brackets are available. The speakers can be operated at direct low
impedance or from a built-in 70V/100V transformer (240 Watts). A
speech voicing contour switch raises mid-range sensitivity and increases
maximum mid-range SPL by 4 dB, which can be especially useful for
speech-based applications. The CBT Series speakers are designed to be
installed either indoors or outdoors, and the IP-55 water rating allows the
speakers to be used for projecting distances outdoors.
The high degree of pattern control capability of the CBT 200LA-1 makes it
ideal for highly reverberant venues or for medium to long throw coverage
in a wide variety of applications including transit centers, cathedrals,
conference centers, multi-purpose spaces, mass paging applications,
gymnasiums, theme parks, and architectural spaces, among many others.
“The CBT 200LA-1 provides the pattern control you would typically get
from a constant directivity horn having a mouth that is two meters tall,”
Kamlet added, “except without the 15 to 20-foot depth that would be
needed for this degree of pattern control and with lower distortion, higher
output, control over coverage angle, full-range frequency response, and
an asymmetrical ‘progressive gradient’ coverage capability which
sends more sound toward the far areas of the space.”
