200 cm Tall Constant Beamwidth Technology™ Line Array Column Speaker with Thirty-Two 50 mm (2 in) Drivers

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.



·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 in) 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.




Thirty-two 50 mm (2 in) Full-Range Drivers

Frequency Range (-10 dB)

80 Hz – 20 kHz

Frequency Response (±3 dB)

130 Hz – 18 kHz (narrow coverage, music mode setting)

Coverage - Vertical

Narrow Mode: 15° (500 Hz – 16 kHz, +15°/-2° [<60° down to 220 Hz, <90° down to 140 Hz])

Broad Mode: 30° (400 Hz – 12 kHz, +15°/-8°, [<60° down to 220 Hz, < 90° down to 140 Hz])

Asymmetrical Progressive-Gradient Mode: (Top speaker module set at “Narrow” and bottom speaker module at

“Broad”, for “J-type” coverage, sending higher sound levels toward the far area of the listening space): 22.°(+7°

from aiming axis up; -15° from aiming axis down, 300 Hz – 12 kHz, +15°/-8°, [<60° down to 220 Hz, <90° down

to 140 Hz])

Coverage - Horizontal

150° (ave, 1 kHz – 4 kHz, ±20°)

Sensitivity - Narrow

(speech mode): 95 dB (2 kHz – 5 kHz)

(music mode): 92 dB (150 Hz – 18 kHz)

(music mode): 90 dB (150 Hz– 18 kHz)

Sensitivity - Asymmetrical Progressive

Gradient Mode (on-axis)

(speech mode): 94 dB (2 kHz – 5 kHz)

(music mode): 91 dB (150 Hz – 18 kHz)

Nominal Impedance (direct)

8Ω per half (top and bottom) for 4 ohms total (in thru mode).

Min-Z for system = 2.9Ω.


Ensure identical polarity of hookup – for proper functioning, the two loudspeaker modules (top and bottom) must

be hooked up in same polarity. Parallel hookup at the two sets of back panel input terminals is recommended.
