Line array units exhibit narrow dispersion on the

coupling plane and wide coverage on the non-coupling
plane. These coverage characteristics, needed to perform
in multi-unit arrays, drastically reduce their ability to be
used as individual units. In order to overcome this
obstacle and convert the narrow coverage needed for an
array, to the wider coverage needed to use the

convert

15A as an individual unit, D.A.S. engineers developed the

Digitally Convertible Dispersion (DCD ), a proprietary signal
management interface which employs complex signal

processing via an advanced DSP. By means of the

DCD ,

the dispersion on the coupling plane of the

convert 15A

can be switched from 20º to 40º. Configuring the
coverage characteristics of the

convert 15A is surprisingly

simple. Switching the dispersion from 20º to 40º is as
easy as selecting one of the digital presets directly from
the

interface on the rear of the cabinet or remotely

via

Powering the

convert 15A is a package of integrated

electronics that includes the

DCD interface, the digital

signal processing engine and a new 2,000 W (4,000
Wpeak) amplifier. The three channel, high efficiency Class
D design is equipped with a switch mode power supply
(SMPS) and a comprehensive protection package for both
the amplifier as well as the components. One channel
powers the low frequency way, and the other two
channels power the high frequency drivers.

The

DCD incorporates the latest in digital signal

processors. Brickwall FIR filters have been used to
provide perfect alignment between ways achieving
exceptionally uniform coverage all the way down to the
crossover point. The top-of-the-line AD/DA converters
employed allow for significant improvements in dynamics,
lower distortion and ultra-low noise levels.

The new

convert 15A serie arrayable loudspeaker is a powered, multi-purpose system incorporating a

series of breakthrough features that offer an unmatched level of versatility and performance. As its name
implies, the system's coverage capabilities can be easily “converted” to meet the specific requirements of
almost any application. An innovative electronics and digital signal processing package combined with
ground-breaking horn design offers “user-definable” optimization of the system's dispersion characteristics.
This allows the

convert 15A to be deployed in either horizontal or vertical curved source arrays, or used

individually as a point source.

Add to these unique features, a powerful 2000 W, 3 channel, Class D amplifier, connectivity for system

management and control, and optional rigging hardware for safe flying or ground-stacking, and you have a
loudspeaker system engineered for exceptional flexibility and outstanding performance.
