1. Product Description

The phased-array sound column is a new type of public address system. By applying the electronic and
digital signal processing (DSP) technologies, it can simulate the directivity from different shapes of
sound columns, while the inherent performances of the sound column will not be affected, e.g. rated
power, range of effective frequency response and max. sound pressure level.

With DSP technologies, we may operate from the remote controller to change the directivity of speaker
system at some extent. This is suitable for loud speaking in a hall where the building acoustics is poor
(especially long reverberation time). This product is most suitable for the hardware (sound box, DSP
processor) of the loudspeaker system in sports venues (where the volume is large, the building
acoustics is poor, the reverberation time is long and the sound is muddy), so that it can be combined with
special software to make the controllable sound cover useful area (auditoria, etc) correctly and prevent it
from diffusion to useless area (e.g. ceiling, door or window). In this case, it can reduce the investment in
acoustic decorations in venues and decrease the energy loss caused by loudspeaker system. This leads
to reduced investment in both the acoustic decorations and sound system in the sports venue.

2. Functions

 Acoustically simulate the sound columns of different shapes, e.g. inclined, concave, convex and

more complicates shapes.

 Active sound column with inbuilt digital signal processor and digital power amplifier, so that it is

no need for external power amplifier.

 Compatible with line signal input (300mV), line signal output (200mV) and broadcasting power

signal input with fixed voltage (70V or 100V).

 Volume, tone and other parameters of the sound column adjustable.
 The LED array screen on the right lower of the sound column can display different parameters

and messages.

 Operate from infrared remote controller.
 Compact size, easy installation and high electroacoustic sensitivity.
