Description
The DSA250i is a unique, column-type loudspeaker for full-range
FGM (foreground music) and voice applications. It also functions
with additional DSA Series loudspeakers to provide increased
performance. For example, a DSA250i used with the DSA230
extends directivity to and increases the output at lower frequencies.
The DSA250i has the remarkable versatility of a user-adjustable,
vertical beamwidth. This is made possible because each transducer
has its own DSP (digital signal processing) and power amplifier.
Built-in networking provides for remote PC operation and control.
Intended to be flat-mounted to a wall, the user directs the DSA250i's
output from this position to the desired coverage area using the
supplied DSAPilot software. Pattern asymmetry provides similar
sound levels to both near and far listeners. Each of the two inputs
has user-adjustable EQ, delay, and compression.
DSA loudspeakers are engineered as a solution for applications
with difficult acoustics, physical mounting limitations, precise
vertical coverage requirements, and difficult aesthetic
requirements. They can replace typical horn/woofer or column-type
loudspeakers in small to medium venues. These include houses of
worship, auditoriums, theaters, concert halls, conference rooms,
transportation centers, athletic facilities, classrooms, museums,
shopping malls, and theme parks. The enclosure profile and
appearance reduces architectural impact.
Warranty: five years loudspeaker components; two years electronics.
