Description
The DSA 230i is a unique, column-type loudspeaker for voice-only
and voice/BGM (background music) applications. It also functions
with additional DSA Series loudspeakers to provide increased
performance. For example, used with a DSA250i, the DSA230i
extends directivity to and increases the output at lower frequencies.
The DSA230i 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 DSA230i’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 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.
