JBL Intellivox DSX500 - 28 x 4-inch Powered Column Loudspeaker with 130-Degree Horizontal/Adjustable Vertical Coverage and Bottom Amplifier in White Finish

The JBL Professional Intellivox DSX500 is the flagship model of the slim-line Intellivox DSX range, delivering unparalleled audio performance for large, highly reverberant, and architecturally sensitive environments. Equipped with 28 custom-designed 4-inch full-range drivers and 8 horn-loaded 1-inch dome tweeters, this powered column loudspeaker ensures precise vertical beam control and expansive horizontal coverage of 130 degrees. Engineered for optimal sound clarity, it is capable of maintaining even sound pressure levels across distances up to 70 meters, making it ideal for large-scale venues such as auditoriums, houses of worship, and transportation hubs.

The DSX500's advanced DDS (Digital Directivity Synthesis) technology enables highly customizable vertical beam shaping, ensuring exceptional speech intelligibility even in challenging acoustic conditions. The 16-channel class-D amplifier and sophisticated switched-mode power supply deliver reliable and efficient performance, while the integrated 32-bit DSP provides extensive signal processing capabilities, including delay, parametric EQ, and automatic volume control. With eight user-definable presets, remote monitoring, and control via RS-485 and JBL's proprietary WinControl software, the DSX500 is designed for seamless integration and ease of use in complex installations.

Certified for voice alarm (VA) applications, the DSX500 incorporates advanced surveillance features and thermal protection for enhanced reliability in critical situations. Its slim and unobtrusive design, finished in white RAL 9010, ensures compatibility with a wide range of architectural aesthetics. The system's low-frequency extension can be further enhanced with JBL subwoofers, offering an expanded audio spectrum for both speech and music applications.
