JBL IVX-587481/230 Intellivox Series DSX280HD 16 x 40 Watts RMS 12 x 4″ Full Range Beam Shaping Active Column Loudspeaker

JBL Intellivox DSX280 HD Active Column Loudspeaker

The JBL Intellivox DSX280 HD Active Column Loudspeaker is engineered to provide a constant sound pressure level over distances of up to 35 meters, with even greater range achievable in less demanding acoustic conditions. The system features twelve custom-designed 4-inch loudspeakers and four individually driven 1-inch horn-loaded dome tweeters, powered by a sixteen-channel class-D amplifier and sophisticated switched-mode power supply for reliable long-term operation.

The individually driven dome tweeters deliver unmatched high-frequency vertical beam control, improving horizontal coverage and enhancing the subjective sound quality for both speech and music. The DSX280 HD includes a comprehensive set of surveillance functions to meet stringent Voice Alarm (life safety) requirements. JBL’s WinControl software allows intuitive management of beam steering parameters, audio processing, pre-sets, and surveillance functions. Its compact array design ensures unobtrusive installation, even in architecturally sensitive environments, and the system’s low-frequency response can be extended using a JBL subwoofer.

Designed with vertical beam shaping via DDS Technology, wide horizontal dispersion, 32-bit floating point DSP, dual line inputs, volume control, up to 20-second delay, eight-band parametric EQ, and eight user-definable password-protected presets, the DSX280 HD ensures high-fidelity, intelligible sound. Additional features include automatic volume control via a built-in ambient mic, network readiness, upgradeable firmware, integral surveillance, and simulation compatibility with DDA, Catt-Acoustic, Odeon, and EASE4.3.

Ideal applications include transport hubs, places of worship, lecture halls, theatres, conference facilities, atriums, and museums. Optional accessories include external ambient noise and temperature sensors, additional input sections, a full range of mounting options, and color matching service.
