JBL Intellivox DC280 – Digitally Steerable Wall-Mount Column Array for Speech Intelligibility

Product Overview

The JBL Intellivox DC280 is a self-powered digitally steerable wall-mount column loudspeaker designed for superior speech intelligibility in reverberant commercial installations. Featuring 16 custom 4-inch full-range drivers and an 8-channel Class-D amplifier, the DC280 delivers consistent SPL coverage up to 35 meters — making it suited for lecture halls, theatres, conference facilities, atriums, and houses of worship where acoustic reflections challenge conventional loudspeaker designs. Its stainless steel AISI 304 enclosure with epoxy coating is engineered for long-term durability in permanent fixed-install environments, and the slim architectural profile supports discreet wall-mount integration in aesthetically sensitive commercial spaces. DDS (Digital Directivity Synthesis) vertical beam shaping provides precise audience targeting via WinControl software without mechanical adjustment after installation.

Product Description

The DC280 uses a patented 16-driver arrangement that optimizes horizontal coverage while DDS technology steers the vertical beam to the audience plane, suppressing ceiling and floor reflections in highly reverberant spaces. The 8-channel Class-D amplifier, paired with a switched-mode power supply, provides long-term reliable operation at 92 dB continuous SPL at 30 meters. Onboard 32-bit floating-point DSP includes 8-band parametric EQ, 8 user-definable password-protected presets, and up to 20 seconds of delay for multi-column time alignment in distributed commercial AV systems. The DC280's stainless steel enclosure (AISI 304) with epoxy coating is designed for environments requiring long-term corrosion resistance in fixed installations. Standard and optional configurations support dual line inputs, ambient noise and temperature sensors, and multiple mounting accessories. WinControl software provides remote parameter management, beam steering adjustment, and system monitoring from a central interface.

Key Features

• Digitally Steerable Vertical Beam (DDS) — Software-controlled beam shaping targets the audience plane and minimizes reflections, maintaining speech intelligibility in reverberant lecture halls, theatres, and conference spaces.
• 16 × 4-inch Full-Range Drivers — Patented driver arrangement delivers consistent 35-meter SPL coverage with optimized horizontal dispersion.
• 8-Channel Class-D Amplification — Onboard amplifier eliminates external rack equipment, simplifying installation and reducing equipment room requirements.
• 32-Bit Floating-Point DSP — High-precision processing supports 8-band parametric EQ, delay up to 20 seconds, and 8 password-protected user presets.
• Stainless Steel AISI 304 Enclosure — Corrosion-resistant construction with epoxy coating provides long-term durability in permanent fixed-install environments.
• WinControl Software Integration — PC-based DSP management, beam steering configuration, and remote system monitoring.
• Up to 20 Seconds Onboard Delay — Supports multi-column time alignment in distributed commercial AV configurations without external delay hardware.
• Optional Accessories — Ambient noise/temperature sensors, multiple input configurations, and mounting accessories for varied installation requirements.

Typical Applications

• House of worship — mid-size sanctuaries requiring wall-mount beam-steered column coverage with consistent intelligibility up to 35 meters
• Auditorium — lecture halls and performing arts venues requiring precise vertical beam control to manage reflections and maintain intelligibility
• Conference room — conference facilities requiring slim architectural wall-mount column reinforcement with DSP flexibility
• Transportation terminal — airports and transit hubs requiring compact wall-mount column paging systems with extended delay for time alignment
• Training room — corporate and educational training facilities requiring consistent 35-meter beam-steered coverage
• Multi-purpose room — flexible-use commercial spaces needing remotely reconfigurable coverage zones from wall-mounted columns

Frequently Asked Questions

What is the difference between the DC280 and the DS280?

The DC280 is a wall-mount (DDC series) column with the same core driver and amplifier specification as the DS280. The DS280 additionally includes voice alarm and life safety system compatibility, automatic volume control (AVC), and surveillance features. Choose the DS280 for installations requiring EN54 voice alarm integration; choose the DC280 for standard commercial speech reinforcement applications.

Does the DC280 work with third-party control systems?

The DC280 uses WinControl software for DSP management. Third-party control integration compatibility should be confirmed with your AV system integrator. Contact Creation Networks for guidance on your project.

What is the warranty for the Intellivox DC280?

JBL Professional products carry a limited manufacturer warranty. Commercial installation warranty terms should be confirmed with an authorized distributor. Creation Networks provides warranty support for commercial AV projects.

Can multiple DC280 units be time-aligned in a distributed system?

Yes. The DC280 supports up to 20 seconds of onboard delay, enabling multi-column time alignment in distributed commercial AV systems without external delay hardware.
