Atlas Sound ALX-4D-B 4-Speaker Column Array Speaker (Black)

Optimized Audio Coverage for Difficult Acoustics

The AtlasIED ALX‑4D‑B is a digitally steerable column array loudspeaker designed to perform in highly reverberant or architecturally sensitive environments. With four full-range transducers, each powered by an independent DSP and amplifier channel, this compact column speaker delivers intelligible, directed audio where it matters most. Whether it's used in train terminals, lecture halls, or traditional houses of worship, the ALX‑4D‑B ensures speech and music reach the audience cleanly, without unwanted reflections bouncing off hard surfaces.

Digital Beam Steering for Focused Sound Projection

Equipped with real-time beam steering technology, the ALX‑4D‑B lets you precisely control vertical coverage angles to match the acoustic needs of any space. The acoustic center of the beam can be repositioned across the column’s height, and multibeam functionality enables more than one audience area to be targeted simultaneously. This functionality allows for even sound pressure level distribution, reducing dead zones and echoes without adding hardware complexity.

Networked Audio Integration via Dante and AES

With Dante, AES/EBU, and analog connectivity built in, the ALX‑4D‑B integrates easily into any modern AV installation. It eliminates the need for external audio bridges or protocol converters, simplifying infrastructure and installation. Its onboard networking also supports IP control, giving system designers access to full configuration, remote control, and firmware updates through a unified interface.

Compact Form Factor with Mounting Flexibility

The slim aluminum enclosure of the ALX‑4D‑B blends easily into modern and historical spaces alike. Its corrosion-resistant black finish and included L-bracket kit support both wall-mounted and surface-mounted applications. This allows it to be installed discreetly in lobbies, auditoriums, classrooms, or transportation centers without compromising design aesthetics.

Real-Time Control with Integrated Software Tools

The system comes with integrated software for beam steering configuration, diagnostics, and real-time adjustments. Audio professionals can store up to 24 presets, monitor system health, and interface with AtlasIED’s GCK global communication software. Its real-time telemetry ensures minimal delay and consistent system performance, even under demanding conditions or emergency notification use cases.

Designed for Emergency Communication Compliance

This speaker is engineered for environments that require clear, reliable messaging during emergency or paging scenarios. When paired with GLOBALCOM® control systems, the ALX‑4D‑B supports legislative standards for public safety and voice evacuation applications. Its fast response time, sharp intelligibility, and full system monitoring make it ideal for critical infrastructure.

Scalable Solution for Professional Installations

Though compact, the ALX‑4D‑B is part of a modular family of beam-steering arrays. Multiple units can be stacked or combined into larger configurations without sacrificing simplicity. This scalability makes it suitable for AV contractors working on venues of any size who require precision, control, and consistent output.
