Digitally Steerable, Multichannel 24-Speaker Column Array Loudspeaker

Ideal Use Cases

The AtlasIED ALX-24D is engineered for precision audio management in acoustically challenging environments, such as public buildings and transportation hubs. Its advanced multibeam steering technology and 24 full-range transducers make it ideal where sound direction is crucial. With a typical throw distance of 190 ft (60 m), this loudspeaker excels in applications requiring extensive coverage while minimizing unwanted sound spillover.

Why Choose This Model

Choose the ALX-24D for its unmatched control over sound projection. The digitally variable vertical opening angle from 5° to 40° allows for tailored sound dispersion, accommodating both narrow and wide coverage needs. Vertical steering from +40° to -40° provides additional flexibility, enabling precise sound direction without altering the physical placement. The model’s multibeam capability enhances its adaptability for complex audio environments.

Equipped with 24 PWM Class-D amplifier channels and 24 DSP channels, this model offers robust processing power. The neodymium full-range transducers, each featuring a coated NRSC fiberglass membrane, ensure high-quality audio output across the spectrum.

Installation and Integration

The ALX-24D supports various input formats, making it versatile for integration into both networked and traditional audio systems. It features two Dante/AES67 inputs, two analog line inputs, and two AES/EBU inputs, with an analog sensitivity of 15 dBu RMS. The power supply range of 94–264V ensures compatibility in diverse electrical settings.

With dimensions of 95.9 inches in height, 4.7 inches in width, and 6.6 inches in depth, and a weight of 66 lb, the speaker’s installation should consider these specifications for proper placement and support. Although mounting hardware details are not specified, it is advisable to verify these requirements for your specific setup.

Performance Highlights

The ALX-24D boasts a frequency response from 100 Hz to 18 kHz at -3 dB, with an impressive output of 103 dB at 30 m. Its 120° horizontal dispersion ensures broad lateral coverage, while the vertical pattern is adjustable to suit different environments. The low-frequency beam control limit stands at 250 Hz, defining the effective range for beam steering.

This model’s 24-channel amplification and processing capabilities, combined with its columnar design, deliver effective steering, opening-angle adjustments, and multibeam operation. A refresh rate of 100 Hz supports its dynamic audio performance.

What Makes It Different

The ALX-24D distinguishes itself with its comprehensive digital control within a compact column-array design. Its ability to adjust the vertical opening angle and steering digitally, along with multibeam capabilities, sets it apart from traditional fixed-pattern systems. This adaptability makes it highly suitable for diverse acoustic challenges.

Its input versatility further enhances its appeal. The combination of networked audio (Dante and AES67) and traditional connections (analog line and AES/EBU) allows seamless integration into a variety of audio setups, catering to both modern and conventional systems.

Final Assessment

The AtlasIED ALX-24D is a sophisticated choice for installations demanding precise audio control over large areas. With its 24-speaker array, Class-D amplifiers, DSP channels, and multibeam capability, it provides an advanced solution for complex public-address environments. Backed by a 60-month warranty, the ALX-24D ensures long-term reliability and performance.
