Digitally Steerable, Multichannel 40-Speaker Column Array Loudspeaker

Ideal Use Cases

The AtlasIED ALX-40D is tailor-made for environments with challenging acoustics, such as public buildings and transportation hubs. With a typical throw of 295 feet (90 meters), it excels in large spaces, delivering sound precisely where it’s needed. The 120-degree horizontal dispersion ensures wide coverage, while the digital vertical steering and adjustable opening angle direct sound efficiently to the intended listening areas, minimizing unwanted reflections.

Why Choose This Model

Choose the ALX-40D for its integrated system that combines 40 PWM class-D amplifier channels with 40 DSP channels and 40 neodymium transducers, providing robust and flexible sound management. Its electronic vertical control, adjustable from +40 to -40 degrees, and variable vertical opening angle from 5 to 40 degrees, offer unparalleled adaptability. The array supports multiple audio formats, including Dante, AES67, analog line, and AES/EBU inputs, ensuring seamless integration into diverse audio systems.

Installation and Integration

Weighing 110 pounds (50 kilograms) and measuring 159.9 by 4.7 by 6.6 inches (4060 by 119 by 167 millimeters), the ALX-40D is compact yet powerful. Its narrow design facilitates installation without compromising on performance. The wide power input range of 94–264V and analog sensitivity of 15dBu RMS for rated output allow flexible deployment. The variety of input options enables easy integration into existing setups, whether networked or analog.

Performance Highlights

The ALX-40D boasts a frequency response of 100Hz to 18kHz at -3dB, delivering clear and balanced audio. Its 110dB output at 30 meters ensures sound reaches every corner of the venue. The 120-degree horizontal dispersion maintains even sound distribution across the audience. The 40 coated NRSC fiberglass membrane transducers, coupled with 40 amplification and DSP channels, enable the ALX-40D’s sophisticated multi-beam architecture.

What Makes It Different

What sets the ALX-40D apart is its comprehensive electronic vertical control and multi-beam capability. This allows users to tailor sound delivery with precision, adjusting between a narrow 5-degree and a broad 40-degree vertical opening angle, while the ability to steer sound from +40 to -40 degrees maximizes coverage flexibility. Its compatibility with both networked and analog inputs makes it versatile for various professional audio setups.

Final Assessment

The ALX-40D is an advanced solution for venues requiring precise beam control, extensive vertical adjustment, and a significant typical throw of 90 meters. Its integrated 40-channel class-D amplification, DSP capabilities, and multiple professional input formats make it ideal for demanding acoustic environments. With a 60-month warranty, it promises reliability and performance in challenging public and transportation settings.
