The VERTUS CLA 406.2A is a professional-grade, active column line array system engineered to meet the demands of high-output audio applications in touring, fixed installation, and corporate environments. Designed for precise sound coverage and modular flexibility, the VERTUS CLA 406.2A delivers consistent, intelligible audio across a wide range of venues. At the heart of the system are four custom 165mm woofers paired with a neodymium B&C compression driver, ensuring accurate low and high-frequency reproduction. Its integrated Class-D bi-amplification, delivering 600Wrms for low frequencies and 300Wrms for high frequencies, supports powerful and efficient performance. The built-in DSP with eight equalisation presets offers adaptability to varied acoustic settings, making the VERTUS CLA 406.2A suitable for both standalone configurations and larger vertical arrays. Constructed from robust birch plywood with protective features and optimised rigging points, it supports a variety of deployment methods including flown arrays and ground setups. The enclosure design, with a 10-degree inclined top and integrated hardware, enables precise vertical dispersion when combined with other CLA models such as the CLA 206A. Whether deployed as part of a larger touring rig or within a fixed installation, the VERTUS CLA 406.2A provides reliable performance, flexibility in system design, and clarity in sound delivery, making it a valuable solution for audio professionals and integrators.
