The FBT Vertus CLA 604A is a bi-amplified active column line array designed for high-fidelity sound reinforcement. Constructed from extruded aluminum, the cabinet houses six 4-inch custom woofers and four 1-inch dome tweeters on a waveguide. This configuration provides a wide horizontal and narrow vertical dispersion for improved acoustic control in reverberant spaces. Internal Class D amplification delivers 400W for low frequencies and 100W for high frequencies. Integrated digital signal processing offers eight equalization presets to adapt to various environments and applications. The modular design allows for easy vertical coupling to increase sound pressure levels and directivity. Its slim architectural profile makes it ideal for permanent installations and professional mobile PA setups.
