The FBT VERTUS CLA 604A two-way bi-amplified speaker system incorporates 6 x 4” custom woofer with 1” voice coil and 4 x 1″ neodymium dome tweeter on waveguide. FBT VERTUS CLA604A The internal Class D amplification, 400W for woofers, 100W for tweeters and DSP processor with 4 equalization presets provide unexpected dynamics in a system of these dimensions. The FBT VERTUS CLA604A shall meet the following performance criteria: frequency response of 130Hz to 20kHz, maximum SPL of 125dB. The FBT VERTUS CLA604A provides a DSP with 4 EQ presets. The feature an extruded aluminum construction and the front shall be protected by a heavy duty metal grille. The control panel provides volume, preset, HP filter, sources switch, 3 status led ( on, peak, prt/limit ), XLR input and Neutrik Powercon supply input at the lower part of the column and XLR link and Neutrik Powercon loop out at the higher part. Superior as well as inferior latching system, enables the extension of the lenght of the line array adding CLA 604Amodules for a greater modularity of the system and possibility to angle the columns of ±30° on the horizontal plane. The rapid latching system with pins allows for the expansion of the system, doubling-up CLA 208 SA modules to form a unified column with an absolute and coherent source integration
