PRODUCT DESCRIPTION
The FBT VERTUS CLA604A 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.
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 4EQ 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 NeutrikPowercon supply input at the lower part of the column andXLR 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 thesystem and possibilityto angle the columns of ±30° onthe 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.
The internal Class D amplification, 400W for woofers, 100W for tweeters and DSP
