FBT Vertus CLA 406.2A

An FBT column designed for modern sound reinforcement

The FBT CLA 406.2 A follows the "Line Array column" approach: a vertical, discreet, and high-performance format designed to provide even coverage and clear vocal presence. Its wooden construction and bi-amplified architecture make it a system suited for professional use where reliability, high-level handling, and sonic coherence are priorities.

What applications is the FBT CLA 406.2 A made for?

This active column is particularly relevant for live performances, voice reinforcement (conferences, corporate events), DJ sets, and installations requiring controlled projection. Thanks to its frequency response rated at 65 Hz to 20 kHz (-6 dB), it aims for a clear and articulated sound with enough foundation for many setups (and the possibility to complement with a subwoofer depending on bass needs).

Its column format facilitates integration on stage, front of house, or in venues where aesthetics matter: the sound source is elevated, improving the perception of mid and high frequencies by the audience while maintaining a compact footprint.

DSP processing, sound reinforcement, and connectivity: efficiency in the field

Speaker configuration: attack, definition, and control

The CLA 406.2 A features 4 x 6.5" speakers (1.5" voice coil) to provide body and projection, paired with a 1.4" B&C driver with a 2.5" diaphragm for high-frequency precision. This architecture aims for a balance between impact, clarity, and coverage, especially useful when seeking a "carrying" sound without harshness.

Built-in DSP: presets and quick adjustment

The DSP offers 8 equalization programs to tailor the sound signature to the context (music, voice, reverberant environment, etc.). The treble adjustment provides a simple and immediate correction to adjust brightness according to the room, listening distance, or content played.

Connections and daisy-chaining: simple and professional

The connectivity is designed for field configurations: XLR inputs and LINK XLR outputs for chaining multiple speakers or columns. Power is supplied via PowerCon input and output, convenient for securing connections and simplifying cabling in temporary installations.

Mounting and installation

The column can be mounted on a 35mm stand socket and includes mounting systems to meet integration and fixing needs. With dimensions of 190 x 1135 x 290 mm and a weight of 28 kg, it is clearly aimed at performances prioritizing professional system performance and stability.
