FBT Vertus 4x CS-1000 Active PA System 4000W, Choice of Colour

Combining 4 x CS 1000 Systems together delivers a whopping 8000 watts in a tiny footprint. Inverting the top satellite on each stack assures perfect phase cohesion.

The Vertus CS1000 compact line array combines maximum performance with a modular, scalable approach. Its lightweight but sturdy construction blended with distinctive engineering has delivered a system that can be deployed on stage within minutes, or discreetly integrated into the most applications.

A bi-amplified design, the system comprises a long excursion 12” bass reflex subwoofer and a passive mounted satellite, linked via a Neutrik SPEAKON connector and equipped with six full-range neodymium 3” drivers. Onboard the subwoofer is a Class-D, two channel amplifier, complete with switch-mode power supply, delivering 600W RMS to the subwoofer and 400W RMS to the satellite, both of which are housed in birch plywood enclosures. For ease of use, a storage compartment is provided within the subwoofer enclosure to securely house both the satellite speaker and its supplied mounting pole for storage and transport. A dedicated locking system holds all of the equipment in place.

Comprised of three sections, the pole allows users to alter the height of the satellite to suit their requirements, while a custom joint provides continuous vertical adjustment to ensure precise coverage in every venue. The slim proportions of the satellite facilitate a wide horizontal dispersion of 110°, while the precision placement of the six 3” drivers to form a J-array creates a vertical dispersion of 30° (+10° / -20°).

By stacking the two subwoofers and locking the two satellites together end-to-end (via optional hardware), the maximum SPL of the overall system is raised by 6dB. Coverage is also extended – although the horizontal dispersion remains consistent, vertical dispersion increases to 40° (+20° / -20°)

Other features ensure ease of use and a rugged build quality. The subwoofer is equipped with aluminium handles complete with a rubber insert to guarantee a comfortable grip – transporting the entire system, including the subwoofer, satellite, mounting pole, joint and all cables, is both convenient and comfortable. The fan-less amplifier module is protected by diecast aluminium, while onboard DSP offers a choice of eight dedicated presets.

Finally, the Vertus CS1000 is compact in dimension but big on sound. The volume of the satellite can be adjusted in accordance with the subwoofer in 8 steps between -4.5 / +5dB range, while a selectable high-pass filter ensures optimum reproduction.
