FU-A6K | 4000W x 2 @ 2Ω | 6000W Bridge Power for Demanding Multi-Zone Systems

The FU-A6K 6000W power amplifier is built for audio professionals who need serious headroom in compact racks, whether for live events, fixed installations or complex multi-zone systems. With up to 4000W per channel at 2Ω, 3700W per channel at 4Ω and 3000W per channel at 8Ω, it delivers the muscle required to drive large PA speakers and subwoofers without strain. In bridge mode, the FU-A6K reaches 6000W at 4Ω, making it a powerful solution for high-demand low-frequency channels and main arrays.

Behind the performance, the FU-A6K uses high-technology, energy-saving circuitry and a follow-up DC-DC converter to maximize efficiency while protecting your investment. The 2U steel chassis with aluminum front panel, red copper heat sinks and intelligent temperature control with variable-speed cooling fan keep the amplifier running cool under stress. SMT production, “Super A class” inspired output stage behavior and carefully designed power rails help maintain clarity and punch even when the system is pushed hard night after night.

For installers and rental companies, the FU-A6K 6000W power amplifier is a versatile workhorse that adapts to different system designs and impedance loads. It can serve as the backbone of a demanding main PA, feed multiple zones in a complex installation or handle subwoofer duty in bridge mode, all from a single 2U frame. If you need maximum and efficient power for more demanding systems and complex multi-zone configurations, the FU-A6K provides the performance, reliability and flexibility to take your sound to the next level.

Professional Applications

• Live Sound PA Systems: Main left/right amplification or dedicated subwoofer power for concerts and events.
• Fixed Installations: Stadiums, arenas, clubs and large venues requiring high output with stable 2Ω capability.
• Multi-Zone Systems: Complex distributed audio where one amplifier must feed several speaker lines with different impedances.
• Touring Racks: Compact 2U form factor ideal for mobile racks where weight and space are limited.

Why Choose FEUR for your FU-A6K?

FEUR designs the FU-A6K 6000W power amplifieras a high-power tool for real-world professional use, combining serious wattage with efficient, environmentally conscious engineering. High-technology circuitry, follow-up DC-DC conversion and SMT construction mean you get stable output at 2Ω, 4Ω and 8Ω without sacrificing reliability, even in systems that run at high levels for many hours. The robust 2U steel chassis, aluminum front panel and new red copper heat sinks are built to withstand transport, intensive use and high ambient temperatures, making the FU-A6K a long-term investment instead of a short-lived commodity. For projects where equipment failure is simply not an option—festivals, churches, clubs and large events—this kind of mechanical and electronic robustness becomes a key differentiator

For contractors and integrators, the FU-A6K simplifies system design by covering multiple roles from a single amplifier frame: stereo main channels, subwoofer channels in bridge mode, or multi-zone feeds in large installations. This versatility reduces the number of different amplifier models needed in a project, which in turn simplifies wiring schemes, spare parts planning and future expansions. Intelligent temperature control and variable-speed fans help reduce noise in quieter environments like theaters and houses of worship, while still providing the cooling needed for demanding shows and high-SPL venues. When combined with clear labeling and consistent rear-panel connectivity, the FU-A6K becomes a practical choice for teams that need to deploy, reconfigure and service systems quickly in the field.

Rental companies and production houses benefit from a versatile amplifier that can be easily reconfigured between events, maximizing utilization and return on investment. A unit that one weekend feeds a pair of subwoofers in bridge mode can, the next weekend, power several full-range zones in stereo, without changing the core rack layout. Standardized on FEUR amplification, inventory management becomes easier: technicians conocen el comportamiento térmico, la respuesta dinámica y las protecciones de la etapa, lo que acelera tanto el montaje como la resolución de problemas. In the long run, choosing FEUR for your FU-A6K means having a trusted amplification platform that grows with your catalog of speakers and your portfolio of venues, instead of constantly mixing and matching brands with different behaviors and service policies.
