This amplifier provides the unwavering confidence and capability required for the most demanding sound environments.
FU-TRA11000 11000W Power Amplifier – High-Efficiency Class H Control
Are you searching for an amplifier that can handle large and demanding events without compromising sound quality? Conventional amplifiers often fall short when systems need both very high power and consistent reliability in professional environments. When a lack of headroom or audible distortion appears during a crucial event, the audience’s experience suffers, and the atmosphere you worked to create can be ruined, affecting both your image and your client’s impression.
The FU-TRA11000 11000W power amplifier is built to address exactly these situations. It delivers 2x2600W at 8Ω, 2x3100W at 4Ω and up to 11000W in bridged mode, providing the power reserves required for large rooms, high-output speaker systems and demanding program material. Its Class H output circuitry is designed for stable, efficient operation under load, while a damping factor of 300 and a slew rate of 35V/µs help maintain firm control and fast response across the full audio range.
With a signal-to-noise ratio of 93dB and THD+N below 0.03% at 8Ω, 1 kHz, the FU-TRA11000 keeps your audio clean and detailed even at high levels. Crosstalk of 70dB at 8Ω, 1 kHz keeps channels well isolated for stereo or dual-zone use, and the 3U, 42kg chassis (515 × 485 × 133 mm) offers robust construction suitable for professional racks. For DJs, corporate AV teams and performers who need power, clarity and control in one unit, this amplifier provides a high-capacity solution ready for serious events.

Why Choose FEUR for your FU-TRA11000?
FEUR designs the FU-TRA11000 11000W power amplifier to offer very high output and controlled performance in a clearly specified, professional package. Power ratings of 2x2600W at 8Ω, 2x3100W at 4Ω and 11000W bridged allow system designers to drive large full-range enclosures, clusters or sub-heavy configurations from a 2-channel frame. Class H output circuitry supports efficient operation at these power levels, helping the amplifier handle demanding program material during long events.
The technical performance of the FU-TRA11000 11000W power amplifier is tuned for clean, predictable sound: a 93dB signal-to-noise ratio, THD+N below 0.03% at 8Ω, 1 kHz and a damping factor of 300 support low-noise, low-distortion reproduction with firm loudspeaker control. A slew rate of 35V/µs and crosstalk of 70dB at 8Ω, 1 kHz help maintain clarity and channel separation in stereo or dual-zone applications. These specifications give engineers confidence when deploying the amplifier in critical events.
From a practical standpoint, the 3U, 42kg chassis with dimensions of 515 × 485 × 133 mm integrates easily into standard racks for rental, touring or fixed installations. Selectable input sensitivity (0.775V/1.0V/1.4V) and balanced/unbalanced input impedance options simplify matching the FU-TRA11000 with different consoles and processors in corporate, live or presentation systems. For professionals who need a high-capacity Class H amplifier that combines clear power ratings, solid control figures and flexible integration, FEUR positions the FU-TRA11000 as a reliable choice for demanding audio setups.

Q: What makes the TRA Series reliable in power-challenged regions?
A: The toroidal transformer power supply minimizes magnetic interference and delivers stable voltage to the amplifier circuitry even when mains power fluctuates — a key advantage in Latin America, the Caribbean, and other regions with variable grid quality.
Q: What is the efficiency advantage of Class H topology?
A: Advanced Class H operation achieves over 90% efficiency, generating significantly less heat than Class AB designs — ideal for extended operation in live performance venues.
Q: Can TRA amplifiers run in bridge (mono) mode?
A: Yes. Bridge mode (BLT) is supported on all models, nearly doubling available power output for demanding applications such as large subwoofer stacks.
Q: What are the primary applications?
A: Live sound reinforcement, recording studios, broadcast facilities, arenas and auditoriums, houses of worship, and home theater installations.
