FU-TRA9000 9000W Power Amplifier
The FU-TRA9000 is designed for maximum efficiency under high-power conditions, combining Class H technology with advanced thermal architecture.
FU-TRA9000 9000W Power Amplifier – High-Efficiency Class H Control
The FU-TRA9000 9000W power amplifier is designed for professionals who demand very high output and consistent sound quality from a 2-channel platform. It delivers 2x2000W at 8Ω, 2x2800W at 4Ω and up to 9000W in bridged mode, making it ideal for large corporate events, presentations and live performances where strong headroom is essential. Its Class H output circuitry helps maintain efficiency and stability under load, allowing you to run powerful systems with confidence.
With a signal-to-noise ratio of 93dB and total harmonic distortion below 0.03% at 8Ω, 1 kHz, the FU-TRA9000 preserves detail and transparency even at high levels. A damping factor of 300 and a slew rate of 35V/µs provide firm speaker control and fast response, helping your system reproduce tight lows and clear mids and highs. Crosstalk performance of 70dB at 8Ω, 1 kHz keeps channels well separated for stereo or dual-zone applications.
Housed in a 3U chassis measuring 515 × 485 × 133 mm and weighing 40kg, this amplifier offers robust construction suitable for professional racks. Input sensitivity options of 0.775V, 1.0V and 1.4V, along with balanced and unbalanced input impedance, make it straightforward to integrate the FU-TRA9000 9000W power amplifier with a wide range of mixers and processors. For corporate AV providers, rental companies and event technicians, it is a reliable high-performance choice that can drive demanding speaker systems with precision.

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.
