Inheriting the classic core design of the flagship FM711, and optimized for modern audiophile systems in terms of size, weight, and appearance, it reproduces the iconic natural FM-tuned sound. High power output of 260W RMS x2 under 4Ω load and 130W RMS x2 under 8Ω load, equipped with push-pull amplification circuitry, an 800W toroidal transformer, and large-capacity filtering capacitors, provides powerful driving force for a variety of demanding speakers.
Fully balanced XLR signal transmission eliminates interference, achieving ultra-low bass coloration, a flat frequency response of 10Hz-30kHz, and excellent high and low frequency extension. A super-high channel separation of 110dB and a damping factor of up to 301 under 8Ω load deliver precise and delicate sound control, restoring a realistic and natural soundstage, accurate sound image positioning, and a warm, mellow listening experience that is comfortable even after extended listening sessions.
A high-quality solid metal chassis with integrated heat dissipation structure and bottom support for 110V/220V dual voltage switching, perfectly compatible with US household power standards.
For audiophiles seeking the pure, transparent, and musical sound of classic Swiss FM audio equipment, the BRZHIFI FM411 pure power amplifier is an ideal high-performance option, offering uncompromising sound quality. We’ve retained 100% of the core circuitry of the benchmark FM711 amplifier, optimizing heat dissipation, housing structure, and component matching to ensure stable operation under heavy loads for extended periods. Each FM411 is meticulously calibrated to eliminate unwanted coloration, revealing every subtle detail hidden in studio recordings, live concert tracks, and classic music collections, creating an immersive listening experience as if you were right in front of the performers. Its all-metal chassis weighs 22.5 kg and features precision-machined heat sinks on both sides for efficient passive cooling, eliminating additional fan noise to your audio system. Whether in the living room, a dedicated listening room, or a home theater, it’s the perfect upgrade for your high-end passive speaker system.
