Special note:
The new version has actually been on sale for several months, but I haven't had the time to provide a detailed explanation. Additionally, I invited my good friend JEFF, who is also a senior audio expert, to assist in conducting a very precise sound calibration. The new version has addressed the unreasonable aspects of the original wiring and materials used. After finalizing the design, both the test metrics and auditory experience of the new version have been significantly improved. It has undergone AP testing and surpasses the sound quality of the original model. Audiophiles can purchase it with confidence.
Over the past few years, we have successively referenced various renowned circuit designs, constantly extracting the essence from product designs of various brands and manufacturers. It should be said that each major brand has its own unique understanding of audio circuits, which is reflected in their own products. The same goes for FM's power amplifier circuit. The output circuits of its entire series of products use very easy-to-precisely-match same-polarity power transistors, while the most critical input circuit has extremely high requirements for differential circuit components. This is why its sound can guarantee extremely low distortion and accurate reproduction of the original sound. Therefore, FM's sound stands out among numerous brands. Audiophiles who have used our FM300A should be able to deeply feel this. In this redesign of FM711, we have approached it with a more rigorous and reverent attitude, strictly following the original design concept to complete this product
● Original machine module
All components of the entire machine have undergone rigorous pairing and screening
● Strictly tested by a tester before leaving the factory
● Operating voltage: 220~240V AC / (100~120V AC can be customized)
●Transformer 1000W transformer: Nippon Steel core transformer
● American CMC speaker wiring base
● Aluminum shock absorber foot pin
Technical Features:
1: The FM711-MKII utilizes a high-current capacity, high-speed dual rectifier for its larger power supply with immense power.
2: The new module is used for input and achieves an impressive 100dB, with astonishing suppression effect on common-mode signals.
The common mode rejection test diagram is as follows:
The measured result shown in the figure below is a weak signal of 1.61mV with strong noise. After amplification, it becomes a very clean and distortion-free output signal of 831mV.
3: Huge power to drive the most demanding loads, proprietary discrete circuits utilizing special curve tracing analysis and hand-picked semiconductors, and a superb balanced discrete input stage. The sensor automatically identifies and connects standard, well-balanced, unbalanced, and pseudo-balanced signal sources at the input.
4: Implement multiple protection systems for power amplifiers and speakers, triggering output and automatic reset when errors disappear.
5: Without signal compression, no other negative impacts on the audio signal are possible due to limitations. All audio stages of the protection circuit are completely separated.
6: Output drives any loudspeaker load perfectly, even very low impedance or higher impedance capacitive transducers, with unique dynamic damping effects on loudspeakers, perfect pulse response, and no ringing.
7: The proprietary enhanced-level circuit provides unparalleled music quality. The Grand Prix award-winning circuit technology ensures complete elimination of any form of distortion, regardless of its dynamic or static state, even at the lowest signal levels - an improvement over other designs by magnitude.
8: New mechanical resonance elimination support for FM acoustic isolation, low impedance power supply for infinite rendering, and new high-reliability components help further enhance the expected lifespan.
