Differences between 711 Standard Edition and Deluxe Edition:
Standard Edition: 13980 yuan, domestic customized 1000W ring cow, 19610 module, 500W per channel
Deluxe Edition: 18980 yuan, the original German 1000W ring cow, the third generation 19610HR module, 500W per channel
The difference between 711 and 411:
711:Power 500W (4 ohm load), 7 pairs of power tubes, 1000W ring cow, 20 kg, can drive most difficult speakers.
411:Power 300W (4 ohm load), 6 pairs of power tubes, 600W ring cattle, 30 kg, can drive most common speakers (maximum load power is within 300W).

A senior player once said such a memorable sentence:&Amp;ldquo;If the prices of Krell, Cello and other equipment are too expensive, then the price of FM is simply damaging! ”What does FM have fever equipmentHow "suppressing the world", the sub-flagship stereo rear 711MKII is priced at 630,000, and the sub-flagship front 266MKII is priced at 590,000. . .
FM was originally a Swiss manufacturer specializing in broadcasting professional audio products. After entering the HI-END field, it did nothing but do two things and took out the manufacture of Swiss watchesSpirit, all products are precisely manufactured by hand, and audio equipment is treated as a work of art. All FM research and development work and product production are done in the factory.It is the opposite of the fashionable management method of modern industry. All components purchased by FM are inward rather than outward, because FM believes thatOnly when every detail of every link is under continuous and strict quality control measures, accuracy and quality can be truly guaranteed.
During the entire assembly process, each component is tested before assembly. After the component is installed, each module and circuit board are connected againSubject to inspection, testing and adjustment; when assembling the equipment, each stage of the test and adjustment is continuously repeated. After the equipment is completed, test and adjust the whole machine, Long “pot”(Burn-in)And passed the seismic test. Because the production of FM equipment consumes a lot of manpower and material resources, such labor is very expensive in Switzerland.In high places, FM insists on manual testing, so the price is much more expensive than general equipment.
Product introduction:
Ledi reproduces the Swiss FM711MK3, the original machine is 630,000 yuan, the sound is warm, natural and smooth, with good thrust, control, dynamics, and strong driving forceAnd plenty of energy can drive most difficult speakers.
1 Input module: Completely crack the original 19610HR input module, the channel separation is as high as 100dB (the first generation 19610 module is only 80dB measured), Using discrete components Class A circuit architecture to achieve true fully balanced input. HR module can eliminate clutter interference, strong control, sense of hierarchy,Better analytical ability and sense of presence.
2 Power supply: Improved to a larger-scale power supply double bridge rectifier. The original German 1000W toroidal transformer has sufficient power supply. Germany FRAKO 6800μF filter capacitor; the feedback capacitor is developed by us and capacitor manufacturers for a year, using audio aluminum film, adding a similar Black GateThe polymer is tuned, and both distortion and timbre are greatly improved, and it can be fully realized in the violin and piano.
3: Completely decrypt the original high-power amplifier tube and pair the transistors according to the original parameters.
4 original selection: We aim at some key sensitive components according to the original factory and circuit characteristics, first use the AP to pass the test and then use it. ChoosingThe high precision of the parts leads to large waste material loss and long debugging time. The transistors used at all levels are strictly matched with the transistor graph visual instrument according to the working point. The coreThe resistors are paired with TH288E to achieve the consistency of the output after adjustment.
5 debugging:Full manual debugging to make the precision output level and balance control consistent; the second precision debugging is carried out after 36 hours of warming up to achieve the bestFinal precision effect.
