Note:
1: 1811, 118 are pure post-levels and need to be used with pre-levels.
2: Due to the higher power of the rear stage, you must wait until the warm-up is completed and the switch button light is always on before adjusting the front-stage volume.
3: The parameters related to power are all working conditions with 4 ohm load.
Package express, send massive non-destructive resources. Ledi directly engraved the Swiss FM1811 rear stage, 900W per channel, completely cracked the original 19210 module, customized 3000W square transformer, 12 pairs of power tubes, 4 10000μF 100V filter capacitor. Strictly follow the original machine testing and production links. The components are strictly aging, tested, and paired; the modules are paired before installation, and all working points refer to the original machine; before leaving the factory after 100 hours of burn-in; each unit is independently numbered, and the module parameters are archived for future maintenance. The sound is warm, natural and smooth, with good thrust, control and dynamics. The strong driving force and abundant energy can drive most difficult speakers. 1 set of balanced input, adjustable input level. The random device comes with AP test data.

About FM Acoustics:
Swiss FM Acoustics (hereinafter referred to as FM) may be the most expensive HI-END brand in the world. Even experienced veterans may not have heard of FM audio equipment, because the price of this guy is really outrageous. A senior player once said such a memorable sentence:“If the prices of Krell, Cello and other equipment are too expensive, then the price of FM is simply damaging!”How much fever equipment does FM have?“Hurting the world”Well, the sub-flagship stereo rear-level 711MKII is priced at 630,000, and the sub-flagship pre-level 266MKII is priced at 590,000. . .
FM used to be a Swiss manufacturer specializing in professional audio products for broadcasting. After entering the HI-END field, it has done nothing but the spirit of making Swiss watches. All products are manufactured with precision by hand, and audio equipment is treated as a work of art. , All FM research and development work and product production are carried out in the factory itself, which is the opposite of the fashionable management method of modern industry. All components purchased by FM are carried out inward rather than outward, because FM believes that only every detail of each link is under continuous and strict quality control measures, and accuracy and quality can be obtained. The real guarantee.
In the entire assembly process, each component is tested before assembly. After the component is installed, each module and circuit board is inspected, tested and adjusted again; when assembling the equipment, each stage of the test is repeated. Tuning. After the equipment is completed, the whole machine is tested, adjusted, and“Pot”（Burn-in）And passed the seismic test. Because the production of FM equipment consumes a lot of manpower and material resources, FM insists on manual testing in a place with extremely high labor costs such as Switzerland, so the price is much more expensive than ordinary equipment.
