This direct-engraved FM711MK2 is a milestone product for us!

In the past few years, we have engraved various famous machine circuits, and have been constantly absorbing the essence of product design from various brand manufacturers. It should be said that each big brand has its own unique understanding of audio circuits and reflects it in its own products. The same is true for FM's power amplifier circuit. The output circuits of its entire series of products use the same-polarity power triodes that are very easy to accurately match, and the most critical input circuit has extremely high requirements for the components of the differential circuit. This is why its sound can ensure extremely low distortion and accurate restoration of the original sound. Therefore, the sound of FM is unique among many brands and is extremely expensive. Audiophiles who have used our FM300A should be able to feel this deeply. We used a more rigorous and awe-inspiring attitude to complete the FM711 replica this time, and completed this product in strict accordance with the design concept of the original machine.

FM711 technical features:

1: FM711-MKII has huge power of larger scale power supply is adopts high current capacity of high speed double rectifier.

2: New modules are used for input, achieving an amazing 100dB (!!!) rejection of common mode signals (interferences such as noise, hum, must be eliminated before the amplification stage). They put FM 711-MKII anti-interference. This common mode rejection ratio is achieved without rejecting cheap op amps and can be individually fine-tuned discrete class circuits to ensure that the final product is called FM acoustic.

The common mode rejection test diagram is as follows

3: Huge power to drive the most demanding loads, proprietary discrete circuitry using special curve tracer analysis and hand-selected semiconductors, superb balanced discrete class input stage. The sensor automatically recognizes connection standards and well-balanced unbalanced and pseudo-balanced signal sources at the input.

4: Multiple protection systems for amplifiers and speakers trigger output and auto reset when error disappears.

5: No signal compression, limiting nor any other negative influence on the audio signal is possible. All audio stages of the protection circuit are completely separated.

6: The output drives any speaker load perfectly, even very low impedance or higher capacitance sensors, the unique dynamic damping of the speaker effect perfect impulse response and no ringing.

7: Proprietary Enhanced Stage Circuitry Provides unrivaled musicality, Grand Prix winning circuit technology ensures that any form of distortion is completely unaffected by its dynamics or statics, even at the lowest signal levels - improving other designs by magnitude.

8: New mechanical resonance elimination support for FM acoustic isolation, low impedance power supply for unlimited rendering, new high reliability components help to further improve life expectancy.250W 8 ohms 500W 4 ohms

The finalized new version has greatly improved test indicators and listening experience. It has passed AP testing and strives to achieve a unique sound. Audiophiles can buy it with confidence.

1. The reason why classic aircraft are classic is that in a specific era, they used special components made of customized materials, perfectly integrating art and technology, which led to the emergence of a generation of famous aircraft.
2. At the audio exhibition, many friends had a lot of confidence in our products after listening to them. At the suggestion of several senior music enthusiasts, we made a 711 customized amplifier. In order to make this product well and make the sound and materials of this machine unique, we decided to use the best components in the company to make this machine.
3. The overseas transistor supplier played an indispensable role in finding a batch of brand new gold-sealed triodes produced in 1981. You should know that the peak period of audio development also started from this era, and it slowly declined until around 2000. In that era, many factories customized components to make their products unique, including many world-renowned audio factories in Switzerland, Germany, Britain, the United States, etc.

The frequency characteristics and parameters of this pair of tubes are very good, and the withstand voltage is extremely high, which just meets the high-voltage working mode of FM. After we got the samples for testing, several audiophiles with golden ears conducted 3 rounds of blind listening, and everyone gave very high evaluations. Whether it is the high frequency, mid-frequency or low frequency of the sound, it is impeccable, reflecting an unprecedented sense of relaxation and delicacy. The music without any sense of oppression comes to the face, and it is amazing as soon as it is turned on, and people completely forget the existence of the sound system. So we decided to use these tubes to make some different machines to give back to those friends who have always supported us.
