This direct engraving FM711MK2 is a milestone product for us!

In the past few years, we have directly carved various famous machine circuits and have been continuously drawing the essence of product design from various brand manufacturers. It should be said that every major brand has its own unique understanding of audio circuits and incorporates it into their products. The same goes for the amplifier circuit of FM. The entire series of products use power transistors of the same polarity that are very easy to pair precisely. The most critical input circuit has extremely high requirements for the components of the differential circuit, which is why its sound can ensure extremely low distortion and accurate reproduction of the original sound. Therefore, the sound of FM stands out among many brands and is so expensive that it is unreasonable. Those who have used our FM300A should be able to deeply feel this. We completed the FM711 replica with a more rigorous and awe inspiring attitude, strictly following the design concept of the original machine to create this product

Technical features of FM711:

1: The larger scale power supply of FM711 mkii with tremendous power is the use of high-speed dual rectifiers with high current capacity.

2: The new module is used for input and achieves an astonishing 100dB (!!!) suppression of common mode signals (such as noise interference, hum, must be removed before the amplification stage). They use FM 711 mkii anti-interference technology. This common mode rejection ratio ensures that inexpensive operational amplifiers can be individually fine tuned to ensure that the final product is called FM acoustics.

The common mode rejection test diagram is shown below

Super strong anti noise interference ability and linearity, effectively solving the problem of precise acquisition and conditioning of small signals:

3: Huge power is used to drive the most demanding loads, proprietary discrete circuits utilize special curve tracing analysis and manually selected semiconductors, and advanced balance discrete input stages. The sensor automatically recognizes the connection standard and provides a balanced and pseudo balanced signal source at the input.

4: Multi protection system for amplifiers and speakers

5: No signal compression, limitations, or any other negative effects on the audio signal are possible. All audio stages of the protection circuit are completely separated.

6: The output drives any speaker load perfectly, even with very low impedance or higher capacitive sensors, and the unique dynamic damping of the speaker results in perfect pulse response and no ringing.

7: The proprietary enhanced circuit provides unparalleled music, and the award-winning circuit technology ensures any form of distortion, completely free from its dynamic or static nature, even at the lowest signal level – improving other designs by size.

8: The new mechanical resonance elimination support for FM acoustic isolation, low impedance power supply for infinite rendering, and new high reliability components help further improve the expected lifespan.
