WELCOME !

The FM 256-RC is the successor of the much revered FM 255-MKIIR.

In nearly 30 years of production the FM 255 series has been a mainstay of FM ACOUSTICS and the most successful line stage.

With the new FM 256-RC the FM 255 MKII-R is now reborn; all of the features are included in the new FM 256-RC.    

PLUS

the inclusion of the very sought-after additional feature; the fantastic ARC (Acoustic Resonance Correction) that provides listeners a much improved auditory experience.

THE ARC - ACOUSTIC RESONANCE CORRECTION
With the unique ARC, massive reproduction improvements can be achieved with any system - and this in any room.

Standing waves are anywhere where parallel surfaces create pronounced resonance peaks (= very sharp Sound Pressure Level (SPL) increases at specific frequencies). These resonances are disturbing as they are super-imposed on any kind of music resulting in poor low and low-mid frequency definition. As these are acoustic standing waves they are present in any listening environment and system and this with any source be it LP's , streamers, CD's, DVD`s, AV components etc.

The ARC circuits are also ideal if there are resonances from other sources in the room, e.g. air conditioning or any other resonating surface or room component.
The ARC circuits are absolutely unique as the entire correction is done with pure analogue circuits and do not interfere with the music. No digitizing,

A/D or D/A conversion is used. The integrity of the existing system’'s reproduction remains 100% intact.

With FM ACOUSTICS singular ARC circuits disturbing resonances can be eliminated. The result:  a much ameliorated reproduction in   any    listening environment.

To allow the opportunity to experience the amazing improvement the ARC brings to any room, contact the official distributors in your area and request a personal demonstration. Or send an email to admin@fmacoustics.com . We will organize that you will then be contacted by our official distributor.

The calibration of the ARC circuits requires specific knowledge and test equipment. Our official distributors will therefore perform this one time set up at no charge for our clientele.

The FM 256-RC features a cute remote that allows the important functions to be controlled remotely.  Handcrafted at FM ACOUSTICS Swiss facility it provides an additional great feature that is unique:

slow  and  fast speed  volume control.

- The upper two controls "FAST" will cause the level to increase or decrease rapidly.

- The lower two controls "SLOW" will cause a more gradual change of level, thereby allowing very precise audio level setting.

New switchable true-impedance attenuators - unique to FM ACOUSTICS -  are included on the balanced inputs. These are very useful with some of today's high level components (download servers/CD/DVD players/converters etc.) that  deliver excessive voltages - often far above the standardized level ratings. Such excessive input levels can overload input stages (not the ones of the FM 256-RC though...). They force the user to set the Level control on the line stage to very low settings, so low that it actually works as an attenuator instead of a pre-amplifier.

The  true balanced input attenuators lower such excessive levels whilst guaranteeing perfect balancing (not an easy feat). This in turn results in optimal Level control setting (around 12 o'clock position for normal listening levels).

To allow optimization of the total system gain - which differs widely from one system to another - further level switches allow tuning of the internal gain of the FM 256-RC. This allows more flexibility in system gain optimization.

Any system can be set to an optimal gain structure - which improves total system performance.

New modules are used on the inputs. They help to achieve an astounding 100dB of rejection of interference, hum, noise etc.) making the FM 256-RC immune against disturbances.

This rejection is not achieved with cheap op amps but with a fine-tuned discrete Class A configuration which guarantees the phenomenal resolution FM ACOUSTICS equipment is world renown for.

New modules are also employed for the true balanced outputs.

These new modules are the result of a multi-year development.

They achieve a superb level of reproduction and reliability. Never before has such a level of accuracy been achieved.

Hand-selection is evident everywhere.

Here are the precision Output Level and Balance controls.

In combination with proprietary interference rejection and singular shielding/grounding techniques the highest level of musical accuracy is achieved.
