The "RC" version of the FM 266-MKII additionally features the phenomenal ARC -
Acoustic Resonance Compensation - circuits - yes, exactly the same that are incorporated in the FM 268C.
In a typical rectangular room the 1st (lowest) resonance is occurring at the opposite walls of the room length (this is why it is not a good idea to listen while sitting
close to walls) - in above Graph "P1").
Depending on the size of the room, these resonances can occur anywhere from above 100Hz down to 20Hz (or below for large listening rooms). This resonance is superimposing itself on the actual music which results in a colouration of the original signal.
Larger rooms with correspondingly low room resonance frequencies will be less of an issue as the resonance frequency is below the reproduced audio frequency range and therefore is not agitated.
The result of these objectionable resonant peaks will be poor definition in the low frequency range. In professional studios large bass traps ameliorate such resonances but size, construction limits, costs and lack of flexibility preclude this for home listening environments. With reasonably sized domestic absorbers such low frequencies cannot be attenuated efficiently.
The ARC circuits are also helpful if there are objectionable resonances from other sources in the room, e.g. air conditioning or any other resonating surface or room
components. These certainly have a negative effect on the resulting sound. They may manifest themselves more clearly when the set up of the ARC
is done and then can be dampened.
With FM ACOUSTICS new ARC circuits - all in pure analogue technology - such resonances can be corrected resulting in a much ameliorated reproduction in any listening environment.
The set up of the ARC circuits requires knowledge and test equipment. Our official distributors perform this service at no charge to our clients.

The new "R" and "RC" versions of the FM 266-MKII are redefining the absolute in line stage design.
The "R" and "RC" versions of the FM 266-MKII use a beautiful remote control that is hand crafted out of selected wood at our factory in Switzerland.
Linear impedance attenuators are installed on balanced inputs I, II and III.
These are very useful with today's high level components (converters, download servers, CD/DVD/Blue Ray players etc.) some of which produce excessively high voltages - far above the standardized levels.
Such excessive levels can overload input stages and they force the user to set the Level control on the line stage to very low settings, so low that the line stage actually works as an attenuator instead of a pre-amplifier.
The precision attenuators of the FM 266 MKII series lower excessive levels whilst guaranteeing perfect balancing (not an easy feat!). This in turn results in optimized gain structure of the entire system and optimal Level Control setting.
To allow optimization of the total system gain - which can differ widely from one system to another - further fine tuning can be performed by FM ACOUSTICS distributors. This allows total flexibility in system gain optimization.
Any system can be set to an optimal gain structure - which improves total system performance.
The new HR modules are used on the inputs. They help to achieve an astounding 100dB of rejection of Interference, hum, noise etc.) making the FM 266-MKII immune against such negative influence.
This outstanding interference rejection ratio is achieved not with cheap op amps but with fine-tuned discrete Class A circuit configurations guaranteeing the ultimate resolution in the unique FM ACOUSTICS way.
"HR" type 19200 modules are employed for the true balanced outputs. These new HR modules are the result of a multi-year development.
They achieve an absolutely superb level of reproduction - and reliability.
Never before has such a level of accuracy been achieved.
To avoid negative influence from spurious resonance and guarantee positive stability the FM 266-MKII employs unique resonance-eliminator supports.
These isolate the unit from potential resonances.
Purpose built testing equipment allows the precision Output Level and Balance controls to be carefully hand selected for ultimate performance.
In combination with top class interference rejection and ultra efficient shielding the highest level of musical accuracy and freedom of any non music-related signals is achieved.
Small detail make all the difference.
To the trained eye these are noticeable in many places.
Precision soldered flexible inter-pcb connections protect from potential vibration damage and contact problems this even in harsh environments.
