Resolution Series 266-MKII, 266-MKII "R" and 266-MKII "RC"

Success unequalled: the FM 266-MKII R true balanced Line Stage / Preamplifier

The new "R" and "RC" versions of the FM 266-MKII are redefining the absolute in line stage design. Shown first time in May at the Hifi Deluxe exhibition in Munich they caught the eyes of admirers.

  

The "R" version of the FM 266-MKII uses a beautiful remote control that is hand crafted out of selected wood. This remote is carefully crafted at our factory in Switzerland.  

 

 

 

FM 266-MKIIRC with unique ARC circuits
The phenomenal Acoustic Resonance Correction circuits located on the front panel. A tremendous improvement in reproduction in any room is guaranteed.

The "RC" version of the FM 266-MKII includes this remote control and additionally features the phenomenal ARC - Acoustic Resonance Compensation - circuits, yes, exactly the same that are incorporated in the 

FM 268C.

 

 

 

 

 

 

 

Located behind a protective panel on the front of the FM 266-MKIIRC the ARC circuits can guarantee amelioration of reproduction by eliminating room resonances.

Room modes occur when parallel surfaces create one or more pronounced resonance peaks that are superimposed on the actual music resulting in boominess and poor low and low-mid frequency definition.
The ARC is also helpful when there are resonances from other sources in the room (e.g. air conditioning or any other resonating surface or room component).

  • The set up of the ARC circuits requires knowledge and test equipment. Our official distributors perform this service at no charge to our clients.

 Of course, all characteristics that have made the FM 266-MKII unique have been kept. 
The MKII version is the continuation of the highly esteemed FM 266. Who would ever have imagined what success the FM 266 series would achieve in its 24 years of continuous production? A unit perfected so carefully that it never required a single modification or correction whilst providing a performance so far ahead that others did not even try to challenge it. 

New parts have become available that - together with advanced insights due to continuous R+D - allow the first major amelioration. The refinements manifest themselves in substantial improvements - heard quickly.

 

True-impedance attenuators

Compatibility with any domestic or professional equipment is assured via ultra high accuracy true balanced inputs including optimization switches
Compatibility with any domestic or professional equipment is assured via ultra high accuracy true balanced inputs including optimization capabilities.

New switchable linear impedance attenuators are on balanced inputs I, II and III.

These are very useful with today's high level components (CD/DVD players/download servers/converters etc.) some of which produce excessively high output voltages - often 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 preamplifier.
The new input attenuators of the FM 266 MKII series lower the excessive levels whilst guaranteeing perfect balancing (not an easy feat!). This in turn results in optimized gain structure of the system and ideal Level Control setting (around 12 o'clock position for normal listening levels).

 

 

 

Optimal gain structure

Higher flexibility in obtaining optimal system gain structure via adjustable gain

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 266-MKII.
This allows more flexibility in system gain optimization. Any system can be set to an optimal gain structure - which improves total system performance. 

 

 

 

 

 

 

 

"HR" modules

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.

 

 

Type 19200

...the new HR output circuits

The new "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 a superb level of reproduction and reliability.

Never before has such a level of accuracy been achieved.

 

 

 

 

 

 

 

Resonance-eliminator support

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 which are absorbed.

 

 

 

 

 

Hand-selected

Meticulous attention in every detail
Meticulous selection in every stage

Purpose built testing equipment allows the precision Output Level and Balance controls to be carefully hand selected.

In combination with top class interference rejection and ultra efficient shielding the highest level of musical accuracy is achieved.

 

  

 

 

 

 

 

Long-term reliability

Details that make the difference in long-term reliability.
Details that make the difference in long-term reliability.

Small detail make all the difference. To the trained eye these are noticeable in many places. Here precision soldered flexible inter-pcb connections improve protection from vibration damage and potential contact problems in harsh environments and in transport mishandling.
