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, 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 amelioration - after 17 years. The refinement manifests itself in some smaller modifications but also some more substantial improvements - as described below.
New switchable linear impedance attenuators are on balanced inputs I, II and III.
These are very useful with of todays 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 it 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 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 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.
The new HR modules (19610) are used on the inputs. They help to achieve an astounding 100dB of rejection of Common Mode signals (such as interference, hum, noise etc.) making the FM 266-MKII immune against interference. 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.
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.
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 and converted into thermal energy.
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.
