The ultimate dream machine: the FM 268C true balanced Line Stage including the new ARC circuits...


 FM ACOUSTICS introduces the FM 268 C.
The ultimate dream machine in audio.

 All characteristics of the time honored FM 268 have been kept.
Now with one very important new feature:


Unique ARC (Acoustic Resonance Compensation) circuits increase listening pleasure and realism by elminating or reducing room modes and other resonances.*



A wealth of singular characteristics

...and the unique Harmonic Linearizer
...and the unique Harmonic Linearizer


  • Incorporating FM ACOUSTICS' singular Harmonic Linearizer.
  • Proprietary enhanced Class A circuitry.

  • Absolutely unmatched freedom from noise, hum, RFI and interference (= 100-1000 times better than other so-called "balanced" equipment).

  • Single ended and pseudo-balanced signals are automatically balanced right at the inputs.

  • Tremendous headroom and reserves in input signal handling capability (+21 dBv!).
  • All input and output impedances are identical and perfectly linear over full frequency range.

  • Outputs automatically optimize performance for balanced or single ended loads.

  • Fully discrete circuitry using special curve-tracer analysed and listening-selected semiconductors.

  • Zero overall feedback/feed-forward.

  • Outputs drive practically any load and very long cables with perfect stability.

  • No more matching problems between electronics and cables.

  • No stepped, relay type or inferior sounding digital or optical volume control.

  • Internal transformer utilizes a special dual shield that prevents stray fields.

  • Built-in extremely low impedance power supply.

  • Multiple stabilization and protection from mains voltage variations.

  • Hand-selected and individually matched components of DIN, IEC & MIL standard.

  • Modular concept, guaranteeing that the FM 268C does not become obsolete.

  • The Resolution Series ® 268C is THE ultra precision Control Center with six truly balanced high-level inputs plus the new ARC (Acoustic Resonance Compensation) circuits and FM ACOUSTICS' unique
    Harmonic Linearizer.




*   The ARC minimizes room modes and other resonances:


Room modes are anywhere where parallel surfaces (like in almost any room) create one or more pronounced resonance peaks. These resonances superimpose themselves  on the actual music resulting in boominess and poor low-mid frequency definition. With FM ACOUSTICS new ARC circuits - all done in pure analogue technology - such resonances can be eliminated.


The result:  a much ameliorated reproduction in   any    listening environment. 


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 specific knowledge and test equipment. Our official distributors will therefore perform this service at no charge for our clientele.
