Unequalled success: the FM 266 true balanced Line Stage / Preamplifier
Unequalled success: the FM 266 true balanced Line Stage / Preamplifier

When introduced 16 years ago the FM 266 was a sensation, but not everybody understood the application or need for this unit; the FM 266 was clearly ahead of its time but news about its performance demanded increasing production. Manufactured exactly the same way for all these years it has built a massive following and today is regarded as one of the "highest standard setting" audio products.

The new FM 266-MKII is a refinement of the original version with some additional features and fine ameliorations. Below the description of the original FM 266

  • The only truly balanced preamplifier
  • Proprietary enhanced Class A circuitry
  • CMRR of 100 dB (= 100-1000 times better than other so-called "balanced" equipment)   
  • Passes critical pro float test with flying colours   
  • Unbalanced and pseudo-balanced signals are automatically balanced right at input
  • Each of the balanced input paths has precisely the same characteristics as the other
  • Tremendous headroom and reserves in input signal handling capability (+21dBv!)
  • All input & output impedances are identical and perfectly linear over full frequency range
  • Sensors in the truly balanced outputs automatically optimise performance for balanced or unbalanced loads
  • Fully discrete circuitry using special curve-tracer analysed and listening-selected semi-conductors
  • Zero overall feedback / feedforward
  • Outputs drive any load and long cables with perfect reproduction and stability
  • No more matching problems between electronics and cables
  • No relays type, stepped or inferior sounding digital or optical volume control
  • Proprietary precision Balance and Output Level controls are specially shielded guaranteeing unparalleled freedom from noise & interference.
  • Internal transformer utilises a special dual shield that prevents any stray fields.
  • Extremely low impedance power supply
  • Individual stabilisation inside each module
  • Hand-selected and individually matched components of DIN, IEC & MIL standard
  • Totally modular concept, guaranteeing that the FM 266 does not become obsolete
  • The Resolution Series ® 266 is THE ultra precision high-level preamplification centre, with 6 truly balanced high-level inputs and a precision buffered true balanced tape monitoring loop
