I purchased this in the early 1980s and never completed the set up for which it was intended.  It has sat on my shelf ever since.  It is now time to find it a new home.
From FM Acoustics web site:

  • The FM 600A was introduced in 1977 when a power amplifier for professional applications with somewhat lower power was requested. In its three versions it was manufactured for over 20 years.
  • In the late 70ies, speakers with lower impedances came on the market and consequently more drive capability of the power amplifier was required. Specially for such applications, the 'LI' (Low Impedance) versions were introduced. FM ACOUSTICS were the only high-power amplifiers remaining absolutely stable and transparent while being able to drive impedances of 2 Ohms with unprecedented quality. They became a wide success.
  • When speaker impedances dropped further, even more drive capability was required. The 'ULI' (Ultra Low Impedance) versions were introduced.
  • It has been remarked that no other brand ever came close to these flagships used in studios, with musicians on stage and in private homes. Over 90% of all FM 600A's and FM 800A's that were manufactured are still in regular use today, indeed a rather rare occurence in audio. FM ACOUSTICS continuously invests in a tremendous parts stock and has kept available these parts over all these years, so even today these amplifiers can be kept functioning perfectly.
  • Even complete restorations of products are performed. While this is a loss-making endeavour, we keep providing this service to our clients. After all, these amplifiers are part of our heritage.
