Direct drive used to be the "state of the art" in turntable technology. Not any more. Now there's the Fisher MT6225 linear motor turntable.
120 poles vs. 12 in the old kind.
Conventional direct drive motors use a rotor divided into a number of "poles" (like sections of a pie). The magnetic field coils rotate the platter by alternately pushing and pulling on these poles. Typically, 12 push/ pull cycles produce one revolution of the motor. Unfortunately, 12 poles produce a certain amount of flutter, vibration, and "togging" In the Fisher MT6225 we solved these problems by re placing the conventional armature with a ferrite band around the platter containing not the Id 12. but 120 poles. So instead of 12 strong pulls per revolution, the platter receives 120 gentle tugs. The payoff in smoothness is obvious.
Phasing out flutter But we weren't through. We added a unique drive system with three separate field coils driven 120° out of phase, so their drive impulses overlap to pro duce constant, linear motion. With incredibly low wow & flutter (0.03%) and rumble (-70dB). Perfect, for all practical purposes.
Your last turntable?
As revolutionary as the linear motor system is, it's also extremely simple and reliable. With only one moving part (the platter) and solid state electronic control, there simply isn't much to go wrong. So the MT6225 will perform as great on its 10,000th record as on the first.
You can own this Fisher engineering masterpiece for only about $200, complete with superbly balanced tonearm base and dust cover. Or get linear drive with a slightly different tonearm for just $130 -- in our MT6224.
Either way, it's an investment you'll always be happy with even after you've played your 10,000th record.
Other Fisher turntables start at $130. Fisher components are available at selected audio dealers or the audio department of your favorite department store.
