Introducing the KLH Research X Model Sixty Turntable: A solid triumph in human
engineering.
There are more manual turntables to choose from these days than ever before. And most of the better models share many of the same fine features and specifications.
So why make a turntable? (And we are making it--not just slapping our name on someone else's product. Every part is hand-assembled in our plant in Cambridge, Mass.) The answer is in the product itself.
The Model Sixty is a two speed, belt-driven, transcription quality turntable that combines all of the most wanted features with exceptional performance and a maximum of something we call "human engineering:" What is human engineering? It's designing an electro-optical system that automatically shuts off the turntable at the end of the record and gently lifts off the tonearm. This is achieved through the use of a light detector resistor (shown here) rather than a mechanical device which would have to be tripped by the side force of the tonearm. Since our system requires no side force, it virtually eliminates all potential distortion and side thrust problems.
Human engineering is designing a special low mass aluminum tonearm and unique low friction pivot block and post assembly to such exacting standards that usage deterioration and performance deviations is all but eliminated.
Human engineering is designing all of the electronic controls into an upright module for incredibly simple and convenient operation. It's also making the controls feel as good as they look.
(Just one touch and you know there's something substantial here.) In short, human engineering is finding out what people want and. need in a product and putting it there. That's why the Model Sixty also features push button electronic cueing, anti-skating control, a discrete suspension system that minimizes rumble, acoustic feedback and vibrations, one piece dynamically balanced platter, 24-pole synchronous motor and every other important feature you could want in a precision turntable.
All for $150.
Now that's human engineering.
The Model Sixty. Another superb new product from KLH Research X a new era in audio.
