Quartz-Locked Fully-Automatic Turntable (1982)
The JVC QL-Y55F attacks unwanted resonance in a new way, actively rather than passively, by means of a sophisticated electro-servo tonearm.
This remarkable tonearm also allows hands off left-right and up-down cueing, and in play adjustment of tracking force, anti-skating and damping.
Matched to this tonearm is an extraordinarily accurate platter drive system.
Speed accuracy is 30 times more accurate thanks to the double servo quartz speed detection system that monitors and adjusts platter speeds with electronic precision.

A tapered, low mass straight arm
