Quartz Locked Automatic Turntable (1980) with electro-dynamic servo control tonearm
The QL-Y3F is a fine combination of traditional workmanship and high technology JVC features.
Foremost of these features is the E-D servo system that controls horizontal arm movement.
A coreless linear motor with a horizontal velocity detection system is used to combat resonance which can cause intermodulation distortion.
Also featured on the QL-Y3F are the same double servo quartz control system and cog-free coreless DC servo motor design used in our more costly turntables, providing impeccable long-term speed accuracy.
Despite all this technology, the QL-Y3F is easy to use thanks to micro-computer controlled fully automatic operation.
The micro-computer, a programmed to order LSI, co-ordinates all circuits and controls for error free, fully automatic operation, including platter start, cueing, lead-in, lead-out and end of play shut-off.
Other features include soft-touch up-front controls, an adjustable height tonearm and LED indicators for speed, quartz-lock and record size.
