While other turntables use a quartz servo system, the JVC QL-F320 has a Double Servo Quartz control system. It works together with a coreless, cog-free DC servo motor to give you unexcelled speed accuracy.

We've also given the tonearm a special touch: it's of low mass design for better tracking, and mounted on a separate subchassis (Independent Suspension system) for better resistance to acoustic feedback.

Our high performance motor and quartz control system are fully responsible for the top performance of the QL-F320 - only 0.025% wow and flutter. You'll hear absolutely no audible variations in pitch - even when playing new digitally mastered and direct to disc records.

Nearly all records have warps that lead to distortion. The QL-F320 minimizes warp induced distortion with it's new lightweight tonearm. Its higher resonance frequency does not reinforce warp frequencies, so mistracking rarely occurs. Sensitivity and physical strength are also higher - factors often overlooked.

In addition, the center of gravity of the tonearm is lower than normal and the pivot fulcrum is located at almost the same vertical height as the stylus tip. This design reduces effective wow and flutter, and improves tracking ability.

The tonearm and motor of the QL-F320 are mounted on a separate chassis that floats freely within the cabinet. This improves the turntable's resistance to acoustic feedback; even if the turntable is located near a speaker, the arm and platter remain nearly immune to vibration.

Operating the QL-F320 couldn't be simpler; there's never a need to touch the tonearm. Whenever desired, one record side may be repeated continuously by just pressing the Repeat button. Automatic operation makes records and stylus last longer, too.
