Quartz-Locked Fully-Automatic Turntable
The QL-F4 has the best of both turntable worlds: platter rotational accuracy and full automatic operational ease. The combined use of a core-less motor, a direct-drive mechanism and the renowned JVC Quartz technology is the secret behind it's performance, and its low wow/flutter of 0.025% wrms.
The QL-F4 features a Quartz servo system which incorporates a precision Quartz oscillator, super servo frequency generator and responsive servo circuit. Its major highlight is the core-less direct-drive motor; this doesn't "cog" and thus assures absolutely smooth and accurate revolution, and leads to low wow/flutter.
The turntable offers the convenience of fully automatic operation. Among its unusually versatile functions are:
(1) Auto-repeat offering from 1 to 6 plays at the twist of a rotary control, with the 'R' setting offering infinite replays
(2) Auto-lead in which raises the tonearm, moves it over the edge of the record, and gently lowers it to the lead-in groove to start playing
(3) Auto-return which sets the tonearm automatically to its rest when a play is completed, then shuts the power off. As a bonus, the moment you move the tonearm manually, the QL-F4 can be operated as if originally designed for manual operation.
Other features include: new gimbal support, one-row strobe, oil-damped cueing, anti-skate control and a low-resonance cabinet.
