JVC QL-Y5F

Quartz Locked Fully Automatic turntable (1980)

JVC QL-Y5F

Description

A top model from the JVC range, the QLY5F incorporates this company's version of the electronic tonearm using linear force motors.

Any vibrating system utilizing mass and compliance has a resonance point. Therefore, the same applies to the tonearm used in a turntable.

Tonearms now sold on the market possess a resonance frequency at around 5-10Hz. This resonance frequency has a great effect on the reproduction of middle and low frequency ranges.

In addition, warped and/or off-center records, and/or the external vibrations of it make the tonearm vibrate, thus resulting in a modulation of the sound groove signals when the sound groove is being reproduced.

The electro-dynamic servo tonearm employed on the JVC QL-Y5F has been developed to solve these problems.

The vibration speed of the tonearm is electrically detected and damped by the operation of the servo loop.

Review

The QL-Y5F motor gave a fine set of results - state of the art in fact - and the high torque provided a rapid start up. The arm was geometrically well aligned, and unusually for an automatic it offered variable height and headshell tilt as well - £220 HiFi Choice 1984
