GRAMOFON JVC QL - Y5F + WKLADKA JVC-X1
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.
