JVC QL-F61 turntable

Quartz Locked Fully-Automatic Direct-Drive Turntable.

Advanced Tonearm Design to Complement Quartz Drive System

The QL-F61 is more than just sleek, slim and solid; it's jampacked with futuristic JVC technology. One example is the advanced Double Servo Quartz control to adjust platter speed with unerring accuracy. Another is the coreless DC motor that the servo control operates; iy's brushless, coreless and cog-free. The arm is of the low-mass straight line type for better tracking. For convenience's sake, the turntable is full automatic from cue-in to end of play and shut-off.

 

Smooth platter rotation is assured by the JVC-made coreless DC motor and Double Servo Quartz control

Our ideally matched motor and servo system achieve unimaginably low wow and flutter of 0,025% (WRMS). Signal-to-Noise Ratio is better than 75 dB (DIN-B). Never again will varying pitch, however infinitesimal, mat your musical reproduction, even if the record is of the latest direct-to-disc or digital variety.

 

Low-mass straight tonearm for lighter, better tracking.

The conventional high mass tonearm cartridge combination can produce harmonic distortion on the order of 10% when tracking even a barely visible record warp. But the tonearm of the QL-F61 reduces distortion to practically nil even on moderate wsarps because of its low-mass design. Low mass means a higher resonance frequency (slightly above the warp frequency), a reduced resonance peak, and higher sensitivity. The straight contour of the arm ends spurious movement of the arm due to dynamic torsion.

 

Up-front controls for your convenience

Gone is the cluttered lok that keps you away from the controls when the dust cover is closed. Along the front edge of the QL-F61 are all the operation buttons - "touch" buttons - for record speed, pitch control, quartz on/off, repeat, record size, start/stop and  even arm cueing.

Fully automatic operation with repeat.

Operation is completely automatic from beginning of play to end; there's never any need to touch the tonearm. This is a definite plus when there are kids around who may not be particularly adept at handling the tonearm. Records and stylus are protected. When you're in the mood, switch on the repeat function and listen to the entire side of a record over and over.
