JVC QL-A2 turntable

JVC Quartz Auto-Return Turntable features:

JVC Quartz technology - Low Wow and Flutter 0,025%

Dependable JVC Super Servo Frequency Generator

JVC Core - Less Direct Drive Motor

Auto-Return Convenience at Attractive Price

 

The QL-A2 delivers the same accuracy and dependability of all JVC Quartz units. In addition to its first-rate specifications of 0,025% wow/flutter (WRMS) and  72 dB Signal-to-Noise Ratio (DIN-B), it has an auto-return mechanism for added convenience. Remember, only JVC's advanced techniques can bring such low-priced perfection to your stereo performance.

 

jVC Quartz Technology

The basic circuit configuration of the QL-A2 is the same as the one used in the QL-F4. an accurate Quartz oscillator, JVC's Super Servo Frequency Generator and "no-cogging" Core-Less DC Servomotor are all included in the QL-A2. moreover, JVC's simplified circuits and advanced production techniques are abundantly used in its production, leading to dramatically improved stability and accuracy.

New One-Row Strobe

With the One-Row Strobe used with the QL-A2, you can visually confirm speed accuracy. Since the LED flashes on and off, synchronized with the frequency of the Quartz, the strobe pattern is always sharp and clean. And since the frequency is changed with the speed, only one row of calibration dots is necessary for communicating the information for both 45 and 33-⅓ rpm.

 

 

Dependable Auto-Return /Shut-Off

As you move the tonearm toward the record, the platter starts to rotate in our "Quick Play Function". When the leadout groove of the record is played, the arm automatically lifts itself up, returns to its rest and shuts the power off in the "Auto-Return/Shut-Off Function". Like the QL-F4, the QL-A2 can be operated as if originally designed for manual operation since its arm may be moved manually anytime. Other features include a Reject Lever that returns the arm during play and a Cue Lever to lift the arm up and down. The tonearm features the Angular Contact Bearing Oil-Damped Cueing, insulated arm/weight interface and more.
