JVC Quartz technology
JVC Super Servo Frequency Generator
Highly Sensitive New Gimbal Support
Quick Start and Quick Stop
The QL-5 has all that's needed for your musical enjoyment including, of course JVC Quartz servo. It's the "no-frills" model in our lineup of Quartz Turntables, and its balanced electrical and mechanical construction makes it a particularly good buy.
JVC Technical Knowhow
To produce expensive state-of-the-art. Equipment is not our only virtue, our knowhow accumulated during a half century of work, permits us to use the best of electronics and machining technique to offer reasonably priced equipment for serious audiophiles JVC Quartz Turntable are no exception. In the medium-priced QL-5 for instance we;ve designed a special C-MOS IC which incorporates all necessary circuits for the servo system. This configuration not only simplifies the circuit-board layout but improves overall dependability.
jVC Quartz and Super Servo FG
With its simplified circuitry and mechanisms, none of the JVC Quartz Technology has been omitted from the QL-5. the precision Quartz oscillator, responsive servo system, JVC Super Servo Frequency Generator, accurate direct drive DC servo motor, etc., are all part of this attractive and supremely reliable turntable package. All superb basic parameters are all included.
Heavyweight Platter
To absorb all miniscule vibrations, the platter must be heavy and accurately concentric. The dynamically balanced one used on the QL-5 is heavy weighing 2 kg (4,4 lbs) rubber mat included. Wow and flutter is thus virtually eliminated, while speed accuracy is maintained against suddenly increased loads. Among other QL-5 features are the Quick Stop, New Gimbal Support, newly designed One-Row Strobe, Oil-Damped Cueing, solid cabinet, and JVC height-adjustable, Dome isolating Suspension.
