Panasonic to Unveil
Technics Direct Drive
Analog Turntable
Prototype at IFA with an
Eye on 2016 Commercial
Launch
Osaka, Japan - Panasonic Corporation announced that it will exhibit a direct drive1 analog turntable prototype equipped with a
newly developed direct drive motor at the IFA 20152 trade fair to be held in Berlin from September 4 to 9, 2015. Panasonic is
accelerating further development of this technology with a view to market launch in 2016 under the Technics hi-fi audio brand.
In conventional analog turntables, sound quality degradation caused by tiny vibrations of the motor and rotational speed
fluctuations has been a major challenge. To overcome this challenge and assure smooth, highly-stable rotation, Panasonic has
developed a new direct drive motor and redesigned high-precision motor control technology. This makes it possible to reproduce
the warm sound and subtle nuances of musical expression engraved in the analog record grooves.
The newly-developed direct drive motor has the following features:
•Coreless stator design that eliminates cogging3
•Twin rotors that reduce bearing load and minimize tiny rotational fluctuations (wow & flutter), while maintaining high torque
•Oil impregnated high-precision bearings that minimize unwanted vibrations during rotation
The redesigned direct drive motor control technology involves the following:
•Spindle motor control technology4 that switches the stator winding drive mode according to operat ing conditions to provide
both high starting torque and high rotational stability
•Adaptive rotational control technology5 that achieves optimized compensation according to precision rotational position
detection and load fluctuation factors Development background and goals.
Demand for analog turntables has been on the rise in recent years as music aficionados once again find the value in the sound of
analog records, mainly in the North American, European and Japanese markets.
Panasonic put on sale the world's first direct drive analog turntable6 in 1970 under the Technics brand. This was followed by the
SL-1200 series7, which earned the brand critical acclaim for its outstanding sound quality and reliability, not only from
audiophiles, but also dance and music clubs, studios, broadcasters and other commercial users around the globe. Technics has
become synonymous with "turntable" as the first choice of club DJs, whose support has remained strong and who are awaiting a
new model to come out.
This September marks the beginning of the second year since the Technics brand's rebirth in 2014 and the 50th year since its
birth8.
To celebrate this opportunity, Panasonic has developed an analog turntable that combines its heritage of "emotive acoustic
technology" and advanced digital technology to provide new technological synergies. To deliver greater satisfaction to customers
worldwide, the company will continue to refine its technology, including the prototype on display at IFA, which draws visitors
who demand the highest sound quality and are well-versed in audio equipment.
In a direct-drive turntable, the turntable platter spindle is, in fact, the shaft of an ultra-slow servo-controlled motor.
IFA 2015 consumer electronics exhibition held in Berlin, Germany, Friday the 4th through Wednesday the 9th of September.
Cogging is motor speed ripple arising from the rotational angle dependence of magnetic attraction between rotor magnets and
stator windings.
Minimized cogging assures smooth rotation and enables precision servo control.
Technology that switches stator winding drive mode between high-torque startup and normal platter speed, which requires
accurate rotational speed control.
This uses an encoder to detect rotational position at high speed, together with a compensation table based on load fluctuation
factors on bearings and other variables, thereby enabling adaptive individually-optimized control.
The world's first direct drive turntable to be marketed. Model number SP-10. Technics direct drive technology successfully
overcame the problems of conventional drive systems (belt-drive and rim-drive), such as rubber deterioration causing rotational
speed fluctuation and speed deviation, as well as noise caused by belt vibration. As a result, direct drive became the new
standard for analog phono reproduction.
The SL-1200 series evolved through ten models (listed below) during the hi-fi audio boom, beginning in 1972 with the SL-1200
and continuing through 2007 with the SL-1200MK6. Over a period of 35 years, it has continued to be a long-run hit, evolving to
transcend the role of "record player" and gain unshakable renown and prestige for performance that satisfies the senses and
meets the needs of demanding professionals, particularly DJs who use it as a musical instrument.
