Conventional analogue turntables have problems with degradation in sound quality caused by factors such as minute speed vibration during rotation and rotation irregularity called “cogging.” In the SL-1200G, the use of a newly developed coreless direct-drive motor with no iron core eliminates cogging. Also, the twin-rotor construction reduces the bearing load while maintaining high torque and also reduces minute vibration during rotation. These factors enable reproduction of the warm, exquisitely detailed sound etched on analogue records.
The application of motor control technology developed for Blu-ray devices and switching the drive mode depending on the operational status of the motor achieve a high-starting torque and high-speed stability. When the weight distribution of the turntable is uneven, excess vibration or noise occurs during rotation, which causes degradation in sound quality. Therefore, the balance of the turntable is adjusted at the factory by using specialized high-precision balance adjustment equipment for each and every item after the turntable is assembled. Turntables that have undergone adjustment are labelled with a sticker reading “BALANCED” to indicate that adjustment has been done.
The tonearm employs lightweight magnesium which has a high damping effect, with cold drawing improving the characteristics of the material and achieving the high-precision required. In addition, high initial-motion sensitivity is attained by employing the traditional Technics gimbal suspension construction with horizontal rotation axis and the vertical rotation axis intersecting at a single central point, as well as high-precision bearings using a cut-processed housing.
A hairline-processed, 10-mm-thick top panel of immaculate aluminium has been added to the previous three-layered construction of aluminium die-cast, BMC, and heavyweight-class rubber on the SL-1200MK5. This four-layered construction combines high rigidity with a high-quality finish and feel.

Some speculated the move was caused by worn tooling or that production costs had soared or that the market was saturated with used SL-1200s or that with D.J.s “going digital” the market was collapsing. Whatever the reason or reasons, it marked the end of an era that even vinyl haters recognized as remarkable.
Then, at C.E.S. 2016 much to the delight of turntablists world-wide, Technics announced a return to the turntable market with a brand new SL-1200 aimed not at D.J.s but at audiophiles.
There were two “Grand Class” models: the 1200G and the limited to 1200 numbered units 1200GAE edition (long since sold out).
