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.

High precision arm
The plane is made of three layers. The body itself is cast from aluminum.
It is insulated with a high-density rubber on the inner side, and a brass plate on the upper side.
The turntable is perfectly balanced, does not resonate and has enough mass to ensure inertia in movement.
The turntable is manually adjusted and balanced in the laboratory
Coreless Direct Drive Motor
High-precision Motor Control Technology
The application of motor control technology developed for Blu-ray devices and switching the drive mode depending on the operational status of the motor achieves a high-starting torque and high-speed stability.
Three-layered Turntable Platter
The turntable has a three-layer construction with a rigidly combined brass and aluminum die-cast platter. With a deadening rubber covering its entire rear surface to eliminate unnecessary resonance, thereby achieving high rigidity and vibration damping. This delivers smooth rotational stability and inertial mass surpassing the SP-10MK2, the direct-drive turntable standard used by broadcast stations worldwide, as well as having more than twice the inertial mass of the SL-1200MK5.
High-level Balance Adjustment
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 labeled 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 achieved 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.
Four-layer Cabinet Construction
A hairline-processed, 10-mm-thick top panel of immaculate aluminum has been added to the previous three-layered construction of aluminum 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.
