The Technics Limited Edition Direct Drive Turntable System SL 1210GAE offers several exclusive features and specifications. First, the design uses an lll-black color scheme - making it a thing of beauty. The SL-1210GAE's 10-mm-thick aluminum top panel sports a meticulously anodized black brushed hairline finish. In addition, the operation buttons and tonearm also employ a high quality black finish that results in a uniform, premium appearance.
The SL-1210GAE is wholly made in Japan by skilled artisans' hands, with a significant level of hand-made processes to ensure the highest quality possible. The top panel features a special badge, inscribed with the unique serial number to signify that it is a 55th anniversary model.
The specially developed zinc insulator features αGEL, a soft gel-like material with excellent shock absorbing properties which is also used on the highly acclaimed, 'flagship' SL-1000R reference turntable ((a trademark of Taica Corporation registered in Japan and/or other countries). The high-density zinc die-cast housing offers superb vibration damping characteristics and excellent long-term reliability. The new insulator effectively isolates the turntable from external vibrations, ensuring completely undisturbed music reproduction while preserving every fine nuance and detail within the musical signal.
Turning off the strobe light allows the listener to concentrate more effectively on the music, especially in a dimmed environment.
The Technics SL-1210GAE features a coreless Direct Drive Motor. Conventional analog 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-1210GAE, the use of a 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 achieves a high starting torque and high-speed stability for optimum playback.
The turntable features a three-layered construction with a rigidly combined brass top-plate, an aluminum die cast core platter and a solid rubber coating covering its entire rear surface to eliminate unwanted resonance, thereby achieving overall superior rigidity and vibration damping. This delivers smooth rotational stability and high 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.
When the weight distribution of the turntable is uneven, excess vibration or noise occurs during rotation, which causes degradation in sound quality. To counteract this, 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 individual 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 the 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.
The use of brass-milled and gold-plated phono terminals and ground terminals prevents degradation in sound quality while enabling the easy attaching and detaching of cables. Also the use of metal shielding construction inside the case reduces the effects of external noise.
A hairline-processed, 10-mm-thick black top panel of immaculate aluminum is added to a three-layered construction of aluminum diecast, BMC (Bulk Moulding Compound), and heavyweight-class rubber. This four-layered construction combines high rigidity necessary for superb vibration damping with a superior solid build and a luxurious finish and feel.
