High-precision motor control for maximum speed stability

The speed control monitors the constancy of the rotation and readjusts it if necessary. This uses the latest control technologies, which are also used in Panasonic Blu-ray players and the SL-1200G. Sine waveforms stored in ROM drive the motor at a constant speed.

This makes the rotation more uniform than with a simple sine wave generator with an external coil, as used in the SL-1200MK5. In addition, the electronic circuit design has been further optimized so that the newly developed motor of the SL-1210GR operates under perfect conditions. The starting torque reaches 2.2 kg-cm (0.22Nm) with only a single rotor. The start-up time of 0.7s (up to 33 1/3 rpm) is thus identical to the SL-1200G.

Highly sensitive tone arm

The tonearm scans the grooves of the record with ultimate precision. It uses the statically balanced S-shaped tonearm traditionally used in Technics turntable. The tonearm tube is made of a light and rigid aluminum profile.

The tonearm bearing is gimbaled. Similar to the SL-1200G, the bearing legs consist of high-precision milled parts. The needle bearings for the bearing axles are of the highest precision. Thanks to the highest manufacturing precision, as it is only possible by the skill of experienced special forces, and the fine adjustment of experienced specialists, a sensitivity of less than 5 mg is achieved.

The sampling process of the record thus runs with extreme sensitivity. For a wide range of pickup systems, an auxiliary weight is included in addition to the main counterweight. Thus, a generous selection of pickup systems is possible depending on the music style. (Insertable cartridge weight using the additional counterweight: 10 – 16.4 g, headshell not included).

High-quality connectors guarantee excellent sound and premium appearance

Chassis with high rigidity and vibration-absorbing silicone damping feet for pure sound and good protection against shocks

The die-cast aluminum chassis is firmly bonded to the BMC (Bulk Molding Compound) lower shell. This two-layer caabinet ensures high rigidity. As with the SL-1200G, special silicone rubber is used for the damping feet that support the chassis.

It causes high vibration damping and good long-term resistance. Vibrations in the horizontal direction are absorbed by a cylindrical guide ring made of small-cell polymer.

This process, which originated in the SL-1200G, has been specially adapted to the SL-1210GR. The height of the damping feet is adjusted via threaded screw bolts. This avoids the vibrations that occur when the turntable is placed on a shelf, for example. Perfect horizontal alignment of the platter also ensures maximum mechanical rotational stability without disturbing imbalances.
