A newly developed coreless direct drive motor that achieves stable rotation.

Two-layer platter in pursuit of rigidity and vibration damping characteristics

In order to solve the problem of rotation unevenness called "cogging", which was a problem of direct drive type turntables, we have newly developed a single rotor type coreless direct drive motor that uses a coreless stator that eliminates the core from the coil. ..

Furthermore, by applying the latest control technology cultivated in Blu-ray Disc equipment, stable rotation has been achieved by outputting an accurate sine wave with a microcomputer for constant speed control. The rotor yoke and rotor magnets that make up the motor are fixed to the platter with a two-layer structure. A structure in which the motor and platter are firmly connected is adopted to realize more stable rotation.

The electric circuit is also tuned to maximize the performance of the newly developed motor and platter.

As a result, we have achieved a rotation accuracy that exceeds the SL-1200MK6 *. The rise time is the same 0.7 seconds (at 33 1/3 rotation).

Enhanced high rigidity and vibration resistance. Tough housing structure that supports beautiful sound

The SL-1200GR uses a two-layer structure that firmly integrates the BMC (bulk molding compound) and aluminum die-cast chassis to ensure high rigidity.

In addition to rigidity and vibration resistance, the aluminum die-cast chassis on the surface has a matte coating with a calm texture to enhance the texture.

The insulator that supports the housing and reduces vibration from the outside uses a special silicone rubber that has both high damping characteristics and long-term reliability. It was completed by tuning it exclusively according to the weight of the main body.

In addition, the platter with a two-layer structure in which aluminum die-casting and deadening rubber that eliminates unnecessary resonance are bonded to the entire back surface has an inertial mass of approximately 2.5 kg (including rubber sheet), which is 0.8 kg higher than SL-1200MK6 *. Increased. Furthermore, by pursuing lower vibration and repeating precise simulations, the shape of the aluminum die-cast part is optimized and reinforced ribs are added to increase the rigidity.

As a result, vibration damping characteristics that are more than double that of SL-1200MK6 * have been achieved.

Tone arm pursuing excellent initial sensitivity and tracing performance

The tone arm, which is important for reading the music information engraved on the record with high accuracy, inherits the static balance type of Technics tradition.

A lightweight and highly rigid aluminum pipe is used for the tone arm pipe. High-precision bearings using a machined housing are used for the tone arm bearings of the gimbal suspension structure.

As a result, a high initial sensitivity of 7 mg to 5 mg or less for SL-1200MK6 * has been achieved. Allows accurate tracing of vinyl records. Also, in addition to the standard weight, an auxiliary weight is included. The applicable cartridge mass when using the auxiliary weight is 18.7 to 25.1 g (including the attached head shell), and it can be installed with a wide range of cartridges.

In addition, a detachable AC input terminal and a gold-plated PHONO terminal have been adopted to enable high-purity signal transmission.
