Way back in 1970 Technics launched the world’s first direct - drive turntable the SP-10. In doing so they created a new era in audio. The new drive system eliminated the vibration and rotation irregularity caused by the more traditional belt - drive system. Even though the SP-10 was designed for consumer use, it was quickly taken on by broadcasting companies around the world.

The success of the SP-10 was followed in 1972 by the SL-1200 series of direct - drive turntables which resulted in establishing a reputation for stable rotation and reliability. As they say “the rest is history”. The SL1200 series was in production for nearly 40 year with about 3.4 million units being sold world wide. It found great favour with DJ’s as well as audiophiles and was subsequently copied by many other manufacturers but never quite catching the following of a real Technics SL1200/1210.

After a period away from the audio market, the Technics brand was relaunched by it’s parent company Panasonic. Along with a range of electronics and loudspeakers Technics have relaunched a series of SL1200 turntables for the 21st Century. The relaunch required the engineers to start from scratch as all the original holdings and manufacturing equipment were beyond repair - the only one to have survived the 40 years of production was the moulding for the acrylic cover with it’s signature dome over the tonearm mounting.

After a very successful Limited Edition run of 1200 - 50th Anniversary SL1200’s - which literally sold out as soon as the news of them was released - 3 models are now on the range.

Grand Class SL-1200GR:

Leading-edge Technologies Deliver Rich, Robust, Analogue Music in a New Standard Direct-Drive Turntable System.

Price: £1299

Supplied without a cartridge.


Launched in 2016, the SL-1200G combined Technics‘ traditional analogue technology and advanced digital technology. Its outstanding performance literally rocked the hi-fi market and redefined the reference for direct-drive turntables.
Parts from the SL-1200G were newly developed to create the SL-1200GR, such as the coreless direct-drive motor and precise motor control technology, high-rigidity platter and high-sensitivity tonearm. This ensures audio enthusiasts using the SL-1200GR can enjoy music with the rich, robust sound of analogue records.
Coreless Direct-Drive Motor Achieving Stable Rotation
Unlike belt-drive and other systems, direct-drive systems rotate the motor at low speed and directly drive the platter. This concept provides numerous advantages, such as the almost complete absence of degradation in S/N ratio due to motor vibration and deceleration mechanisms, as well as high reliability over a long period of time because of not requiring parts replacement.
In 2016, Technics developed the twin-rotor, surface-facing, coreless direct-drive motor with rotor magnets placed on both sides, eliminating the rotation irregularity of the motor, referred to as "cogging," which was a unique issue for direct-drive systems. This motor was adopted for the SL-1200G, which once again drew a significant response in the hi-fi market. The SL-1200GR inherits the same design philosophy with the new development of a single-rotor, surface-facing, coreless direct-drive motor, resulting in the elimination of cogging.
The SL-1200GR’s rotation control, which verifies and corrects the precision of the motor, uses the latest motor control technology cultivated in the development of Blu-ray devices, just as that used by the SL-1200G. In addition, the electrical circuitry has been tuned to ensure the newly developed motor of the SL-1200GR achieves maximum performance.
Turntable Platter —Pursuing Rigidity and Vibration Damping Characteristics
The platter achieves high-rigidity and vibration-damping characteristics by using a two-layer construction with deadening rubber applied to the entire rear surface of the aluminum die-cast. This eliminates the unnecessary resonance that is otherwise relayed to the record, thereby producing clear sound.
To increase the inertial mass and to reduce vibration, the shape of the aluminum die-cast portion was optimised by simulation. At 2.5kg (including the rubber mat), the SL-1200GR platter is 0.8kg heavier than that of the previous SL-1200MK5. Also, the back surface of the platter features strengthening ribs to improve rigidity. Increasing the surface area of contact with the deadening rubber achieves damping characteristics that are more than twice as good as those of the SL-1200MK5.
Tonearm Achieving High Initial-Motion Sensitivity
The tonearm tracks the rotation of the record and enables reading with high precision. The tonearm inherited by Technics is the traditionally used static-balance universal S-shaped tonearm, employing an aluminum pipe with excellent light weight and rigidity for the material of the tonearm pipe.
With its gimbal suspension construction, the tonearm bearing section of the SL-1200GR uses a cut-processed housing that employs high-precision bearings, as in the SL-1200G. The high initial-motion sensitivity of 5mg or less is achieved through manual assembly and adjustment by skilled Japanese artisans. This enables the grooves etched into the records to be accurately traced.
Gold-plated phono terminals and ground terminals for detachable cables are provided below the tonearm, so a wide variety of cables can be selected. Also, the use of metal shielding construction inside the case reduces the effects of external noise.
High-rigidity Body and High-damping Silicon Insulators for Beautiful Sound and Isolation from Various Vibrations
The SL-1200GR ensures high-rigidity by using a body with a two-layered construction solidly unifying the BMC and the aluminum die-cast chassis.
For the insulators supporting the body, as with the SL-1200G, the SL-1200GR uses special silicon rubber that ensures both high vibration damping characteristics and long-term reliability. Vibration in the horizontal direction is absorbed by reinforcement with cylindrical tubes using microcell polymers. While inheriting the technology of the SL-1200G, the insulators have been modified to specifically suit the characteristics of the SL-1200GR.

Features:

A Coreless Direct Drive Motor
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 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 achieve a high-starting torque and high-speed stability.


Three-layered Turntable Platter
The turntable has a three-layered construction with a rigidly combined brass and aluminium 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 labelled with a sticker reading "BALANCED" to indicate that adjustment has been done.

Exhaustive measurement are performed to examine whether the surface deflection of the platter is within limits

High-sensitive Tonearm
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.

Supplied auxiliary weights support a wide variety of cartridges

Four-layered Cabinet Construction
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.

High-quality Terminals
The use of brass-milled, gold-plated phono terminals and ground terminals prevent 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.
