The SME Model 30/12 Mk2 is a reference-level precision turntable designed around exceptional mass, rigidity, vibration control and rotational accuracy. It combines a CNC-machined aluminium chassis and suspended sub-chassis with advanced fluid damping, a precision main bearing and a large 330 mm platter. This configuration is supplied with the flagship SME Series V-12 tonearm, making it a complete high-end analogue playback platform.
The Model 30/12 Mk2 is built from premium-grade aluminium billet using precision CNC machining. The main chassis and sub-chassis are designed to resist low-frequency flexing, while extensional damping helps attenuate high-frequency resonance. The larger 30/12 platform provides additional mass and rigidity compared with the standard Model 30.
| Chassis Material | Premium-Grade CNC-Machined Aluminium Billet |
|---|---|
| Construction | Heavy-Mass / Precision Machined |
| Sub-Chassis | Suspended Precision-Machined Aluminium |
| Damping | Extensional Acoustic Damping |
The suspended sub-chassis carries the main bearing, platter and tonearm while isolating them from the main chassis. It is supported by 60 purpose-made suspension rings. Four suspension-column fluid dampers control sub-chassis movement and help prevent unwanted overshoot and resonance.
| Suspension Type | Suspended Sub-Chassis |
|---|---|
| Suspension Rings | 60 Purpose-Made Rings |
| Damping | Four Suspension-Column Fluid Dampers |
| Isolation Feet | 4 Fully Adjustable Mechanically De-Coupled Feet |
The Model 30/12 Mk2 uses a substantial 330 mm precision-machined aluminium platter weighing 7.5 kg. The platter is extensionally damped and incorporates an Iso-Damp surface with a diamond-turned finish. The main spindle is precision-machined from high-chrome tool steel and runs in a sealed bearing housing with individually fitted sintered-bronze bearings.

| Type | 12-Inch Precision Tonearm |
| Internal Wiring | Crystal Cable |
| Configuration | Factory-Fitted to Model 30/12 Mk2 |
The turntable uses a custom bi-phase AC synchronous motor controlled by a dedicated Speed Control Unit. The motor is designed for quiet operation and precise rotational stability.
| Drive Method | Belt Drive |
|---|---|
| Motor | Custom Bi-Phase AC Synchronous Motor |
| Motor Control | DSP-Based Electronic Speed Control |
| Playback Speeds | 33⅓ RPM / 45 RPM |
| Speed Memory | Independent Settings for Each Speed |
| Fine Adjustment | ±0.01% of Selected Speed |
The dedicated Speed Control Unit uses a DSP engine to generate two independent mathematical sine waves controlling the motor's frequency, phase relationship and amplitude. Independent memory settings are available for 33⅓ and 45 RPM.
| Control System | Dedicated DSP Engine |
|---|---|
| Speed Selection | 33⅓ RPM / 45 RPM |
| Memory | Independent Settings |
| Fine Speed Adjustment | ±0.01% |
| Housing | CNC-Machined Billet Polymer Resin with Aluminium Fascia |
The mains transformer is housed in a separate external Power Unit. This keeps the transformer physically separated from the Speed Control Unit and, importantly, away from the turntable's sensitive audio signal cables.
