The SME Model 15 Mk2 is a precision-engineered high-end turntable designed around a rigid, high-mass platform, advanced mechanical isolation and accurate electronic speed control. This configuration is supplied with the acclaimed SME Series Vᵢ tonearm, providing a highly precise analogue front end for demanding vinyl playback.
The Model 15 Mk2 is built around a substantial CNC-machined aluminium chassis and sub-chassis. The rigid construction provides a stable platform for the precision bearing, platter and tonearm, while the isolated sub-chassis is designed to control unwanted mechanical energy.

| Construction | High-Mass / Rigid |
| Suspension | Isolated Sub-Chassis System |
The Model 15 Mk2 incorporates a substantial precision-machined platter supported by a close-tolerance main bearing. The platter uses an iso-damped construction with a diamond-turned playing surface to provide a stable interface between the record and the rotating platform.

| Platter Surface | Iso-Damped / Diamond-Turned |
| Main Bearing | Precision Close-Tolerance Bearing |
| Spindle | High-Chrome Tool Steel |
| Record Clamp | Reflex-Type Screw-Down Clamp |
The supplied SME Series Vᵢ tonearm is engineered for accurate cartridge alignment, controlled resonance and precise tracking. Its rigid construction and carefully controlled bearing system allow the cartridge to follow the record groove with high mechanical stability.

| Motor | Bi-Phase AC Synchronous Motor |
| Motor Control | DSP-Based Electronic Speed Control |
| Playback Speeds | 33⅓ RPM / 45 RPM |
| Speed Adjustment | Fine Adjustment in ±0.01% Increments |
The suspended sub-chassis works with the turntable's isolation system to reduce the transfer of external mechanical energy. Four mechanically de-coupled adjustable feet provide accurate levelling and a controlled connection with the supporting surface.
| Feet | 4 Fully Adjustable |
|---|---|
| Foot System | Mechanically De-Coupled |
| Isolation | Integrated Mechanical Isolation |
| Levelling | Fully Adjustable |
The separate Speed Control Unit provides electronic management of platter speed. It offers dedicated settings for 33⅓ and 45 RPM together with fine adjustment for precise pitch control.
