About the WTB 312

The Acoustic Solid WTB 312 is a premium turntable designed with a sandwich construction chassis made of aluminum and stainless steel with plastodem sound insulation and special dampers for vibration control. It features a heavy solid aluminum platter weighing approximately 6 to 8 kg (sources vary slightly), CNC precision turned and hand polished, with a thickness around 40-60 mm depending on model variations. The drive system uses a Berger Lahr synchronous motor with a belt or string drive and nylon silicone compound belts, controlled by microprocessor electronics for precise speed stability and fine adjustment. The turntable supports convenient speed changes between 33.3 and 45 rpm with fine adjustment possible at any time. The bearing assembly includes a ground stainless steel axle, cast liner, and cast bearing base with Teflon disks and a polished ceramic ball for resonance optimization. The platter mat is made of genuine leather, often with an additional plexiglass pad. The unit weighs around 20-21 kg without the tonearm and measures approximately 500mm width, 390mm depth, and 180mm height with tonearm. Power supply is typically 240V with switching power supply and IEC connector. The WTB 312 is often paired with high-quality tonearms such as the WTB-213 or WTB-370. Synchronization accuracy is measured at about 0.08% using Ortofon measuring equipment. This turntable is highly regarded for its mechanical precision, build quality, and ability to deliver detailed, stable, and natural sound reproduction.
