Dual CS5000 (1987–1990)
A semi-automatic belt-drive turntable with quartz speed control and OPS tonearm system, built for precision and low wow flutter.
Overview
The Dual CS5000 is a semi-automatic turntable made by Dual, Gebr. Steidinger in St. Georgen/Schwarzwald. Produced from 1987 to 1990, it features a belt drive system powered by a microprocessor-based quartz-controlled DC motor, ensuring stable speed across 33, 45, and 78 rpm. Designed with high mechanical accuracy, it includes an auto lift-up mechanism that uses non-contact detection to raise the tonearm at the end of a record without affecting the stylus. The unit was originally priced at ¥115,000 around 1988.

Design
The CS5000 uses a belt drive system with a microprocessor-based quartz control DC motor and speed detection for precise rotation. It features a die-cast platter with a 1.5 kg vibration tamping structure and anti-resonance coating to enhance sound clarity. The tonearm employs a gyroscope, gimbal, and four-bearing point contact support system with precision polishing, and operates on a dynamic balance system using a high-precision spring for accurate tracking force. Equipped with OPS (Optimum Pivot System), the tonearm's bearing point aligns with the record surface height, minimizing wow flutter from warps or vibration. The head shell includes a VTA adjustment mechanism allowing ±5 degrees of vertical tracking angle change via a knob without altering arm height. Speed switching is electronic, and the cabinet uses a floating chassis to isolate the turntable and arm from external vibrations.
Context
The Dual CS5000 was positioned as a midmarket turntable, representing a step up from entry-level Dual models. It was noted as one of the brand's final high-end offerings, combining advanced features like quartz lock speed control and OPS to deliver performance suitable for critical listening.
Market
Owners report the CS5000 as a durable unit, though some note common issues such as failing power supply capacitors and grounding-related hum. The tonearm is designed for low-mass cartridges, making it a good match for models like the Ortofon OM series. Units have sold in recent years for prices ranging from $200 to $700, depending on condition, with some listed as high as $1,250. A service manual is available through the VinylEngine forum library.
