It is also compatible with a wide range of turntables using 110V synchronous motors.\u003c\/p\u003e\n\u003cp\u003eMany turntables do not run accurately at 33.33 rpm, often drifting significantly. The Zeus controller corrects these inconsistencies, delivering tighter timing, improved rhythm, and a more stable soundstage, enhancing overall musical performance.\u003c\/p\u003e\n\u003cp\u003eThe unit features an optical platter speed sensor and OLED display, providing real-time feedback and precise control. Using microprocessor-based control and advanced sine wave frequency synthesis, it ensures highly accurate motor drive and stable platter rotation.\u003c\/p\u003e\n\u003cp\u003eDesigned, assembled, and tested in the UK, the Zeus controller is fully CE and UKCA approved. It includes automatic speed calibration and PID-controlled feedback to compensate for wear in belts, pulleys, bearings, motors, and stylus drag.\u003c\/p\u003e\n\u003cp\u003eThe controller is designed to fit directly onto the original Linn Valhalla cross brace mounting and is compatible with upgrades such as the Linn Karousel bearing. It can also be installed in other turntables such as the Linn Axis (soldering required).\u003c\/p\u003e\n\u003cp\u003eKey Features:\u003c\/p\u003e\n\u003cp\u003e• High-precision turntable speed controller\u003cbr\u003e• Replacement for Linn Valhalla, Hercules, Lingo, Mose and similar\u003cbr\u003e• Compatible with 110V synchronous motor turntables\u003cbr\u003e• Optical platter speed sensor with OLED display\u003cbr\u003e• Microprocessor-controlled operation\u003cbr\u003e• Electronic switching between 33.3 rpm and 45 rpm\u003cbr\u003e• Automatic speed calibration\u003cbr\u003e• Designed, assembled, and tested in the UK\u003cbr\u003e• CE and UKCA approved\u003cbr\u003e• Fits original Linn Valhalla mounting\u003cbr\u003e• Compatible with Linn Karousel bearing\u003cbr\u003e• Installation service and DIY options available\u003c\/p\u003e\n\u003cp\u003eTechnical Highlights:\u003c\/p\u003e\n\u003cp\u003e• Frequency accuracy controlled to 0.001 Hz\u003cbr\u003e• Platter speed accuracy within ±0.003 rpm\u003cbr\u003e• PID feedback control for stable speed regulation\u003cbr\u003e• Compensation for mechanical wear and stylus drag\u003cbr\u003e• Adjustable motor parameters via USB serial interface\u003cbr\u003e• EEPROM storage for saved configuration settings\u003cbr\u003e• Super quiet mode to reduce motor vibration\u003cbr\u003e• Configurable auto start and sleep functions\u003cbr\u003e• OLED display with speed and WOW indication\u003cbr\u003e• Stylus and bearing runtime tracking\u003cbr\u003e• Class A motor drive circuitry with reduced heat output\u003c\/p\u003e\n\u003cp\u003eSpecification:\u003c\/p\u003e\n\u003cp\u003e• Motor Compatibility:\u003cbr\u003e– 110V synchronous motors (Linn, Premotec, Philips, Airpax etc)\u003cbr\u003e• Frequency Output: 50 Hz or 67.5 Hz\u003cbr\u003e• Frequency Accuracy: 0.001 Hz\u003cbr\u003e• Speed Accuracy: ±0.003 rpm\u003cbr\u003e• Power Supply: 110V – 230V, 50\/60 Hz\u003cbr\u003e• Mounting: Linn Valhalla cross brace compatible\u003c\/p\u003e\n\u003cp\u003eWhat’s Included:\u003c\/p\u003e\n\u003cp\u003e• Zeus Turntable Speed Controller\u003cbr\u003e• Optical platter sensor\u003cbr\u003e• OLED display unit\u003cbr\u003e• Documentation\u003c\/p\u003e\n\u003cp\u003eNote:\u003c\/p\u003e\n\u003cp\u003eIncludes a 30-day trial period.
