Kuzma - Stabi Ref 2 Digital AC Power Supply/Speed Control
The Kuzma Stabi Ref 2 Digital AC Power Supply / Speed Control is a dedicated external controller designed to provide precise, stable motor drive for Kuzma’s twin-motor Reference-series turntable platform. Rather than relying on raw wall current, it generates a carefully controlled AC signal for both motors, helping the turntable maintain consistent platter rotation with reduced vibration and improved long-term speed stability. This design supports the kind of pitch accuracy and mechanical refinement demanded by serious analog playback systems.
Kuzma’s published documentation describes a dual sine-wave output controlled by a sophisticated computer-based program, allowing very smooth waveform generation and very fine speed selection. Each playback speed can be independently selected, finely adjusted, and stored in memory, making it easier to dial in accurate 33 and 45 RPM operation. In the Stabi Reference 2 system, the outboard supply feeds both AC motors with precisely generated sine waves, amplified to help optimize drive consistency and minimize noise introduced by motor operation.
Built as a purpose-designed companion for Kuzma’s high-mass belt-drive architecture, the Digital AC Power Supply / Speed Control is an important part of the Stabi Ref 2’s performance envelope. It helps the turntable achieve the speed precision, low mechanical interference, and operational flexibility expected from a reference-grade analog front end, while giving users convenient external control over playback speed and calibration.
