High-precision motor controller and power supply for turntables.
Compatible with Transrotor turntables · Made to order
Isostase is the system developed by Olydyne for high-end turntables: a controller and its dedicated motor power supply. Real-time speed regulation, automatic motor balancing, and component wear tracking: every function serves one goal, stable and precise playback, revolution after revolution.
Isostase is currently developed and tested exclusively for Transrotor turntables.
Isostase's power supply block is designed specifically to drive one or two Transrotor turntable motors with precision and stability, for long-term reliability.
Designed as an alternative to the original power supply on high-end Transrotor turntables, it adds regulation, optimization, and diagnostic functions not found on standard power supplies.
An optical sensor measures rotation on every platter revolution and corrects speed continuously, for constant pitch stability.
Automatically adjusts the drive level between motors (power balance), validated with a stability measurement to confirm the change actually helps.
Automatically finds and aligns the electrical timing between motors (angular synchronization), for the smoothest possible rotation on dual-motor setups.
Stylus and platter wear tracking, with management of multiple phono cartridges in memory.
Multi-sensor monitoring (processor, power supply heatsinks) with progressive power reduction under heat, protecting the power electronics.
A dedicated cycle for record cleaning, and a reduced-amplitude playback mode for quieter operation.
Clear graphical interface, available in French, English, German, Spanish, Portuguese, and Italian.
Hardware and software watchdog monitoring for reliable long-term operation.
Continuous logging of key parameters (temperatures, currents, speed, voltages) and usage statistics (run hours, protection events) on the built-in SD card.
Harmonic distortion and motor vibration signature tests, with results archived for long-term trend tracking.
Every automatic decision made by the system (thresholds, triggers, outcomes) is logged for transparent diagnostics.
The turntable stops itself after an adjustable duration, with speed-specific limits to protect the record and the motor.
Switching to 78 RPM is handled electronically, with no need to move the belt to a different pulley step.
A real-time estimate of speed stability, shown directly on the controller — a useful diagnostic indicator, not intended to replace a professionally calibrated measurement instrument.
Speed accuracy calibrated against a quartz reference, with automatic detection and correction of long-term drift.
Acceleration and deceleration ramps automatically adjust to the installed platter's weight, protecting the motor and preventing belt slippage (and its premature wear), regardless of the Transrotor model.
Fine speed adjustment, shown as a percentage and in semitones, stored separately for each speed and each user profile.
A multi-step break-in cycle for new components, with on-screen progress tracking.
Runs the motor before listening, adjustable duration — the classic audiophile ritual, automated.
The motors are driven by genuine high-fidelity audio digital-to-analog converters, for an exceptionally clean drive waveform and less parasitic vibration than a generic motor driver chip.
Isostase's power supply is designed as an alternative to the original motor power supply on high-end Transrotor turntables, adding regulation, phase optimization, and diagnostic functions not found on a standard power supply.
Isostase, controller and power supply included, is currently developed and tested for single and dual-motor Transrotor turntables. Model-specific compatibility will be detailed as development progresses.
Isostase combines real-time speed regulation via optical sensor, automatic motor phase optimization, wear tracking, and SD card data logging — functions absent from original or generic power supplies.
No. Isostase is a product developed by Maptuner LDA under the Olydyne brand, compatible with Transrotor turntables, with no affiliation, partnership, or official endorsement from the Transrotor brand.
