Transrotor turntables

An alternative to the original motor power supply

On a belt-drive turntable, speed stability depends directly on the quality of the signal driving the motor. Isostase replaces the original motor power supply of Transrotor turntables (the entire Konstant range) with a dedicated generator: a sine wave generated digitally by CD-quality audio DACs, with frequency, amplitude and phase each adjusted independently, a quartz frequency reference, and closed-loop regulation thanks to an optical sensor that measures the platter's actual rotation.

Isostase is compatible with the Transrotor Zet, Fat Bob, Rondino, Massimo, Leonardo, Dark Star and many more: see the full list of compatible turntables.

The brand

About Olydyne

Olydyne designs high-end electronic systems for the world of the turntable. The brand is built on precision motor control, for stable rotation and real-time diagnostics.

Every Olydyne product follows the same standard: rigorous electronics, built-in measurement and diagnostics rather than guesswork, and attention to the details that make a difference when listening.

How Olydyne began

Olydyne's story begins with a Transrotor turntable. Its French founder has always been passionate about audio, starting by modifying and upgrading existing equipment before going on to design original audio components. Owning a Transrotor revealed exceptional engineering and an original motor power supply of excellent quality, yet one that simply did what a power supply is expected to do: power the motor.

To an electronics engineer, that was an invitation. Why not go further: measure the platter's actual speed and correct it continuously, optimise the motor phases, track the turntable's condition, provide diagnostics? Isostase, the most ambitious project undertaken so far, grew out of that desire, and with it the whole Olydyne brand.

Isostase is not a criticism of Transrotor turntables but a tribute: a way to build on what they already do remarkably well, with electronics that do more.

Olydyne products will be made to order only. The brand is developed by Maptuner LDA, based in Lisbon, Portugal.
