Motor controller - Revelation I

The motor and its control system play a crucial role in vinyl playback. The choice of motor and the method of its drive have a direct impact on the listening experience. Standard solutions on the market could not meet our exacting standards, which led us to develop a proprietary motor control system featuring specialized sensors and custom software. The result is a playback experience of extraordinary quality. Prepare to be amazed.

Sensor

Our high-precision, industrial-grade sensor provides an asymmetric three-point measurement for exceptional accuracy. A low-noise power supply ensures precise readings, while direct speed detection at the platter maintains a constant rotational speed across the entire playback range.

This allows for compensation of the varying drag exerted by the cartridge over the record, ensuring optimal performance at every moment.

Controller

Our controllers feature two processors: one dedicated to control calculations, and a second for reading the highly precise timing signal. We use PID controllers that can be optimized by the user via our app, depending on the motor controller.

Our ultra-precise 16-bit digital-to-analog converter operates on an exceptionally elaborate, low-noise power supply, allowing full utilization of its 65,536 control steps for maximum precision.

Massive chassis

The foundation of outstanding sound is an ultra-stable mechanical design. Our enclosures are engineered accordingly, incorporating innovative chassis technologies.

Our unique third-generation Powerblock technology provides a secure, stabilizing, and vibration-minimized mounting for sensitive capacitors. In addition, our patented PCB construction ensures that the signal is completely freed from disruptive resonances.

Motor

The motor in our turntables is a brush-equipped, ironless DC motor from the Swiss manufacturer Maxon. It features precious metal brushes and sintered bearings for exceptionally quiet operation.

Thanks to its ironless design, the motor runs completely cog-free, ensuring perfectly smooth rotation of the platter.

Before installation, each motor undergoes a break-in process and careful selection—only the very best are used in our turntables.

Controlled via app

Our motor controllers can be configured via Bluetooth using our app. A special highlight is that the control parameters of the three different PID controllers can be adjusted directly in the app, allowing fine-tuning of the turntable’s sound.

The characteristics of the three motor mappings are factory-programmed as follows:

Dynamic – optimized for lively, open, and detail-rich playback.
Harmonic – relaxed, spacious, and natural sound.
Pure – minimal control intervention, acting only when rotational speed deviates by 0.5 percent.
