Warsaw · Named for Chopin

The motor is the drive. Nothing in between.

A coreless direct-drive motor and a 720-point optical encoder correct the Fryderyk's platter speed in real time, holding wow and flutter below 0.09%.

The drive

Typ GSH-630 Zakład Warszawa

720 marks a revolution. Each one checked.

The NB1 motor is coreless, brushless and bolted straight to the platter. An optical encoder reads 720 marks every revolution, two Hall sensors read the motor itself, and the controller corrects speed while the record plays. Wow and flutter stays under 0.09 percent. The R10 arm rides on two pairs of bearings on tapered pivots and arrives with an Ortofon 2M Bronze already aligned.

Under the Platter

What holds the groove

<0.09% Wow & Flutter

Held there by dual Hall-effect sensors and a 720-point optical encoder correcting motor speed in real time.

720Optical Reference Points

Read once per platter revolution and fed back into the NB1 motor's digital speed-control loop.

1.6kg HDPE Platter

A dense polyethylene platter with felt mat adds inertia and damps resonance between stylus and bearing.

What cartridge comes fitted to the GSH-630 Fryderyk?
The Fryderyk ships with a factory-fitted Ortofon 2M Bronze moving-magnet cartridge, pre-aligned on the Unitra R10 tonearm and ready to play out of the box.
Is this a belt-drive or direct-drive turntable?
Direct drive. Unitra's proprietary NB1 coreless motor spins the platter directly, with a digital control loop that reads 720 optical reference points per revolution, backed by Hall-effect sensors, to hold speed steady.
Do I need a phono preamp to use this turntable?
The GSH-630 outputs a standard phono-level signal through gold-plated RCA connectors and has no built-in phono stage, so you'll need a phono input on your amplifier or a separate phono preamp.
What speeds does the GSH-630 support?
33⅓ and 45 RPM, selected at the front panel and held by the digital speed-control system. No pulley to move.
How heavy is the turntable and does it come with a dust cover?
The complete unit weighs 11.7 kg and includes a thick hinged dust cover with heavy-duty, adjustable-tension hinges.
What finishes are available?
The plinth combines a brushed aluminum front panel with real wood veneer, offered in walnut and ash finish options with silver or black trim.
About the Unitra GSH-630 Fryderyk Direct Drive Turntable

Polish Precision, Reborn — The Fryderyk Direct Drive Turntable

The Unitra GSH-630 Fryderyk Direct Drive Turntable is a benchmark for what a modern European turntable can be. Built around Unitra's own NB1 air-core brushless direct-drive motor and digital speed controller, it spins with the quiet authority of a much costlier deck — and arrives ready to play, fitted with an Ortofon 2M Bronze cartridge on the aluminium Unitra R10 tonearm. Milled veneered MDF, a brushed aluminium panel and an HDPE platter make it as beautiful to look at as it is to listen to.

Direct Drive, Done Right

At the heart of the Fryderyk sits the Unitra NB1 direct-drive system: an air-core brushless DC motor governed by a digital controller that holds pitch with rock-steady stability. Wow and flutter measures below 0.09%, so pianos stay in tune and sustained notes never waver. There's no belt to stretch or replace, and no idler to wear — just direct, immediate torque that locks to speed instantly.

Tonearm and Cartridge Ready to Sing

The aluminium Unitra R10 tonearm rides on two pairs of bearings mounted on tapered pivots for low friction and precise tracking, and it comes pre-fitted with the respected Ortofon 2M Bronze moving-magnet cartridge. Out of the box, the Fryderyk is a complete, high-performance analogue front end — unbox it, set it on your rack, connect the RCA outputs and drop the needle.

Why You'll Love the GSH-630 Fryderyk

  • Unitra NB1 air-core brushless direct-drive motor with digital speed control
  • Excellent speed stability — wow & flutter below 0.09%
  • Aluminium Unitra R10 tonearm on twin tapered-pivot bearings

Frequently Asked Questions

Does the Fryderyk come with a cartridge?

Yes. It ships pre-fitted with an Ortofon 2M Bronze moving-magnet cartridge on the aluminium Unitra R10 tonearm, so it's ready to play out of the box.

Is it belt-drive or direct-drive?

Direct-drive. The Unitra NB1 air-core brushless DC motor couples directly to the platter under digital speed control, delivering instant torque, stable pitch and no belt to replace.

What speeds does it play?

33⅓ and 45 RPM, both digitally controlled for consistent accuracy.
