Sonorus Minor Turntable

The Sonorus Minor Gramophone is a high-end analog gramophone designed for amateurs of audiophile sensations and high-end playing equipment.

The aluminum plate of this gramophone has a diameter of 300 mm and weighs about 21 kg. Such a high weight ensures very high rotation stability.

The plate is mainly suspended on neodymium magnets, which effectively minimizes friction resistance and significantly reduces the vibrations of the disc itself and the influence of external vibrations (for example from loudspeakers).

The disc’s axis is constructed in a way characteristic for Sonorus gramophones. It is made of surface hardened steel, and at the top there is a ceramic ball. On which the aluminum cylinder with bronze bushings rests, very precisely aligned with the axis.

Thanks to the use of neodymium magnets, the effective weight of the platter drops to approx. 1-2 kg, which significantly reduces friction resistance.

The disc drive is a synchronous DC motor connected to it by means of a belt, stabilized with quartz.

The plate can rotate at two speeds – 33 1/3 and 45 rpm.

Arm with a length of 12 inches is available in three variants – as made of polished aluminum, chromed brass or carbon fiber. This allows you to choose the characteristics of the arm to the user’s chosen cartridge. For amateurs there is also a luxurious version – a carbon fiber arm on the wrist made of gold-plated brass.

The design of the articulated arm includes ball bearings thanks to which the arm achieves great precision of movement. This solution also allows to minimize friction resistance. The base of the arm is a polished aluminum cylinder with two RCA sockets available and a ground socket.

You can install a 10-inch arm.

The design of the arm gives the possibility to use cartridges weighing from 4 g to 15 g. You can use both MM and MC cartridges.

The weight of the whole structure is approx. 35 kg
