Bergmann Audio Modi Turntable

Advantage Of Using Air Bearings

The platter is centered by a steel spindle running in a very frictionless, low noise and hard wearing polymeric bearing material and also floats on a thin air cushion which lowers the mechanical bearing noise to an absolute minimum - if any. (A Traditional bearing solution which keeps the platter centered AND support the platter weight, makes a higher level of mechanical bearing noise as the contact point between spindle top and platter generate a very high pressure - and hereby noise).

By floating on an air cushion the platter also gains the advantage of a very good isolation from the surroundings, same way as the known - and very expensive - air supported shelf, used in many high-end audio systems.

Plinth

The plinth is made of one solid piece of CNC-machined composite material which is standing on three adjustable feet. The platter is belt driven by a DC tacho motor. The platter will be kept at a very precise speed via communication between the tacho and the high precision motor control electronic. Measured by Bruel & Kjær equipment, speed variation 0.003%.

The DC tacho motor is decoupled from the plinth by an isolating layer of sponge rubber between motor and plinth. Sponge rubber have a very high degree of vibration absorption due to the high density of air pockets in the construction. That will prevent any motor vibration transmitted to the plinth.

The air supply is remote controlled from the Modi plinth. When turning off the platter after listening, the air supply goes “OFF” automatically 2 minutes later. A user friendly and convenient feature.

Armboards

Modi accept 2 tonearms – radial- and linear tracking tonearms. As standard, Modi comes with a main armboard to fit almost any tonearm brand on the market – 9”-12” tonearms.

If a different tonearm is desired at a later stage, only the insert has to be replaced.

For Modi and Galder Turntables.

Air Supply/Power Supply

The air pump must deliver an even, clean and dry air flow.

The impulses from the pump are absorbed in an encapsulated reservoir. This results in an even airflow to the air bearing. The air supply is mounted with a filter which prevents dust particles in entering the system. This filter is replaceable when necessary.

The pump is an oil free, long life unit, which do not require much maintenance.

The air supply box houses the Modi communication electronics, power supply, and air pump. By just pressing the 33 or 45 rpm bottom, the turntable plinth controls the air supply. First press, the air goes “ON”, second press the platter start to spin. When the platter is turned “OFF”, the air supply turns “OFF” automatically after 2 minutes.
