Bergmann Audio Modi & Thor

Modi & Thor

The name Modi means “courage” or “brave”. He is the son of Thor and Sif, and represents the characteristics of his father. He is told that he will survive Ragnarok and- together with his step brother MAGNE– carry on Thor’s strength and qualities.

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 floats on a thin air cushion, which lower the mechanical bearing noise to an absolute minimum- if any. (A traditional bearing solution, which keep 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, generates 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 shelfs, used in many highend audio systems. Also the speed stability benefit from the air supported platter. The musical flow is really extraordinary – not necessarily measurable but audible.

Plinth – Modi Turntable

The plinth is made of one solid piece of cnc-machined composite material, which is standing on 3 adjustable feet. The platter is belt driven, by a DC tacho motor. Communication between the DC tacho motor and the high precision motor control electronic, will keep the platter in a very accurate speed. 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 Turntable

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. An additional armboard for almost any tonearm brand, is available for the Modi turntable.

Airsupply/Powersupply – Modi Turntable

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 airsupply box, contain air pump, powersupply and communication electronics for Modi. The airsupply is controlled from the turntable plinth, just by press either 33 or 45 rpm bottom. First press, the air goes “ON”, second press the platter start to spin. When the platter is turned “OFF”, the airsupply turns “OFF” automatically after 2 minutes.

Thor – Tonearm

Thor was the most popular of all Gods. Thor was worshiped by most – he was the God of people. He made lightning and thunder as he drove over the clouds in his chariot drawn by goats swinging with his hammer, Mjølner. Thor stood for physical strength. Thor`s role was among, to maintain law and order.

Design – Thor Tonearm

In the design and construction of Thor, we stay to our idea of simplicity: As few parts and assembling as possible, to avoid resonances. The carbon fibre armtube is traditional for Bergmann tonearms- well considered construction in few parts, made as a double tube construction, with damping in between the tubes, to avoid any coloration in the signal path, generated by the stylus tip and the record groove. Even the most powerful musical passages in the music, will be reproduced with musical ease and very low distortion. The tonearm wire is- as usual in Bergmann tonearms- in one piece from cartridge clips to the DIN connector. The DIN connector ensure user flexibility for connection of the preferred interconnect phono cable.

Counterweight is decoupled from the arm- again to avoid any resonances.

Strength in the linear tracking airbearing tonearm

The Linear tracking tonearm tracks the record as it is pressed = no tracking error. The benefit is a distortion free and relaxed reproduction, even at complex passages. One more important advantage of the airbearing is the tonearm’s immunity to acoustic feedback, as the floating part (armtube and head shell) has no mechanical contact to the fixed part of the tonearm, and the turntable.

The only contact is through the stylus tip and the tonearm wire. Timbre, details and nuances, is a natural part of the transparent and vivid acoustic image. The 3D spaciousness, layering between instruments and zero tracking error is something traditional tonearm finds hard to achieve.
