Modi turntable from Bergmann Audio, is the entry level model – an affordable way to the advantage of airbearing technology.
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.
Odin – Tonearm
In the Nordic Mythology, Odin is an extreme central God. Together with his brothers, he is creator of the world and man. Odin is the wise God. He is also the God of poetry, providing the poets with ecstasy and wisdom to express themselves. As a God of war, Odin also plays his role, and acts more like the strategist, who sets up his army, and as the God who ensures victory.
Design
In the design and construction of Odin, we stay to our idea of simplicity: As few parts and assemblings as possible, to avoid resonances.
A parameter in the ultimate tonearm design is stiffness and stability in the construction. Both are carefully incorporated in the Odin arm. An example is the airpipe, which is fixed in both ends, to give the floating part the best possible base.
The armtube is traditional for Bergmann tonearms- well considered construction in few parts, made as a double tube construction, with damping in between the tubes. This means that the armtube control the vibrations from cartridge and record grooves when handling the musical crescendos.
The tonearm wire is- as usual in Bergmann tonearms- in one piece from cartridge clips to the DIN connector. The DIN connector ensures user flexibility for connection of the prefered interconnect phono cable.
Counterweight is decoupled from the arm- again to avoid any resonances.
Floating part – perhaps the most important part, of an airbearing tonearm!
The first part of the tonearm to handle modulations from the record groove and cartridge, is the moving part of the tonearm. Head shell, armtube, sliding pipe and counter weight, has to be well considered and well assembled, to avoid any resonances to disturb the delicate signal.
The head shell is a very stiff construction, machined of one solid piece of aluminium, glued by 2-component epoxy onto the seamless carbon fiber armtube, which is a double carbon fiber tube construction with damping in between, to avoid coloration to the sound. The armtube is fixed in a groove, on top of the sliding pipe, which is machined of 2 pieces of solid aluminium and glued by 2-component epoxy.
The space between the airpipe and the sliding pipe, is 50 micron, as we found this as the most userfriendly.
The azimuth adjustment is very well considered – a slot on the bottom side of the head shell, where an “azimuth-plate” perfectly fit = 100% contact, the azimuth is simply adjusted by tighten or untighten the 2 screws holding the cartridge, and then twist the cartridge to a perfect azimuth. At Bergmann Audio, we don’t believe in a twistable head shell in the armtube, as this solution never will be as strong and stiff, as the construction we have made on the Odin tonearm.
The tonearm wire is made in one piece from the cartridge clips to the DIN connector, to secure as pure signal transmission as possible.
- Headshell machined in solid aluminium. The design ensure optimal stiffness.
- Azimuth plate. 100% contact to the headshell and cartridge.
- Armtube is a double seamless carbon design, with damping in between.
- Sliding pipe floats completely frictionsless on the airpipe.
- Tonearm wire in one piece from cartridge clips to the DIN connector.
- Counter weight, decoupled from the armtube by 3 rubber strings.
Air supply
The air supply has been the object of our greatest attention. The goal is to design a silent air supply, which could be placed in the listening room, and deliver an even, clean and dry air flow.
The pump is an oil free, long life unit, which do not require much maintenance.
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. The filter is replaceable when necessary.
