Odin tonearm - Bergmann Audio
Linear tracking airbearng tonearm - Odin Tonearm
The most universal linear tracking airbearing tonearm.
Odin Tonearm fit most highend turntable designs- incl. the Bergmann 4-arm turntable model Galder.
The linear tracking tonearm, on Odin 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 it has no mechanical contact (the moving part) to 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.

- Airpipe supported in both ends, for optimum stiffness.
- Base plate. Can be moved forth and back, to obtain perfect overhang and for perfect leveling of the
airpipe. - VTA plate- where all functional parts are fixed.
- VTA adjustment screw.
- VTA pillars fixed to the base plate. VTA plate can be adjusted on the pillars by turning the VTA adjustment screws.
- Screws to tighten the VTA plate, when VTA is adjusted.
- Air input, to support the floating part with an extremely frictionless air cusion.
- Air flow can easely be adjusted by a valve at the airsupply.
- DIN connector, to fit all brands of phono cables.
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.
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.
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.
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.
