The sub-chassis turntable without compromise
Experience tradition in its origin

The sub-chassis is made of triCom, an aluminium/POM composite characterized by excellent damping properties and high stiffness. Its weight has been optimized for high performance. To reduce vibrations, the synchronous AC motor is mounted directly onto the damped sub-chassis. It drives the sub-platter via a machined precision belt.

The sub-chassis is suspended by means of three conical springs which can be adjusted from above in order to achieve uniform tension. The bearing is made of sintered bronze with a Teflon thrust pad and optimized for smooth running. The steel axle supported therein provides very low, constant friction and thus presents a uniform load to the motor. Two of the turntable’s three feet can be levelled from above, which facilitates setup.

Depending on the model, different damping architectures, tonearm boards and platters are used. The design can accommodate a wide variety of 9" and 10" tonearms also from third-party manufacturers.
