The arm's entire tube and head shell is machined from a single piece of solid aluminium alloy and undergoes sixteen engineering operations to achieve the head shell construction, this ensures the arm's rigidity and hence promotes musical precision. The Artemiz uses Roksan's Intelligent Counterweight System which dynamically optimises the tracking force. Single point suspension minimises the transmission of unwanted mechanical noise to the cartridge and the low centre of gravity improves dynamic stability. Unique pyramidal bearings lower friction and allow for rapid changes in direction and speed that tonearms experience. Additionally, optimum matching to the weight of the cartridge is achieved using different counter weight blocks. The Artemiz fixing clamp and washer maximise the force required to couple the tone arm to the armboard correctly. To ensure excellent signal transfer and complete noise immunity, the Artemiz is fitted with a printed circuit board in lieu of internal wires. Left and right signal tracks from the cartridge are shielded all the way by ground tracks on either side. Unique arm tube, bearing and arm coupling design of the Artemiz increases the first resonance break of the arm to 1.4kHz almost 50% higher than other high end tone arms and thus provides the cartridge with the best platform to track records and retrieve maximum information with live performance like dynamics.
