Ortofon CC DJ S Twin Cartridges.
This is the blue working horse for scratch and back cueing, mounted with spherical diamond.
It has an extraordinary rigidity because of a specially developed reinforced cantilever.
It achieves an output of 6.0 mV.
Several Ortofon technologies make it possible to realize high sound quality and low record wear at the high tracking forces that are necessary in disco environments. DJs all over the world claim very high demands to their professional equipment, among which the cartridges plays their decisive part by realizing that scratching, back-cueing, and live artistic performance are a big part of the show. Reliability and robustness is vital, when the cartridges night after night will have to withstand these demands in environments with extreme sound pressure and vibration.
Scratching and back-cueing impose heavy mechanical stress on the cantilever and its rubber bearing. Therefore, the Ortofon disco cartridges are equipped with cantilevers made from aluminum tube with increased wall thickness. Special attention has also been paid to the attachment of the bearing and the design of the bearing itself. This means that rough treatment will neither damage the cartridge nor degrade its stability.
For easier cueing, the nose of all the Ortofon disco cartridges have an extra large cut-out which makes the stylus freely visible from above, and further, the tip of the cantilever is fluorescent.
