Ortofon GT DJ Cartridge DJ's all over the world claim very high demands to their professional equipment, among which the cartridges ``plays" their decisive part by realising the scratching, back-cueing, and live artistic performance, as 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 soundpressure 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 aluminium 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. The Ortofon Pro cartridges were the first to combine the unrivalled Ortofon sound quality with the ruggedness that is a must for professional use. Many years of experience from producing disco cartridges, and a close contact to DJ's, have resulted in several lines suitable for all tonearms and all amplifiers. The Ortofon disco cartridges are available in inch versions for mounting in standard headshells or in the elegant integrated Ortofon Concorde design - for direct mounting in tonearms with standard sockets. For easier cueing, the nose of all the Ortofon disco cartridges has an extra large cut-out which makes the stylus freely visible from above, and further, the tip of the cantilever is fluorescent.
