i have 3 almost new ortofon concorde djs cartridges and 6 dj stylus / needles i have 2 silver stylus and 4 dj blues and the carts and 3 needles have been used for no more than 8 hours and the other 3 are new....this is a great deal for any dj.... these are pure works of art... Ortofon CC DJ S KitDj's all over the world can claim very high demandsto their professional equipment, among which the cartridges "plays" their decisive part by realizing the artistic scratching-back-cuing and mixing work, 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 sound pressure and vibration. Many years of experience from producing PRO-cartridges, and a close contact to DJ's have now resulted in new Ortofon versions directly addressed to the user by the name DJ. Robust Cantilever We have found a number of vital features which quite natural must be required by the DJ's to fulfil their professional job. The new Ortofon DJ cartridges offers a very clear visible cantilever with a red stylus point, which makes it very easy to locate the stylus in the groove. Robustness of the cantilever itself is also vital for a discotheque cartridge, w rough handling is part of normal use. As a consequence the new Ortofon DJ cartridge has been provided with a special telescopic cantilever construction, consisting of a double tube design w the diameter of the outer tube at the same time has been raised from 0.7 to 0.8 mm. By doing so, an extraordinary rigidity of the cantilever has been achieved, without distorting the frequency response and tby the well-known Ortofon accuracy in sound. Antiskating Trackingability is decisive for DJ's especially when doing scratching and back-cuing. In this situation raise of tracking force could be an immediate, but in many cases not very effective solution. The reason is that antiskating adjustment, if not a very moderate level, will double skating effect when back-cuing. So, as a rule, never use more than one half of normal antiskating related to the tracking force. To make the cartridge even more resistant against violent handling, such as drop on the platter-mat or touch of fingers etc. we have made the suspension of the cantilever more rigid against, axial pull. The Stylus units for the new Ortofon cartridges will appear in our special elliptical as well as our spherical versions. One Finger Fingerlift Output has a considerable influence on good working conditions together with amplifiers, first of all in the relation between signal and noise. The new Ortofon DJ models expose the highest output compared to any other makes. The design will be the well known Ortofon Concorde as well as the Ortofon half inch models. Both types will appear in a new cobalt blue color made from a new very strong Nylon material, which will made it almost impossible to break the fingerlift on the Concorde model. From DJ's we have had the request, that the fingerlift ought to work more easily and quickly when just being touched underneath with one finger. To help in this situation, we have now designed a rubber tube that can be placed over the plastic finger and tby improve friction.
