Ortofon SPU Synergy GM Cartridge



全鑽石針頭, 橢圓, 鑽石針 唱頭 SPU Synergy GM The SPU Synergy modernizes the classic SPU design with a number of optimizations developed for optimum compatibility and sonic purity. The SPU Synergy transducer system allows extraordinary synergy of sonorous sound. Very low coil-resistance combined with unusually high output of 0.5 mV, achieved by using Neodymium magnets, is decisive for reaching the high signal-to-noise ratio. The exceptional black polished Urushi painting on the SPU Synergy wood-based housing suggests a precious jewel-like appearance. A revised generator system, which allows for a maximum output of 0.5 mV, relaxes the requirement for high gain transformer or active pre-amplifi cation systems. 丹麥 Ortofon SPU Synergy GM 唱頭


Product Features:

Choosing an Ortofon SPU cartridge for your turntable. All Ortofon SPU-cartridge models are highly indebted to their SPU-ancestor launched in 1958, when the original Ortofon stereocartridge was born. So, ever since the various Ortofon SPU - models announced in this manual, have never compromised with the basic design - responsible for the so-called “Ortofon Sound”, world wide related to these cartridges. Refinements on the models have taken benefit from the use of new materials and improved stylus types, to gain the outstanding reproduction qualities. Mounting All SPU-cartridges are designed to bring optimum performance, when the tonearm mounted with the cartridge is adjusted parallel to the record surface, at recommended tracking force.

When antiskating adjustment is possible, we recommend a 50% higher value, when using SPU-cartridges with the Ortofon Replicant stylus, compared to normal setting at recommended tracking force.
