ZYX

The world's first High-speed generation system
Eddy currents which occurs in generation system raises the magnetic impedance in the circuit and affects to the transient response of the sound signal, and as a result, the reproduced sound is badly deteriorated. Eddy currents which occur on a pair of opposite pole faces (N pole, S pole) reverse phase each other. There should be a solution to eliminate such eddy currents.
However, ZYX has discovered that there are two pairs of the eddy currents existing in the magnetic circuit and therefore, it is necessary to neutralize and eliminate these two pairs of the eddy currents at once. The “Premium” series cartridges are equipped with a new “Balanced type eddy current elimination mechanism” which we developed to solve this problem, and succeeded to reproduce an accurate time axis of the sound signal by non-magnetic impedance.

Employment of a new suspension wire
The new material which was not thought about in the past are developed one after another. One of them is a thin and tough material while being flexible.
The suspension wire of MC cartridge is to hold and position the fulcrum of the rotary vibration of the cantilever, and a hard metal wire like piano wire has been commonly used conventionally.
Instead of a hard metal wire, we employed in Premium series new optimal material without aging, tough and of superior temperature characteristics. This brought an improvement in tracking ability and a sense of pitch that soaks into a soul. As a result, the true analog sound of Premium series was further improved in the sense of reality.

15 items in generator
ZYX only succeeded in development of a MC cartridge which does reproduce original stereo sound with a perfect sound balance between the left and right channel.

2 Layer Laminate Armatures
4D has an armature made with double layers, facing each other with opposite polarity, namely one laminate to face N-polarity and the other S- forming mutually reversed phase positions in order to short-circuit and simultaneously dissolve both eddy-currents generated in each armature.

Super High Speed Reproduction Engine (magnetic circuit)
Premium 4D is employed with the super high speed reproduction magnetic circuit which was first introduced in the world. This circuit is specially processed to null magnetic resistance within magnetic gap, and enables high speed power generation against signals over entire bandwidth straightly without time delay. Even higher harmonics elements that determine the texture of each musical instrument can be simultaneously reproduced, and delivers quite smooth, natural, dynamic and realistic sound.
