Moving Coil Phono Cartridge

4D

The factors that can be documented as data of an audio component such as frequency response and distortion characteristics are only two dimension. Frequency (X) and level (y) where a sound is structured by three dimensional factors including time (z) then a question comes how the time (z) response is presented in audio equipment. I have found that exactly the time factor Z is very important to represent playback sound quality. Analog recording that contains the same continuously sequential Z information as the sound in natural world is essential in real sound playback as known and makes it possible to reproduce sounds that are natural and clear. Three dimensional image oriented and sensitive and wide range.

ZYX MC Phono cartridge are designed and built with this important central factor Z and unparallel in the world they enable time responses begin even over the entire range. Resultant gain are equal sound quality on both left and right channels flat sound balance and clear stereo sound flied as widely accepted by users.

Further, ZYX 4D model has come out with newly added feature each of which is upgraded for better sound image orientation, clear outline expression, purer stereophonic sound field, and more realistic acoustic space so that you will recognize again the amazing sound information of analog playback. The 4D has four dimensional factors that realize reproducing new three dimensional music whenever, whenever and repeatedly going beyond time and space.

Newly Developed Features

2 Layer Laminate Armatures

An armature which is the frame whereon generator coil is wound is key part as center of all mechanical vibration in generator system. It simultaneously affects electrically an audio signal from coil output and quality of reproduced sound. For reproduction over wide range, it is indispensable to reduce numbers of coil turns and equivalent moving mass in vibration system, and to cover resultant drop in output voltage a high-permeability metal having 6 times more efficiency than an empty core is generally used as armature material.

On the other hand a metal armature generates induced eddy-current over armature and disturbs the flow of audio signal generated by a coil. Induced eddy-current is extremely minute so it might have been considered least influential, but we should not neglect its influence now that we aim higher quality of sound level. ZYX has succeeded in taking the most effective measures to meet this situation into 4D for the first time. We made the armature structure have double layers facing each other with opposite polarity mainly 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 current generated in each armature. As the result double layer armatures showed immeasurable effect and are presenting new world of sound we never experienced before. For sure you will sense animate sounds which are beyond those mechanically reproduced on every count such as vocal, piano, violin and every other musical tones in texture, Dynamism, too realistic noiseless sound feeling. This is what reproduction of original sound means.

Semi-Skeleton Body

Any phono cartridge aiming higher sound quality should never show body resonance, which feedbacks to vibrate generator system that has to be kept statically. To be free of body resonance, 4D has introduced for the first time in the world a semi-skeleton body without side panels that are most apt to produce resonance. It is basically pillar structured like Parthenon to be one of the factors of clear sound without inter-modulation.

• REAL STEREO Generator System: world’s first 15 vital design points as our know how

• World first cryogenically Treated Magnetic Circuit: the cryogenic temperature is -196c (-320F) that is the lowest temperature among other commercial cryogenic methods. Under this lowest temperature, the metal parts come to be purified for regularizing the molecular structure to the original state.

• Pure Silver Wire Generator Coils: 4D-S version uses cryogenically treated 5-N silver wire made in USA. It can easily make the sound to extend high range and be transparent mid and low range.

• 6N Crystallized Copper Wire Generator Coils: 4D-X version uses cryogenically treated single crystal copper wire for the first time in the world. You will find a new sound world never expected.

• The Most Superior Cantilever: 4D series uses an ideal boron solid cantilever which created a cantilever of the lowest mass, the highest rigidity and the fastest response to most dynamic.
