The cartridge release for exclusive use of the monaural LP of a new method

We deny an existing monaural cartridge so far.

The existing structure is because I cannot play a monaural LP faithfully.
And we made a cartridge for exclusive use of the monaural LP with a vertical axis concentration method.
The cartridge of the vertical axis concentration method plays a monaural LP faithfully.

 

 

The monaural cartridge developed in the monaural music times is made to play only a monaural LP.

The cartridge of the monaural music times does not work lengthwise, and it is made with the structure that can trace the amplitude by the movement of the cross direction precisely.
I evolved a monaural cartridge of the time more, and a cartridge for exclusive use of new monaural recording was born.

structure

Why is a monaural cartridge necessary in the present age?

There are a lot of monaural LPs to excellent records such as classical music, jazz, a lock.
When I look for the LP of the excellent performance, monaural recording knows a thing more than the half.
And I want to come to listen to a monaural LP by a good sound.

There are people purchasing a monaural cartridge easily.
And there are people playing a monaural LP with an existing monaural cartridge and stereo cartridge.
The people feel a monaural LP like an old sound by the influence of the cartridge.
And an image is left as an old LP.
In fact, the monaural LP has better sound than the stereo LP.
The reason is simple.
It is natural that a sound is better than the stereo LP to put two signals in as for the monaural LP which installs one signal in one ditch.

 

We pursue that we hear a splendid performance from an LP.
It is the most important for a hobby called the audio system.

The monaural cartridge of the vertical axis concentration method is a patent of the Miya-jima laboratory.

By the method, the wide blurring of the coil decreased, and the needle was easy to work aside and did not move at all lengthwise.
Therefore the generation by a highly precise turn became ideal and was able to change the amplitude of the groove of the monaural LP into a sound precisely.
The vertical axis concentration method expresses space of the best monaural music.

 

The cartridge of the vertical axis concentration method plays only a monaural LP. It cannot play a stereo LP with this cartridge.

When it played a stereo LP with this cartridge, a sound is that a distortion and a needle do not work lengthwise, and there is the thing that a needle injures the ditch of the LP.

 

As for blue note LP of the 1,500th level and the 4,000th level, the sound of the cello of Casals and Beatles LP of the product made in U.K., the splendid performance in those days is recorded. And its music revives wonderfully when this cartridge plays a monaural LP.
