Basic knowledge of the stylus

The phono is the key to determining the tone. According to the magnetoelectric conversion method, the phono is divided into three types: dynamic magnet (MM), moving iron (MI) and moving coil (MC):

MM, Moving-Meganetic Cartridge

Fix the coil in the cartridge, with a small magnet at the back of the needle bar, a small rubber damping in the magnet, the rubber damping as the support point, and the sound signal in the groove to vibrate the small magnet through the stylus. The action of magnetic line cutting is generated to obtain an output level. Shure is a representative manufacturer of moving magnetic pickups.

MI, Moving-Iron Cartridge

It consists of a fixed magnet and a coil, and the iron core is driven by the needle bar to change the distribution amount of the magnetic lines of force, thereby outputting a level signal. The moving iron cartridge is represented by GRADO in the United States.

MC, Moving-Coil Cartridge

A small, thin coil is wound around the back of the needle bar, and the vibration of the needle bar drives the coil to vibrate and thereby produces an output. The moving-type cartridge of Ortofon in Denmark is representative. Usually, the fewer the number of coils wound in the moving coil cartridge, the lower the output; the more the coil is wound, the higher the output.


The moving-type cartridge has the advantages of strong resolving power, high-frequency response, and rich sound details, but the moving magnet and the moving iron cartridge have better tracking ability than the moving coil cartridge, and the moving iron and moving magnet The output power of the cartridge is relatively high. The two do not need to increase the amplification or use the booster. The manufacturing cost is relatively low, and the stylus can be replaced by itself. It is convenient for beginners.

Stylus

The needle tip of the stylus can be divided into a round tip, an elliptical tip, and a super elliptical tip. The super-elliptical stylus produces the highest bandwidth and the worst round shape. A round needle is less likely to jump, but the sound is not as good as an elliptical needle, but the elliptical needle has a higher loss rate. SCRATCH usually uses a round needle, the round stylus is easier to adjust, and the ellipse is prone to problems such as noise, wear, positioning, etc., and no one takes the elliptical needle to SCRATCH.

Adjusting the cartridge

The angle of the cartridge needs to be adjusted. Its angle is directly related to the contact of the stylus in the groove of the disc, which directly affects the degree of the signal received by the stylus. If the angles of the various cartridges are not accurate, not only will the sound monotonous, the two-channel volume is incorrect, the phase is incorrect, the noise is increased, etc., but the positioning is not accurate, the two-channel sound is unbalanced, and the sound quality is not Good, incorrect tone, dull voice and other issues. To put it simply, the adjustment of the horn angle is to face the phono and swing the phono in a clockwise or counterclockwise direction. Follow this adjustment step and listen carefully with your ears: When you hear the most harmonious, the least sharp, the sound layered, the most clearly positioned, the least murmur, the angle of the cartridge has been adjusted to just the right .
