YAMAHA MC-5

Commentary

MC type cartridge that uses beryllium, tapered pipe and cantilever.

The cantilever uses a high-purity beryllium tapered pipe cantilever developed by Yamaha's proprietary electron-beam vacuum evaporation method, resulting in an excellent equivalent mass of 0.096 mg for the cantilever alone and 0.167 mg for the total vibration system.

Newly developed Equalizing Damper is used for the damper part.
This damper has a structure in which a step is consciously provided on the surface that contacts the upper part of the armature in the V direction. When a needle pressure (1.2g) is actually applied, the cantilever is controlled so that the center of gravity of the vibration system is on the straight line connecting the tension end and the vibration supporting point. This clarifies the vibration system operation, and by using this step, the compliance in the V direction is appropriately controlled, and adverse effects such as warping of records are suppressed.
In addition, the newly developed damper is stepped to vary the thickness and shape. This satisfies both the condition of widening the contact area required for low-frequency reproduction and the condition of making the contact area small and thin for high-frequency reproduction, and realizes uniform spectral balance over all frequencies.

Yamaha's unique cross power generation system that easily controls crosstalk and Sendust core that greatly reduces annoying Barkhausen noise.
