Intro video
Get down to the details as Leif Johannsen, Ortofon's Chief Officer Acoustics and Research, takes you on a journey through cartridge design. In this four-part video series, you will learn everything there is to know about:
1. How does a cartridge work?
2. What are cartridge technologies?
3. What materials go into a cartridge?
4. What types of styli are there, and how do they differ?
Chapter 1: Cartridge Principles
How does a phono cartridge work?
In this video, Leif Johannsen introduces you to two main cartridge principles: Moving Magnet and Moving Coil. Both principles have advantages and open up different possibilities for the design of the cartridge, including the use of material, implementation of technologies, and the choice of styli. You will learn how the two systems work differently, how the music is conducted from the groove and travels true the cartridge, and how each principle benefits differently.
Chapter 2: Cartridge Technologies
What are cartridge technologies?
In this video, you will learn about four cartridge technologies, how they work, and how they can improve the listening experience. Leif Johannsen, Ortofon's Chief Officer of Acoustics and Research, will take you through the physics, and you will get to understand everything about:
1) Split Pole Pins, which is about magnetics, and how to reduce the loss of energy and, as a result, reduce the loss of the musical signal.
2) Selective Lazer Melting, which is about making houses with no unwanted vibration.
3) Field Stabilizing Element, which is about improving the properties of the magnetic field in the moving coils and, finally
4) Wide Range Damping, which is about enhancing the properties of the rubber suspension system in the cartridge.
Chapter 3: The Power of Materials
What materials go into a cartridge?
Chapter three delves into the power of materials used in the different parts of a cartridge and their significant impact on its performance. The chapter covers the following:
1) Cartridge housing, where Leif Johannsen discusses the different benefits of the materials used in cartridge housings.
2) The magnetic system, where you will learn about Neodymium Magnets and their high energy density.
3) The rubber suspension system, where Leif Johannsen demonstrates the differences in the damping properties of the rubber, and you’ll get a look inside the Ortofon Rubber Facility.
4) The Armature, where you will learn about the magnet, semi non-magnetic and non-magnetic armatures.
5) The cantilever, where you’ll learn about the various materials used for cantilevers, including aluminum, boron, and diamond.
