What exactly is a 75 ohm connection and what do I need it for?

On some Soundmaster models you will find the so-called “75 Ohm connection” among the existing connections. But what do I actually need this for?

In short: it sounds better! Here we explain the whole thing in detail:

A 75 Ohm connector is a special coaxial connector used in the transmission of high frequency signals, especially in television and radio technology. The term "75 Ohm" refers to the impedance of the cable and connector. Here are some key points to help you understand the 75 Ohm connector:

Basics of Impedance

• Impedance (Ohms) : A measure of the resistance offered by a cable or connection to the flow of alternating current. It is measured in ohms (Ω).
• 75 Ohm : This impedance is standardized and optimal for the transmission of TV and radio signals as it ensures minimal signal loss and reflection.

use

• TV and radio technology : 75 Ohm connectors are widely used in antenna cables for televisions and radios. They are the standard for connecting antennas, cable boxes and satellite receivers.
• Cable Types : Coaxial cables with 75 ohm impedance are typically known as RG-59 or RG-6. These cable types provide optimal signal transmission for high frequency signals.

Physical Properties

• Coaxial cable : Consists of an inner conductor, a dielectric insulator, an outer conductive shield and an outer sheath. The 75 ohm impedance is determined by the ratio of the dimensions of the inner conductor and the dielectric material.
• Connectors : Typical 75 Ohm connectors are F-connectors, BNC connectors and RCA connectors. These connectors are designed to maintain the 75 Ohm impedance and ensure a good connection.

Why 75 ohms?

• Signal quality : 75 Ohm connectors and cables minimize signal loss and reflections, which is especially important when transmitting high-frequency signals such as television and radio signals.
• Compatibility : Most TV and radio receivers are designed for an impedance of 75 ohms, making them the best choice for such applications.

Summary

A 75 ohm connector is a coaxial connector that is ideal for transmitting high frequency signals such as TV and radio signals. Its standardized impedance of 75 ohms ensures high signal quality with minimal loss and reflection, making it the preferred choice for TV and radio applications.
