Introduction to audio/video electrical cables

Audio/video electrical cables are conductors specifically designed to transmit audio and video signals between electronic devices. These cables guarantee the quality and fidelity of the signal, allowing correct sound and visual reproduction in entertainment, communication and professional systems.

These cables differ from other electrical cables due to their technical and construction characteristics, which minimize interference, signal loss and noise, fundamental factors to maintain the integrity of the transmitted information.

coaxial cables

Coaxial cables are commonly used for the transmission of analog and digital video signals. They are composed of a central conductor, an insulating layer, a metal screen and a protective outer cover. This construction allows electromagnetic interference to be considerably reduced.

In audio applications, coaxial cable is used for digital signals, such as S/PDIF connections, offering stable quality and high fidelity. Its characteristic impedance is usually 75 ohms for video and 50 ohms for radio frequency.

The versatility and robustness of coaxial cable make it ideal for installations in homes, professional studios and live broadcast systems, where a clean and stable signal is required.

HDMI Cables

The HDMI (High-Definition Multimedia Interface) cable is the predominant standard for the simultaneous digital transmission of audio and video in high definition. This cable allows you to transport uncompressed video signals and multi-channel audio with superior quality.

HDMI cables include high-speed conductors that support resolutions ranging from 720p to 8K, plus DRM-protected content. Its compact design makes it easy to connect directly between modern devices such as televisions, Blu-ray players, video game consoles and computers.
