Audio Cables serve as essential connection mediums for transmitting audio signals, broadly categorized into analog and digital audio cables based on signal transmission type. Analog audio cables use continuously variable electrical signals to transmit sound, primarily including RCA cables, XLR cables, and TRS balanced cables. RCA cables are commonly used in home audio equipment, while XLR cables with their balanced transmission and locking mechanism have become the standard choice in professional audio领域. TRS interfaces are available in different sizes for professional equipment (6.35mm) and consumer electronics (3.5mm). Digital audio cables transmit audio data through digital signals, mainly comprising coaxial cables, optical cables (TOSLINK), and
HDMI Cables, enabling completely lossless digital audio transmission that effectively avoids signal attenuation and interference issues present in analog transmission.
High-quality audio cables focus on signal fidelity in their design and manufacturing, typically using oxygen-free copper or silver-plated copper as conductor materials combined with multi-layer shielding structures to reduce external electromagnetic interference. Professional-grade audio cables often feature gold-plated connectors to enhance corrosion resistance and connection stability, while mobile cables for stage performances specially reinforce their jackets for improved pull resistance and wear durability. Different cable structures possess characteristic impedance values - digital coaxial cables require 75-ohm impedance, while microphone cables typically employ 600-ohm impedance design. These cables are widely used in home theater systems, professional recording studios, live performance equipment, and personal audio devices. From simple headphone connections to complex multi-channel recording systems, all rely on the reliable connectivity provided by various audio cables, making them indispensable components in the field of audio signal transmission.
