audiokábel

An audiokábel, or audio cable, is an electrical cable used to connect audio equipment for the purpose of transmitting audio signals. These signals can be analog or digital. Analog audio cables carry a continuously varying electrical voltage that represents the sound wave. Digital audio cables transmit discrete binary data representing the sound.

The most common types of connectors for audio cables include RCA, TRS (tip-ring-sleeve), XLR, and mini-jack (3.5mm). RCA connectors are typically used for consumer audio equipment like stereos and home theaters, often in pairs for stereo sound. TRS connectors, also known as phone connectors, are common in both consumer and professional audio, used for headphones, microphones, and line-level signals. XLR connectors are a professional standard, featuring a robust three-pin design commonly used for microphones and balanced audio connections, which helps to reduce noise over longer cable runs. Mini-jack connectors are widely used for headphones, portable music players, and computer audio.

The quality of an audio cable can affect sound quality, particularly with analog signals. Factors such as shielding, conductor material, and connector quality can influence the cable's ability to resist interference and maintain signal integrity. While the impact of cable quality is debated among audiophiles, proper shielding is generally important to prevent electromagnetic interference from degrading the audio signal.
