Audio cables are electrical cables or wires with specific characteristics to transmit audio signals

Coaxial cables have one conductor insulated with a dielectric material and then surrounded by the other conductor, usually referred to as the center conductor and shield.

Audio connectors are used to affix cables to other audio equipment, providing electronic signal transference and grounding protection

Video cable assemblies are used for the transmission of video signals, including monochrome, composite and component color video signals.

Specialized audio equipment is used in specific industries such as the recording industry, and for specialized applications such as voice digitizing and analysis

Digital audio systems electronically record and store audio signals such as voice, music, alarm, and security messaging for broadcast, editing, monitoring, and playback

Audio amplifiers and preamplifiers are units that amplify a sound signal, which is then sent to a speaker or another amplifier
