Microphone cables are a type of durable audio cable that commonly feature a single audio cable inside an outer casing. Microphone cables are available in a range of styles including single core and multicore. Microphone cables are commonly used to carry individual audio signals, for example from a microphone to an output. Microphone cables are ideal for attaching an XLR connector or jack, allowing them to be plugged into an amplifier or PA system to amplify vocals.

Where are microphone cables used?

Assembled microphone cables are found in both portable applications, where they are stored loose or on a cable drum (a spool used to carry different types of electrical wires) or are permanently installed. Microphone cables often feature a standard jack or XLR connector, allowing them to effortlessly connect to amplifiers and sound systems. Microphone cables are highly versatile and can be used in a wide range of areas including home and studio for recording, as well as venues in a live setting.

Construction of a microphone cable

• Core conductor: The vast majority of microphone cables have a pair of twisted copper wires, suitable for balancing the audio.
• Core insulation: Core insulation is used to isolate the single core and the outer screen. One method uses an extruded plastic sheath around the individual core, which reduces background noise.
• Core screening: The cable inside the core is individually screened to reduce crosstalk between cables and reduce any unwanted noise or hum.
