A lead that is split so that one source can feed two outputs or a lead with a stereo jack plug at one end split into two mono connectors at the other (as used for mixing console insert points).

The history of the music industry is inevitably also the story of the development of technology. From the player piano to the vinyl disc, from reel-to-reel tape to the cassette, from the CD to the digital download, these formats and devices changed not only the way music was consumed, but the very way artists created it.”
