Abstract
Abstract A kit of electrical connectors enables an ordinary AC extension cord to conduct an amplified audio electrical signal between components of an audio system such as an amplifier and loudspeakers. The kit includes connectors adapted to engage the male and female ends of the extension cord. Each connector has a housing body, and is further provided with a standard audio-type connector such as a quarter inch jack post or XLR type fitting. Electrical wires extending through the housing body join the AC connector contact terminals to the audio connector contact terminals.
