Abstract
Audio cables used in deploying audio equipment are typically selected to minimize signal transmission losses and may be chosen based on a distance between, and terminations of, an amplifier system and a loudspeaker system. Since this is usually unknown prior to deployment, multiple audio cables with different sizes and terminations and a variety of electrical extension cords to connect to a power supply line are transported. A loudspeaker adapter for the loudspeaker system and an amplifier adapter for the amplifier system can be used to interconnect the two systems via electrical extension cords. This precludes the need for transporting a large number of audio cables, and allows for interconnecting the loudspeaker and the amplifier systems without prior knowledge of the distance between the systems. Safety hazards and component damage can also be minimized by not connecting a hot terminal in the AC connectors of the loudspeaker and amplifier adapters.
