This is a selector for switching between both the input and output signal lines of audio devices. Both the input and output of the 3-RCA pin system can be switched independently. It can be combined in 9 ways, and is a must-have item for those with many amplifiers. There are no visible scratches on the exterior, etc., and it is good with just the degree of dullness (Kobayashi Hitoshi)
