JVC Victor JX-D77 D-terminal passive selector. I purchased this new about 10 years ago and used it with game consoles connected via D-terminal. I am selling it because I have disposed of the game consoles. I do not have an environment to test it at the moment, so I have not confirmed its operation. Please refrain from purchasing if you are looking for a perfect item or are overly concerned about its condition, as this is a used item.
