I am preparing to set up a system and I have relized that the receiver I am going to use is one input short. There is a tape deck in the system. I have not really worked with many tape decks before. I was wondering if a tape deck will allow audio to pass through it when a tape is not being played. Then I could run an audio source through it and have 2 sources that only take up one input on the receiver. Then when they press play it will cut out the other source and play the tape. I will experiment with this when I get to this job but just wondering if anyone knows if this will work.
