Careful: (2 IN – 1 Out) doesn’t mean at the same time
So i'm looking for a device that maybe doesn't exists :/ I would like something that takes 2 input and has one output, so that whatever is playing on the input side i hear it without the need to select any source. So if input 1 plays A and input 2 plays B i would hear (AB) together, and if only input 1 is active then i only hear A. Unfortunately this device doesn't work like this, you still have to press the button to select the source. Too bad, otherwise the device works as described.
