I have some swan speakers that I want to use with bluetooth audio as well as computer audio. I purchased a logitech bluetooth device that turns it bluetooth but I want both to be connected. So I was looking to purchase this https://www.monoprice.com/Product?c_id=102&cp_id=10218&cs_id=1021808&p_id=669&seq=1&format=2 The issue is that it says that I can't use it to combine two signals or it might cause damage, is that true? I don't intend two audio signals to play at once but it could accidently happen. Any alternative ways to do what I'm trying to do?
