Connect multiple devices such as computers, tv and phone to a single speaker at same time.?
I have this mixer: https://www.velleman.eu/products/view/?country=es&lang=en&id=369006.
I plugged my phone to the input and plugged the speakers to the output channel. I played some music on my phone but there was no output comming from the speakers. The mixer is defective or not suitable for the purpose I intend?
