Hi there First of all I want to say I'm a total noob regarding audio gear and naming conventions, but hopefully I'll be clear enough. I have two portable stereo speakers(connected with 3.5mm aux cable) and want to be able to play the left channel of music on one speaker, and the right channel on the other. I'm pretty sure I need a splitter which splits the incoming stereo into two mono(left and right) outputs. Here is an advanced scheme I draw to make myself clearer: How is this part called ? What do I have to look for in shops ? I know there are also splitters which have two stereo outputs, I want to make sure I don't get that one.
