Product Review; "To be able to connect my computer's audio signal to an audio board and modulate the levels it requires converting a 3.5mm stereo jack to a mono LXR port. SwitchCraft has a number of AV products but this is one of the simplest, easiest to use, and most affordable (check out the EBay link provided). If you are looking for a way to take your live performance or music sound quality to the next level AudioStix provide great utility."
