I have my carputer (laptop) connected to my sylfex auxmod and I want to keep this connection permanent. Is it possible to have another auxillary input jack for other things? I know I can use the microphone jack on my laptop, but isnt that mono...? (also It will be more distorted going through the laptop). Do they have audio cables that take in two sources and combine them (I don't think that works but I don't really know..). Or would my only option be some sort of audio hardware switch that can change the channels?
