I have search on ebay for Mono to Stereo adapters and the first to arrive from the adapters is a RCA splitter which actually convert one signal into two so I can make it the sound become stereo however I could also use the splitter to split the Yellow RCA to be able to use multiple monitors. However in this vid I used the same RCA cables to turn mono left to be recorded on the right channel and added the RCA splitter to change it into stereo. http://www.chungdha.com
