I wish to plug a mono 6.3mm cable from my shotgun mic (camcorder microphone) into a 3.5mm stereo camera. Do adapters work in reverse (converting mono to stereo or stereo to mono depending on where the sound is coming from)? If not, will the following item on ebay convert my mono microphone into a stereo sound that will then be plugged into the camera? It says that it is "Used for adapting a male 3.5mm Stereo plug to a female 6.3mm Mono jack" but does that mean the sound source must come from the 3.5mm plug or can the input actually be from the 6.3mm mono sound I will be plugging into the adapter. Thanks.
