Amongst a box-lot of goodies I bought at an auction are 3 mono microphones surplus to my requirements so I'm intending to sell them on Trademe. (Marantz EC-33S, EC-12B and an uknown)
I'm not in the business of ripping people off so I want to test them before I list them. The only device I can use for this is my PC. When doing this, none of them seem to work. I find it hard to believe they're all faulty, particulalrly since they appear in good condition in their original cases complete with all accessories.
Could the reason for them not working be because I'm plugging a mono 3.5mm plug into a stereo socket. Is it worth investigating further ways to test them or are they simply duds?
