Hello my name is Bob, and I would appreciate any help. I bought a used Tascam DP-32 with square trade insurance on eBay and I guess I got taken because seller wont take it back and the insurance wont honor their commitment that it should work. Sorry I bought it because all the lights work but it doesn't recognize any microphone audio in? No fader activity on the screen or anything on the headphones when recording. Any thoughts?
