I need to record the speaker wile he is talking using a normal mic that plug in an amplifier. When i did a test run I inserted the mic into the mic jack of the computer and then outputted the sound to my amplifier to the speakers. In this way the sound was too low when outputting from the speaker. I also have to say that the mic wire is about 20 meters long. How could record in this situation. Those some have an idea? I thought the reason for the sound output is low because of the long distance there is from the mic to the PC and maybe I have to amplify the signal.
