Your monitor switches will let you hear either the source (what you are recording) or the tape (what you have already recorded) for each track. The recording mode switch lets you record on the track you choose to record on. If the mode switch is on when you push the red record button at the same time you push the play button, you will record the source. The mic/line knobs let you adjust the recording level (before you start recording), and the output knobs let you adjust the output to your board or amp. You need to have the input and output cables plugged into the correct jacks on the front (mic) or rear (line). Leave the simul-sync switches on normal until you get the basic recording down. Hope this helps. Give it a try and get back if you have problems.
