Izotope - Audio Restoration

I need to do an audio restoration of an old k7 meeting audio file, record years ago. About the 11 minute, begins the meeting and the audio is very low (need to be better. More clear). And the most important. All the meeting is join with another one (record in same k7 before and after delete), so the main audio it´s not clear and with a lot of noise. So need to be clear and high.
