I need to know what every thing is for becuase I am new to the recording scene but finaly got my own stuff set up becuase it was getting to be too expensive goin to studio's. I am using the Behringer XENYX 802 mixer and I am using it to record rap vocals and singing. Can anybody tell me what all these diff. things do? I need to know so I can make sure I am getting the best sound quality possible out of my mixer. I dont know what would be best to make the vocals the clearest and most powerful so if anybody can help me I would really appreciate it. Thanks.
